 1. c. 259. Wytham. Moulsford. Ashampstead. Welford. Hampstead 

 Marshall, &c. 



A very flaccid form, var. umbrosa, Parnell, 1. c. 74, has been seen in 

 a damp wood at Padworth, where a glaucous-leaved form was also 

 noticed by the roadside. 



A white-anthered form is not unfrequent. 



On dry hedge-banks Poa praUnsis is found as the var. arida, Parnell, 

 1. c. 74 ; the slender form found on wall-tops, &c., is called muralis by 

 Parnell, and a slender form with the lower branches of the panicle 

 suddenly bent downwards, as in Glyceria (Panicularia) distans, found 

 under trees or in shady places, is the var. retroflexa, Parn. 1. c. 74. 



A luxuriant dark green form, described by Parnell as var. planiculmis, 

 I.e. 74, I have seen at Hinksey, Moulsford, &c., but these forms appear 

 to me to be rather states than true varieties. 



A curious form, with long lower branches to the panicle, as in Poa 

 cosiata, Schum. Enum. PI. Saell. 1. 28, occurred at Hermitage. 

 Poapratensis occurs in all the bordering counties. 



P. trivialis, Linn. Sp. PI. 67 (1753), and Herb. Rough Stalked Meadow 

 Grass.

 Native. Pratal, &c. Meadows, pastures, borders of fields, damp woods, 



roadsides, &c. Common in all the districts. P. May-July. 

 First record. Poa trivialis. Bird Grass, Dr. Noehden. Moist meadows, 

 &c., a valuable and productive grass, Mavor's Agr. Berks, 1809. Very 

 common in the meadows at Blewbury and elsewhere, Mr. J. 

 Lousley in Russell's Cat. 1839. 

 Poa trivialis is subject to considerable variation. 



Var. KOELERi (DC. Syn. Fl. Gall. 131, as a species) = var. glabra,'Doe\\, 

 Rhein. Fl. 92, teste Hackel, probably var. pai-vijlora, Parnell, 1. c. 35, is 

 the woodland form with smaller and paler florets and smoother leaf- 

 sheaths, which occurs in damp woods and shady ditches \ as Wytham 



1 Made synonymous with Poa alpina in Index Kewensis ; surely in error.
