Pycnanthus.] CXIV. MYRISTICACEH (STAPF), 157 
Moreover, very little has since been added to our collections of African Myristicacee, 
and they are still one of the most imperfectly known families of the African floras. 
Their often considerable height, their dicecism and their inconspicuous flowers 
account probably for their neglect by the collectors; but as the seeds of some of 
them are enormously rich in vegetable fat, and others yield serviceable timber, more 
attention might be paid to them even from a purely economic point of view. 
Endosperm ruminate ; lateral nerves always conspicuous, 
Leaves with 15-60 parallel, usually very marked 
lateral nerves on each side; male flower-heads 
or umbels not supported by a disk-like base of 
an early deciduous involucre of bracts; seeds 
solid in the centre. 
Male flowers sessile, $ lin. long, in small heads, 
loosely clustered or congested on the secondary 
branches of more or less divaricate panicles ; 
anthers 2-4; fruit oblong; aril laciniate ; 
rumination-folds intruding radially . : - 1. Pyconanruus. 
Male flowers distinctly pedicelled, 13~2 lin. long, 
in small capituliform umbels, which are solitary 
or crowded into globose heads on the primary 
branches of very reduced panicles; anthers 
6-10; fruit much depressed; aril entire; ru- 
mnination-folds starting from near the chalaza 
(that is, descending from near the top) . . 2. SCYPHOCEPHALIUM.

on each side; male umbels supported by the disk- 
like base of the early deciduous involucre of

centre : : : . . .

Male flowers: Perianth obovoid or shortly clavate, 3—4-partite. 
Filaments united into a slender column ; anthers small, 2-4, adnate to 
the apex of the column, exserted from the perianth. Female flower: 
Perianth as in the male. Stigma sessile, indistinct. Fruit medium- 
sized; pericarp thick, fleshy, dehiscent; aril laciniate. Seed oblong, 
testa thin; endosperm ruminate, replete with fat, but destitute of 
starch (or almost so) ; rumination-folds intruding radially, Cotyledons 
free almost to the base, suberect.—Leaves more or less chartaceous, 
cordate at the base, glaucous beneath, with numerous subhorizontal 
lateral nerves and faint subparallel transverse veins. Inflorescences 
panicled, divaricate with clustered or more or less scattered heads of 
minute sessile flowers.
