 oblong-cuneatOj caducous. {Trop, America,^) 



V. NAPOLEONEJE. 



62. Napoleona Pal. Beauv. —Flowers hermaphrodite regular; 

 -receptacle turbinate, enclosing germen adnate within. Sepals 5, 

 marginally inserted, 3-angular, valvate. Petals 5, alternate, inserted 

 with calyx, connate in orbicular shortly 5-lobed corolla ; lobes longi- 

 tudinally multiplicate, valvate, denticulate at apex. Disk interior to 

 corolla duplex petaloid, consisting of 2 concentric crowns ; the exterior 

 composed of lacinise subulate-ligulate subfree or connate only at 

 base ; the interior connate in multilobed tube inflexed at apex ; both 

 connate with base of corolla and androecium and falling with them. 

 Stamens oftener 20 ('^ more rarely 25-oo "), in 5 alternipetalous 

 groups ; the stamens of each group generally 4, of which the 2 ex- 

 terior are fertile, the interior anantherous ; the filaments of all peta- 

 loid ligulate incurved; anthers of the exterior adnate introrse, 1-locu- 

 lar, 1-rimose. Germen inferior, 5- locular; cells oppositipetalous; style 

 erect short thick, 5-gonal, at apex dilated-peltate, 5-angular, stigma- 

 tose along 5 furrows. Ovules in cells oo , generally few (4), 2-seriate, 

 finally descending, with micropyle introrsely superior, or slightly as- 

 cending, with micropyle extrorsely inferior. Eruit baccate corticate, 

 crowned with calyx ; seeds few imbedded in pulp ; cotyledons of reni- 

 form embryo plano-convex fleshy ; radicle short retracted to hilum of 

 cotyledons. — Glabrous trees ; leaves alternate, entire or obscurely 

 sinuate, penninerved, epunctate ; flowers axillary, solitary or few 

 glomerulate; bracts under flower few, decussate-imbricate, larger from 

 the lower to the higher, often on both sides (as the sepals and some- 

 times the leaves) bearing an elliptic gland sessile to margin. (Trop. 

 west. Africa.) — Seep. 331. 



63. Asteranthos Desf. — Ylo-weYsnesLrlj of Napoleona; receptacle 

 shorter. Calyx gamopliyllous membranous, sinuate denticulate at 

 margin. Corolla widely rotate, oo -plicate, destitute of crown within. 

 Stamens oo , connate with corolla at base, oo -seriate ; filaments fili-
