Mr. J. Miers on the genus Juanulloa. 187 
parallel margins, which are slightly connivent ; the tube of the 
corolla is about 3 inecies in length, contracted at base for the 
length of 14 inch to scarcely more than 13 line broad, and swell- 
ing above to a diameter of half an inch; the lobes of the border 
are about half an inch in length and 4 or 5 lines in breadth, 
somewhat obtuse and patent ; the stamens appear to originate in 
the contraction of the tube, with the anthers considerably below 
the mouth of the border; the corolla is of much thinner texture 
than that of MW. coccinea: in the form of its berry and enveloping 
calyx, the arrangement, size, and shape of its seeds, its lax testa, 
very thin albumen, and form of its embryo, it quite agrees with 
the former species. 
JUANULLOA. 
This little-known genus of the ‘ Flora Peruviana’ was scarcely 
understood by the botanists of our time, until the very interesting 
account and excellent figure of a plant raised from seed in the 
Botanic Gardens of Kew was lately published by Sir Wm. Hooker. 
This proves to be a very different species from that figured by 
Ruiz and Pavon, and although generically identical with the 
Laureria mexicana of Schlechtendal, is again specifically distinct 
from it. The genus approaches Solandra in its climbing habit, 
large coriaceous leaves, and in the general structure of its flower 
and fruit, agreeing with it also im having a calyx consisting of five 
distinct sepals, conniving by their edges into an acutely pen- 
tangular tube, but here they subsequently become quite separate ; 
it is also dissimilar in the cylindrical form of its corolla, with a 
small border of five rounded patent lobes, and with included 
stamens. It likewise approaches Marckea in the structure of its 
calyx, in which respect it resembles Nicandra and Cliocarpus, 
with which latter genus it also agrees, in having stellate tomen- 
tum. I have been able to complete from different sources the 
following amended generic character :—
