          Edinburgh - April 4. 1825.

My dear sir,

I wrote and sent off my last 
packet in such haste that I found I had
omitted several of the crypts you had requested
my communications of. They are: 
"Hypn. [Hypnum] abietinum" is Hypn. proliferum. 
"Hypn. elegantulum" I think I mentioned but am
not sure I can make anything else of it. 
Tho' Hawkin's figure is not characteristic. 
Have you a capsule you could give me 
of it?

No. 20. Herb. Mad. is Polypodrium aureum. 
No. 11. D--D is Vittaria lineata
No. 2 D--D is a small variety? of Jung. [Jungermannia] microphylla. Hook. [William Jackson Hooker] illus. Ea. + .80
No. 3 D--D is Jung. spinulosa (Hook. Jung. [British Jungermanniae] +.14).

The packet marked Hypn.  Boschii & Leskea congesta 
contains 2 species. The larger one is Leskea pungens
The smaller one an undescribed Hookeria as
far as can be ascertained wihout fruit. I
call it H. capillaris. I have it also from Jamaica.

No. 1. Herb. Mad. is Jung. juniperoidea
Leskea albicans is Hookeria abicans, Hook. & Grey. in
Journal of Science v. 2. p. 230.

No. 22. Herb. Mad. Pistia stratiotes - a curious plant of
the nat. ord. [?]. I have received it from
the East Indies.

"Bartramia stricta" is certainly a dicranum and
of the group of which D. flexuosum is the
type. Without fruits nothing can be done 
with this.
