Owing to the close packing of the glumes on the rhsicliilla, the Pjjikelets of this 

 species are very unlike those of C. dichromencBformis ; but the two species agree in a 

 great number of minute points and may prove to be but one.

This striking species is at once recognised by tlie umbel-rays being longer than 

 the stems. In cultivation at Kew, the umbel-rays trail all round the plant.
