his original specimens, and the Wonsen plants are found to differ 
from the latter in the forking being less divaricate and in the 
absence of the dense proliferations from the branches.

The compact, sturdy little plant received is very distinct in

classifying Laurencias are so unsatisfactory that one ^reluctant 
to add more forms or varieties to the list, which is already of
