dages, which form a continuance of the winged margins, being 
subulate, scarcely a line in length, and erect. The style is much 
longer than the stamens, equalling the length of the corolla, and is 
thickened towards the apex. The berry not yet ripe (as seen in 
the specimen quoted), is three lines in diameter, supported on 
the persistent membranaceous calyx. I regret that the seeds were 
not sufficiently matured to determine the form of the embryo.

losa, limbo versus apicem pubescente, breviter sinuato-5-lobo, 
lobis 3-angularibus, callosis, margine tomentosis, dentibus longis 
-interjectis ; staminibus inclusis, ineequalibus.—Bolivia. v. s. in 
herb. Lindley. (Bridges, anno 1846.) 
The spines in this species are one inch in length, the leaves 
(including a short petiole of two lines) are one inch long, and 
three lines broad; the peduncle is thickened at the apex, and five 
lines long; the calyx is one line and a half in length, and dia- 
meter; the corolla is an inch long, and its tube two lines in 
diameter, the stamens are included, two of them being rather 
longer than the others, the lower half of the filaments adhering by 
a central nerve from the base to nearly half the length of the tube 
of the corolla, the two free-winged margins of which are also ter- 
minated by long subulate teeth, a little more than a line long, as 
in both the former species, and in D. Lycioides, the anthers are 
also basi-fixed, and of a purplish colour : those of the two longer 
stamens are within the mouth of the corolla, the others a little 
below: the style is included, and of the length of the stamens. 
5. Dunalia ramiflora, (n. sp.) : fruticosa, obsolete spinosa, ramis 
striatis, glaberrimis ; foliis apice ramorum fasciculatis, aut ex 
axillis annotinis solitariis, vel geminis, oblongis, in petiolum elon- 
gatum caniculatum tenuem spathulatis, obtusiusculis, utringue | 
glabris, subtus pallidioribus, margine sub-revolutis, nervis flexuosis; 
floribus axillaribus, presertim in annotinis solitariis, rarius binis ;
