42. T.pilosum, 4. W. Hillin Kew Bulletin, 1910, 187. Perennial 
dwarf subshrub ; rootstock woody ; stems erect, unbranched or branched 
near the base, 3-4 in. long, densely pilose. Leaves ovate-lanceolate,

slightly amplexicaul towards the base. Flowers nearly sessile or on 
short peduncles in the axils of the bracts; bracteoles linear-lanceolate, 
acuminate, 1} lin. long, forming a small involucre. Perianth 14 ln. 
long, hairy outside; lobes 7 lin. long, narrowly ovate-lanceolate, hooded, 
margins slightly inflexed and membranous, glabrous within. Filaments

43. T. lycopodioides, Gilg in Baum, Kunene-Samb. Exped. 229. 
A low subshrub; branches about 1 ft. long, very much divaricately 
branched, prostrate, very densely hispid-pilose. Leaves few on elongated 
branches, very densely placed on short floriferous branches, very 
narrowly imbricate, lanceolate or linear-lanceolate, acuminate and even 
apiculate, about % lin. long, sessile, slightly decurrent, glabrous above, 
rather densely hispid-pilose below especially near the base. Flowers 
generally solitary at the apices of the branches, almost entirely covered 
by numerous much imbricated leaves. Perianth white, about 1 lin. 
long; lobes } lin. long, lanceolate, acute or subacute, dorsally hispid- 
pilose. Anthers sessile or subsessile, inserted at the base of the 
perianth-lobes. Style filiform, ? lin. long; stigma scarcely dilated. 
Fruit not seen.

This species is very close to 7. strigulosum, Welw., and the examination of - 
fuller suite of specimens may show the two species to be identical. 7. lycopodioides, 
however, can be distinguished from 7. strigulosum by the short densely leafy branches 
aud by the shorter and less distant leaves on the main stems. Gossweiler’s 1113 from 
Kiamballa, placed under 7. strigulosum, seems to be somewhat intermediate between 
the two species, though it can be more clearly placed with Welwitsch’s specimen. 
44. T. unyikense, Engl. in Engl. Jahrb. xxx. 306. Rootstock 
small, thick, erect; stems many, much-branched, longitudinally 
grooved, 12 in. long; branches 14 to 2} in. long, ascending at an acute 
angle, bearing 1-5 flowers, often irregularly cymose. Leaves 1-1} lin. 
long. Bracts smaller than leaves, triangular, acute, ciliolate. Perianth 
white, 1} lin. long; lobes triangular-elongate, obtuse, $ lin. long, 
margins inflexed, membranous, glabrous. Anthers about 4 lin. long. 
Style about 1 lin. long. Fruit ovoid, 12 lin. long, 1} lin. broad, dis- 
tinctly 10-nerved and with prominent reticulations between the nerves.
