The present curious plant belongs to the same division of the 
genus as J. dilatata and J. Tamarisci; like them having the lo- 
bule of the leaf or auricle terminated, at least on one of its seg- 
ments, by aclubshaped vesicle. Here indeed these appendages 
are not confined to the leaf, for there are two on the middle seg- 
ments of the stipule, and the whole underside of the plant has a 
most singular appearance from the number and regularity of the 
vesicles. The calyx, however, differs remarkably from J. dilatata, 
and the rest of its affinities, and more nearly resembles that of 
J. juniperina, being altogether covered by leaf-like scales.
