Stamens 15, in pairs, the common filament flattened, oblong-ovate, 0.6 mm long, abruptly contracted into the filiform filament proper which is 0.2 mm long or less; anthers broadly ellipsoid, 0.3 mm long, glabrous, the connective prolonged as a slender filiform glabrous appendage, 1.5 to 1.7 mm long. Ovary ovoid, glabrous ; style stout, 2 mm long, apiculate. Fruit unknown. Kwangtung Province, Tung Sing, K. K. Ts'oong 2014, July 27, 1918, with the local name man ling shii. This is the first representative of the family to be found in China proper. It is apparently allied to Shorea cochinchinensis Pierre and S. harmandii Pierre, but is at once distinguished from both by its fewer-nerved leaves.

This species differs from Dipterocarpus vernicifluus in its more glabrous leaves and buds and generally smaller leaves, and from D. hasseltii in the smaller leaves and fruit and greater number of secondary veins. The three short wings of the fruit are also shorter than the similar wings in D. hasseltii and are not expanded nor reflexed as is the case in that species. 8. DIPTEROCARPUS CAUDATUS sp. nov.

This form is distinct by its small-sized, long-caudate-acuminate leaves, which are glabrous, elliptic, cuneate at base, 9 to 13 cm long, 2.5 to 5 cm wide; the long-caudate acumen about 1.5 cm long; secondary veins are about 10 pairs; petiole 1.1 to 1.5 cm long; stipules linear, ferruginous-pilose.

Very old and very young fruits picked up under the tree show this to belong to the section Sphaerales, and the leaves are sufficiently distinct to warrant its description as a new species. 9.

The short wings are very inconspicuous enlargements of the rim of the calyx-tube. Luzon, Tayabas Province, Pagbilao, For. Bur. 23841 F. Manuel, August 6, 1914 (type). Said to be known locally as apitong. This plant was represented by fragmentary material collected by Mr. H. M. Curran in Sorsogon Province, Luzon, in 1909. It was mentioned by me in 1911, 4 but it was not until 1914 that enough material was obtained for a full diagnosis. The following are referred here: Luzon, Laguna Province, For.

The leaf-form, venation, and hairiness of buds correspond very closely to those of Dipterocarpus gracilis Blume, as figured in Fl. Javae, t. 5. It is characterized by its fruit which has an obconical base. Mindanao, Agusan Province, Cabadbaran, Elmer 13498, August, 1912 (type), at 230 meters elevation. 11. DIPTEROCARPUS CUNEATUS sp. nov.

Terminal buds clothed with long, pilose, silky hairs. Secondary nerves about 13. Leaves 6 to 11 cm long and 2 to 5.5 cm wide. Fruit 5-angled, 15 to 18 mm long and of about the same diameter. Angles of fruit more or less distinctly developed into wings, but thick and hard. Basilan, Mount Basilan, at 500 to 600 meters elevation, For. Bur. 18S95 Miranda, August 27, 1912 (type), For. Bur. 18896 Miranda, Bur. Sci. 16128 Reillo, August, 1912. The wood is said to be harder than that of ordinary apitong and is used for general construction. This species suggests a form referred to by King in Journ. As Soc Beng. 62 » (1893) 99: "A Perak species (Herb. Scortechini mixed with No. 1478) represented by fruits something like those of D. fagineus Vesque, but with the calyx-tube winged, not angled." It is evident that the relationship here must be very close, but identity is doubtful. This species is our only representative of the § Angulati It seems noteworthy in that section in that the angles are developed until they resemble wings. It is most closely related to Dipterocarpua fagineus Vesque, of the Malay Peninsula and Borneo, but differs from that species in having slightly smaller fruits, which are more sharply angled and with more scantily developed venation in the fruit wings. 15.

Young shoots and seedling leaves ferruginous-hairy exceedingly like the same parts in D. vernicifluus. Fruit much the size and shape of that of D. marginatus, but more constricted at the top and with ridges produced into membranaceous wings, as in D. grandiflorus Blanco. Fruit 3 to 3.5 cm long and 2 to 2.5 cm in diameter, the two long wings 15 to 17 cm long and 25 to 28 mm wide. Luzon, Bataan Province, Mount Mariveles, For. Bur. 12S95 Curran & Merritt, August 1908 (type.) The type consists of three mature fruits, two young seedlings and one adult leaf, picked up under the parent tree. There has been but the one collection. As always, where the material is picked up under the tree, there is question of the accuracy of the diagnosis. However, the collectors were very careful and it has seemed desirable to give this collection a name. In 1911 * I published a note concerning this apparently distinct form. 17. DIPTEROCARPUS ORBICULARIS sp. nov. Arbor magna. Foliis suborbicularis vel obovatis, 9 ad 22 cm longis, 6 ad 11 cm latis, acuminatis, basi cuneatis vel rotundatis; nervis secondares 9 ad 12; nervis tertiariis parallelis vel reticulars ; pagina superiore glabra, inf eriore pilosa. Fructus alatus, alae membranaceae. A large tree with brownish tomentum on twigs, petioles and underside of leaves. Leaves mostly suborbicular, some obovate, 9 to 12 cm long, 6 to 11 cm wide, with crenulate margins; apex shortly and very bluntly acuminate; base rounded or cuneate. Secondary nerves 9 to 12 pairs ; tertiary veins parallel and reticulate. Petioles 2.5 to 3.5 cm long. Twigs, buds, petioles, and margins of leaves densely clothed with long pilose hairs. Upper side of leaf glabrous, except for a few scattered hairs along the veins. Lower surface very thickly covered with large stellate hairs, many of which are set on the tertiary veins. The secondary veins and midvein are clothed, for the most part, with pilose hairs. The secondary veins unite near the margin with a fine intramarginal vein, which is very much the same size as the tertiary veins and united with them. Fruit (immature) with membranous wings as in D. grandiflorus Blanco. Luzon, Camarines Province, For. Bur. 21719 Penas, Soriano and Abellanosa, April 26, 1914 (type).

All of these specimens were collected in Camarines Province and all were sterile, except Curran's specimen, which had fruit picked up under the tree.

They may well represent another species; but, for the present, it seems well to place them under this. Villamil 44, collected in the southeastern part of British North Borneo in 1915, seems to belong with the form just mentioned. 2. ANISOPTERA Korthals Key to the Philippine species of Anisoptera a 1 .

The flowers of this species are very much like those of Pentacme contorta, but are rather larger and have the ovary distinctly pubescent. It grows in much the same situations as P. contorta, and produces the same kind of wood. It is known in southern Mindanao as malacayan bianco. The large leaves and the rather large fruit are the characters by which the species is most readily recognized. 2. PENTACME CONTORTA (Vid.) Merr. & Rolfe.

This is a very little known form, of which sterile material was once collected in Tayabas. It is not certain that it should go in this genus and will remain in doubt till more complete material is collected. 5. SHOREA Roxb. Of about one hundred species in this genus, twenty-one are known from the Philippines. These include several of our most important woods. Most red lauan and mangasinoro, all tanguile and guijo, and some kinds of yacals and white lauans are produced by species of Shorea. Collectively, the members of this genus produce at least 35 per cent by volume of the stand of our commercial forests. There is considerable variation in leaf, bark, and wood characters. Some of the species have been collected only in flower, others in fruit, and yet others only with sterile material. This has made it difficult to be sure of the specific identification in a number of instances and has made it very difficult to prepare a key to the Philippine species. In a number of cases, it has not been practicable to refer collections to any particular species, and most of these cases have been left out of consideration in preparing the key. I have found it necessary to use wood characters for the main divisions of the key, in default of sufficiently sharp leaf differences.

The leaves are coriaceous, glabrous above, lighter colored, sometimes almost glaucous, and slightly pubescent beneath, elliptic-lanceolate, acuminate at apex, cuneate at base, 6.5 to 9 cm long, 2.4 to 3.4 cm wide; petiole brownish, sometimes pubescent, 12 to 15 mm long; secondary veins 8 or 9 pairs, tertiary veins parallel and reticulate.
