St Helena. — Endemic. Growing in barren places near, and south-east from the Gut 

 in Deadwood — Burchdl, 59. 



We have only seen one plant of this grass, which we have ventured to describe as 

 new, because we have not been able to identify it with any known species of the genus, 

 though it is closely allied to Demazeria acutiflora (Brizopyrum acutiflorum, Nees). The 

 latter is a native of South Africa, and apparently very rare, for we have only seen speci- 

 mens collected by Drege in Piquetberg, on the west coast, about one hundred miles north 

 of Cape Town. It differs from our plant in its erect habit in having usually several 

 inflorescences on the same culm, in its very much more acuminate glumes, of which the 

 outer want the prominent ribs. Further, the almost aristate flowering glume is copiously 

 bearded on the keel as well as on the margins (PL LI. figs. 9-12). It is possible that the 

 St Helena plant may be a stray introduction from the Cape of a species which is rare and 

 local there. At the same time it was collected in a remote part of the island, where one 

 would little expect to find a solitary introduced plant.
