BOTANICAL EXCHANGE CLUB REPORT, 1899. 



[The following are among the more interesting notes published in 

 the above-named Report, which was issued on March 28, and is edited 

 by the Rev. W. R. Linton, the distributor for 1899.— Ed. Journ. Box.] 



Ranunculus scoticus Marshall. Traheen's Lough, Achill Island, 

 W. Mayo, 23rd June, 1899. Just my Scotch pctiolaris, and growing 

 in a similar situation, on the stony margin of the lake. It seems to 

 fruit much more freely than li. FlaiiwuUa. 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. am/ustifolms {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 Flanwmla, 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 B. Flammula is, I know, great, but I am 

 inclined to think scoticus a subspecies." — A. Bennett. 



Arabis ciliata R. Br. var. Jiispida 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 our A. 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 hirsnta 

 appear to be rather subspecific than specific. — E. S. Marshall. 

 '* 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, 8rd and 17th April, 1899. This whitlow grass, which I 

 have observed about Milford for several years, agrees well with 

 Jordan's type-specimens, figure, and description of his K. virescens, 

 except in having narrower capsules with a more wedge-shaped base! 

 It is remarkable for its brii/ht green, fleshy, glabrescent leaves! 

 usually appressed to the ground in a regular rosette, and is a very 

 pretty little plant. I believe it to be a good and perfectly distinct 

 species, well apart from E. prcecox. — E. S. Marshall. 



BuDA MEDIA Dum. var. glandulosa mihi. Hay Cliffs, Dover, 

 Sept. 1899. This curious variety of B. media grew on the bare 

 chalk cliff of Hay, Dover, probably on a slightly more impervious 

 band, in District 7 of the Flora of Kent, where this plant is referred 

 to on p. 67. It was originally referred to in the Phytoloijist, n. s. 

 vol. v. p. 33 ; but the authors of the Flora of Kent say that the
