 long cylindric spike of staminodes. Perianth none. Ovary 1 -celled; 

 stigma subsessile. Ovule solitary, basal, erect, anatropous. Male 

 flowers of 4-8 anthers united into a truncate angular body ; anther- 

 cells opening by short terminal slits. Barren organs, both pistillodes 

 and staminodes, elongated in the direction of the axis, irregularly

A specimen, which was collected in the Island of Zanzibar by StuWmann, has been 

 referred by Engler (Pfl. Ost-Afr. C. 132) to this genus, but is stated to be in too 

 imperfect a condition to admit of its specific identification. The only other known 

 species '(for T. madagascariense, Engl., is the same as T. lindleyanum, Schott) is a 

 native of the Mascarene Islands.
