Dear Dr.

Letter came from you soon after I despatched
one this morning to you.
& your parcel came just now. Thanks
for Amoreuxia. That is it! I have got
some fragments of it in Cruthers [crossed out: coll.] Mexican coll.
from Sonora alta. & was wondering what family
it could be.

188. Fendl. = Spiraea [?] Nutt. which Hook.
has taken up as a species in Pl. Geyer - & with good reason
I should think. No doubt it is your S. discolor, in
Am. Lye. But is it really Pursh's, who has
no S. anafolia, & says "folus ovatis lobatis" while these
are obovatis [cuneiformibus?], indivisis.

I remember that
you have a leaf from Pursh's specimen. I would ask
you to compare & see if his may not be a more downy var.
of true anafolia, like the spec. from Calif. Douglas,
which is S. anafolia & not the other. I add a fragment
of Pl. [Fendl?]. The panicle is small & contracted.

.460.1846 Frem. = Puntia [?]
[?] ... [?]

No. 198, Fendler. Will you compare it with P. [?],
Dougl. It apparently dont well agree with any other
forms (the stem is nearly naked; the ext. calxy - segments
pretty large, etc.

" 199. Ditto. Compare it with [P?] [?] var. strigosa
I suspect this is new.

What is the P. gossypina, Nutt., which Hook in Geyer takes
up as a species.
