SHORT NOTES, 
Tue Arran Istze Pyrus.—In his monograph of the _— Sorbus, 
Dr. Hedlund (Kon. Sv. Veten. Akad. Handl. p. 60, 1901 ~2) raises 
the puzzling form peo Arran to the rank of a species, as Sorbus 
arranensis. This does not seem to agree with Prof. Koehne’s view 
(Journ. Bot. 1897, p "99) that all the Arran plants are hybrids be- 
tween Aria suecica at ne and Sorbus Aucuparia. Mr. Ley’s Py 
minima becomes Sorbus minima Hedlund, and he retains it as a 
species. So far as the Arran plant is concerned he seems to have 
seen little material. Some years ago Mr. G. Nicholson collected an 
e 
for a series of specimens. Perhaps the true rank of these forms 
must await cultivation in some botanic garden.—Arruur BEnnetT.

towards a confirmation of Mr. Leighton’ s note in this Journal for 
1866 (p. 806), i.e. * First discovered in England in 1787, at Lakeby 
Carr, near Boroughbridge, Yorkshire, by the Rev. James Dalton.” 
That it was found before 1807 is certain from this specimen in 
from 1804 to 1806. Scheuchzeria is No. 208; this would bring it to 
the early part of 1806, and it was doubtless gathered ™ hae in the 
year before. It is certain that he was at Lakeby Car 1790, as 
Mr. Wilkinson tells me there are specim ef of étliet lait so Tale 
ized and dated in the York Philosophical Society’s Herbarium. The 
dates of the specimens of Scheuchzeria from Lakeby Carr in that her- 
barium are 1807, 1822, 1823, 1839, 1870. Mr. Leighton remarks (FI. 
It was discovered in Shropshire in ae ee The ‘* some abun 
is now a thing of the past at Bomere, though it may still exist at 
Mr. Beckwith’s station: ‘‘In the sed of 1881 Mr. La Touche 
and I conld only find a few plants on the mossy margin of Bomere 
ool” (Journ. Bot. 1882, 366). In Perthshire careful and repeated 
search for it has been in vain. In this Journal for 1898 (p. 381), 
I mentioned I had not heard of its recent occurrence in Cheshire, 
but I overlooked the Rev. E. 8. Marshall's record, /.c. 1896, 136.

Riccrocarrus natans (p. 189).—Mr. Bagnall’s note reminds me 
that I co iiasied this species (and haye specimens in my herbarium) 
from a pool near Little Baddow, Essex, on Sept. 14th, 1881. It 
=: be worth while putting this on record. I also collected it in
