21B NATURAL HISTORY OF PLANTS. 



Conocephalus ; perianth tubular, cylindrical, ovoid or urceolate, some- 

 times obovoid, membranous or rather thick fleshy, apex either entire 

 and sometimes perforated with a very small aperture, or more rarely 

 1-3-dentate. Gormen free ; ovule either quite basilar or orthotropous, 

 or somewhat laterally inserted ; micropyle always apical. Fruit 

 drupaceous, enclosed by persistent and enlarged calyx, closely 

 packed or adnate at base. Seed erect or ascending ; hilum basilar 

 or somewhat lateral ; cotyledons of straight exalbuminous embryo 

 plano-convex subequal; radicle superior short. — Trees or shrubs, 

 sometimes climbing, lactescent; leaves alternate simple (of Pourouma), 

 ovate or cordate or obovate, glabrous or pubescent, petiolate ; 

 stipules axillary connate in one obliquely amplexicaul, caducous; 

 inflorescences axillary capitate ; capitules glomeruliferous ; peduncles 

 oftener 2-nate, simple or 2-chotomous ; branches capituliferous. 

 (Trop. South America.^) 



GO. Cecropia Lcefl. 3 — Flowers dioecious (nearly of Coussapoa 

 or Conocephalus) ; males 2-androus ; calyx tubular or narrow 

 conical, at apex subentire or shortly 2-dentate, sometimes more 

 deeply 2 -fid. Stamens short ; filaments erect ; anthers introrse, 

 2-rimose. Female calyx tubular entire or subentire, subiucrassate 

 at apex and there perforated. Germen free, enclosed by calyx ; 

 ovule inserted under apex of cell descending, micropyle extrorsely 

 superior ; style terminal or slightly lateral short, apex stigmatose 

 simple variously capitate-penicillate. Fruit dry, enclosed by calyx, 

 hence subdrupaccous ; seeds, etc., of Coussapoa. — Trees or shrubs; 

 juice milky ; branches terete, fistulous between the nodes ; medulla 

 hollow, here and there septate ; leaves alternate, more or less peltate, 

 palmatilobed or digitate ; petiole often callose at base ; stipules 

 connate in one wide spathelike amplexicaul, deciduous ; scars 

 annular; flowers axillary crowded; peduncles 1, 2-nate, at apex 

 subumbellately 2-co -rimose ; umbels (spurious) single, the younger 

 enclosed by spathiform caducous bract; branches (receptacles) 

 amentiform subcylindrical glomeruliferous; males generally more 

 slender than the females. (Both trop. Jmericas?)
