Mr. J. Miers on the genus Cacabus. 255 
with a callous discoid process, resulting from the hardening of its 
epigynous gland. 
2. Cacabus Nolanoides (n. sp.) ;—herbaceus, molliter villosus, caule 
striato, dichotome ramoso ; foliis geminis, altero multo minori, 
ovatis, crassiusculis, undulato- vix sinuato-angulosis, margine 
ciliatis, basi mzequalibus, utrinque glabris, mferne nervis pilo- 
sulis, petiolo late dilatato, ciliato, folu longitudine ; floribus 
solitaris, lateraliter extra-axillaribus, pedunculo florifero erecto, 
fructifero retlexo, corolla czerulea : calyce inflato, membranaceo, 
10-nervi, reticulatim picto.—Peruvia, v. s. in herb. varius 
(Mathews, no. 839, sub nomine Nolane spathulata). 
The leaves of this species are nearly oval, 4 inches long, 2+ 
inches broad, upon a fleshy dilated petiole, with winged ciliate 
margins, 21 inches long and nearly 2 lines broad, subamplexicaul 
at base. The peduncle im flower is 14 inch long, the calyx is 
6 lines long and 4 lines broad, the corolla is 14 inch long, and 
11 inch across its somewhat expanded and nearly entire border, 
The peduncle in fruit is reflexed, 14 inch long ; the enlarged calyx 
is 8 lines long and 7 lines broad, the inclosed berry measuring 
3 lines in diameter. This plant, which so greatly resembles the 
figure of Nolana spathulata in the ‘ Flora Peruviana,’ differs from 
it in the size of its leaves, the length of the petiole, the shape of 
the calyx, the size of its corolla, its more entire, not deeply-lobed 
border, the shape of its stigma, its vesicular calyx, not fleshy and 
subsequently bipartite, and finally by the very different structure 
of its fruit. It agrees in many respects however with the de- 
scription of the text*. 
3. Cacabus? inflatus. Nolana inflata, R. & P. Flor. Perw. u. 
p- 7. tab. 112. fig. a;—herbaceus, pedalis, prostratus, annuus, 
foliis radicalibus confertis, oblongis, in petiolum longum imo 
decurrentibus, caulinis geminatis, ovatis, subobtusis, basi m- 
eequalibus, breviter petiolatis, petiolo dilatato ; floribus gemiis, 
ex axillis lateraliter ortis, corolla speciosissima, albo-violacea ; 
fructu calyce striato, ventricoso, incluso.—Peruvia (in arenosis 
Prov. Arequipe). 
From its inflated calyx, there is every reason to conclude that 
this plant belongs to this genus, rather than to Nolana. It was 
not seen by Ruiz and Pavon, being only known to them from the 
sketch sent them by their draughtsman Tafalla; the fruit is not 
described as consisting of distinct carpels, but as  semina 4-locu- 
laria,” which may have been construed from “fructus 4-locularis,” 
which the fruit of Cacabus almost appears to be, from its project- 
ing placente. It has a prostrate habit, is about a foot long, its

of the ‘ Ilust. South Amer, Plants.’
