8o POLYGALACEAE 



are found, almost to the exclusion of the plants with larger flowers. 

 In the Pang and on the chalky parts of the Kennet and Loddon the 

 larger- flowered plants are almost as common as the small-flowered 

 forms. Casual specimens of the cultivated var. hotiensis, DC, Prod. i. 

 303 1824), are sometimes seen about houses and railway stations, as at 

 Wellington College Station, Shrivenham, Twyford, &c. The petals of 

 this form rapidly diminish in size when left to run wild (var. degener, 

 DC, 1. c), which I have seen on waste ground at Grandpont, at 

 Shrivenham, &c. 



V. tricolor is found in all the bordering counties. 



POLYGALACEAE, Reiclib. Consp. 120 (1828). 

 POLY GALA, Linn. Gen. n. 761 (Tournefort, Inst. t. 79). 

 P. vulgaris, Linn. Sp. PI. 702 (1753). Milkwort. 

 Top. Bot. 60. Syme, E. B. ii. 35, t. 185. Nyman, 83. PI. Oxf. 45. 



Native. Pascual. Calcareous pastures, boggy places, hedge-banks, 



grassy chalk-slopes, &e. Locally common. P. May-July. 

 First record. P. vulgaris. Heaths and pastures, Dr. Noehden, Maror's 

 Agr. Berks, 1809. 

 This, however, probably refers to P. serpyllacea, not to restricted P. vul- 

 garis. It is more probable that the record by Mr. G. G. Mill, in the 

 Phyt. i. (1843) 984, refers to the latter. 



1. Isis. Field near Appleton. 



2. Oct. Cothill. Marcham. In the Kifle Butt valley beyond 



South Hinksey. Uflfington. Upton, &c. 



3. Pang. Streatley, Pamplin. Ashampstead. Ashridge Wood. 



Tilehurst. Unwell Wood. Basildon. Hampstead Norris. 

 Compton. 



4. Kennet. Mortimer, Tufnail. Benham. Very abundant in 



meadows near Newbury. Near Inkpen. Woodhay. 



5. Loddon. Abundant on the chalk at Marlow, Mill. Bisham. 



Hurley. Cookham. Near Park Place. 



In the Report of London Bot. Exch. Club, 1867, Mr. H. C Watson records 

 P. ciliata, Lebel, as occurring at Compton. He says it is a variety of eu- 

 vulgaris, but Lebel's P. ciliata is now referred to P. serpyllacea. Perhaps 

 the Compton plant [? Berks] was only a ciliate form of P. vxdgaris. 



P. vidgaris varies with bright magenta, pink, pale blue, dark blue, 

 and rarely white flowers. It occurs in all the bordering counties.

Oxfordshire, Wilts, and Hants are the only counties which border Berk- 

 shire from •which I have records. It is very likely to be found in Berkshire.].
