There is very little tenable ground for maintaining this 
genus, as hitherto constituted, distinct from Lycium, there 
being hardly any single character that is not equally common 
to both of them, excepting the hairy tuft at the base of the 
filaments in the one, (and that is a very inconstant feature), 
and the numerous fascicles of flowers in the cicatrices of the 
fallen leaves in the other. An important distinction will, how- 
ever, be found to exist in the estivation of the corolla. We 
have the respectable authority of Schlechtendahl and Schott, 
which has been acceded to by all succeeding botanists, that 
Acnistus possesses an imbricate estivation. I cannot affirm 
this statement, for in the Brazilian species upon which Schott 
founded this genus, the lobes of the corolla unquestionably 
adhere by their tomentous margins, which are mutually and 
slightly turned in, a mode of estivation observed in many 
arborescent species of Solanum, and very different from that 
of true Lycium, where the lobes of the corolla offer an imbri- 
cate or quincuncial zstivation. It therefore seems advisable 
to unite with Acnistus, several species hitherto combined with 
Lycium, forming part of the section called Anisodontia by 
G. Don, and Lyciothamnos by Endlicher ; these mostly con- 
sist of spineless trees or shrubs, with large leaves, having 
flowers in umbellate fascicles, and I propose to confine within 
the limit of Lycium proper, those shrubs, mostly with small fas- 
ciculate leaves, whose branchlets terminate in spines, or have 
a tendency to do so, that have only 1 or 2 flowers in each axil, 
and with elements corresponding to the old generic character 
exhibited by Gartner (de fructu 2.242), with the addition of 
the before mentioned estivation.* 
* The remaining species of Zycium in the section above alluded to, ap- 
pear to me again distinct, approaching very closely to Dunalia, but as 
their filaments want the lateral appendages peculiar to that genus, I pro- 
pose uniting them under the name of Cuznesrues, derived from wa 
dehisco, es9n¢ vestis; on account of its tubular calyx splitting by the 
growth of the fruit. This genus will comprise 5 species described by Prof,
