178 TRANSACTION'S AND TROCEEDINGS OF THE [Sess. LXiii. 



and Nirpliar lutca occur in a small state, which is generally 

 due to their being in shallow water, or in lakes at a higher 

 altitude. The small state of Nuphar lutca from this 

 district was at one time referred to N. intermedia ; but 

 this latter plant, which is probably a hybrid between 

 y. lutca and X. pumila, has not been found here. Lobelia 

 Thyrt manna is abundant in lochs up to about the same 

 altitude as Nymphcea, which is 1100 feet, Fofamogeton 

 'prcelongus was, until recently, considered to be rare on the 

 west coast, but it occurs in most of the deeper lochs in this 

 district. As it is usually confined to the deeper parts, it is 

 seldom seen except by dragging. This is also to some 

 extent the case With. ■ Nitclla transluccns, which sometimes 

 occurs in such large masses in deep water as to exclude 

 other vegetation. In such places it is sterile, with elongated 

 branches ; but this species is also found occasionally in 

 shallow water. 



A considerable part of the low ground of the district is 

 covered by a moss, which is less than twenty feet above 

 sea-level. Over most of it, and extending a short distance 

 up the higher adjoining ground, is Rhyncliospora fusca in 

 great abundance. This moss occupied at one time the 

 Loch Shiel valley, but it has been divided into two parts 

 by a raised beach, on which now stands the village of 

 Acharacle. The plant occurs on both sides of the old 

 beach, and has probably spread from the higher ground 

 after the last elevation of the land. The only other locality 

 in Scotland where the Rhynchoqjora has been found is in 

 Wigtownshire, where it was discovered by Mr. M' Andrew in 

 1887. It is known at sight from the autumnal brown 

 state of li. alba, which is a common plant on this coast, by 

 the latter growing in less compact patches. 



The number of species, excluding casuals and aliens, 

 known from the district may be given as 520. This 

 is taking the " London Catalogue," 9th edition, as the 

 standard, except with Uubns and Hicracinm, where I 

 have followed Syme's "English Botany." In this the 

 fructicose llubi are given as one species, and the hawk- 

 weeds are mostly limited to the species of liackhouse. 

 In giving Watson's types under which the plants would be 

 placed, some of the segregate brambles would probably
