A careful re-examination of this-tribe daring the past season, j 
as well as the increased opportunity of examining specimens from 
different parts of North America, have discovered some errors, and 
made some corrections and additions necessary, which I should, 
indeed, prefer to withhold for the present, and subject tq the test 
m of another season’s study, if it were not important to correct such 
~ errors as soon as possible. A fuller description of the new spe- 
. cies, with figures, I defer to another time. 
I am now convinced, that, although many Cuscutee prefer some 
plants to others, yet there is rip constancy in this respect, but the 
same species often grows upon a great variety of widely different 
> plants. I did wrong, therefore, to name them from the genera 
■ upon which they grew; and I should much prefer to seethe 
names of C. Cephalanthi changed into C. tenuijlora, C. Coryli 
into C.incurva , C . Saururi into C. umbrosa , Beyr. ? C. Poly go- 
norum into C. chlorocarpa, and Lepidanche pompositarum into 
L\ squareosa, if they had not yet been published. 
I. CUSCUTA, 
1. Cuscuta Cephalanthi. —Mostly 4-parted; frequently only 
3-par ted. 
2. Cuscuta Coryli. —Found in man^ places near St. Louis, on 
Hazel, Willow, Desmodium, Teucrium, Solidago, etc. The long 
styles observed income dried specimens of this as well as other 
species, are the *nsequence of a continued vegetation in the 
plant-press! The variety §. must therefore be stricken out. 
Flowers frequently 5-parted. 
3. Cuscuta vulgiyaga. —Certainly the most common species. 
The stylopodium is very remarkable in the living specimens 
which I have examined; and the capsule is oval, even a little 
pointed, less globose than any other of our Cuscutsebut l am 
not prepared to say that this is the case with all varieties of this 
* The characters of the new species, &c. here described, have been%)ublished in \ 
the London Journal of Botany for April, 1843, 
nograph, there reproduced.— Eds. ,
