I think I do not err in referring the 8. montanus, as well as 
the S. glaucescens of H. B. K., to the 8. microphyllus of the same 
author. This latter is the first of the published names, and 
therefore has the right of priority. The authors, in describing 
their S. glaucescens, remark, “ Differt a praecedente (8. micro- 
phyllus) cui similliraus, presertim forma foliorum et magnitudine 
omnium partium.” ‘These differences described are trifling in- 
deed to what we find in our own common Snowberry ; and with 
regard to S. montanus, the remark in the Nov. Gen. et Sp. Am., 
“8. microphyllo proximus: vix distinctus, nisi foliis floribusque 
multo majoribus.”. The figures of the two species there given 
might, as far as any differences even of size are discernible, be 
taken from one and the same plant. It may be some confirma- 
tion of our present opinion to say, that numerous specimens in 
our Herbarium, from different parts of Mexico, exhibit only one 
species. 
Descr. A much-branching shrub, with twiggy, opposite, ob- 
scurely-angled dranches, copiously leafy. Leaves opposite, small, 
on very short petioles, generally exactly ovate and acute, penni- 
nerved, glaucous beneath; sometimes broad-ovate, occasionally 
obtuse, always quite entire. Flowers axillary, solitary, scarcely 
longer than the leaves, and pointing downwards, so as to be 
much concealed by the foliage. Bracteas two, small, ovate, at 
the base of the ovary. Calya-limb cup-shaped, five-toothed. 
Corolla tinged with pink, tubuloso-infundibuliform ; Zim more 
or less spreading, of five, broad, ovate segments: tube of the 
corolla hairy within. Filaments short, inserted a little below the 
sinuses of the lobes of the corolla. Anthers oblong, scarcely ex- 
serted. Style half the length of the corolla, swollen at the base. 
Stigma capitate, two-lobed, downy.

style :—magnijied.
