 gonidia have been observed on the same plant.

North Bay. Rare. 

 Dasya arbuscula Ag. 



South Bay and Carnehan Bay. Rare. 

 Lauren cia pinnatifida Lamx. 

 Lomentaria kaliformis Hook. 



North Bay. Not common.

BOTANICAL NOTE. 

 More Additions to the Wensleydale Flora.— I have to report 



the discoveiy of two more plants here, a Bur-Reed and a Grass, which are, so far 

 as I know, quite new to Wensleydale. 



The Bur-Reed of this district, that growing in Hawes brook, in Ellerbeck by 

 Woodhall, and in the Bain at Semerwater, is Sparganuaii neglectiim Beeby ; not 

 the form of current text-books (S. raniostiiii Huds. ) given therein as having an obovate 

 truncated drupe, with a short, abrupt beak ; but the newer type or sub-species 

 described and figured by Mr. W. H. Beeby in the July number of the Jourjial of 

 Botany (vol. xxiii., p. 193). This neglected form has sessile fruits, densely 

 aggregated into heads, of course, as in S. rauwsiiui, but each drupe would appear 

 to have a much less marked tendency to develop two seeds, and, partly in 

 consequence of this perhaps, is more elongated ('more than twice as long as broad, 

 exclusive of beak), more spindle-shaped, narrowing gradually upwards into the long, 

 slightly curved, persistent style (beak). The anthers seem to be longer, too, in the 

 Wensleydale plant than in ramosiun, but I have only been able, yet, to compare 

 them with one batch of specimens from near Bedale. The habit and stature of this 

 nev/ Bur-Reed are said to be quite like those of ordinary ra7}iosu?n, though I fancy 

 it is, if anything, a smaller, less robust plant (here it is 2 to 2% feet high only), with 

 paler green foliage. If Yorkshire botanists will this month, and the next, examine 

 the Bur- Reeds of their respective localities, and report which ' species ' they find 

 prevail, to Mr. Beeby (14, Ridinghouse Square, London, E.C.)> or to me, the 

 object of this note will be attained. 



The Grass, new to District vii. (Upper Yore) of Baker's 'North Yorkshire,' is 

 Calai?iagrostis epigejos Roth. Baker gives it as a plant of the lowlands of the 

 central vale of York only, at from o to 150 yards. I have just detected it growing 

 in plenty in ' Backwater Spinney' — a small marshy wood, a quarter of a mile to 

 the east of Hawes station, the altitude being a few feet above that of the river-bed, 

 which at Hawes New Bridge is 750 feet ; i.e. an extension in upward range of 

 more than 100 yards beyond any locality of which Mr. Baker in 1862 was 

 cognizant. 



Whilst writing, I may mention another ascertained extension of range. The 

 Yellow Flag, Iris psendacoriis., L., grows in the Backwater at Hawes at 750 feet 

 alt. [150 yards given by Baker], and this Hawes form is a. gemiimis E. B. Syme, 

 with short claw, and broad, clear, deep yellow blade, not the commoner form, 

 b. acoriformis Bor., which has sepals of afpaler yellow with a deep orange spot at 

 the base, and a long claw prominently veined with purple. The Yorkshire 

 distribution of both varieties wants working out. — F. A. Lees, Hawes, Wensley- 

 dale, July 13th, 1885.
