WorcestersuirE Prantrs.—I am desirous of forming a Her 
orks exclusively of Worcestershire plants, specimens of oth 
mon and rare species, with their v a being wanted from 
the four botanical districts (see ‘ The ee y of Worcestershire,’ by 
Mr. Edwin Lees). At present I do rai opose : collect any 
eryptogamous orders, emepting those enuaraiod’ the London 
Catalogue, 7th ed.; viz., Filices, Lycopodiacea, : Maraitoasiags 
Equisetaces, ecimens chiefly represent 
the Malvern ae and to those botanists who collect in other 
parts of the c yl should feel much obliged for ——. in 
forming the sollte, which, I need hardly say, while in my pos- 
session, would be at the service of any who might wish to coneudle it. 
I should of course be erat to supply, as far as I could, the wants 
of others from the plants of this ree od. I should add 
that there are many Malvern and Teme Valley plants I also should 
be very glad of. My address is 2, Commercial Buildings, Malvern 
Link.—R. F. Townprow.

ot live to complete it. His notes, however, have fallen into most 
the order. It is especially useful as clearing up Braun’s work, and 
describing, or settling down, the very large number of plants to 
which he has given manuscript names in public herbaria. 
The classification is mainly the same as that adopted in the 
Author’s previous works; the number of genera has inane been 
increased to five. Wader Nitella 70 species are included, of which 
17 are here described for the first time, viz _:— monodactyla, poly- 
gyra, glomerulifera, prelonga, remota, Robertsoni, dispersa, pseudo- 
flabellata, capitellata, aa, Asagrayana (Nordst.), microglochin, 
conglobata, diffusa, polycephala, trichotoma and Lechleri. Under Toly- 
pella there are 8 species, of which longicoma, apiculata and californica
