and S. repens, Linn., are not uncommon in Coll ; the former is 

 apparently absent from Tiree. Jimi2:ferus communis, Linn., forma^ 

 is locally in abundance as a prostrate plant. 



Tiree is more flat than Coll, and, having no shelter, there is a 

 complete absence of trees and gardens. No E,ubi could be seen, 

 and only three dwarf bushes of Bosa canioia, Linn., clinging to the 

 face of a rock, were met with. Some interesting plants noticed 

 were Ranunculus Drouetii, Godr., H. Baudotii, Godr.. R. marinus, 

 Fries, the first "satisfactory" specimens of Fries's plant which 

 Mr. Arthur Bennett, F.L.S., to whom I submitted them, has seen 

 from Scotland; Hij^puris vulgaris, Linn., var. Jiuviatilis, Weber, 

 with shorter leaves than usual ; Ajnum nodijiorum, Reichb. fil., 

 var. ocreatum, Bab., A. inundatum, Beichb. fil., Sium erectum, 

 Huds., (Enanthe Lachenalii, C. Gmel., Plantago Coronopus, Linn., 

 var. maritima, Grenier k Godr., a distinct plant, with broad 

 thick fleshy leaves. Mr. Arthur Bennett identified this plant, 

 which is given in Flore de la France, vol. ii., 1850. It has not 

 been hitherto recorded from Britain, I believe. Alisma Plantago- 

 aquatica, Linn., var. lanceolatwm, Afz., Fotamogeton nitens, Web., 

 P. filiformis, Nolte, Car ex disticha, Huds., C. flava, Linn., var. 

 ci/peroides, Marsson, this variety being more common than the 

 type, Deschampsia discolor, R. & S. ; Festuca rottbodlioicles, Kunth, 

 is locally common. Equisetum ^J>fi^z*s^re, Linn., var. nicdiwi, 

 Newm., occurs on the sandy shore of Loch Yassapol. The Cha- 

 racete gathered were, from Tiree — Chara fragilis, Desv., and 

 C, fragilis, Desv., var. delicatida, Braun, C. aspera, Willd., 

 C. contraria, Kuetz., C. vulgaris, Linn., and C. vulgaris, Linn., 

 var. 2yctpillata, Wallr., Nitella traiislucens, Agardh, and JV. opaca^ 

 Agardh. From Coll — G. fragilis, Desv., var. delicatula, Braun, 

 G. asp)era, Willd., var. suhinermis, Kuetz., and a form approaching 

 G. aspera, Willd., var. curia, Braun, G. hispida, Linn., and 

 G. vidgaris, Linn. Messrs. H. and J. Groves, F.L.S., kindly named 

 nearly all the above. I am much indebted to our Corresponding 

 Member, Mr. Arthur Bennett, F.L.S., for having examined several 

 bundles of plants sent to him from both islands. Of the 357 

 species and varieties noticed, there were upwards of 40 species 

 which had not been recorded for vice-county 103, in which these 

 islands are included. The Charace?e, with the exception of Ghara 

 fragilis, Desv., were, I think, new to the vice-county.
