io8 ANNALS OF SCOTTISH NATURAL HISTORY 



Arctic Norway 1 up to 70 50'. Norman describes a var. 

 dispersiflora, seemingly only differing in the raceme being 

 "dispersed, not secund." It there flowers from July 29 to 

 September S. 2 



Moncses uniflora, A. Gray, has its northern limit in 

 Scotland about one mile north of P. secunda, where it grows 

 and flowers freely, in company with Linncea borealis (Dr. 

 Joass, JT/.). 



In Ireland, P. secunda is rare ; there is a specimen in 

 the Belfast Museum, labelled " Derry, Mr. Brown." Robert 

 Brown lived in Derry about 1801. It was found by Dr. 

 Moore in Derry about 1836, but remained unrecorded till 

 found by Mr. Fetley on June 26, ipoi. 3 Mr. L. Praeger 

 found it in Co. Fermanagh in 1904, on "Upper carbonifer- 

 ous limestone, capped by Yoredale sandstone, at an alt. 

 of 1135 ft. ; here it occurred in abundance with P. minor, 

 P. inedia, Sesleria, Asplenium viride, etc., growing not only 

 among the stunted heather and in the Sesleria patches on 

 the cliff, but even covering bare slopes of orange sand formed 

 by the disintegration of the rock, and on a mossy boss under 

 a low sandstone scarp." 4 In the " Flora of Dumfries " 

 (1896), 114, Mr. Scott-Elliot describes its localities: "On 

 dry whinstone rocks, with very little soil, in sun, but partly 

 wind-sheltered, in narrow corries, under the influence of the 

 humid atmosphere from the burns." 



In the fourth volume of the " Cyb. Brit.," 175-233, under 

 " Zones of altitude," secunda is given from 3, 4, 5 ; 3 no 

 doubt applying to the Moray 5 coast station. 



To show the boreal-alpine tendency contrast the follow- 

 ing, found in Wales : 



Dryas octopetala Carnarvon to Orkney. 

 Potentilla alpestris Montgomery to W. Sutherland. 

 Carex pauciflora Carnarvon to Orkney. 

 Lycopodium annotinum Carnarvon to Orkney. 

 Epilobium alsinifolium Carnarvon to Shetland.
