This plant which I found in Chile in 1821, bears much 
analogy to N. acuminata, Grah. and is distinguished for the 
very singular elongation of the midrib of the leaves, and of 
the nervures of the calyx and corolla. I do not remember 
the size of the radicular leaves, but those of the stem measure 
9 inches, including 1 inch for the petiole, 5 inches for the 
blade, and 3 inches for its cirrhiform apical extension : they 
are 9 lines broad with a very undulatory margin, and are 
covered.on both sides (like the remainder of the plant) with 
short glutinous articulated pubescence, the upper leaves 
become gradually shorter, narrower and linearly lanceolate 
with reflected margins, while the floral leaves or bracts are 
14 lines long, quite linear and terete, being reduced to a 
mere slender midrib covered with glutinous pubescence. The 
panicle is nearly a foot in length, branching at the axil of 
each flower ; each pedicel is about 4 lines long; the somewhat 
campanular tube of the calyx is 2 lines, and the mucronate 
teeth are from 2 to 3 lines in length; the corolla is nearly 
2 inches long, and barely 3 lines diameter in the mouth, the* 
border is narrow, with 5 short obtuse teeth, having slender 
cuspidate nerval extensions of 14 line in length; one of the 
stamens is shorter than the other 4, which are almost in didy- 
namous pairs, the filaments are slender and glabrous, arising 
from a little above the base of the tube: the ovarium is gla- 
brous, the style slender, and the stigma has the peculiar 
form of this genus, the capsule is about 5 lines in length, 
invested by the persistent calyx, is 2-valved, and in other 
respects resembles that of the other species of this genus. 
The seeds are small, roundish, subangular, the hilum being 
seen on a prominent beak that projects from the lower end 
of the ventral face, the surface of the testa is divided into
