with C. hicuspidata, Craig- an-Lochan, alt. 1800 ft., on a rocky 

 bank close to the stream which flows into Allt a'Mhoirneas near its 

 exit from Lochan na Larige. Mr. Pearson has confirmed the 

 name. — Jungermania atrovirens (Schleich.) Dum. c. per., Craig-an- 

 Lochan, alt. c. 2100 ft., on wet rocks by the side of the stream 

 which comes out of Lochan Tarbh Uisge, and between the landslip 

 and the rock cleft. This plant certainly comes near small J. ripdria, 

 the only difference which I can see being that the perianth is 

 oblong-ovate instead of pyriform as in the latter. I have expected 

 for some time that this plant occm-red in Britain, and have asked 

 correspondents at various times to send rae specimens of small 

 riparia in the hope of finding it, but the Perthshire plant is the 

 only one which I have seen. I think, however, that it will be 

 found in other places, especially in limestone districts, and not 

 necessarily on hills. Herr Kaalaas has confirmed the name of the 

 Craig-an-Lochan plant. — J. quadriloha Lindb. in Arn.&Lindb.Musc, 

 Asias bor. p. 55 (1888), Craig ChaiUeach, alt. 2800 ft., in some 

 quantity on rock ledges on the east side of the hill going from the 

 end of the fence to the summit. Herr Kaalaas writes of this plant : 

 ** Your specimens of J. quadriloha are rather small, and the leaves 

 sometimes trifid instead of quadrifid ; but in the form of the lobes 

 and the sinus they exactly resemble our Norwegian plant." This 

 is a well-marked species, but might be overlooked for J. Flcerkii or 

 J. lycopodioides. It has hitherto only been found in the North of 

 Europe. — J. polita Nees, on wet ground in two localities in the 

 western ravine of Ben Lawers, on the east side of the main stream, 

 between 2700 ft. and 3300 ft. This is a very interesting addition 

 to our flora, and is a well-marked species. The name has been 

 confirmed by Messrs. Pearson and Slater and Herr Kaalaas. — Nardia 

 suhelliptica Lindb. ex Kaalaas, De Dist. Hep. inNorveg.p. 386(1893), 

 c. per., Craig-an-Lochan, alt. c. 2000 ft., close to the locality for 

 J. atrovirens, and near the stream. Herr Kaalaas writes of my 

 plant: " The specimens of N. suhelliptica are a little larger than 

 the plants I have seen from Norway, but in all essential characters 

 they agree very well with the original specimens of Lindberg, 

 especially in the form and structure of the perianth." Although I 

 was able to identify it from the description alone, I cannot yet see 

 how it differs further from iV. ohovata than the alpine form J. 

 spharocarpa, the J. lurida Dum., differs from that species. I do 

 not, however, understand the difference in the perianth which Herr 

 Kaalaas apparently considers of much consequence ; in his De Dist. 

 Hep. in Norveg., it is given as species distinctissima. I do not think 

 that the colour of its rootlets is a character of much consequence, 

 as I observed that ordinary N. ohovata on Ben Lawers had fre- 

 quently more white rootlets than the low ground plant has, and 

 the rootlets of the Perthshire N. suhelliptica have occasionally a 

 faint reddish tinge. — Symers M. Macvicar.

 Webster, of York, is to be congratulated on being the discoverer of 

 this interesting and latest addition to the British Moss Flora.
