Has. On saline clayey soils, within the high calcareous hills of the 
Upper Colorado. n. 100. 
This has the ramification nearly of Æ. angulosum, and the leaves are 
in like manner from two to four together at each branching, but, instead 
. Of proceeding from the inside of the stipules or bracts, they are the 
foliaceous development of the bracts themselves. The divisions of the 
involucre are very unequal and free almost to the base, but not entirely 
so, as supposed by Nuttall, at least in our specimens; the flowers are 
precisely those of Zriogonum, the fruit has its angles remarkably pro- 
minent and acute, but that cireumstance appears to be hardly sufficient 
to found a genus upon*. 
13. Eriogonum divaricatum, sp. n.; annuum, humile, pubescens, ra- 
mis divaricatis dichotomis, foliis petiolatis ovatis crassiusculis, radi- 
calibus rosulatis, ramealibus ad dichotomias intra bracteas geminis 
fasciculatisve, involucris alaribus sessilibus ramulosve breves termi- 
nantibus minutis hemisphzricis profunde 5-fidis, perigonii hirtelli

Herba 3-4-pollicaris, a basi sæpe multicaulis. Folia radicalia 3-5 
lin. longa, obtusa, basi angustata, petiolo subsemipollicari. Bracteæ

similia, gradatim minora. Jnvolucra vix lineam longa. Perigonia

On the Botanical Labours of the VELLOSIAN SOCIETY of Rio JANEIRO, 
and of its President Dr. ALLEMÃO; by GEORGE BENTHAM, EsQ.  — 
Some account of the Proceedings of this Society, apparently pub- 
lished at Rio Janeiro, under the name of “ Trabalhos da Sociedade Vello- 
siana," in a work entitled * Bibliotheca Guanabarensis, having been 
lent to me by my friend Mr. Miers, together with some detached papers 
Linnean Transactions, the num- 
to be six; it is however more 
fo six or even seven, and is 
* In Mr. Bentham’s Paper on Eriogonee in the 
ber of teeth of the involucre in Eriogonums is stated 
frequently five, but varies often in the same specimen 
sometimes reduced to four or three.
