This species resembles T. Stuhlmannii, Engl., in habit, especially in the short 

 leafy axillary inflorescences, but it differs in the very small perianth.

lao^wer Guinea. Liow er Congo : Dolo, Schlectert 12810 ! 



A long wiry plant, leaves few, reduced to scales ; the flowers, with the relatively 

 long perianth-lobes and the anthers borne on long filaments, are similar to those of 

 T. Stuhlmannii, Engl.

 flexible, smooth. Leaves spreading, narrowly linear, apex cartilaginous,

This species very closely resembles 2^. «t^riea».9,Rendle, and it seems not unlikely 

 that with more complete material it may be found that T. ulugurense "annot be 

 maintained as a distinct species.
