1857.] IRISH BOTANY. 213 



their season of flowering, but I brought plants of those which 

 were unknown to me to the Botanic Garden, where they flowered 

 freely last spring. Among them one turns out to be Salix pro- 

 cumbens, Forbes, both male and female plants. Another nearly 

 allied species, with downy germens, and catkins produced at the 

 subterminal buds of leafy persistent shoots, having a more up- 

 right habit than the former, with smaller and difierently formed 

 leaves, has not yet been properly determined. I have considered 

 the occurrence of these species in this country worthy of being 

 recorded, more perhaps on account of their geographical range 

 than for their rarity, they being the only truly northern forms of 

 Willows {Saliw herbacea excepted) which have yet been found in 

 Ireland. I may add that the Benbulben range, as a whole, pro- 

 duces more plants of the alpine type than any other of our moun- 

 tain ranges, and would repay a botanical visit better than most 

 of them, if general herborizing were the only object. 



In the lists of Irish plants supplied by your English correspon- 

 dents who from time to time visit this country, as well as those 

 sent by my friend Mr. J. Carroll, of Cork, I have failed to no- 

 tice included in any of them Myosotis repens, Don, Potamoge- 

 ton polygonifolius, Bourr., and Potamogeton plantagineus, Du- ?/. 

 crtiz, though they are all good species, as that term is generally q I 

 understood, and of frequent occurrence in Ireland. 



With a view of procuring plants and specimens of some of the 

 Robertsonian section of Saxifrages, I paid a hurried visit to the 

 Killarney range of mountains last month, where I saw plenty of 

 all the kinds previously noticed to grow there, with the exception 

 of Sax. eiegans, Mack. Though I searched the locality given by 

 Dr. Mackay, namely, the top of Turk Mountain, I could not ob- 

 serve any plant which was not referable to either Sax. umbrosa or 

 Sax. Geum. 



I had occasion in a former communication to the ' Phytologist,' 

 to remark on the paucity of species produced in a given area in 

 the west of Ireland, compared with the east ; an observation which 

 is exemplified in a remarkable degree by the Killarney district, 

 where mountain, lake, and plain are all present. For instance, 

 on Carntual Mountain, which rises to an elevation of nearly 3350 

 feet above the level of the sea, amongst extensive ranges of lower 

 hills, we might naturally expect to find a considerable number of 

 at least subalpine plants, such as Salices, Hieracia, Carices, etc.,
