196 MONOGRAPH OF THE 
Albany, Indiana (on Silphium). The second variety, which 
may prove a distinct species, grows on Helianthus, in similar 
localities. 
Flowers always 5-partite; tube not exactly cylindrical, but 
a little wider at the mouth than at the base, rather obconical. 
Styles longer than in any of our Cuscute, and almost always 
unequal, and inserted on a distinct stylopodium, also the 
largest in the genus. Stigma capitate, a character common 
to all the American species. 
While the above was actually in type, we have the pleasure — 
to receive the following remarks from the Author, ina letter — — 
dated St. Louis, Feb. 12, 1843. 
* Since the Memoir in Silliman's Journal was printed, I 
have had occasion to examine a large collection of Texan — - 
Cuscute, and have investigated this neighbourhood again and 20 
again, and am now able to correct some important mistakes : 
in my paper, and to publish some new species of Cuscuta as — 
well as one of Lepidanche. These additions and corrections I es 
have sent to Silliman’s Journal, but am ignorant whether they. 
are likely to appear soon in that work, which, as you are aware; 
is the only American Journal, not edited by some Society. - 
I can hardly hope that the notice which you so kindly pro- 
mise to insert in the London Journal of Botany, should not - 
have appeared ere this can reach you ; still it may be as well 
to state those alterations, &c., which I find necessary tO 
make. But, in case you realize the hope so agreeably held out, - 
of lending me your collection of Cuscutine, for examination fur- 
ther changes will, of course, be needful. There is one thing - 
which I much regret the impossibility of rectifying, and that 
is the names, which I, at first, thought very appropriate;for the 
species ; being under the impression that each Cuscuta grows: 
more or less, upon the same or similar kinds of plants. But I 
am now convinced this is entirelya mistake, ample proof having | 
been given that theidentical same species often grows upon total- 
ly different plants, without the least variation in its characters - 
I should therefore have wished to change Cuscuta Cephalanth
