C.G. Pringle, no. 3756 (type, in hb. Gray). ‘This was distributed as 
C. scorzonerifolia, “a narrow-bracted form.” It seems quite distinct, — 
peculiar in the group in the erect divisions of the lower lip which some-

appearance like many of the Chenopodiaceae. The lower part of the 
stem is marked by bunches of leaf-scales resembling tubercles like those 
on C. communis and C. arvensis. The flowers are ochroleucous.
