The above diagnosis, differing in some respects from that 
given by Prof. DeCandolle, is drawn from my own observation 
upon a tree that has been growing in Kew Gardens from the 
time of Aiton. The leaves are 4i-5i inehes long, 2-2| inehes 
broad, upon a petiole 6 lines in length. The peduncles are 
from 4-6 lines long. The ealyx here is distinctly articulated 
upon the peduncle, and is always glabrous, though its teeth and 
the peduncle are tomentose, while, I believe, in the American 
specimens the ealyx is wholly tomentose, as described in the 
‘ Prodromus the whole flower is indeed only half the size of 
those in specimens from the United States, so that we may infer 
that it constitutes perhaps a distinct variety. The petals here 
are 6 lines long and 4 lines broad, narrowing gradually to the 
base into a claw, and are quite glabrous ; in native specimens 
they are sparsely elothed on both sides with stellated hairs, and 
in the bud tomentose externally. The stamens are 4 lines 
long, the anthers 1 line, the cells linear, parallel, and separated 
by a distinet interval ; each filament is perfectly glabrous, 
tubularly hollow, sub-4-gonous, and marked by a nervure 
along its back ; the termination of this tube is fleshy, forming 
a roundish linear connective, upon which the anther- eells are 
dorsally adnate for their entire length. In the American spe- 
cimens the stamens are 6 lines long, the anther-cells being 
2 lines in length ; but then the filaments are much broader, con- 
sisting of a thin simple membrane with a central nervure, and 
they are sparsely stellately pilose ; those in the bud appear to 
adhere together by their margins for their whole length, but on
