170 NATURAL HISTORY OF PLANTS. 



oblong introrse uniform. Germen sessile subcentral cc-ovulate ; 

 style short thick curved ; stigma truncate concave, minutely ciliate. 

 "Legume broad oblong-falcate compressed coriaceous-subligneous, 

 replete within between seeds, 2-valved. Seeds transverse oblong 

 compressed ; inner covering coriaceous shining close-fitting ; outer 

 samariform loose membranous, produced at apex into a truncated 

 falcate wing reaching to margin of valves, base continuous with very 

 short funicle ;" albumen thin ; cotyledons flat oblong, cordate at 

 base ; radicle short straight. — A lofty ferruginous-velvety tree ; 

 leaves imparipinnate ; leaflets oo-jugate ; flowers rather large in a 

 large much-branched terminal raceme {Brazil). See p. 89. 



22. Thylacanthus Tul. — Flowers of Batesia ; sepals 4, 5, mem- 

 branous petaloid or rather thick, imbricated. Petals 5, somewhat 

 unequal, imbricated. Stamens 10, free or connate to a very small 

 height from base ; filaments inflexed in bud ; anthers uniform. 

 Germen central, shortly stipitate, cc-ovulate; style elongated, in- 

 volute in aestivation ; apex peltate stigmatiferous. Fruit .... ? — 

 Small trees, unarmed ; leaves paripinnate ; flowers in compound 

 corymbose racemes at extremities of branches ; bracts thick spiral 

 very caducous ; bractlets 2, either concave, rather thick, connate on 

 anthesis into a 2-lobed involucre persistent below flower (Eutftyla- 

 cant/ius), or coriaceous very thick ivory-like, forming a globe before 

 anthesis, persistent opened by anthesis {Die;/ mix-), inclosing a 

 younger flower-bud {Northern Brazil, southern Venezuela). See p. 90. 



23. Campsiandra Bexth. — Receptacle campanulate, lined by a 

 disk. Sepals 5, imbricated. Petals 5, subequal imbricated. 

 Stamens co (usually 15-20), perigynous ; filaments free glabrous 

 exserted; anthers introrse. Germen subcentral free, shortly stipi- 

 tate, cc-ovulate; style terminal ; stigma minute or dilated. Legume 

 large compressed, straight or falcate, coriaceous or woody, 2-valved. 

 " Seeds exarillate exalbuminous ; radicle straight ; cotyledons flat, 

 obliquely or evenly cordate." — Unarmed trees ; leaves alternate im- 

 paripinnate ; stipules minute, very caducous ; flowers in compound 

 corymbose much-branched terminal racemes; bracts caducous {Tro- 

 pical America). See p. 91.
