64 NATURAL HISTORY OF PLANTS. 



spermous ; seed scantily albiimiuous ; embryo straight (green) ; 

 cotyledons plano-convex ; radical short superior. — Herbs ; rliizome 

 perennial ; leaves alternate, membranous, penuinerved, serrate ; 

 stipules intrapetiolar, adpressed, striate ; flowers in terminal 

 racemes, sometimes simple, more rarely cymiferous ; pedicel short, 

 reflexed after anthesis. (Mountainous India.) See p. 45. 



II. HUGONIE^. 



3. Hugonia L. — Flowers regular, 5-merous ; receptacle convex. 

 Sepals imbricate, acute or obtuse. Petals alternate, contorted, or 

 imbricated, often fugacious, sometimes more or less thickened at 

 base or inwardly rather prominent-costate, exterior usually glabrous, 

 interior scantily or sometimes more richly pubescent villose. 

 Stamens 10, 2 -seriate, all fertile ; filaments connate at base in a 

 short tube, outwardly naked, or between the petals more or less 

 glandular-thickened ; anthers introrse, 2-rimose. Grermen superior ; 

 cells 3-5, alternipetalous ; style 5-partite ; branches stigmatiferous 

 at apex, more or less thickened ; ovules in each cell 2, descendent, 

 sub-superposed or oftener collateral ; micropyle extrorse superior, 

 blocked by thick obturator. Fruit drupaceous, more or less fleshy ; 

 putamens 3-B, ligneous or osseous, 1, 2-spermous; seed descendent; 

 albumen fleshy ; embryo straight or curved ; cotyledons foliaceous. — 

 Trees or shrubs, sometimes scandens ; leaves alternate, penuinerved, 

 entii'e or serrate, glabrous or tomentose ; stipules small, generally 

 caducous ; flowers in simple composite-cymiferous racemes, terminal 

 or axillary, sometimes shortly subsessile; peduncle bracteate or 

 naked; the 1, 2 most inferior or its branches changed into spiral 

 recurved hooks. {All trop. reg.) See p. 46. 



4. Ochthocosmus Benth. — Flowers nearly of Hugonia ; petals 

 persisting round fruit, more or less rigid or indurate. Stamens 5, 

 surrounded at base with very short glandular ring. Germen 

 3-5-locular ; cells 2-ovulate, undivided or more or less deeply 

 2-locellate by spui'ious septa ; style simple, stigmatiferous at apex, 

 very shortly 3-5-lobed Capsule septicidal 3-5-valved ; carpels 

 more or less septate. Seeds 1, 2, variously appendiculate or winged ; 

 embryo scantily albuminous , . . ? Glabrous shrubs ; leaves alternate,
