height for want of its coveted excess of moisture. The 

 other species are also carefully cultivated there, and 

 seem as if naturalized. 



4. Calamagrostis Lapponica. Lapland Smallreed. 



Root creeping, perennial; the stem cylindrical, smooth, 

 ribbed, about three feet high ; joints wide apart, smooth ; 

 leaves long, narrow, acute, rough all over except the back, 

 generally rolled in ; sheaths smooth, striated, upper one 

 longer than its leaf; ligule prominent, pointed ; panicle 

 compound, erect, compact, three to four inches long, pur- 

 plish-brown in colour; spikelets numerous, situated on 

 rough branches, which are placed in clusters at certain dis- 

 tances along the rachis ; outer glumes equal, narrow, 

 pointed, purple or brownish, toothed along the keels ; 

 flowering glume as long as the outer glumes, five-ribbed, 

 rough, bifid at the summit, awned ; awn arising below the 

 centre of the keel, reaching a little beyond the apex of the 

 glume, rough, bent, slender ; palea shorter than the flower- 

 ing glume, smooth ; scales pointed. 



Very nearly allied to the last species, if not a variety 

 of it. Dr. Parnell treats the two as quite distinct, while 

 Mr. Bentham and others regard them as " identical or 

 very nearly allied." The former gives the distinctive 

 features thus : — 



" Calamagrostis Lapponica. Ligule acute. Hairs 

 shorter than floret. Awn arising from below the centre 

 of the flowering glume." 



" Calamagrostis stricta. Awn arising from below the 

 centre of the flowering glume. Hairs not longer than 

 the floret." 



This species was found near Loch Neagh and else-
