partial inflorescences 2-flowered, red; sterile flowers subspinescent. 
Perianth } in. long. Staminodes obovate, lacerate at the top. Ovary 
acutely ovate, sparsely hairy.—Lopr. in Malpighia, xiv. 442.

pischil. British Central Africa: N yasaland: Nyika Plateau at Nymkowa, 6500 ft., 
MeClounie, 46 ! 
The type of Lopriore has not been seen.—In McClounie, 46, referred here by 
description; stems not scabrid ; spikes high-red; barren flowers rigid, prickly even 
in young flower.—The colour suggests that his plant may be a form of Baker’s 
“rubella”? = Centema biflorum, Schinz; but that has a much softer spike and a 
scabrid stem. 
5. C. glomerata, Lopr. in Lngl. Jahrb, xxvii. 49, t. 1H. Leaves 
decussate, 1 by ,; in., narrowly linear. Inflorescence subglobose, 2 in. 
long, 3 in. thick, dense, made up of short-peduncled heads; flowers 
yellow-red. Perianth 4-} in. long; segments acute, hardened at the 
base, sparsely hairy on the back. Staminodes (between the filaments) 
obovate, lacerate at the top. Ovary top-shaped, hairy.—Lopr. in 
Malpighia, xiv. 443. 
Lower Guinea. Angola: Huilla, Antunes. 
This species is contrasted by Lopriore with C. polygonoides (= C. biflora, 
Schinz); but it does not appear to have a tubercular scabrid stem. 
14. PSILOTRICHUM, Blume; Benth. et Hook. f. Gen. PI. iii. 32. 
Flowers perfect, solitary ; bracteoles 2, ovate, much shorter than 
the flower. Perianth scarcely } in. long; segments 5, elliptic-oblong, 
muticous, rather thick, glabrous or sometimes minutely hairy. Fila- 
ments 5, linear, at the base lanceolate, united by an acute sinus 
into a cup, without staminodes between them; anther-cells 2, short. 
Ovary ovoid or subovoid, glabrous or obscurely granular at the top; 
style shorter than the ovary; stigma small, capitate; ovule 1, sus- 
pended from a basal funicle. Capsule thin, imperfectly circumscissile ; 
seed lenticular; embryo curled—Herbs or small shrubs, Leaves 
opposite. 
Species 20, in the warmer parts of the Old World.
