142 REPORT OF THE LONDON BOTANICAL EXCHANGE CLUB. 
In the potato fields round Balmuto, this small-flowered form of 
G. Tetrahit exclusively prevails ; the large-flowered form, var. genuina, 
I have seen only once in a wood not far from Balmuto ^oi. The 
var. bifida is rarely above a foot high, varies with red or white flowers, 
with the lower lip notched or nearly entire, and its lateral lobes re- 
flexed or spreading, so that the small flowers are really the only dis- 
tinctive mark of the variety. 
Galeopsis versicolor, Curt. Auchtertool and Pitkinnie, Fife ; J. Bos- 
well-Syme. This plant is abundant here, growing with G. bifida, but 
showing no tendency to variation. I am now convinced it is a ver- 
species, and that I was wrong in placing it as a subspecies of G. Te- 
trahit in the third edition of ‘ English Botany.’ 
Pulmonaria angustifolia, Linn. Near Newport, Isle of Wight; 
Mr. F. Stratton, who finds both the long-styled and the short-styled 
plants. In reference to this, I may mention that I have found the 
long-styled form of P. officinalis abundantly fertile, producing long- 
styled and short-styled plants, though I had in my London garden the 
long-styled form only. 
Chenopodium rubrum, Linn. Weston Green, FIO Examples 
sent in order to illustrate the conversion of variety Pseudo-botryoides 
into almost typical rubrum. On Weston Green, in the parish of 
Thames he 
water of the pond evaporates under the summer sun, a gravelly strand 
or shore is left bare, and is much trodden by the geese. Here, in 
past years, the prostrate variety of Pseudo-botryoides has regularly oc- 
curred in the autumn. In the hot season of 1868, evaporation was 
more rapid, exposing a much wider strand, and one earlier free of 
water. The tramp of the geese followed the retiring edge of the water ; 
and on the less-trodden outer side of the widened strand, the secl 
developed into the upright, branched or unbranched, forms now sent ; 
some of them fair typical examples of Chenopodium rubrum. Unfor- 
tunately, very few of the larger examples were dried, through an inten- 
tion to return for more not having been soon enough carried into 
effect. The variety Pseudo-botryoides was so named because it had 
been mistaken by various botanists for the true C. botryoides of Smith. 
Its proper relation to typical C. rubrum is now placed beyond ques- 
tion. (See * English Botany,’ 3rd edition.) "—H. C. Watson.
