272 NATURAL HISTORY OF PLANTS. 



alternate, much imbricated, connate at base among themselves and 

 -with base of androceum. Stamens cr> ; filaments at base in short cupule 

 1-adelphous, in bud much contorted, corrugate ; interior sometimes 

 short, anthcrless ; anthers small, introrse, versatile, longitudinally 

 2-rimose. Germen free, 4-0-locular ; styles same in number, filiform, 

 elongated, at apex not thickened, stigmatiferous ; ovules in each 

 cell 1, inserted at internal angle, incompletely anatropous or sub- 

 orthotropous ; micropyle extrorse superior. Fruit drupaceous, meso- 

 carp but}Tous or resinous ; putamens 1-4, ligneous, exterior rugose, 

 muricate, aculeate or produced in rigid setae (penetrating into meso- 

 carp) 1-spermous ; seed subreniform ; embryo exalbuminous, fleshy, 

 oily, hippocrepiform, macropodal, radicle large clavate or ovate 

 tending towards apex of fruit ; tigella much attenuated, colli- 

 form inflexed ; plumule small. — Trees ; leaves opposite, digitate, 

 3-5-foliolate, folioles coriaceous, subentire or serrate-crenate ; sti- 

 pules or very caducous ; flowers in terminal racemes (Trop. America).

28. Anthodiscus Gr. F. W. Mey. — Flowers nearly of Caryocar, 

 smaller; corolla calyx-like, deciduous. Stamens gc, 1-adelphous at 

 base, afterwards in phalanges 5, alternipetalous ; central filaments 

 in each phalanx, much longer, inflexed ; exterior shorter, erect ; 

 anthers introrse, 2-locular. Germen 8-12-locular ; ovule in each 

 cell, subbasilar suborthotropous; micropyle extrorse, superior; styles 

 8-12, stigmatiferous at apex. Fruit coriaceous subfleshy, depressed 

 at apex. Seeds compressed at sides ; testa membranous, embryo 

 scantily albuminous, radicle very long, spirally contorted tending 

 towards apex of fruit ; cotyledons in middle bristled, short, notched- 

 inflexed. Other characters of Caryocar. — Trees ; leaves alternate, 

 digitate, 2-foliolate; racemes terminal (Trop. America). See p. 252.
