GEOLOGIC RECONNAISSANCE OF MINDANAO AND SULU. 479 V. CLIMATE. It is difseiilt to discuss the meteorology conditions of Mindanao in a general way. The fairly regular and distinctly marked seasons which prevail in Luzon do not seem to obtain in Mindanao. The following table is taken from the monthly reports of the Philippine Weather Bureau Rainfall, in millimeters, at Mindanao and Still stations during 1905. Month. Zamboanga. Isabela. Jolo. Davao.

Zamboanga Peninsula is fairly well forested, if the plain which has been cultivated for a long time is excepted, but the forest of this region is not by any means as luxuriant as that of the Agusan and Davao Valleys. The densest forests in the Philippine Islands, with the possible exception of portions of Mindoro, are probably to be found in the latter districts. I was not in the country for a sufficient length of time to render any statement I might make in regard to the healthfulness of various parts of Mindanao of value. The low country in the river valleys and the lake region to the south of the Cotabato is probably not as healthful as the highlands of the Lanao region. Mosquitoes abound in many parts of the former territory and great precautions must be taken against them. The Cotabato River has a particularly bad, but I think unreserved, reputation in this respect. I had no fever nor any sickness whatever during the five months I was in Mindanao, but both native and American troops have suffered considerably from malaria. A table of the temperatures for the various stations of the island follows

Leaves coriaceous, elliptic, oblong or ovate-oblong, on the upper surface glabrous, on the lower surface glabrous except at the sparsely pubescent midrib, margins undulate, nerves on both sides very prominent, veins parallel at rightangles to the nerves, midrib depressed above, prominent beneath; length 12 — 23cm, width 6 — 12 cm; petiole 3,5 — 4 cm long, densely hirsute, consisting of tufts of stellate hairs, some short some long. Stipules 4 cm long, 9 mm wide, externally densely hirsuto-tomentose. Fruit ovoid, wings 13 cm long, 2 cm wide; tube of the fruiting calyx with 5 protuberances in its upper portion. Luzon, Prov. of Tayabas, Guinayangan, growing on sandy soil, sandstone (Merrill no. 2031 with fruit in April), (Merrill no. 2004). The nearest ally of this is Dipterocarpus Warbiirgii Brandis, from which, however, it differs by having smaller fruit. In D. lasiopodus the densely hirsute -pubescent petiole is most peculiar. Merrill says that the wood of this tree is used for bancas (native canoes) and that the tree occurs frequently in forests. 2. Dipterocarpus speciosus Brandis. Luzon, Prov. Principe, Baler (Merrill no. 1149; a. 1903). 3. Dipterocarpus velutinus Yid. Luzon, Prov. Bataan, Dinalupihan (Merrill no. 1479; February 1903). Prov. Zambales, Subig (Merrill no. 1754; April 1903). Anisoptera Korthals. 1. Anisoptera ealopliylla Perk. n. sp. A high forest tree (ex Warburg); branches slender at first with sparse, stellate hairs.

Fruit globose, 1,5 cm diam., calyx segments uniting below the apex of the fruit; wings 5, 7 — 8 cm long, 1,8 cm wide, obovate-lanceolate, on both surfaces pubescent; 2 segments of fruiting calyx much longer than the others, with 3 prominent longitudinal nerves joined by conspicuous transverse veins which are somewhat oblique. Middle Luzon, Prov. Zambales (Warburg no. 13429 with fruit in April); Luzon, Prov. of Bataan Dinalupihan (Merrill no. 1518). This is closely allied to Anisoptera thurifera Blume but has larger leaves with more numerous nerves, and the apex of the petiole is enlarged. A. thurifera has, moreover, on the lower surface of the leaves, on the inflorescence and on the petioles, minute, round scales which are wanting in this species. 2. Anisoptera Vidaliana Brandis.

1920] 127 in. TWO NEW SIAMESE PLANTS. By H. N. Ridley, C.M.G., F.R.S. I have found the following undescribed species in a small collection sent me by Dr. F. W. Foxworthy, Forest Research Officer, F.M.S. They were obtained by a collector of the Forest Department who accompanied the expedition of the F.M.S. Museums Department to the northern half of the Malay Peninsula in 1919 (antea pp. 65-126). ANONACEAE. 1. Miliusa concinna, sp. nov. Branches slender, bark dark brown lenticelled ; young parts pubescent. Leaves rather distant oblong oblanceolate, blunt or subacute, base narrowed unequally bluntly bilobed, membranous to subcoriaceous, thin, glabrous or when young pubescent on the midrib beneath ; nerves fine inconspicuous, 8 pairs, 4 in. long, 1-5 in. wide ; petiole hairy or glabrous, -1 in. long. Flowers solitary or 2 on tubercles ; pedicel slender, hairy, -5 in. long. Sepals ovate -12 in. long, hairy,. Petals oblong, tip rounded, hairy on both sides, -25 in. long. Stamens about 7 whorls, 20 in all ; anthers short, narrow, connective broad, flat irregularly rounded. Pistils 20, densely woolly on the top. South-western Siam : Hat Sunuk near Koh Lak (Hamid No. 3820) ; Koh Lak (Hamid No. 3802). Native name Pom rimpah. The specimens under No. 3802 differ in being much more hairy, the branches being densely 50 ft. tomentose, and the leaves hairy on the back ; «while No. 3820 is almost completely glabrous, only the young parts being pubescent. DIPTEROCARPACEAE. 2. Pachynoecarpus grandiflorus, sp. nov. Leaves oblong thin but stiff coriaceous elliptic acutely short acuminate, base narrowed, blunt ; nerves 12 pairs prominent beneath, reticulations conspicuous beneath, 6 to 8 in. long, 2-5 to 4 in. wide ; petiole thick -5 in. long, pubescent. Panicle dense, terminal compact, 3 in. long, 4 in. wide, pubescent ; pedicel -1 in. long. Calyx pubescent mealy, • 1 in. long, lobes lanceolate acute, cleft nearly to the base. Petals -75 in. long, -25 in. wide, oblong spathulate tip broad rounded, glabrescent. Stamens 15 in 2 rows. Ovary cone-shaped free from sepals, puberulous. Style short, thick ribbed ; stigma rather large. Fruit (unripe) ovoid not corky. Calyx entirely covering the nut except the extreme tip, lobes thin, ovate rounded, whole fruit -75 in. long, lobes free part -1 in. long. Peninsular Siam, Klong Wang Tapoh in Renong. (Hamid No. 3787) . Native name Mai Sak. Perhaps nearest to P. Stapfianus but the leaves are thinner and have more nerves. It has larger flowers than any species I have ever seen.
OCEANIC DISPERSAL OF PLANTS. 287 fruit of the former is described as having a hard, blood-red sarcocarp, with the mesocarp traversed by stout vessels from the thin crustaceous endocarp, and this description applies fairly well to the skeleton fruit from the New Guinea drift, save that the endocarp of this is more woody. AVhen fresh this must have been nearly or quite two inches and a half in diameter. Beccari mentions, loc. cit., that he never found the fruit attached to the plant, but always picked it up from the ground. The largest fruit of the order described is that of Macrococculus pomiferus, Beccari (Malesia, i. p. 161). This is also drupaceous and globose or pyriform, and about four inches long by three inches thick. It is from the same country. BIXINE^E. Pangium edule, Beinw. Pangium edule, Reinw. ; Miq., Fl. Lid.

Miquel states that this is generally spread in the Malayan Archipelago, from Sumatra to the Celebes, Amboina, and Ceram, though rare in Amboina ; and it is also common in the Philippines ; but hitherto it has not been found either in Continental Asia or in Australia. It is commonly cultivated by the Malays for the sake of its large, oleaginous seeds, which are an important article of food. The fruit varies considerably in size and shape, according to Blurne, who represents one nine inches long and six inches across the middle. It has a thick fleshy indehiscent pericarp, which must decay before the seeds become free. The broad, irregularly wedge-shaped seeds measure two inches or more in their greatest diameter ; and they are provided with a crustaceous testa apparently impervious to water. Only one seed is in the collection, and that is sound, though it has probably lost its germinative power. In its present state it floats with about half its body submerged. Good flowering specimens of this tree are wanted for the Kew Herbarium. DIPTEROCARPE.E. Vateria papuana, Dyer. (Plate LXIV., B.) Vateria papuana, Dyer, ante, p. 123. Vatica papuana, Dyer in Journ.

In the first place, only flowering specimens of this very distinct Dipterocarp were communicated to Mr Dyer, and as the floral structure agreed with Vatica, it was referred
— 324 — Fruit one-seeded by abortion, as a rule spherical of depressed spherical, rarely conical >'. kanneliyensis) or pointed (S. reticulatus) , roughish because of a pattern of minute, polygonal areas ; sepals persistent, either unaltered, adpressed to the base of the fruit or patent or hardened and slightly enlarged, pointing downward, in N. kanneliyensis and S. reticulatus much thickened and pointing downward. Cotyledons small and simple or large, lobed, dissected and folded, green or red. No albumen. Germination : the fruit with thick pericarp (S. kanneliyensis, S. reticulatus, perhaps S. wightii) dehisce by valves, along the depressions : the thin <»r thinner skinned fruit crack irregularly, even when they are ribbed in immature stage. The hypocotyledon lengthens considerably and lifts the cots above the ground; they either remain in the pericarp (S. kanneliyensis) or unfold, become horizontal, fleshy, large, thick, wrinkled and incised, red or green. Cots equal or unequal. In some species at the base inside of the pericarp a Meshy cup with laciniate margins ; sometimes a fibrous mass between the cots (Heim, Brandis). The first leaves are, as in Vatica, whorled. Distribution : Wet zone in the S.W. parts of the island, in the Adam's Peak jungle and in the Knuckles Mts. at altitudes from sea leavel to 1700 m Ecology : Always in the wettest parts, many along streams and streamlets in the Occurrence independent of depth of soil or kind of soil. Often in small populations far apart. Only a few reach timber size. They flower in definite periods after ice or twice a year. Flowers few. Fruit setting is rare to very rare (hence ire rare). Pollination by beetles, bees, butterflies. Since the inception of the genus Stemonoporus by Thwaites in IS54, it has moved through Valeria and Vatica and has nowadays been re-established as a proper genus. This implies that the generic delimitations, especially in the Vatica group (Vatica, Stemonoporus, Cotylelobium) are not satisl'actorilv solved. The trees of the three genera look much alike, and are in Ceylon known under one collective vernacular name : Mendora. Whereas in Shorea and Hopea all genera with more or less similar fruit characters are combined, this is not the ease in the Vatica group and this inconsistency is one of the reasons of the unsatisfactory situation. Thwaites originally recognized 11 species under Stemonoporus and 3 under Monoporandra. Under the influence of Bentham, he referred them all to Valeria in the Addendum of his book in 1854, even quoting Bk.muam as the author of the new combinations (this is under the latest Rules not ad missable. the combinations should be printed to be valid and not only suggested, as Bentham did). Thwaites even went one step further than Bentham and moved also Monoporandra to Valeria. Thiselton-Dyer followed suit, but meanwhile A. de Candolle had reduced Stemonoporus to Vatica, but — like all other botanists — up to Alston, kept Monoporandra separate. In his Addendum Thwaites added (under Valeria) 3 new species, of which Valeria

Ovary 3-celled, cells 2-ovuled. Style subulate. Fruit a 1-seeded nut closely embraced by the bases of the greatly enlarged sepals. Cotyledons fleshy unequal, one embraced by the other, hypogeal in germination. 1. S. robusta, Gaertn, Sarjom, K., S.; Sakua, Kharw ; The Sal tree. Throughout the area. In many of the deep valleys of Singbhum, Bonai and Gangpur it attains 12 ft. girth and 120 ft, high, the soil being a deep loam derived from the decomposition of gneissic ropks. On the hills of clay schist it is a stunted tree attaining 30-40 ft., and it occurs in a very stunted form on the top of Parasnath at 4,400 ft. elevation which is above the elevation it generally attains in the Himalayan region. Large trees are now very scarce in the other districts where the forests have been mostly ruined and the trees are mostly coppice shoots which frequently flower as mere bushes. Gamble records a tree in a sacred grove in the S. P. (at Talpahari) 10 1/2 ft. girth and 120 ft. high. Fl. March-April, in some years the flowering extends into May. Fr. June-July. Nearly or quite leafless in March. Stipules 1/4”-1/2” oblong, covering the young buds. The panicles arise direct from the old wood and on the new shoots, the flowers are unilateral on the branches." Petals with a twisted acumen, free with overlapping bases. Filaments very swollen below. Campbell says the best time for cutting is October, and that the timber is then much more durable. The logs should, of course, always be barked immediately after felling. The fuel and charcoal are excellent, and the latter is said by the Kols to be the best available for iron smelting. The seeds are eaten but are said not to be very wholesome. It was previously much tapped and destroyed for resin before the reservation of the forests. The resin (dunra, K.; sarjom lore, S) is used in medicine and for caulking. The leaf is the usual covering of the Kol cigarette (fikr). The seed should be sown as soon as ripe, but the earliest to fall are usually bad. The stalks of the cotyledons are very long, and if the primary shoot is injured or dies subsequent shoots arise from their axils. The first pair of foliage leaves are opposite. 178
