WATSON BOTANICAL EXCHANGE CLUB REPORT, 
1900-1901. 
[Tue following notes are exatnontt from the Report of the 
Watson Botanical. paeanee Club for 1900-1, which was issued 
in August last. Messrs. K. S. and 6. E, Salmon were distributors 
for the year; the core of =. Club is Mr. H. S. Thompson, of 
80, Waterloo Street, Birmingham.] 
Lepidium ruderale L. Dry Mo Aylestone, eset Aug. 
1900. This, a few years ago, w found in one locality ; now 
it has bavome more plentiful in aa locality, and a cat one is 
recorded on the opposite side of the town.—W. Bell. Correct. 
This rapid spreading of L. ruderale is occurring in many of the 
larger towns. About London it is already one of the commonest 
waste-ground weeds.—S. T. D[unn 
Silene conica L. Near Barketene, Dorset, June 14, 1900. This 
plant, hitherto queried as an alien for the county, appears to me on 
investigation to be thoroughly native; for, though the area in which 
I saw the plant is very restricted, it is a perfectly natural one, and 
the Rev. W. Moyle Rogers tells me that it is nearer two miles than 
one distant from that reported by Mr. Hussey in 1886. —

The small-flowered Malvas of North Europe have been much 
confused. Linneus (Fl. ae. Sah, 248) under M. rotundifolia 
writes : pud nos flor muniter minores, corolla omnino 
alba ; Sisathalinie ropa aol majore purpurascente obvia 
te isti_apud exteros.” It thus appears that he included 
n 
and ‘about equal to the calyx. Most English botanists mean b 
M. rotundifolia Linnzus’s aces after M. borealis Wallm. (M. pu- 
silla Sm.) has been removed. But in Koch’s Synopsis, ed. 3, 1. 
418, and elsewhere, M. neglecta Wallr. is kept up, while 1. rotundi- 
folia L. refers only to smaller-flowered plants (M. borealis Wallm.). 
M. parviflora L. is readily separable by its enlarged fruiting calyx, 
and M. nicaensis by its broad outer calyx-segments. All the plants 
submitted to me are M. borealis Wallm.—8. T. Rae 
is now abundant there. Five or six years ago it was voreat in & 
garden at Bickley, about 14 miles from gi 
planation of its appearance eerste ; no one in the istrict has 
a botanical garden.—D. T. Playfair
