A monotyric genus native of South -Africa. 



The name is given in honour of ^-rs. ^. vander ^ijl, who has 

 very kindly sent to me specrmens of this and other novelties. This 

 genus is distinct in appearance, but more nearly allied to Ceroch- 

 lamys then to any other genus.

 ing clumps. Leaves opposite, in 1-3 pairs to a growth, incurved- 

 spreading, and eK received, 9-16 lines long, 4-6 lines broed and 

 3-4^ lines thick at the base, and 5-9 lines broad and 4-8 lines 

 thick near the apex, v;here the keel is dilated, clavately and often 

 obliquely trigonous, obtuse, not toothed, flat on the face and of- 

 ten on one of the sides, the other side being (or sometimes both

 cribed for the genus, when closed 3-4 lines in diameter, and scarce- 

 ly more v/hen expanded, as the valves separate but slightly and re- 

 main inflexed, vrith the openings between them only g-lf line^v/ide
