160 CXIV. MYRISTICACEE (STAPF). [Pycnanthus. 
deciduous; heads globose or ovoid, densely congested, 1-14 lin. long. 
Andreecium shortly exserted ; anthers 3-4, Female plant unknown. 
Upper Guinea. Liberia: Fishtown, near Grand Bassa, Dinklage, 1624 ! 
The facies of the leaves and branches of this plant are so different from the other 
species of Pycnanthus that I suspect it does not belong to that genus. 
4, P. Schweinfurthii, Warb. in Ber. Pharm. Gesellsch. Berlin, 
(1892), 223 (name), and in Engl. Pf. Ost-Afr. B. 271, C. 180. A tall 
tree. Leaves and inflorescences unknown. Fruits clustered, sessile, 
ellipsoid, 1-14 in. long, 1-1} in. in diam.; pericarp 24-3 lin. thick, 
almost glabrous; aril laciniate down to the middle or to 4. Seed 
obovoid-ellipsoid, up to 1 in. long, 6-8 lin. in diam.; testa shining, 
grooved, reddish-brown; endosperm sparingly ruminate; starch very 
scanty; cotyledons suberect with undulate margins.—Warb. in Nov. 
Act. Acad. Nat. Cur. lxviii. 260, t. 10, figs, 1-3. 
South Central. Congo Free State: by the Assika stream, in Niamniam 
Country, Schweinfurth ! 
Similar seeds covered with their arils were sent by the late Mr. Mahon from 
Uganda, but they are smaller, mostly 9-10 lin. by 6 lin., and even the largest always 
less than 1 in. in length. The tree from which these seeds were collected is of fine 
appearance, but the timber is not much valued. 
5. P. Mechowii, Warb. in Nov. Act. Acad. Nat. Cur. Ixviii. 261, 
t. x. figs. 1-2. Seed ovoid, brown, faintly grooved, 11 lin. long, 64 lin. 
in diam. ; testa black, 4 lin. thick ; rumination-folds rather thick. 
Lower Guinea. Congo Free State (or Angola?): without precise locality, 
Mechow. 
2. SCYPHOCEPHALIUM, Warb. in Ber. Deutsch. 
Bot. Ges. xiii. Generalvers.-Heft, 84. 
Male flower: Perianth funnel-shaped, 3-—5-partite. Filaments 
united into a column ; anthers 6-10, adnate to the column and as long as 
the stipes or slightly shorter. Female flower: Perianth as in the male, 
but with minute triangular bracteoles at the base. Ovary tomentose ; 
stigma 2-lobed, Fruit very large, depressed; pericarp very thick, 
fleshy, indehiscent; aril completely covering the seed, entire. Seed 
depressed ; testa woody, not very thick; endosperm ruminate, replete 
with fat, but destitute of starch; rumination-folds intruding from 
the chalaza downwards, Cotyledons divaricate.—Leaves chartaceous, 
with spicular cells, which in the dry state appear as slight prominences, 
particularly below ; lateral nerves joined by distinct arches close to the 
margin. Flowers pedicelled, in pseudo-capitate umbels, sometimes 
several of them crowded into larger heads; heads in short sparingly 
branched panicles or, by the reduction of the lateral branches, solitary. 
Bracts and, in the female, bracteoles present.
