I04 ANNALS OF SCOTTISH NATURAL HISTORY 



scaberrima, i-nervis, callo nuda. Palea glumam subaequans, 

 ovalis, obtusa, 2-nervis, inter nervos sulcata. Antherae 3, 

 1.5 mm. Ig. (quam palea paullulo breviores)." 



An interesting paper on this plant, with comparison between 

 it and A. interrupta^ Beauv., by Mr. A. 13. Jackson, appeared in 

 the "Ann. Scot. Nat. Hist." for July 1907. 



Bromus commutatus, Bab.^ var. multiflorus Parn. On waste 

 ground, near Murray field; several. 



B. macrostachys, Desf. A form with glabrous spikelets ; Leith and 

 Slateford ; plentiful. 



*B. macrostachys, Desf.^ var. triaristata, Hackel. Leith ; three or 

 four. 



*B. marginatus, Nees. Leith ; one large plant. A perennial, 

 native of the Western U.S. (California, Oregon, Arizona, etc.). 

 Identified by Professor Hackel, who points out that my speci- 

 men from the plant as originally found agrees better with the 

 type, than do specimens from the same plant grown in my 

 garden. The latter specimens represent better B. marginatus 

 latior, Shear, in "Studies on American Grasses" (a larger and 

 stouter plant than B. marginatus)^ which he first found at 

 Walla Walla, Washington, and which was again gathered " on 

 wool waste heaps at North Berwick, Maine." Shear mentions 

 that it is a very variable species. 



B. moUiformis, Lloyd. Leith ; many plants. Identified by Professor 

 Hackel. 



B. secalinus, Z., var. divergens, Rchb. One fine clump at Pettycur, 

 Fife. 



Cynosurus aureus, L. Two or three plants in an old quarry, near 

 Slateford. 



*Elymus canadensis, L. One plant on waste ground at Burntisland 

 Docks, and one fine plant at Leith. A perennial, native of 

 N. America, Identified by Professor Hackel. 



Festuca ambigua, Le Gall. Several in a sand-pit at Comiston, 



Edinburgh. 



■^Lepturus cylindricus, Trin. A single plant, at Leith. 



*Phalaris brachystachys. Link. One plant at a pit- mouth near 

 Joppa, several at Leith, a few scores at Slateford. Identified 

 by Professor Hackel. 



*P. intermedia, Bosc, var. angusta. Several at Leith. 



*Polypogon maritimus, Willd. Several at Leith and Gorgie, hundreds 

 (along with P. monspeliensis, Desf.) at an old quarry, near 

 Slateford, used as a " toom " for clean refuse.
