puzzling to the novice—the notes under “ Eleocharis palustris (?)

much space as Pieractan these two standing first in quantity. 
its entry both under te name and the incorrect one of Bursa is 
a little confusing. Mr. C. E. Britton has made a careful atoey 
from authentic epee of Mott’s proposed varieties: this we 
venture to extract almost in full: 
* Capsella Dusstepastorss Medic. var. bifida Mott. Lower 
Morden, Surrey, May 6, 1912. This is one of the most distinct 
forms of Capsella, and matches exactly an authentic plant of Mots 
lent me by Mr. Jackson. It will be noticed that there is a 
tendency to bear two forms of capsules, but, as the shorter and 
broader form is on the primary stem, this difference is probabl 
due to a variation in the vigour we the plant’s vitality dependent 
on age, and plants of Mott’s gathering show a similar peculiarity. 
Whether this variety is identical with the bifida of Crépin is un- 
certain 
a Capsella agrestis J aa Molesey Hurst, Surrey, May 5, 191 
This plant agrees well with the description of C. agrestis in 
Jordan’s Diagnoses, p. 339, and, moreover, is identical with 
Continental plants $0 labelled in Herb. Mus. Brit. Whilst the 
London Catalogue ignores all varieties of Capsella Bursa -pastoris, 
Mr. Druce, in his List of British seeps gives ten, most of these 
bearing the same names as Mott’s varieties. I am inclined to 
think that these diverse — = po ossbly erroneous, and that all

arrangement, iSuclan’ s C. agrestis must occupy a prominent place. 
gem: 
An examination of type-specimens of Mott’s varieties (lent me by 
Mr. Jackson) show that densifolia, stenocarpa lyrata, stenocarpa 
seh a oe and the form subsequently distinguished as var. 
cuneata, are all too closely allied to each other and to C. agrestis 
Jona. to admit of separation even as sub-va: ction: Mott’s named 
examples show that coronopifolia differs fas densifolia only in 
the form of the radical leaves. The var. coronopifolia often has
