42 ANNALS OF SCOTTISH NATURAL HISTORY 



B. arvensis, L., introduced or casual in 74, 85, 86, 90, 92. (The 



records of this species are too much confused with some of the

except 112. 



(B. pinnatum, Beauv. , recorded in error from 85 and 94.)

occurrence in fields and waste places, italicum (Braun) being 



especially common. 

 L. temulentum, Z., 72, 82f, 87!, 88 cas., 89 cas., 92 cas., 95f(?).

 Agropyrum caninum, Beauv. , except 82, 84, 98 t 99, 102, 104, 



107 (?), 109, 110, 11-.'. 



var. b. Donianum (F. B. White), 88. 

 A. repens, Z., all. (Mr. G. C. Druce records vars. maritinmm, 



Druce, and ccesium, Doell., from 105, W. Ross.) 



var. Leersianum, Gray, 75, 78, 86, 88, 91, 92, 105, 107, 



109, 112. 

 A. pungens(P), Roem. and Schult., 75 (?), 103, io6(?).

 Lepturus filiformis, Trin. (including var. b. incurvatus (Trin.\ 72, 



_73> 7S> 82, 83(?), 84, 85, 100, 102, io 3 (?). 

 sEgilops triuncialis, L., and ;. caudata, L., casuals, 92. 

 Nardus stricta, Z., all. 

 Hordeum secalinum, Schreb. ( = H. pratense, Huds.), 73, 81 (in 



Berwick), 86, 87 (reported from 75, 83, 85). 

 H. murinum, Z., 75, 80-86, 89, 90, 917, 927, 95!, 1097 (from 



1 1 1 in error). 

 H. marinum, Huds. ( = H. maritimum, With.), 84, 87, 90 (? error); 



very doubtfully native. 

 Elymus arenarius, Z., 72 (?), 75, 82, 85, 90-97, 100, 101, 104, 



105, 107-112 (extending its range and abundance). 

 (Several cultivated cereals, e.g. Avena sativa, A. orientalis, Triticum 



sativum, and other " wheats," Hordeum distichum, H. hexasti- 



chum, Secale cereale, etc., occur frequently as casuals in many 



districts.)
