The typical form suberectus of R. Flammula passes into 
the form pseudo-Te]jtans by innumerable intermediate con- 
ditions, so that it is not always possible to assign the one 
name or the other to some of these forms. I exhibit an 
extreme form of pseudo-reptans which I distributed last 
year to botanists through the Botanical Exchange Club ; it 
occurred in a small bay . about half a mile below The Ferry 
on the western side of Windermere, where it was wholly 
submersed in from half an inch to six inches depth of water. 
It was a somewhat strong-growing form, having numerous 
creeping stems, radiating from a central root, and branching 
at their upper end. The separate plants interlaced in all 
directions, and covered the bottom of the water with a dense 
growth ; a complete individual plant would cover a patch 
two feet in diameter; and its small flowers, never raised 
more than an inch above the ground, were completely sub- 
mersed. The stems were somewhat robust, and their nodes 
produced two or three long rootlets, and with usually only 
a single linear leaf, but rarely a mass of roots, or a tuft of 
leaves, as in the filiform stems of reptans. The plant, how- 
ever, advances beyond Dr. Boswell’s definition of the variety, 
in possessing arched internodes for all internodes after the 
first, which latter is erect, but very short. It is the most 
extreme form of pseudo-reptans which I have met with, 
and may possibly be Nolte’s var. radieans. 
From the recently published “Lake Flora” of Mr. J. G. 
Baker, it would appear that the pseudo-reptans form is 
frequent on the margins of the English Lakes. I have 
myself only noticed what may pass as this form on By dal 
Lake, but the true reptans is quite likely to occur on the 
sandy shores of any of our lakes, northern or southern.
