          in the Cryptagamous Tribes — these being so little known are
doubly interesting. I thank you for several rarities in your
parcel. Schizaea pusilla is a charming little plant and is beyond

intermedia * the L. dentata of Willd.? Whose character is, Anthere bilocularis,

news of the day is a follows — Dawson Turner has finished 
his splended work on the Fuci & declines giving any arrangement
of them into new genera — a task that has been since ably
performed by [Hans Christian] Lyngbye a Swede. — Dr. Will Jackson Hooker has
finished his work on New Musci. 2 vols. Lt vel Ova. a beautiful
work standing at the head of its class — the same author
published a Muscologia Britannica 2 years ago which deserves
the highest praise (a plate of every species). He is also carrying on
that great work which Curtis began. The Fl [Flora] Loudineusis fol.

to be in [?] one vol & out in April next. [John] Lindley a young
botanist of London has just published an excellent Monographia
Rosarum with 19 Plates (colored). [Jakob] Sturm has just finished & published
an index to his Fl. [Flora] Deutchlands. (gr no.) 16 plates colored in each, duodecimal
