CONTRIBUTION TO A FLORA OF THE OUTER HEBRIDES 167 



about 20 feet above the sea, on the cliffs of Gribon, "where 

 in storms the spray may reach it," Mrs. Crichton to Mr. A. 

 Somerville. In Arctic Norway it grows at various altitudes 

 from 1000 to 4050 feet, and blooms from the 8th of June to 

 1 2th of September, extending up to 71 n' N. lat. 



ARENARIA SERPYLLIFOLIA, L., var. MACROCARPA, Lloyd. " Fl. Loire- 

 Inf.," 1844 = ^4. Lloydii, Jordan. Sandy meadow, Balelone, 

 North Uist, Dr. Shoolbred ! 



DROSERA ANGLICA, Huds. Near Loch Arynuish and Lainvagha in 

 Lewis, Gorrie. Queried for Shetland in "Top. Bot.," 1883, 

 but found by Mr. Beeby (sp.} in 1889. 



GERANIUM ROBERTIANUM, L. Among large stones, foot of cliffs, 

 2 miles east of Awhuinnsuidh, W. S. Duncan. Shetland, 

 Beeby, 1890 ; thus on record for all the counties of Scotland. 



RADIOLA LINOIDES, Roth. Eye Peninsula, Lewis, Gibson, sp. 



TRIFOLIUM PRATENSE, L., var. MARITIMA, Marss. Sandhills, Kirki- 

 bost Island, North Uist, Dr. Shoolbred. 



VICIA SYLVATICA, L., forma SUBROTUNDATA, miM. Rocky coast of 

 Scarp, off Harris, in the north of the island, where it grows 

 in some quantity, festooning the steep cliffs in places, W. S. 

 Duncan, sp. 



Contrasted with specimens from Obbe, North Harris (W. S. 

 Duncan, sp.}, the Scarp plant looks very different, with its 

 small subrotund leaflets, giving the plant more the look of 

 some forms of V. septum, L. From the mainland examples 

 the specimens differ in the less portion of the peduncle occupied 

 by the flowers (i- only as against \ usually), the calyces are 

 much more strongly veined, and the teeth longer and more 

 attenuate. 



In Caithness examples I find the majority of the flowers 

 with well-defined holes at the base of the calyces, but I have 

 been unable to find any cause. Mr. Scott-Elliot gives two 

 humble bees, Bombus muscornm and B. hortorum^ as visiting 

 this species, but does not mention how they act with regard 

 to the flowers.
