26 ENGLISH BOTANY. 



base, stipules of all the leaves lyrate-pinuatifid ; petals shorter 

 than, or only equalling, the erect sepals. Capsule globular. 



A weed in cultivated ground. Very common and generally 

 distributed throughout Britain. 



England, Scotland, Ireland. Annual (occasionally Perennial). 

 Summer and Autumn. 



Stem usually stouter and more erect than that of V. eu- 

 tricolor. The whole plant paler green. The flowers smaller, ^ to 

 f inch across, with the lateral and lower petals forced forward from 

 the conniving of the four lower sepals. Petals white or yellowish- 

 wuite, the lower one with a yellow spot at the l)ase and 5 purple 

 lines. Fruit peduncles more divaricate than in V. eu-tricolor. 

 Capsule nearly globose, scarcely at all trigonous. 



I feel very great doubts whether this can be separated as a sub- 

 species from the larger form, but sown in a garden it shows no 

 tendency to pass into it. V. agrestis (Jord.), contempta (Jord.), 

 and segetaUs (Jord.), appear to belong to V. arvensis. The root 

 of this form not unfrequently lives through the winter, but does 

 not even then produce a subterranean branched rootstock, as in the 

 two following.

Rootstock branched, with the branches tufted, producing rather 

 short decumbent stems and short subterranean stolons. Stipules 

 of the lowest leaves digitate-pinnatifid. Petals equalling or a little 

 exceeding the sepals, spreading. Capsule oblong-ovoid, 3-sided. 



On sandy seashores. Ptare. In the West of England and in 

 Ireland ; Braunton Burrows, near Bideford, Devonshire; Llyn-Coron, 

 Anglcsea (with yellow flowers and small stipules) ; New Brighton, 

 Cheshire ; Portmarnock, near Dublin (with yellow, blue, and 

 purple flowers, and small stipules) ; and Mullaghmore, Sligo, wdth 

 yellow flowers and large stipules. Some of these forms probably 

 occur at the Land's End, Cornwall, and at Cromlyn Biu'rows, 

 Glamorgan ; but I have seen no specimens from these stations. 

 England, Ireland. Perennial. Summer and Aixtumn.
