The doubt as to the genus of this plant arises because the specimen is in such a 

 state that I am not sure that the grain of pollen described may not have been a 

 stray grain.

Harsh glabrous shrubs. Leaves often prickly. Floivers showy, 

 spiked ; bract ovate ; prophylla (bracteoles) 2 or 0. Calyx 4-partite 

 nearly to the base ; 2 inner segments much narrower than the 2 outer,

 cated close to the base; anticous lip 3-lobed, nearly flat, blue or white; 

 the mid-lobe bifid. Stamens 4, subsimilar ; filaments glabrous. Anthers 

 1-celled, oblong, muticous, conspicuously fringed by white hairs ; pollen 

 ellipsoid, with 3 narrow longitudinal chinks. Ovary with 2 to 4 ovules in
