PAVETTA sTIPULOPALLIUM K. Schum. No. 1350. Here the 
stylar-head is long and shaped like an attenuated Indian club. 
There is a small cleft at its serarareeg The outer surface bears

grows out to a wide exsertion. It acts as hee archon Later 
widely separated. Here the true stigmatic surface is to be found. 
It would seem as though the Lge of pollen upon the stylar- 
brush inhibited development in the stigma, the stigmatic surface 
being seen best developed saliben the stylar-brushes were least 
encumbered. 
An interesting point is the mutual adaptation shown between 
the very long sessile anthers and the long brush of the stylar-head. 
In all three of the foregoing examples introrse dehiscence of the 
anthers is, as might be supposed, a tributary accompaniment. 
No. 1351. The appearance of the bark of this 
species is nigh FR rthy. It cracks in a series of regularly disposed 
horizontal rings, averaging Petit half to three- noah of an inch 
cape in medium-size the younger branches the 
ings are more closely set, in the older wood they are wider apart 
ana less well-defined. The attendant vertical cracks are not so 
straight, and ithe they. lie, upon an average, from a quarter to 
half an inch a The two sets of cracks divide the surface 
up into rude De ilontati giving a led effect sufficiently 
characteristic to enable the observer to "identity the tree by the 
bark alone
