num, aS I saw it last sammer in the Pyrenees near La 
Vernet: ae ‘abont t 2000 ft, sittecaly had a very distinct habit of its 
own, unlike that of either montanwn or lanceolatum, and was easily 
recognizable at a glance. The shorily-stalked rites alternate in 
the middle and upper portions of the stem (for in spite of Gmelin’s 
opigitial description, I think the lower leaves, at ‘leact are oman 
opposite), and the /anceolatum-like small pinky flowers, combin 
form a plant at once striking and unfamiliar to an English ratte 
The Scottish examples in the Reigate Museum are unfortunately 
not complete plants, but are evidently forms nearer lanceolatum ; 
but their leaves ze broader-based, and not truly lanceolate, as in 
that species. ev. E. S. Marshall has seen the specimens, and 
believes them to ‘3 rightly named collinum.
