86. GRAMINA. 231 



in English Botany seems to have been drawn from a plant 

 of true B. arvensis, though not good. It is quite possible 

 that there are two species, the pratal and agrestal, in- 

 cluded here. 



1356. Bromus mollis, Linn. 

 1356, b. (B. pseudo-racemosus, Lond. Cat.) 

 (B. racemosus, Lond. Cat. edit. 3.) 



Area general. 



South limit in Cornwall, Isle of Wight, Kent. 



North limit in Shetland, Orkney, Hebrides. 



Estimate of provinces 18. Estimate of counties 82. 



Latitude 50 — 61. British type of distribution. 



Agrarian region. Inferagrarian — Superagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 350 or 400 j^ards, in East Highlands. 



Range of mean annual temperature 52 — 43. 



Native. Pratal, &c. This very common grass is 

 usually well known to British botanists, and in its typi- 

 cal form is scarcely ever mistaken. But in the remarks 

 under B. secalinus, I have intimated that a slight variety 

 of it is confused by some botanists with the pubescent 

 state of B. secalinus. On the other side, a non-pubescent 

 state, usually with a less branched or more elongate 

 panicle (B. pseudo-racemosus), is also confused with B. 

 commutatus. Thus, the name of " racemosus " signifies 

 either commutatus or pseudo-racemosus, the latter a 

 variety of B. mollis. Mr. Syme thought B. moUis an 

 introduced species in Orkney, and a similar suspicion 

 attaches to the more elevated localities for it in the High- 

 land provinces.
