272 NATURAL HISTORY OF PLANTS. 
alternate, much imbricated, connate at base among themselves and 
with base of androceum. Stamens © ; filaments at base in short cupule 
l-adelphous, in bud much contorted, corrugate ; interior sometimes 
short, antherless; anthers small, introrse, versatile, longitudinally 
2-rimose. Germen free, 4—6-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 butyrous or resinous; putamens 1-4, ligneous, exterior rugose, 
muricate, aculeate or produced in rigid setæ (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 0 or very caducous ; flowers in terminal racemes (770p. America).

28. Anthodiscus G. F. W. Mry.—Flowers nearly of Caryocar, 
smaller; corolla calyx-like, deciduous. Stamens o, 1-adelphous at 
base, afterwards in phalanges 5, alternipetalous; central filaments 
in each phalanx, much longer, inflexed; exterior sborter, 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 (Zrop. America). See p. 252.
