7(5 THE JOUBNAL OF BOTANY 



his work was later practically restricted, as the TPlora of the North- 

 east of Ireland contains a reference to a -MS. list of these prepared in 

 L860-87. Lett's first notes in this Journal appeared in 1 895, to 

 which for many years he contributed; his longest contributions 

 were the list of mosses and hepatics of South Donegal (1903,356), 

 the description of a new hepatic {Adelanthus dugortiensis), and 

 notes on Hypopterygiuvi, with a description of a new species, //. im- 

 migrans (1904, 201, 249). 



Lett's most important production was the List with Descriptive 

 Notes of British Hepatics (1902), which was somewhat severely 

 criticized by Mr. Symers McVicav in this Journal for the same 

 vear (p. 421); some of the corrections were embodied in his Cata- 

 logue of British Hepatics (1904). Lett was an original member 

 of the Moss Exchange (dub; his "Census Report on the Mosses of 

 Ireland" (Proc. It. I. Acad, xxxii. ; 1915) contains a list of records 

 for the botanical divisions of Ireland (on which he had written in 

 this Journal for 1900 (p. 412) with a valuable bibliography and 

 biographical notes ; biography always interested him, and formed 

 the subject of his presidential address to the Belfast Naturalists 1 

 Club in November, 1912, on " Botanists of the North of Ireland'' 

 (Proc. Belfast Club, 2 ser. vi. 615-G2S). Much of Lett's work was 

 done in conjunction with a brother clergyman, C. H. Waddell, who 

 predeceased him in 1919 (see Journ. Bot. 1919, 358).

SHOUT NOTES. 



Carex Pair.ei in Ireland. Last summer Mr. A. \V. Stelfox 



sent me a couple of stems of the above that had been gathered in 

 Co. Dublin, and further details of the find have just come to hand. 

 The plant was noticed first by Dr. Scully in 1919 by the roadside near 

 Sandyford, about 8 miles S.E. of Dublin, growing on the sides and 

 summit of a dry, rocky and sandy ditch; this was reported, under the 

 name of C. m'uricata in the Irish Naturalist, 1919, p. 90. In 1904, 

 when Colgan's Flora of Dublin appeared. C. Paircei had scarcely 

 been recognized by botanists in these Islands, and in that work 

 G. contigua only appears as a very rare plant with only one accepted 

 station — " Near Stepaside on the way to Holly Park (Moore). Cyb." 

 Mr. Stelfox thinks tins may he the same locality as Dr. Scully's present 

 one. The latter, I am told, is sandy and dry, and this coincides with 

 my experience of the habitat in which I have seen the species growing 

 in England and Wales, a favourite one being a well-drained hedgebank 

 or sandy common. Mr. A. B. Jackson, however, says (15. E. C. Rep. 

 1914, 170) that the plant seems to prefer somewhat moister situations 

 than G. contigua ; my experience is rather the opposite. He also 

 mentions that he has seen Irish examples of G. Paircei, but no localities 

 or counties are given. — C. E. Salmon.
