Fr. Glen Lyon, but not common. — H. sparsifolium Lindeb. Glen 

 Lyon (5 m.). — H. gothicum Fr. Glen Lyon (5 m.), and near

 — H. Dewari Bosw. Glen Locbay, near Kiilin ; Glen Lyon (4 m.). 

 H. prenanthoides Vill., H. crocatum Fr., and H. corymbosum Fr. 

 Glen Lyon (7 m.). — H. reticulation Lindeb. By B. Dochart, and 

 in Glen Lochay, near Kiilin. Gathered with us by Rev. E. S. 

 Marshall, and so named by him and Mr. Hanbury. Also in Glen 

 Lyon (7 m.), and at Fortingal. — H. umbellatum L. In Glen Lyon 

 (4 m.), and at Culdamore. — H. angustum Lindeb. (H. croca- 

 tum Fr., var. angustatum Fr.). Two miles up Glen Lochay; For- 

 tingal ; Linn of Campsie. 



Vaccinium uliginosum L. Near Fortingal, N. of B. Lyon. 



Arctostaphylos Uva-ursi Spreng. Lower N. slopes of Meall 

 Garbh ; scarce. • 



Loiseleuria procumbens Desv. E. ridge of Cam Mairg. Not 



seen elsewhere in the Fortingal district. 



Pyrola minor L. Bocky burn N. of mountain between Ben 

 Lawers and Meall Garbh. — P. secunda L. Near the burn on the 

 way up to Meall Ghaordie ; at a rocky break in the Allt Dubh 



Galair, Meall-na-Saone. 



Veronica serpyUifolia L., var. humifusa Dicks. Near Cam Mairg. 



Melampyrum sijlvaticum L. Between one and two miles up Glen 

 Lochay ; very fine. 



Mentha piperita L. (an escape ? on waste ground sometimes 

 flooded, away from houses), Plantago maritima L., and Betula 

 denudata Hook. Glen Lyon (5 m., 4 m., and 2 m.). 



Salix stipularis Sm. In leaf only, but no doubt this form of the 

 hybrid (S. cinerea X viminalis). — S. cinerea x phylicifolia. Some 



five or six gatherings from Kiilin, chiefly near R. Dochart. Also 



in Glen Lyon (4 m.). — S. aurita x cinerea (S. lutescens Kern.). By 

 R. Dochart and a little way up Glen Lochay, Kiilin. — *S. aurita x 

 Lapponum. A strong male bush on steep rock high up in Coire 

 Ardran, with leaves just intermediate between S. aurita and 5. 

 Lapponum ; a smaller, greener bush was growing close by, which 

 looked as if it was a separate plant, but it may have been 

 connected underground ; the situation was one of those which alpine 

 willows love, as if conscious of a secure position from which they 

 can defy attack. This is the first time a living plant of this hybrid 

 has been observed in Britain. About a fortnight later we were 

 fortunate enough to discover a second station for it, this time a 

 female bush in a rather more accessible place, on rocks about two 

 miles N. of Ben Lawers. This corresponds well with Scandinavian 

 specimens of aurita and Lapponum; the leaves are nearer the 

 latter, but in their twisted tip, slight serration, and stipules 

 present on stronger shoots, show the aurita element; the ovaries 

 are long and narrow for Lapponum, the style and stigmas rather 

 shortened, and the scales narrow (oblong-lanceolate) but much dis- 

 coloured. The catkin is curved and has the look of aurita ; so has 

 the year-old wood, but its bark borrows a darker hue and a tendency 

 to shine from Lapponum. — S. aurita X nigricans. We gathered leaf*
