corolla, Though the names C. acutangula or C. Morettiana 
var. acutangula appear to have become generally adopted 
in collections, Feer has made it perfectly clear that they are 
only recent substitutes for the original name and must 
therefore be set aside. The plant from which the material 
for our figure was obtained is one purchased for the Kew 
collection in 1909 from Mr. H. Correvon, of Geneva, under 
the name proposed by Leresche and Levier. It forms a 
close prostrate tuft about 2 inches high and should be 
planted in a sheltered position in well-drained shingly soil. 
The flowers are produced in July ; unfortunately the species 
has not proved hardy at Kew.
