PLANTS FOUND IN KERRY. Ill 



J uncus tenuis Willd., an addition to the Irish Flora, was the 

 most interesting plant found ; a note on its occurrence and 

 localities will be found in Journ. Bot. 1889, p. 335. 



Nitella uracil is Agardh, is also most probably an addition to our 

 Flora, its only claim to be considered Irish having hitherto been 

 the unsatisfactory record, " Glencree, D. Orr," where it has not 

 been found subsequently. I gathered this minute plant, growing 

 with Xaias flexilis, Nitella traitslucens, and N. flexilis, at the south 

 end of Caragh Lake ; it came up in some abundance on the mud 

 adhering to the prongs of a small dredge kindly sent to me by the 

 Messrs. Groves, which I found most useful. 



Scirpus parvulus R. & S., was discovered growing in great abun- 

 dance along the tidal portion of the River Cashen, above Cashen 

 Bridge. This find was the more welcome, since the only other Irish 

 locality for this Scirpus was the mouth of the Avoca River, Co. 

 Wicldow, where I fear the plant has been completely destroyed by 

 the new harbour-works. 



A most unexpected plant found last summer was Poh/</unum 

 arifolium L., a native of Canada and the United States, in low 

 grounds. I am not aware of this plant having hitherto been 

 recorded among British aliens. This desperately prickly Poly- 

 gonum was growing abundantly on the dry stony bed of a small 

 stream at Castle Cove, on Kenmare Bay, about six miles east of 

 Darrynane. It occurred within a few hundred yards of the sea, 

 just above tidal influence, and below a small pool apparently used 

 for washing clothes by the few cottagers in the neighbourhood. 

 The Polygonum was usually but a few inches in length, but some 

 of the plants I gathered had branches over a foot long. I find it 

 hard to account for the presence of this small annual here. 

 Tillage is rare in the neighbourhood, and neither mills nor harbour 

 near ; however, my further investigations here were cut very short 

 by a drenching thunderstorm. 



Simethis bicolor Kunth. I was glad to find that this plant has 

 a wider range than had hitherto been supposed. I found the 

 Simethis in many spots between Darrynane, its recorded locality, 

 and Reenronee, a small point in Kenmare Bay, some eight miles 

 further east; it also occurred more than a mile inland, about half- 

 way between these points ; while about Darrynane it extends from 

 Lamb's Head on the south, to Sheehan's Point on the north, with 

 many intermediate localities. 



This extreme south-west corner of the county seems also to be 

 the head-quarters of Microcala filiformis and Carex punctata, both 

 of which are very abundant here, though the Carex is almost 

 restricted to Kenmare Bay. 



Pilularia globulifera L., new to the south of Ireland, was also 

 found last summer, growing sparingly in a few inches of water in 

 the Upper Lake, Killarney. 



As to the Kerry Potamogctons of 1889, I have again to thank 

 Mr. Arthur Bennett for his kindness in looking over several 

 puzzling plants. Among these was a large gathering of the 

 Putamogetun I had sent him m 1888, labelled " /'. polygonifolius,
