in consequence of which several corrections in the new combinations 
have to be made. 
Kellogg in founding the genus Marah in Proc. Calif. Acad. i 
(1853), 37, considered the word Marah to be masculine and he has 
therefore been followed. Greene , however, has used Marah as a 
feminine word. In the following corrections of ihe new combinations 
the specific names are retained in the masculin

A ee triquetrum, L., w is "very common on the Algerian

This Allium is called ‘ Bibrous’ or ‘ Bibraz’ by the natives, : a 
name by which the leek is also known. The plants are collected in

After this first trial I attempted the cultivation of the plant 
from seed at the Botanic Siation, but experience quickly showed that
