152 The Irish Naturalist. April, 



the plant is completely established, but I have 110 doubt in my own 

 mind that to some wreckage containing Californian produce we must 

 attribute the occurrence of this Western American species in Ireland. 

 Notwithstanding the wider spread of its ally, S. angustifolium, I am a little 

 sceptical as to that plant being aboriginal in Ireland, although its curious 

 appearance in outlying spots is at present without a completely satis- 

 factory explanation. 



SclIIa vcrna, Huds. — Raven Point, Co. Wexford. 

 J uncus bufonius, L. — Ascends to 1,900 feet in Kerry. Var. fas- 



cicularls, Koch. — Raven Point, Co. Wexford. 

 J. acutus, L. — Abundant in the sand-dunes of Raven Point, Co. 

 Wexford. Var. effusus, Buchenau. — A lax-flowered plant which 

 occurs in some quantity with the type in the above locality, must I 

 think be referred to this variety, which has not hitherto been re- 

 corded for the British Isles. 

 J. silvaticus, Reich, {aciiliflorus). — Ascends to 2,100 feet in Kerry. 

 Lenin a trisulca, L. — Rossmore, Co. Galway. 



Potamogreton Kirkii, Syme. — Still in good quantity at Maani. A 

 beautiful plant, with elegantly graceful submerged leaves. It has 

 been suggested that P. natans ma}' be one of its parents, but I failed 

 to see traces of that species in it. 

 P. pcctinatus, L., var. scoparius. — Lady's Island Lake. 

 Ruppia rostellata, Koch.— Lady's Island Lake. 

 Eleocharis acicularis, R. Br.— Rossmore, Co. Galwa)-. 

 Agrostls canlna, L., var. Iaevis, Hackel in litt. — " Differt a typo 

 foliis omnibus planis latiusculis (circ. 2 mm. latis) prorsus laevibus, 

 paniculse ramis spicularumque pedicellis laevibus, spiculis majus- 

 culis." 

 This grew near the summit of Brandon, and at once attracted my at- 

 tention, reminding me somewhat of the variety scotica, which I gathered 

 on Ben Ray, in Scotland, but I found differed from it in several par- 

 ticulars. Professor Hackel therefore names it as a new variety. The 

 large spikelets and broader leaves at once mark it from the type. In the 

 var. grandifolia, which I first discovered in Ross-shire, the leaves are 

 narrow, and the panicle branches are not smooth. 

 A. tenuis, Sibth. {vulgaris, With.), forma grand if Iora, Hackel. — 



Brandon. 

 Holcus Ianatus, L. — Ascends to 1,900 feet in Kerry on Connor Hill. 

 Slegrllngria decumbens, Bernh. — Ascends to 2,100 feet on Brandon. 

 Seslerla caerulea, Ard.— Ascends to 1,500 feet 011 the Ben Bulben 



range. 

 Cynosurus crlstatus, L — Ascends to 1,900 feet on Connor Hill. 

 Koeleria graciiis, Pers.— Derryuane ; Roundstone. A very stout- 

 spiked form on Ben Bulben requires further study ; it ascends on 

 that range to 1,800 feet, and Professor Babington erroneously thought 

 it might be K. vaksiana. It belongs to the cristata group. 

 Fcstuca rubra, L.— Ascends to 2,900 feet on Brandon, and to i,Soo 

 feet on the Ben Bulben range.
