Engelmann, George Jan. 8, 1842 [2] (seq. 31)

though the extreme forms are certainly very distinct.

As at present advised, I would refer your specimen
from western New York on Decodon verticillatus to {Cuscuta} saururi,
and
not Carinata — and also Mr Carey's specimen from
Georgia — The C. carinata, tetrameris is certainly very
singular, and may prove on further investigation a
distinct species. C. cephalanthi is generally 4 androus
I have again examined at least 10 specimens and
a hundred flowers. — Finally I had occasion to
examine a Cuscuta from Mt. Sinai, and that agrees
with the other European ones in the filiform stigma!

I request you therefore to make if it is still time,
the following changes:

In the Conspectus of the Species
instead of a. Europeans say: a. Inhabitants of the old world
2. C. europaea etc
3. C. epithymum etc segments of calyx and corolla acuminate, shorter than the tube of the corolla
4. C. arabica Fresen segments of calyx and corolla acute,
illegible Europe Mount Sinai.
longer than tube of corolla
5. C. epilinum etc alter numbers 6. 7 etc.
# five parted on pentamerous.
7. C. chilensis
## four parted
8. C. cephalanthi
9. C. coryli :
10. C. carinata calyx carinate, segments of corolla obtuse
half as long as tube. N. America
11. C. saururi segments of corlla obtuse equal to tube
Southern and Western States
14. C. polygonorum
In the description of the Species you please mark the following
changes.
C. cephalanthi flowers mostly 4 parted
C. coryli grows in hazel thickets in Praries and barrens
Illinois & Missouri
C. carinata speaking of the locality say: Var. & appears to be
the southern and western form — strike out : [On Deocodon Dr Gray]
add: Western Pennsylvania (Dr. Short) — — Georgia — strike out:
(J. Carey) and add: (Dr Boykin in herb Short)

at the end of the Article strike out the last paragraph beginning:
"the specimens from Georgia — — to refer it to this species

C. saururi add to the locality: this fall, Sept. 1841: Sub-
-sequently I had occasion to examine specimens
from Western New York, on Decodon (Dr A Gray)
from Western Pennsylvania (Dr Short)
from Kentucky on Polygonorum (Dr Short), from Alabama
(Dr Prout) and from Georgia (J. Carey).
———
It may be that carinata & Saururi must be united
and constitute the true Gronovian C. americana
but so far I believe I can distinguish them by the
Carinata has smaller flower, fruit only half as large, round
lobes of calyx, deeply campanulate tube and short round lobes
of corolla.

Saururi has larger more open flowers, large fruit,
oblong lobes of calyx and of corolla which are equal
to tube. — The scales appear to be not very
constant. —

Nothing botanical else at present.
Can you obtain a copy of Elliot's flora for me?

You will also do me a favour by sending me
the last edition of Eaton's manual; I have
sent my copy to Texas, and must have some
thing else till your flora is finished —

Any thing you have for me you can
send by Mr Poppe, Pearlstreet 92, as I
understand that he sends a box of goods
on here immediately — but if you do, you
must ask him to send it right away
with that box — annother opportunity
will soon offer by Mr Kimm — who
leaves here in the course of this month
and shall take things on to you

Yours Truly
