description: <i>Cryptocarya glabriflora</i> Van der Werff, sp. nov. (Fig. 1) Cryptocaryae alseodaphnifoliae <i>affinis, sed foliis obovatis, coriaceis, subtus glandulo-punctatis, inflorescentiis majoribus, ad 9 cm longis recedit</i>. TYPUS. — <b>Madagascar.</b> Toamasina, Vatomandry, Commune Ambalabe, W of Sahamahirana stream, 19°09'33''S, 48°34'40''E, 21.XI.2004, <i>A. Randrianasolo, R. Ranaivojaona &amp;</i> <i>A. Razanatsima 902</i> (holo-, TAN; iso-, G, MO, P, US). DESCRIPTION Tree, to 30 m. Twigs angular or terete, glabrous, terminal buds densely and minutely puberulous. Leaves alternate, obovate to obovate-elliptic, 6-11 × 3-6 cm, glabrous, stiffly coriaceous, the base acute, rarely obtuse, margin flat, the apex rounded, the lower surface minutely but densely gland-dotted, lateral veins 4-6 on each side, reticulation raised on both surfaces, petioles glabrous, 9-14 mm long. Inflorescences 3.5-9 cm long, paniculate, branched from the base, glabrous; bracts along inflorescences mostly deciduous, 1.5 mm long, linear, pubescent. Flowers yellow-green, externally glabrous, tepals initially half-erect, in old flowers spreading, flowers 4-5 mm in diameter; pedicels short, from half the length of the floral tube to equaling it; tepals 6, equal, narrowly ovate, 1.5-2 mm long, glabrous outside, puberulous inside; stamens 9, all 2-celled, pubescent, <i>c.</i> 1 mm long, the filament very short, 0.1-0.2 mm, the anther cells large, the connectives slightly prolonged beyond the anther cells; stamens with the same length and width as the tepals and hidden behind them; 2 small globose glands present at the base of the inner three stamens; staminodia small, narrowly ovate, pubescent; pistil glabrous, the style to 1 mm exserted, receptacle tubular, pubescent near the rim, otherwise glabrous. Fruits unknown. REMARKS Only two species of <i>Cryptocarya</i> from Madagascar (including those previously placed <i>Ravensara</i>) have the combination of glabrous twigs and leaves and raised reticulation on both surfaces of the leaves. Of these two, <i>Ravensara macrophylla</i> Kosterm., only known from the fruiting type, differs in leaf shape (elliptic) and size (16-20 cm long). The other species, <i>C. alseodaphnifolia</i> Kosterm., is known only from the flowering type collection. Like <i>C. glabriflora</i>, it has glabrous flowers, a feature unknown in other members of the genus on Madagascar (although flowers are unknown in 13 species, their types having fruits only). <i>Cryptocarya glabriflora</i> differs in having stiffly coriaceous leaves (chartaceous in <i>C. alseodaphnifolia</i>, although Kostermans (1957) described them as coriaceous), leaves that are obovate to obovate-elliptic (elliptic to broadly elliptic in <i>C. alseodaphnifolia</i>), and densely and minutely gland-dotted on the lower surface (without gland-dots in <i>C. alseodaphnifolia</i>), and the inflorescences are 3.5 to 9 cm long (1-3 cm in <i>C. alseodaphnifolia</i> according to Kostermans (1957) although the isotype I have seen did not have inflorescences longer than 1.5 cm). <i>Cryptocarya glabriflora</i> is only known from the type collection, made in primary forest near Ambalabe, at mid-elevation on the east coast of central Madagascar.
