Note on Juncus alpinus, Vill. By F. Buchanan White, 

 M.D., F.L.S., F.E.S. 



(Read 9th February 1888.) 



For some years past it has been suspected that Juncus 

 alpinus was a member of the British Flora, on account of the 

 existence of one or two herbarium specimens which probably 

 (but only probably) belonged to that species. As one of 

 these reputed examples came from Perthshire, the species 

 had a special interest for me, and consequently I have been 

 always keeping a lookout for it, and urging my friends to do 

 the same. The search was all in vain, however, till one day 

 in August last, when, wishing to see Astragalus alpinus 

 growing in the Perthshire station where it was discovered 

 by my friend Mr P. Neill Eraser, I came upon some rushes 

 which, though immature, bore a suspicious resemblance to 

 the long sought-for JuncAis aljnnus. Specimens of these 1 

 planted in the garden, where they ripened capsules, and 

 proved my suspicions to be correct. (I may mention that I 

 saw both the Astragalus and the Oxytropjis in flower. The 

 latter is 0. uralensis, and not 0. campestris* as suggested — 

 from flowerless specimens — at a former meeting of the 

 Society, but this has already been proved by Mr Brebner, 

 who gave me specimens of each some years ago. It is very 

 much to be hoped that the station for these rare plants will 

 not become known to others than true botanists.) 



* 0. campestris is not uncommon near Loch Loch (7 or 8 miles distant from 

 the Astragalus alpinus station), wliere it was discovered by Rev. J. Fergusson 

 in 1887. In visiting its locality this season (1888) I hnnd Juncus alpinus and 

 Kobresia caricina. — F. B. W.
