914 THE JOURNAL OF BOTANY 
presented within the range of C. wndulata 
e extreme forms are so distinct in the appearance of the leaves 
from typical angustata that they seem quite deserving of varietal 
rank, and I treat them therefore as such, while recognizing that 
it is quite impossible to define the variety in any terms which will 
€ a certain number of plants in that limbo which is so 
characteristic of Nature and so terribly inconvenient for the her- 
barium 
I should refer the following plants, at least, to the variety :— 
C. anaustara Brid. var. rHystopuynia (©. M.) mihi. Folia 
transversaliter rugoso-undulata, lamina dorso_ spinis preedita, 
limbo infra medium dentato, in parte superiore argutius spinoso, 
areolatio obscura.
