This is very near to B. decrescens, and also to B. Novae Hol- 
landice ; but it seems to differ from both in its shorter leaves, with 
the apices incurved and indistinctly dentate.

The specimens differ slightly from West Indian and tropical 
American in having the points of the segments of the leaf a little 
more acute. It is a very small species of a dull brownish colour, 
having its leaves inserted directly across the stem, and with their 
finger-like segments directed towards its apex.

Very much like L. Icevifolia, from New Zealand, but more 
pellucid. It also resembles L. reptans, but the areolation of the 
leaves is much more minute.
