I found this plant in 1825, at Arecife, 120 miles westward 
of Buenos Ayres; it seems to correspond with the Jaborosa 
runcinata of Link and Otto; but as Sir Wm. Hooker justly 
observes, it has no upright stem, as figured by these authors, 
for the leaves and peduncles proceed at once from the collar 
at the summit of the root. The plant seems to propagate 
itself by running suckers which at intervals strike root into 
the ground, where they form new plants. The leaves vary 
from 2 to 3 inches in length, and 14 to 2 in. in breadth; the 
petioles being about an inch, and the peduncles about 14 in. 
long; at times they are somewhat larger. The calyx is sub- 
fleshy, with 5 equal, acute, erect, persistent lobes. The co- 
rolla is campanular, somewhat contracted in the mouth, the 
border being 5-partite, with oblong acuminate lobes, and a 
plicate estivation ; it is of a yellowish white colour, fleshy, 
quite glabrous outside, and hairy at base within. The stamens 
have very short filaments inserted below the mouth, expand- 
ing into a thick fleshy connective, to which the 2-celled anther, 
bursting longitudinally, is dorsally attached. The ovarium is 
green, globular, half immersed in the fleshy torus ; the style 
is simple, white, slightly curved, and is distinctly tubular at 
the summit to some depth; the stigma is clavate, and indis- 
tinctly 2-lobed. I met with no seed sufficiently advanced to 
show any indication of the embryo, the character of which I 
have stated on the authority of Endlicher.*
