234 ANNALS OF SCOTTISH NATURAL HISTORY 



O. ERICETORUM, Linton. 



HABENARIA VIRIDIS, R. Br. Very abundant in the east on grassy 

 knolls (upper glacial drift) at 180 feet. 



Var. BRACTEATA, A. Gray. Coast sands, Newton, North 

 Uist, Shoolbred, sp. 



H. BIFOLIA, R. Br. Frequent from Amhuinnsuidh to Beitarsaig in 

 North Harris, also between Lustkentyre and Borve in South 

 Harris. 



H. CHLOROLEUCA, Ridley. In South Harris, at the foot of a small 

 heathery knoll, and on the coast of the Sound of Harris opposite. 

 A plant of it growing in a cornfield showed that before the 

 flower is quite expanded the backs of the sepals are of a bright 

 green colour. 



JUNCUS GERARDI, Lois, var. SALSUGINOSUS, Regel, ex Ledebour ("Fl. 

 Ross," iv. 1853, p. 230). Much smaller than the type, 2 to 

 7 inches high, long-creeping and rooting, sending up stems 

 about every inch, perianth equalling the capsule. Sandy coast 

 of Kirkibost island, 15/7/98, Dr. Shoolbred. 



RUPPIA ROSTELLATA, Koch. Brackish pool at the head of the bay 

 south-west of Harris, W. S. Duncan. 



Doubtless abundant in the many brackish waters, but Mr. 

 Shoolbred's specimens were too young to be sure of, and Messrs. 

 Babington, Balfour, and Stirton name only the aggregate species. 



SCIRPUS FLUITANS, L. Given by Balfour and Babington without 

 locality. Mr. Shoolbred gives North Uist, Harris, and Taran- 

 say, and Mr. Somerville adds South Uist, this latter being the 

 floating form with fine leaves. A species that seems to have 

 few varieties, var. terrester, Meyer ("Chi. Hann." 1836, p. 600), 

 being the only one given by Ascherson and Grsebner. 1 This 

 I have from Ditton Marsh, Surrey, gathered by Mr. H. C. 

 Watson 2 in 1868, and in W. Gloster by Mr. W. White. I 

 have a curious variety from Surrey in which the plant is 

 elongated to 28 inches, with a replant stem throwing up fascicles 

 of leaves every f inch. I can find no mention of such, and 

 propose to call it / reptans, though this generally means 

 " rooting as well." 



CAREX BINERVIS, Sm., var. SADLERI, Linton. North Uist, 1894, 

 Dr. Shoolbred ! = C. In'nervis, Sm., var. alpina, Drej. 



C. OEDERI, Retz. Barra, A. Somerville ! . 



AGROSTIS CANINA, Linn., var. PALLIDA, Schk. South Uist, A. 

 Somerville, sp.
