REPORT FOR 1879.

Brotherston ; also from a garden tree at Alstonfield, Staffordshire, 
by Rev. W. H. Purchas. Both plants are accepted by Dr. Boswell 
as what he intends by the above name. 
Callitriche verna , L. A number of plants thus named are sent 
by some of the members. A plant collected by Mr. W. H. Beeby, 
from a pool near Partridge Green, W. Sussex, 17th June, 1879, is 
believed by Dr. Boswell to be C. vernalis , the specimens sent being 
too imperfect to be sure ; Mr. Briggs thinks it may be pedunculata. 
The Rev. W. H. Purchas sends specimens from near Warslow, 
N. Staffordshire, 18th September, 1879, which Dr. Boswell supposes 
to be vernalis. Dr. Boswell says that “ it differs from S. hamirtata in 
the sub-obovate fruit, shorter styles, and more persistent bracts, but it 
may be C. hamulata after all, in which case C. verna , vernalis is 
unknown to me.” Dr. R. L. Baker’s plants, from Kirby-le-Soken, 
Essex, July, 1879, are named by Dr. Boswell C. platycarpa , and he 
thinks to this name must be referred the Rev. Augustin Ley’s 
plants, viz., verna , from Orcop, and obtusangula , from Allensmore, 
Herefordshire. Mr. T. R. Archer Briggs reports that the Kirby-le- 
Soken plant is certainly not verna , but platycarpa or obtusangula ; he 
thinks the latter. He does not think the Rev. A. Ley’s plant verna , 
while that from Rev. W. H. Purchas is similar to a Plymouth plant 
which he supposes to be verna , but hardly knows how to separate 
from hamulata. 
Helosciadium repens , Koch. Collected in August and September, 
1879, by Dr. F. Arnold Lees, in the “ Line-ponds,” Skipwith 
common, South-east Yorkshire. Dr. Lees gives the following note : — 
“ This plant — abundant enough in the shallow and muddy ponds 
named — is not the repens figured in Eng. Bot. ; nor does it seem, in 
the ponds and neighbouring ditches, to pass either into that or 
ordinary nodiflorum. It is a strikingly procumbent and widely 
creeping plant, bearing very much the same relation to E.B. repens as 
Ranunculus cu-reptans does to pseudo-repta?is. It does not seem to 
perfect its seeds ; after swelling to about half the size of the ripe 
cremocarps of H. inundatum , they wither and drop off. It perpetuates 
itself solely by its creeping stems which root at each node, and, when 
broken off, each length of stem that has a leaf tuft upon it seems 
able to grow. The primary root, and each node, bear a tuft of long- 
stalked leaves, with lobed or deeply cut pinnules and an umbel of 
flowers upon a common peduncle, which is quite as long as the 
leaves, and, like them, appears to be radical, from springing directly 
from the rooted portion of stem. Each rooting node when detached 
produces stolon-like stems on each side, that in their turn root and 
produce leaf-tufts and umbels. The common peduncle is always 
involucrate, but the number of the pedicellar bracts is not always 
precisely the same as there are rays in the umbel, although they 
generally agree.” Dr. Lees thought it might be the var. longiped- 
unculatum of Schultz, but on seeing the notice of it in Schultz’s 
“ Archives ” he found that this name could not be applied to the 
Yorkshire plant. It will be as well to give the original description of 
H. nodiflorum, var. c . pedunculatum from the “Archives,” 1855, PP- 
1 35- 1 38 : — U (H. repenti-nodiflorum , F. Schultz, autrefois; H. repens ,
