Closely related to T. Stuhlmannii, but differs in its more bushy habit with more 

 delicate branches, in the ovate acuminate ciliate bracts and in the long linear- 

 elliptic perianth-segments. 



24. T. Stuhlmannii, Engl in Pfl. Ost-Afr. C. 168. Undershrub, 

 perennial; rhizome thick with numerous stout erect stems; stems 

 grooved, angular, 6 in. to a foot or more high, branching above ; branches 

 erect, simple, bearing numerous short dense axillary inflorescences. 

 Leaves few, reduced to ovate-lanceolate acute scales, about 1 lin. long, 

 sharply keeled. Flowers crowded on short compact leafy axillary 

 branches ; bracts and bracteoles ovate, acute, margins membranous, 

 glabrous or slightly fringed, sharply keeled, 1-1 J lin. long. Perianth

A specimen collected by Gossweiler, 2833, near the source of the rivulet 

 Campulua, Angola, resembles T. Stuhlmannii, Engl., but is a more wiry plant, with 

 long slender sparingly forked branches, and bracts smaller than those of T. Stuhl- 

 mannii. In the absence of flowers the species cannot be described. 



25. T. masukense, Baker in Kew Bulletin, 1910, 18G. Subshrub ; 

 stems slender, wiry, erect, glabrous, sulcate, winged below, about 1 ft. 

 high ; branches few, erect. Leaves reduced to subulate acute scales, 

 keeled, about J lin. long. Flowers borne on short compact leafy axillary 

 branches or on terminal spikes in the axils of bracts; bracts and bracteoles 

 equal in length, about 1 lin. long, narrowly ovate, acute, keeled, with 

 membranous slightly ciliate edges. Perianth about f lin. long ; lobes 

 I lin. long, ovate, subacute, hooded, glabrous. Anthers ^^ lin. long. 

 Style \ lin. long. Fruit globose, about J lin. in diam., with thin well- 

 marked ribs and distinct cross veins.
