 and rugose seeds.

 sessile, elliptic, imbricate, hairy, 7 lin. long, 4 lin. broad. Flowers 

 solitary towards the apex of the stem. Calyx 12 -toothed. Corolla-tube 

 7 lin. long ; open corolla 4 lin. in diam. Anthers acute above, glabrous ;

An insufficiently known species, said to be allied to T. Fischeri. 



14. T. sericea, Burkill, Stems short, sericeous, more or less hidden 

 by the leaves, which are slightly longer than the internodes. Leaves 

 ovate or elliptic, sessile, acute above, subcordate or more or less 

 rounded below, clothed with silky hairs on both surfaces, 9 lin. long, 

 4-5 lin. wide. Flowers on short peduncles, which are 2-3 lin. long; 

 bracteoles closely resembling the leaves, more hairy outside, finely 

 hairy within. Calyx-teeth rather long. Corolla-tube J in. long, 

 rather narrow ; lobes 4 lin. long, apparently white. Anthers obtuse 

 above, the posterior pair with one spur below, the anterior with two 

 slender spurs one on each lobe ; the margins fringed with hairs. Stigma 

 2-lipped, the upper only slightly exceeding the lower, inrolled.

This species and the preceding may possibly prove to be the same ; but the 

 anthers of T. hreicefioides are described as acute above and glabrous, while those of 

 T. sericea are obtuse and fringed with hairs. T. atriplicifolia, Drcge, closely 

 resembles it in some of its forms. 



15. T. Tischeriy Engl. Hochgebirgsfl. Trop. Afr. dS7. Stem erect, 

 densely woolly. Leaves sessile, oblong, somewhat acute, densely woolly, 

 firm, 2 in. long, J in. broad. Flowers presumably stalked ; bracteoles 

 lanceolate, 7-8 lin. long, 5 lin. broad. Calyx-teeth lanceolate-subulate, 

 somewhat glandular-pilose. Corolla-tube 1 in. long. Anthers with a 

 spur on each lobe and long hairs on the margins. Stigma 2-lipped. 

 Capsule I in. long, densely pilose.

Described as closely reseml Hng T. angolensis, but of the section Euthunbergia. 

 The description is not sufficient to enable its exact position in the genus to be fixed 

 with certainty.
