In the Highlands of Scotland. 



Found on Ben Nevis by the late Mr. J. T. Mackay, a most excel- 

 lent observer, who sacrificed his health and life to the too ardent 

 pursuit of botany and horticulture. See Engl. Bot. 



Perennial. Julij. 



Root slightly creeping. Whole plant more dwarf, slender, and de- 

 licate than the last, pale and somewhat glaucous. The leaves 

 are narrow, roughish above. Stipulas all lanceolate and acute. 

 Panicle rather close, with us more or less zigzag, especially 

 the lower part. Spikeleis not heart-shaped, but all ovate, of 3 

 Jlorets, rarely 4, or 2, glaucous, coloured like those of P. alpina, 

 but paler, and essentially distinguished from that species by the 

 connecting complicated web at their bases, while the keel only 

 of each, not the sides, is silky. 



Having now ascertained, by Swiss specimens, the true synonyms 

 of this rare species, I adopt its original name, as pointed out by 

 Professor Schrader. 



Mr. Don found this grass most frequently viviparous. 



4. P. hulbosa. Bulbous Meadow-grass. 



Panicle close, sliglitly zigzag. Spikelets four-flowered. Flo- 

 rets hairy at the keel, connected by a web. Leaves finely 

 serrated. Stem bulbous at the base.

Perennial. April, Maij. 



Root a tuft of small, ovate, white scaly bulbs, as truly such as the 

 bulbs of a Lily or Garlick, and, like them, throwing out fibrous 

 radicles from their base ; wliich h;ii)iKiis when the autumnal 

 rains fix them in the moistened sand. Early in spring a dense
