typical examples ; but the rather low elevation may account for 

 this, and I cannot refer them to anything else. 



H. ruhicundum F. J. Hanb. Stream-sides in Fin Glen, 

 between 1600 and 2000 ft., very scarce; differing from type in the 

 ligules being very ciliate and the styles very dark, but Eev. 

 E. F. Linton agrees with me that it belongs to this species. 

 Only recorded from Killin, in Perthshire. 



H. argcnteum Fr. Kocks by the Lyon, two miles below 

 Fortingal, as well as higher up the river. 



H. Sommerfeltii Lindeb. Rocks at the east end of the Stuich- 

 an-lochan, Ben Lawers, from 2700 to 3000 ft. ; the dark-styled 

 form. 



H. i^seudonosmoides Dahlst. Locally frequent by the Lyon, 

 and on rocks above it. 



H. callistojjhyllum F. J. Hanb. Typical, but very rare, l^y 

 the stream in Fin Glen, at 1600 to 2000 ft. 



H. sylvaticum Gouan var. micracladium Dahlst. Allt Odhar, 

 at 1700 ft. ; scarce. 



H. variicolor Dahlst. Not uncommon ; but both Mr. Linton 

 and I fand it hard to draw a clear line between this and H. rotun- 

 datum Kit. The leaves are, as a rule, more elongated ; when in 

 shade, their blotches tend to disappear. Keltney Burn ; Allt 

 Odhar ; streams below Meall Garbh (north side) ; rocks above the 

 road from Bridge of Lyon to Fearnan. In this neighbourhood its 

 range is from 2000 down to 1400 ft., with one exceptional station 

 at about 400 ft. 



■■'H. subnlatidens Dahlst. Mr. Linton concurs in referring to 

 this some luxuriant, shade-grown specimens, with remarkably long 

 foliage, found by the Allt Odhar, at 1700 ft. 



H. rivale F. J. Hanb. Stream-sides, Fin Glen and Allt Odhar, 

 at 1700 ft. 



H. sagittatum F. J. Hanb. var. suhhirtum^ . R. Linton. Fin 

 Glen ; Allt Odhar ; Inverinain Burn ; by the Lyon, near Invervar. 

 Locally frequent, ascending to 2000 ft. 



H. euprepes F. J. Hanb., type. An alpine black-headed form 

 occurs on cliffs at the east end of the Stuich-an-lochan, Ben 

 Lawers, at nearly 3000 ft. — Var. glabra turn Linton. In many 

 places by the Lyon, often very luxuriant, with lower peduncles 

 up to nine inches long ; near Garth Castle ; Fin Glen ; eastern 

 cliffs of the Stuich-an-lochan, Ben Lawers. From 300 to 2700 ft. 

 -H. farrense F. J. Hanb. One fine plant, in a shady ravine 

 300 yards north of Garth Castle. 



U. custales Linton. Fin Glen and Inverinain Burn, between 

 1600 and 2000 ft. 



H. ccBsiovmrorum Lindeb. Allt Odhar, and by the Lyon, near 

 Invervar, at about 700 ft. 



H. dissimile Lindeb. Rocks above the road from Bridge of 

 Lyon to Fearnan (1400 ft.) ; Allt Odhar (1700 ft.) ; the usual 

 Scottish form. 



H. Deivari Bosw. Near the Keltney Burn, &c. 



H. gothicum Fr. Abundant on a grassy, bushy hillock near
