This species approaches most to T. spinosa, Willd. (not Koxburgh,) or Batis spinosa, Roxb., but in that 
there are four stamens, thorns on the branches, roundish capituli of male flowers, and, from the receptacle of 
the female flowers enlarging and becoming fleshy, the fruit appears to remain enclosed, and never to be ex- 
serted. There can be no doubt but all the species of Tropins have a true monophyllous perianth enclosing 
the ovary, similar to what we have recognized. — We shall here add the following abridged synopsis of all the 
species which have been hitherto described : —

T. laurifolia of Willdenow constitutes two species of Styloceras, S. Kunihianum, Adr. de Juss., and S. 
laurifolium, Kunth, and forms a genus among the Euphorbiacem. Perhaps T. aculeata, Roth, may be- 
long to the Flacourtianece. We do not know T.? Heyneana, Wall. List of E. I. Plants, n. 4642. T. cor- 
data, Poir., or Streblus cordatus. Lour,, from Canton, is certainly not of this genus, but rather a Brous- 
sonetia.

The equality or inequality of the base of the leaf, affords, we believe, no character, both kinds sometimes 
appearing on the same branch. We have three forms before us from China; one in which the leaves are 
whitish on the underside, at least when young, and their length about thrice the breadth; a second has the
