When on dry ground or in shallow water, but especially when grow- 

 ing among the loose stones, where it is only covered with water dur- 

 ing winter, or by occasional floods, the whole plant is very hairy, with 

 the leaves remarkably attenuated at the base, almost stalked. 



Chara latifolia occurred sparingly about a quarter of a mile below 

 Portumna-bridge ; thus affording a second habitat for that very dis- 

 tinct species. It may, however, be well to mention, that the Shan- 

 non affords an outlet to Sadiston-lake, where I first found the plant. 



Lastraa Thelypteris was also observed in a boggy wood in the 

 Marquis of Clanricarde's demesne, much finer than I ever saw it else- 

 where. Some of the fronds being eighteen inches long, and well de- 

 veloped every way. 



Sesleria cccrulea, which has hitherto been considered a scarce grass 

 in Ireland, forms the principal portion of the pasture in some parts of 

 the Marquis of Clanricarde's demesne, growing to the verge of the 

 Shannon. Mr. M'Nab of Edinburgh, and a party of Scotch botanists, 

 who visited Ireland a few years ago, found the Sesleria in a similar 

 situation in the Co. Galway, where it appeared to that experienced 

 and acute observer, a different-looking plant fi'om that he had been 

 in the habit of seeing on the Scottish mountains, as he pointed out to 

 me last season, showing that the Irish plant is much more slender 

 than the Scotch one, with longer leaves and longer culms, characters 

 which do not alter from cultivation. They are certainly very distinct 

 varieties, if not species. 



Spiraa Filipendula. A solitary specimen was found in the Mar- 

 quis of Clanricarde's park, which is chiefly interesting on account of 

 its being an addition to the Irish Flora. I had however received the 

 roots in very considerable abundance last spring, from the neighbour- 

 hood of Gret, Co. Galway, where it must grow abundantly, scarcely 

 a sod of Gentiana vema, which it came with, being without roots of 

 the Spiraea. 



Several other plants, which do not occur generally, were observed 

 on this occasion ; and I have no doubt that any botanist who locates 

 himself a few days at Portumna, during the month of July, will be 

 able to employ his time profitably.
