development of the veins of leaves. The first change is the 
lining out of the new veins, at least on the circumference from 
extension of those more developed'; this lining out depends 
apparently rather on a want of opacity or cessation of action, 
than on any distinct production. 
Then into these, lines of a more diaphanous nature pass 
the. vessels, it may be inferred by extension, although 
some vessels are seen lined out and barred without any 
apparent connection with the more developed ones; this 
transparency of the reticulations is at first slight, afterwards 
just when the vessels may appear it is so distinct as to seem 
as though formed by a proper canal. 
The parenchyma has a mucilagino-cellular appearance, and 
the cells contain plenty of chlorophyll. 
The margin is thick mucilagino-cartilaginous looking, of 2, 
3 series of perpendicular cells, and is thickest over the teeth. 
In a very young state the flower is axillary to the left hand 
stipule, the cirrhus a short point, evidently axillary to the 
leaf. : 
Although the cells even of the disc are well marked out 
under 5; * M., yet they do not present a hyaline appear- 
ance; the appearance is that of mucilage. 
Stipule here belong to the leaves, because the leaves are 
produced first. 
The central lobe first entire, then two minute prominences ; 
at this state an entire broad ae dise occurs in the 
axilla! 
Then the disc becomes oblique and sub-bilobed, the lobe 
next the leaf opaque, becomes a cirrhus, the outer lobe the 
lowermost and largest bractea, the part between is developed 
into the flower. 
Hence the cirrhus is “one belonging to the inflores- 
cence. 
The cirrhus is entirely skilled
