T]ialictrum minus^ Linn. = T. diuiense^ Dum. Coast sandhills, 
between Marske and Redcar, N.-E. Yorks, 12th and 23rd July 1899. — 
J. CjROVes. “Y! dimefise, Dum. The name T. mitius^ Linn., is too 
indefinite.” — E. F. Linton. 
Ranunculus heterophyllus^ Web., ex p. Hem Mill Dam, Shifnal, 
Salop, July 1899. Mr. Hiern considers this to be near R. radians, 
Rev. — iV. H. Painter. “Yes.” — H. and J. Groves. 
R. peltatus, .Schrank., var. floribundus (Bab.), d'he Lake, Idan- 
drindod Wells, Radnorshire, July 1899. “A weak form.” — P. 
Hiern, FL.S. — ^V. H. Painter. “A small form of R. peltatus •, 
certainly not R. floribundus, Bab.” — H. and J. Groves. 
R. . Near Morecambe, W. Lancs., 23rd July 1899. — J. A. 
Wheluon. “A. heterophyllusP — H. and J. Groves. 
R, scoticus, Marshall. Traheen’s Lough, Achill Island, W. Mayo, 
23rd June 1899. Just my Scotch pefiolaris, and growing in a similar 
situation, on the stony margin of the lake. It seems to fruit much 
more freely than R. Flammula. The first certain record for Ireland. — 
E. S. Marshall. “Herr Freyn (‘B. E. C. Rep.,’ 1898, p. 564) 1900, 
refers this to Wallroth’s var. angustifolius (‘Sched. Crit.,’ 1822, p. 288). 
I cannot agree with him. I have grown the plant for several years 
side by side with a form of Flammula, and the specimens grown by 
me and seen by me in no way agree with Wallroth’s description. See 
note in ‘Ann. Scot. Nat. Hist.,’ 1894, p. 51. The variability of R. 
Flammula is, I know, great, but I am inclined to think scoticus a sub- 
species.” — A. Bennett. 
Arabis ciliata, R. Br., var. hispida, Syme? Origin, Cong, E. Mayo; 
garden, Milford, 6th July 1899. This is the only Arabis that I have 
observed on the limestone about Clonbur and Cong, whence I 
originally brought roots during the winter of 1894-5. It has since 
seeded and spread freely in my garden, keeping remarkably constant. 
The stem-leaves are not auricled but truncate, and it seems different 
from ourH. hirsuta of S. England, agreeing better with book descriptions 
of A. ciliata, var. hispida, Syme, of which I have not seen authentic 
specimens. If this suggestion proves to be correct, no doubt a good 
deal of Irish (probably also of Scotch) A. hirsuta will rank with it. The 
differences from typical hirsuta appear to be rather subspecific than 
spe^cihc. — E. S. Marshali,. “We consider this is A. hirsuta, which 
is distinguished from A. ciliata and its var. by the root-leaves being 
more stalked, the pods longer and narrower, and the seeds (fourteen 
to the inch) more scattered. These features are conspicuous in Mr. 
Marshall’s plant.” — E. F. L. and W. R. L. 
Erophila virescens, Jordan (capsulis angustioribus). Milford, 
Surrey, 3rd and 17th April 1899. No. 2285. ThL whitlow grass, 
which I have observed about Milford for several years, agrees well 
with Jordan’s type-specimens, figure, and description of his E. viresce?is.
