THE TRIUMFETTAS OF AFRICA. 251 
В. rugosa, nob.: folia supra rugosa, nervis stellato-pilosis ceterum pilis 
plerumque simplicibus setulosa, exsiccando intense viridia. 
Angola: Malange Distr.; Toba Quatungi, Gossweiler, 1447! 1448! 
between Sanza and Malange, Pogge, 11! 
13. T. rhodoneura, K. Schum. in Engl. Bot. Jahrb. xxxii. (1902) 134. 
Leafy and flowering stems distinet, the former reddish-tomentose, the 
latter fulvous-tomentose, aphyllous, branched from the base. Leaves tomen- 
tose on both surfaces, in а dried state reddish-brown on the upper surface. 
Stipules about 1 cm. long. Disce pilose on the inner surface. Stamens 23-26, 
Fruits 2:5-3 em. in diameter including the bristles. 
Angola: Benguella; near Huilla, Antunes, 50! 
Schumann’s description of T. rhodoneura is inaccurate in several parti- 
culars : the dise does not consist of broad ovate scales, but forms an undulate 
ring; the petals are not glabrous below ; and the under surface of the fully 
developed leaves is buff-coloured.in а dried state, not red ; both surfaces are 
reddish, however, in a young state. 
There are two sheets of T. rhodoneura in the Berlin Herbarium: on the 
first all the flowering shoots are fulvous-tomentose, as described by Schu- 
mann ; the solitary flowering shoot on the second sheet, however, is brownish 
and only sparingly pubescent, just like Baum's specimen of T. geoides. Ш 
there has been no mixture of specimens and the indumentum really varies to 
this extent, it may be questioned whether T. rhodoneura is specifically distinct 
from T. geoïdes. It might perhaps be treated as a variety. 
14. T. iomalla, K. Schum. in Engl. Bot. Jahrb. xv. (1892) 132. 
Whole plant densely rusty-tomentose. Stems of one kind, bearing both 
leaves and inflorescence, 20-30 ст. long, 3-4 mm. in diameter at the base, 
flexuous, the inflorescence developed with, or after, the leaves. Leaves 
elliptic-oblong or ovate-lanceolate, acute at the apex, rounded at the base, 
3-6 сш. long, 1:5-2:5 ст. broad, serrate, pubescent or tomentose above, 
woolly-tomentose below. Stamens 30-54. 
Congo Free State: Mussumba, Pogge, 21! 
15. T. hirsuta, nob., sp. nov. 
Caules validiusculi, leviter flexuosi, 10-60 ст. longi, basi 2°5-45 mm. 
diametro, superne + hirsuti, inferne glabrescentes. Folia + anguste oblan- 
ceolata vel lanceolata, dentato-apieulata, in basin angustata, 5-10 em. longa, 
0:5-2 em. lata, acutiuscule serrata, pilis stellatis et simplicibus hirsuta, 
precipue in innovationibus. Inflorescentia 4-10 em. longa, fulvo-tomentosa. 
Sepala 7:5-10 mm. longa, 15-275 mm. lata, extra aureo-tomentosa, intus 
venis 5-7 distinctis, cornu 0°3-0°5 mm. longo. Petala obovata, apice rotun-
