cross the stem transversely without the least tendency to decurrence. The apices of the leaves being a little incurved, 
and the leaves themselves subconnivent, give the plants a canaliculate appearance.—PrATE CLXXIX. Fig.2; l,a 
portion of the stem, with leaves and stipule :—magnified.

Sordide pallide fusca. Caulis bipollicaris, flaccidus. Folia explanata, margine dorsali apicem basinque versus 
dentibus subulatis spinoso-dentato, medio ssepe leviusculo, apice ut plurimum bispinoso, rarius unispinoso, margine 
ventrali undulato, dentibus latioribus. Amphigastria transverse oblonga vellatissime cordata, sinu brevi rotundato

hexagonis interealaribus nullis composita. Spice mascule breves, foliis ovatis acutis dentatis concavis, inter folia 
amphigastriaque omnino latentia. 
A remarkable species, possessing considerable resemblance to C. Billardieri in the general outline and dentation
