NOTES ON SOME PLANTS OF MID-PERTH 167 



Garth Castle, often as the forma latifolia W. E. Linton. An 

 abnormal form of the type with sooty styles was collected on 

 slopes above the Lyon, about six miles above Fortingal. 



■'H. sparsifoliuvi Lindeb. This name is suggested by Mr. 

 Linton for a yellow-styled hawkweed found on low rocks at the 

 north-east end of Loch Tummel. It closely resembles one from 

 near Inchrory, Banffshire, which his brother placed here, and 

 under the type, in 1905 ; also (allowing for difference of situation) 

 some much taller specimens from the Shee Water, two miles below 

 Spital of Glen Shee, 1892. I think that all of them belong to 

 this species. 



H. strictum Fr. Near the Keltney Burn, and in two or three 

 places by the Lyon, but not plentiful. 



H. reticulatnm Lindeb. Frequent and often remarkably fine in 

 Glen Lyon ; sometimes the leaves are untypically efloccose beneath. 



H. coryinbosum Fr. var. salicifolium (Lindeb.). Keltney Burn, 

 and a little above Bridge of Lyon. 



Armeria maritima Willd. A very fine form of this, which I 

 believe to be Syme's var. planifolia, grows in wet ground on the 

 north side of Creag Mohr, from 2200 to 2500 ft. 



Mimulus moschatus Douglas. Well established in a muddy 

 ditch about five miles above Fortingal, Glen Lyon. 



Euphrasia gracilis Fr. A form with white (instead of blue 

 or reddish) flowers was noticed on a dry bank near the road, two 

 miles west of Lawers Inn. Fine E. Bostkoviana Hayne {E. offici- 

 nalis L., vera ?) is abundant in the low ground. 



BhinantJms Drummond-Hayi Druce. Very local on the 

 northern slopes of Creag Mohr, at 2200 ft. 



Melampyrum pratense L. var. ■■'ericetorinn Oliver? Bushy 

 hillock east of Garth Castle, in plenty. The name was given to 

 it by Mr. Salmon, and it seems to agree quite well with the 

 description in Phytologist, 1852, p. 678 ; but I have not seen Irish 

 specimens. In the stronger plants the bracts are decidedly 

 toothed, not entire, as in var. montanum. I have found precisely 

 the same thing at Wybunbury Bog, Cheshire. 



Mentha piperita L. Established in bushy ground near the 

 Lyon, three-quarters of a mile below Fortingal. Mr. Salmon 

 determined it as a. officinalis (Hull), our normal form. 



Polygonum aquale Lindman. Common in Glen Lyon, below 

 Fortingal ; named by Dr. Moss. It varied a good deal ; one of 

 the forms agrees with the plant figured by Syme as P. aviculare 

 var. arenastrum. 



Betida alba L. x pubescens Ehrh. var. microphylla E. S. Mar- 

 shall. Two trees of this hybrid combination, which seems to be 

 new, grew with the parents by the Allt Coire Pheiginn, west of 

 Garth Castle, at 700 ft., both being good intermediates {B. pube- 

 scens var. microphylla is frequent in the district). Dr. Moss and 

 I agreed in this determination. 



Ahius glutinosa Gaertn. The only form observed is var. 

 microcarpa Eouy {teste Moss). 



Salix caprea L., var. sphacelata Wahlenb, Allt Coire Pheiginn
