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 

 snort 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 

 were slender midrib covered with glutinous pubescence. The 

 panicle is nearly a foot in length, branching at the axil of 

 each flower j 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 \\ 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, 

 ^vested by the persistent calyx, is 2-valved, and in other 

 Aspects resembles that of the other species of this genus. 

 f he seeds are small, roundish, subangular, the hilum being 

 se en on a prominent beak that projects from the lower end 

 of the ventral face, the surface of the testa is divided into
