Dr. Smith has given it as his opinion, that from the disposition 
of leaves in New Holland plants no conclusion can safely be 
drawn as to their genera. "This remark however appears to 
me only applicable to certain families, or rather genera; for in 
many tribes the plants of that country are altogether as constant 
in their leaves as in any other part of the world. In proof of 
this, it may be sufficient to mention the order Rubiacex; and 
there are many others in which I find nothing at all — 
in this respect. | 
As to Proteacex, it must be acknowledged that in Banksia 
both verticillated and scattered leaves occur; but the leaves 
constantly in tbrees in Lambertia seems to me a circumstance of 
even greater importance than the number of flowers in the in- 
volucrum; and the opposite leaves of S M EADE M 
at once both from Rhopala and Hakea. s | | 
Although the form and divisions of leaves in the order are va- 
riable in no common degree, yet there are certain genera, botli 
among those of Africa and New Holland, which the leaves even 
m these respects assist in indicating. Thus; in that genus to 
which I have applied the name of Protea (the Erodendrum of 
. Mr. Salisbury), and I believe also in my Leucadendron, there 
is no instance of a divided or toothed leaf; thus also the leaves 
of Spatalla are filiform and undivided, and those of Serruria fili- 
form and almost always pinnatifid. ''Pheir dichotomous divisions 
in Simsia and Franklandia are still more characteristic ; and their 
division and remarkable -GST aedi pita Acer Spi
