384 EHINANTHACEAE 



Hill, Stanto7i. Sunninghill. Bagshot Heath. Easthampstead. 



Sandhurst. Ambarrow. Near Jouldern's Ford. Long Moor. 



Broadmoor. Wokingham. Bracknell. Ascot. Windsor Great 



Park. Stubbing's Heath. BowseyHill. Windsor Park. 



A common plant of the heathy portions of the southern part of the 



county, but from the rarity of this ground in the north necessarily 



much less frequent in the Isis and Ock districts. 



The white-flowered form is rare. I have seen it at Shippon, in 

 Windsor Great Park, at Bracknell, &c. 



P. sylvatica occurs in all the bordering counties. 



RHINANTHUS, Linn. Gen. n. 658 {EJephas, Tourn. Inst. t. 482).

 Top. Bot. 292. Syme, E. B. vi. 180, t. 998. Nyman, 552. Fl. Oxf. 221. 

 Native. Pratal and pascual. Meadows, pastures, heaths, abundant. 



A. May- July. 

 First record. R. Crista-galU with Uredo Rhinmithacearum {Coleosporium 

 eiqyhrasiae, Schum.) about Oxford, Baxt. Phacn. Bot. 259, 1839. 



The Yellow Battle is semi-parasitic upon the roots of gras&es, and 

 in dry seasons much retards the growth of grass crops ; it is erratic in 

 its occurrence, being abundant in a field one season and rare or absent 

 from it in the next, and one field may be full of it while the adjoin- 

 ing one may be free. I suspect that this may be the Meadow Cow- 

 wheat of Dr. Noehden, in Mavor's Agr. Berks, 1809, 



Var. FALi-AiL — Alectorolophns minor, var. fallax, Wimm. et Grab. Fl. 

 Siles. ii. 213. In wet spongy meadows, such as tho.se of the Upper 

 Thames near Wytham and Binsey, and in the Lower Thames near 

 Kennington, Radley, Moulsford, Hurley, &c., this variety is frequent. 



Var. ANGUSTiFOLius (Koch, Syn. Fl. Germ. 544, 1837), sub R. minor, 

 Ehrh. (not of Gmel. Fl. Bad. ii. 669\ Near Newbury and in other 

 places I have gathered a narrow-leaved plant which I think must be 

 referred to this form, which is frequent in Scotland. 



Rhinanthus Crista-gaUi is found in all the bordering counties. 



MEL AMPYR UM, Linn. Gen. n. 660 (Tournefort, Inst. t. 78). 



[M. cRisTATUM, Linn. Sp. PL 605 (1753). Crested Cow-wheat. 



Syme, E. B. vi. 183, t. locx). 



The plant recorded under the above name by Dr. Noehden, from woods, 

 &c., in Mavor's Agr. Berks, 1809, is an error for M. pratense, which is our 

 woodland plant. 



Recorded on dubious authority for South Hants and Bucks.]
