184 BOTANICAL INFORMATION. 
“In both the species examined, the stigmatic tissue appeared 
to be composed of very loosely cohering long cylindrical 
tubes, (not hexagonal) and instead of being more dense and 
coloured, it was pellucid and colourless.”

In directing my attention to the different forms of Cuscula 
growing in this vicinity, I was surprised to find several dis- 
tinct species, and a remarkable allied genus; while only a 
single species (C. Americana) is noticed in botanical works. — 
Having been induced to examine particularly both the kinds 
indigenous to this neighbourhood, and the specimens with 
which my correspondents in different parts of the country 
have favoured me, I offer the results of my investigations t0 
the public, with the view of directing the attention of Bota- 
nists, through our wide-spread country, to the subject ; 
trusting that this neglected tribe of plants may thereby be 
farther elucidated.

gressing in the United States of America, We trust we may now COn- 
sider that it has a firm footing in the “far West ;? for in Dr. Engelmann, 
now resident there, author of the memoirs from which the following = 
tracts are made, we discover a tact for observation, and a method of det 
cribing plants which would do credit to an inhabitant of the most 
civilized and scientific cities in Europe.—Ep, m
