306 TRANSACTIONS OF THE [Sess. lxxxiii 



3. var. angustata, Wahlenb. (sub Arundo), Fl. Lapponica, 

 28 (1812). Margin of Loch Watten, Caithness, G. LilHe sp. 



4. var. 2^tdUda, Ruprecht, Hist. Fl. Petrop., 35 (1845). 

 Hockham, Norfolk. Mr. Robinson, 1914 '.. 



Hooker, Brit. Fl., ed. 1, 32 (1830), gives another station, 

 '' Rescobie, four miles from Forfar. T. Drummond," and 

 this is repeated by Hooker and Arnott in 1860, but I can 

 find no specimens extant from there. 



Ascherson and Graebner, Flora Mitteleup. 208 (1899), 

 have a " var. viridis Torges," whether this is the same as 

 Ruprecht's pallida I do not know : and they have a var. 

 interrupta, but later than Wahlenberg's, and they do not 

 refer to that. It seems that our plant may not be the 

 same as the Central European one, or perhaps as some of 

 the Scandinavians, but the whole genus in Europe requires 

 revision, no two authors agreeing as to the species, varieties, 

 or hybrids. It varies greatly in the length of the glumes 

 and the relative length of the hairs and awns. In the 

 .specimens in which the glumes are so reduced in length 

 (3 mm.): why is it the hairs are not proportionately re- 

 duced ? But this is not the case in the Norfolk specimens, 

 in some of which the hairs are nearly as long as the glumes 

 (" half as long in the type "). In some of the Caithness 

 specimens the glumes are unusually long, and these have 

 been called var. scotica by Mr. Druce, but Timm, in Mag. 

 fur Nat. und Oec, Meklenburg (1795), called this C. neg- 

 lecta /3 stricta. This name neglecta was used by Erhart 

 in his Calamarioe, Dec. 3, 113 (1786), and in his Beit., vi, 

 137 (1791), sub Arundo. Looking at specimens from all 

 our recorded stations, I am inclined to think we have more 

 than one species under it, but it requires careful collation 

 and comparison with authentic specimens. As none of our 

 Floras contain descriptions of the varieties, I here append 

 them : — 



2. borealis (as a species) Laest., in I.e. 



" var. A. arista subdorsali, lana corollea brevior, caulis 

 foliata. Panicula stricta patens, foliis radicalia dilatata, 

 aspera, stricta, elongata," a. paludosus. 



" /3 arenivaga, Lae.st., panicula stricta patens, radix longe 

 latique repens, folia stricta dilatata, sub exsiccatione con- 

 voluta, filiforma."
