B. horcalis Druce and B. Drummond-Hayi Druce occur to- 

 gether on Meall nan Tigearn, as well as on Argyllshire Ben 

 Laoigh ; more often I have found borealis by itself, and it seems 

 to have a more general distribution in Scotland. These two 

 plants stand well apart from our other British yellow-rattles, 

 being decidedly alpine (they rarely descend to 1500 ft., but ascend 

 to 3000 ft. at least), and possessing a constant character in the 

 calyx, which is more or less thickly clothed with short, stiff, 

 appressed hairs, and not merely ciliate, like the rest. The flowers 

 are of a vivid though not deep shade of yellow, being frequently 

 tinged with red-brown or inclining to orange in B. Drummond- 

 Hayi. Sterneck calls the latter an autumnal plant ; but I can 

 find no appreciable difference in their flowering season. B. borealis 

 is relatively stouter, unbranched, with much broader and more 

 obtusely toothed leaves, when luxuriant ; B. Drumviond-IIayi has 

 a more slender habit, narrower and more acutely toothed foliage, 

 and the larger specimens produce a few small slender abortive 

 lateral branches. When seen growing side by side they are by 

 no means hard to distinguish, as a rule ; but whether they ought 

 to be specifically divided is a debatable point. I believe that 

 Sterneck is fully justified in refusing to combine them with 

 B. gi'o&nlandicics Chabert, which has the calyx-surface perfectly 

 glabrous, as Ostenfeld has done. 



*SaIix deciinens Hoffm. Island in the Orchy, about a mile 

 below Dalmally ; one handsome bush, apparently not planted, nor 

 could I see it anywhere near in cultivation. 



S. arbmcula x herbacea (male) ; S. myrsinites L. forma ^^jrocw/i- 

 bcns (Forbes). Meall nan Tigearn. This mountain should repay 

 a special search for hybrid willows, S. arbuscula and *S'. herbacea 

 being plentiful, though S. Lapponum is scarce. I believe that I 

 also saw a fair amount of S. pliylicifolia and S. nigricans; but I 

 had no time for detailed investigation. 



Orchis maculata L. Only seen in low-lying stations, and 

 rather local ; a few white-flowered specimens occurred near the 

 Awe, a mile or two above Taynuilt. 0. ericetorum Linton is much 

 more plentiful, and ascends a good way up the hills ; I found 

 them growing together in two stations, but they were too far 

 advanced for hybrids to be determinable, if any existed. 



Junciis tenuis Willd. was collected in three distinct localities, 

 scattered over a length of eight or ten miles. 1. Roadside, four 

 miles up Glen Orchy; a single tuft. 2. On both sides of a byroad 

 leading from Dalmally Bridge to Craig farmhouse ; abundant for 

 nearly one hundred yards. 3. Near the terminus of a long dis- 

 used railway line to some granite quarries, at 500 ft., two to three 

 miles from Loch Av/e Station, at the foot of the corrie of Ben a' 

 Bhuiridh ; scattered over a space of about thirty yards. In all 

 these cases it was associated with other Junci (no fewer than five 

 in the principal station), and no introduced plants were seen near. 

 Evidently such artificial localities, combining sufficient moisture
