found ill widely separated localities. It appears to be a 

 decreasing species, and seldom forms berries. 



Galium ^^alustrc, L. — The plant of this coast has the 

 stems and margins of leaves always more or less rough 

 with prickles, and the cyme varies accordingly to whether 

 the plant be in dry or wet soil. G. uliginosum has been 

 recorded from this district, but the specimens so named 

 which I saw were a marsh form of G, palustre. I have 

 looked without success for G. uliginosum on the mainland 

 and inner islands of this part of the coast. 



ValcriancUa olitoria, Poll. — I had formerly thought this 

 to be a colonist, but I now consider it a rare native on 

 the sandy shore. It "occurs in similar places on the island 

 of Coll, remote from cultivation. 



Erica cinerea, L. — The white - flowered plant appears 

 to be a permanent form, at least much more so than in 

 the case of Calluna. I have known individual plants 

 for some years, one for eight years : and a friend has 

 known a plant in its native locality for more than 

 thirty years. I have not known a plant of Calluna to 

 retain white flowers in its native locality for more than 

 five years, usually less. The leaves of the white-flowered 

 Calluna are lighter green than in the normal plant. It 

 is probably a more tender condition, but whether it 

 returns to the ordinary plant or dies out, I have not 

 been able to ascertain. 



Arnieria maritima, Willd. — Tlie range in altitude of 

 this plant on the hills is 1550 ft. to 2860 ft. I have 

 not seen it between the former height and the shore. 

 Our mountain form is not the var. 'planifolia, Syme. 



Veronica serpyllifolia , L. — The common low ground 

 plant appears always to have pubescent capsules. 



Eaphrasia officinalis, L. — The foi'ins known from this 

 district are — E. horealis, Towns. ; not uncommon in un- 

 cultivated pastures, especially about the shore. E. hrcvipila, 

 Burnat and Gremli. ; very common, most frequently in 

 the more cultivated pastures. E. curia, Fries. ; I have 

 only found this in one place at 1300 ft. altitude. E. 

 occidental is, Wettst. ; Mr. Townsend found this in short 

 pasture at Morar Bay, Arisaig, also the hybrid occi- 

 dentalis X hrevi/nla. E. gracilis, Fries.; very common in
