A remarkable monotypic genus of which we have unfortunately incomplete 

 specimens. It falls into the Eujusticiece section of the tribe Justiciece, amongst 

 the genera with two-celled anthers having equal and muticous loculi. Its most 

 prominent features are its habit, for it exhibits long straggling branches some- 

 what arcuate and striate with long internodes possessing a large pith contracted 

 at the nodes, its long spicate inflorescence, and its curiously-bent corolla, with 

 a long ligulate upper lip, external in aestivation, and a broad trifid lower lip. 



In the set of genera with which it is associated there is no old world genus 

 with which it has a close affinity. The tropical African Himantochilus is the 

 nearest of them, but is readily distinguished by its inflorescence and corolla. 

 Possibly its nearest ally is the Brasilian Schaueria which presents the same 

 habit and striate stems with a large pith, and has also long somewhat similar 

 spicate inflorescences ; but it is readily separated by its calyx, corolla, bracts, and 

 other characters.
