 This plant appears to be confined to the arable fields on the chalk in 

 Berkshire, where it is found on King Standing Hill at an elevation of 

 400 feet. Sometimes F. officinalis grows with it, but no intermediate 

 forms have been observed by me. (The authors of the Herefordshire 

 Flora record intermediate plants.) F. densiflora may readily be known 

 from F. officinalis by the large sepals and the sub-globose fruit ; 

 the leaves, especially in the young state, are also different, being 

 usually of a yellower-green in colour and thicker in the texture, but 

 the differences, although manifest enough to the eye, are not easily 

 described. East Gloucestershire is the only bordering county from 

 which F. densiflora is not recorded.

 First record. F. officinalis. Gardens, cornfields, Mavor's Agr. Berks, 

 p. 256, 1809. 



Boreau points out that the early flowering plants have larger and 

 more brightly-coloured flowers than those which bloom later in the year. 



Var. DENSIFLORA, Grou. and Godr. Fl. Fr. i. 68 (F. densiflora, Pari. Mon. 

 not of DC, Cat. Monsp.), a form which occurs in dry chalky fields, 

 has more compact spikes and smaller leaves of a more fleshy texture. 



Var. scANDENS. See Lamotte, Fl. du Plateau, 69 (1877% Reichb. Ic. 

 Fl. Germ, et Helv. iii. f. 4454, is an autumnal form often found in rich 

 garden ground or potato fields, and has a habit which approaches the 

 capreolate group in its rampant growth. It may be distinguished 

 from that section by the abrupt enlargement of the lip in the lower 

 petal. This form has been noticed about Abingdon, Reading, Twyford, 

 &c. A similar but much more glaucous plant occurs in garden ground 

 at Newbury ; specimens were sent to the Bot. Exch. Club in 1892. 



Fumaria officinalis is abundant in all the bordering counties.
