172 xxiii. TERNSTR(EMiACE^ (oliver). [Caraipa. 



veined, with transverse reticulation. Flowers in a small, racemose, subter- 

 minal panicle. 



A small tropical American genus, to which I refer with little hesitation the species here 

 described from a specimen collected in Nigritania by the late Dr. Baikie. The anthers of 

 this plant remind one very much of those characteristic of Humiriacecs. In other respects 

 the African plaut agrees well with Caraipa, excepting in the presence of stipules, denoted 

 by their lateral scars. I think, however, there are traces of stipules in at least one Brazilian 

 Caraipa. 



I.e.? africana^ Oliv. Extremities terete, rugulose, pubescent at 

 first. Leaves coriaceous, broadly elliptical, very obtuse or slightly retuse ; 

 base broadly rounded, subcordate, with a gland at the apex of the (subpel- 

 tately attached) petiole, puberulous or glabrescent above, shortly and densely 

 hoary-tomentose beneath, lateral veins numerous, parallel, connected by 

 rather obscure transverse veinlets, 2^-3 in. long, lf-2 in. broad ; petiole sub- 

 terete, above \ in. Stipules deciduous. Flowers in a small, tomentose, ra- 

 cemose panicle from the axil of an upper leaf, much shorter than the leaf; 

 short lateral branches of the panicle few-flowered ; pedicels equalling or 

 shorter than the sepals. Buds \^ in. long. Fruit not seen. 



Upper Guinea. Niger region, Dr. Baikie ! (No precise locality.) 



The leaves are similar to those of Dipterocarpea or Tetracera, though not scabrous. 



Okder XXIV. dipterocarpea (by Prof. OHver). 



Flowers regular, hermaphrodite. Calyx 5-fid or 5-partite ; lobes imbri- 

 cate or subvalvate, in fruit usually enlarged, one or more of the calyx-lobes 

 growing out into a wing. Petals 5, contorted, free or slightly connate be- 

 low. Stamens definite or indefinite, hypogynous or (in Ancistrodadus) peri- 

 gynous ; filaments often dilated below, free or slightly connate ; anthers 2- 

 celled with equal valves or the inner shorter, dehiscing longitudinally or 

 towards the apex. Ovary free with a broad base or slightly adherent (inferior 

 in Ancistrodadus), 3-celled with 2 ovules in each cell or 1 -celled with 1 or 

 more ovules. Style entire, 2-fid or 3-fid, rarely styles 3, distinct {Andstro- 

 dndus). Fruit free or adherent, indehiscent or dehiscent, 1- rarely 2-seeded. 

 Seed exalhuminous ; embryo with equal or unequal, straight or plicate, 

 thick or foliaceous cotyledons, rarely {Andstrodadus) with an abundant 

 folded albumen. — Trees or scandent shrul3S, often resinous. Leaves alt ersate, 

 entire, penniveined, usually with small stipules. Flowers rather small, in 

 axillary or terminal panicles. 



An important forest Order in the hottest parts of India and the Archipelago. The re- 

 markable genus Lophira is peculiar to Africa.
