Cor. 3-, 4-, 5-petalled. Stam. 6,8,10. Styl.0. Stigma 3-lobed. 
Caps. 3-valved, 1-seeded. Seed arilled*." And it is further 
remarked concerning that generic description, that ** the cap- 
sule is 2-, 3-, 4-, or 5-seeded; and that the genus differs from 
Amyris only in the sessile stigma and arilled seed *."' 
Yet Willdenow, whose remark it is, has annexed to Amyris 
all the Icicas of Aublet, in every one of which the seeds are en- 
veloped in proper arilliform pulp ; and the style is so obscure in 
those, as in several other species referred to Amyris, (particularly 
A. polygama, A.pentaphylla, A. acuminata, and A. nana, Roxb.), 
that the stigma may well be deemed sessile in divers plants of 
both genera. 
The rest of the characters are not less indeterminate. Amyris 
polygama, as the name imports, has unisexual flowers. "This in- 
deed has been transferred to another genus (Schinus dependens of 
Ortega). But Amyris Kataf of Forskal appears also to be poly- 
gamous ; and so do A. acuminata and . of Roxburgh. 
While several Burseras exhibit no Mere blossoms. „Amyris 
Zeylanica is described as hexandrous: and A. decandra, as the 
specific name indicates, presents decandrous flowers; and so 
does another which I shall describe, and which I take to belong 
to the same family with the Amyrides, or at least with those of 
Roxburgh. More than one of the plants which have been re- 
ferred to this genus are variable, like Bursera gummifera, in the 
number of stamina and their Sonn dios PIRE of. m" 
and calycine divisions. | 
The berry of Amyris varies as ubi in presen of the num- 
ber of mature seeds contained in it, as the capsule of Bursera. 
Nor is the distinction of the pericarp, implied by those names, 
well founded in this instance. They are alike coriaceous and
