So very thickly are the leaves and stipules crowded upon the
stems of this plant, that it is not without great difficulty that
their real structure is discoverable. It differs in many particulars
from any species hitherto described, but comes nearest to one
figured in the next plate from the Isle de Bourbon, and will probably
rank in the same division with J . trilolata. I have already
noticed as being squamose, the stems of another Jungermannia
(J . lamellala), though they are not so much so as in the present
plant.
