of the following subspecies and varieties :—M. paludosa, Sole, M. 
cardiaca, Baker, and M. gentilis, L. 
Calamintha menthifolia, Host, var. Briggsii, Syme. The same con- 
tributor sends specimens of the plant named after him by Mr. Syme. 
It seems a slight variety only, differing from the type in its larger size, 
longer peduncles, and more hairy stems and leaves. 
Myosotis repens. Sent by Mr. Parker from Mochtry, Montgomery- 
shire. New to sub-province 18 of Cyb. Br. Supp. 
Chenopodium album, L. An interesting series is contributed by Mr. 
Watson of this species to illustrate the three varieties, candicans, 
viride, and virens, given in the Lond. Catalogue. “The name paga- 
num, adopted by Syme in E. B. iii, is probably applied to the same ` 
variety as virens, but the authors of the ‘Flore de France’ make it 
synonymous with viride,” Watson. Mr. W. sends what he thinks 
“ intermediate links ” between the varieties, but whether they be so in 
any true sense is to be doubted. As far as experiments have yet gone, 
they tend to show that these forms come up true from seed. 
Atriplex erecta (Huds.?), E. B. Mr. Syme and Mr. Dyer both 
send specimens of this plant, collected at Twickenham, Middlesex. 
The former writes, “In spite of the perianth being usually smooth 
or but slightly muricated, I believe this to be the plant of Smith and 
probably of Hudson. The murication or smoothness of the perianth 
is not a constant character; it varies in seedlings from one parent- 
plant of 4. patula, angustifolia.” In the Lond. Catalogue this plant is 
placed as a variety of 4. hastata, L., but in the new edition of Eng. 
Botany it stands under 4. patula, L. It is better so placed, for 
though it has some characters approximating it to A. deltoidea, Bab., 
yet, from the shape of the leaf, it must be considered closer to 4. an- 
gustifolia, Sm. The A. erecta, * Huds.,” of Bab. Man. and other 
English authors, is called 4. serrata by Syme. It is a very common 
cornfield plant. A few specimens are sent by Mr. Syme for comparison 
with 4. erecta. 
Polygonum “mite.” Some specimens from Llanbrynmair, Mont- 
gomeryshire, C. Eyre Parker, were sent out under the above name. 
It should have been altered to P. Hydropiper. Correspondents who 
received any specimens from the above locality are requested to alter 
P. littorale, Link. Handsome specimens of this subspecies of P.
