I will conclude with a notice of another species which 
was sent me from the Liverpool docks by Mr. Griffiths, 
whose structure is so puzzling that I know not whether to 
call it dicotyledonous or monocotyledonous. It consists of 
a central spongy mass of woody tissue apparently without 
medullary sheath, pith, or medullary rays, and arranged in 
the form of a pentagon formed of semicircular lobes, the 
whole being surrounded with what appears to be liber which 
has shrunk away from the very thick and hard external 
bark, so as to leave the woody core isolated within it. The 
core consists of woody fibres, but half its area is taken up 
with wide-mouthed vessels. 
I may add that the whole of these lianas furnish beautiful 
objects for the microscope. 
Mr. F orrest suggested that useful dyes might be obtained 
from the plants described by Mr. Bailey. 
In reply to a question from the Rev. Brooke Herford, Mr. 
Bailey stated that owing to a difference in the structure 
and general appearance of some of the stems in his posses- 
sion he had been led to suspect that they were aerial roots 
of some of the plants he had exhibited and described.
