Ley. In the collection of Prof. Reichenbach, so often mentioned, 
there are four specimens of this, one from Montan de Bourget, pres 
Chambery, Huguenin. This is the normal form in which the lowest 
pair of pinnce only are separated. Another from Wellenger Berg bei 
Arnstadt Oswal, in which few of the leaves only have even the first 
pair of pinnae separated ; and thirdly, from Lingerberg in Thuringia, 
Sinowheit, which has some of the leaves with one pair of pinnae 
separate, but the greater number only lobed. The fourth specimen is 
from St. Maurice, Yallesia. This last specimen is more like P. 
fennica than any of the others, having one or two pair of separate 
pinnae, and the remainder of the leaf less prolonged than usual — 
rhombic-triangular in one leaf, ovate-triangular in another ; neverthe- 
less from the blunt apices of the pinnae and lobes, with the terminal 
tooth small, and the margins entire towards the base, and on the 
inner side. I consider it as P. semipinnata , with which it agrees in 
the closer and finer felting of the under side of the leaf. In my own 
collection I have normal specimens from “ Mont Bosson, pres Lau- 
sanne, Leresche,” and a very complete series in flower and fruit, from 
M Huguenin, of Chambery. These specimens have some one, some 
two, and some even three pairs of separated pinnae, while other leaves 
have nine of the pinnae separated. Garcke in the “Flora of Nord- 
and Mittel-Deutschland,” calls it Pyrus Aria- aucuparia, Irmisch,” 
and Wirt gen in the “ Flora der Preussischen Rheinprovinz ” names 
it S. Aucuparia-aria , Wirtgen — a better name than Irmisch’s, as 
it is nearer P. Aria than P. Aucuparia. — John T. Boswell, July,

Callitriche obtusangula, Le Gal. “ Marshes near Deal, East Kent, 
June, 1874. I had the advantage of seeing a large patch of this 
plant growing in the midst of C. verna. The occurrence of the two 
species in close proximity enabled me at once to detect a difference 
between them, principally from the fact that the former appeared of a 
much lighter green colour. It will undoubtedly be found to be much 
more widely distributed in England when specially looked for. Whilst 
arranging the British collection at the Edinburgh Botanic Garden, I 
came upon some specimens of this plant fastened down with C. verna , 
and labelled ‘ C. verna , Ponds, Coombe Yalley, Westbury, near 
Bristol. Comm. Carpenter.’ This is at present then its most westerly 
record, though no doubt requiring to be more fully confirmed.” — J. 
F. Duthie, May, 1875. 
Apium graveolens , L. ‘ CuLoss,’ Perth. “As I see in ‘English 
Botany ’ that ‘ Apium graveolens ’ is not known on the east coast, per- 
haps you may not yet have seen any specimens from Culross (Perth).
