greenhouse in the months of September and October. Of 
all the species with which we are acquainted (and we pos- 
sess yet some undescribed ones gathered between Buenos 
Ayres and Mendoza) the present exhibits the longest tube 
to the flower, which appears the more remarkable from its 
arising from so broad a calyx. In the form of the leaves, 
the species comes nearest to the original N. repens, FI. 
Per., but the habit and the form of the calyx are extremely 
different in the two... 
Descr. The stems are decumbent and branched, scarcely 
woody, yet the plant promises to be of perennial duration, 
diffusely branched ; the branches pubescenti-glandular, as 
is the whole plant except the corolla. Leaves sometimes 
opposite, sometimes alternate, broadly obovate, entire, 
rather obtuse at the point, at the base tapering into a short 
footstalk. Peduncle \ateral upon the stem, not arising from 
an axil, short, single-flowered. Calyx large, campanulate, 
with five obovate, leafy lobes, each marked with a nerve in 
the centre. Corolla with a very slender tube, almost three 
inches long, yellowish, suddenly expanded at the summit 
into a rather large, broadly campanulate, five-lobed, white 
lunb, its base alone yellow. Stamens five, springing from 
the mouth of the tube, curved upwards, two a little longer 
than the rest, having their anthers lodged within the trans- 
verse, curved, green stigma. Our wild specimens differ 
In no respect from the cultivated ones, except in being 
smaller.
