Ranunculus acris, L., var. vulgatus (R. vulgatus, Jord.). * Primrose Hill, 
Middlesex.” —J. L. Warren. The on form of R. acris about 
London is, according to my experience, R. tomophyllus, Jord. ; but Mr. 
Warren’s specimens have the elongated horizontal rhizome and the broader 
leaf-segments of R. vulgatus, Jord. 
is, L., var. Boreanus (R. Boræanus, Jord.). “ Under a roċk, in 
ar D D. 
Boreanus. The root-stock is quite vertical the base of the stems 
glabrous, the petioles thinly clothed with adpressed hairs, and the 
leaves are deeply cut into very narrow segments. The flowers are very 
much smaller than in French specimens of R. Boreanus, being scarcely 
ret an inch across, and the whole stem little more than six inches 
` Caltha palustris, L., var. Guerangerii. “ Between the paper-mills and 
West Moulsey, Surrey.” —H. C. Watson. A specimen in flower, and one - 
L rmer with very narrow sepals, and the latter with gradually- 
acuminate longly-beaked follicles, are very characteristic examples of this 
form. From the same ocality Mr. Watson sends equally characteristic 
examples, in flower and fruit, of the typical C. palustris.

Actea spicata, L, « This species grows here, in Liley Wood, about 
five miles from Huddersfield, in considerable abundance, covering an area 
= about 250 to 300 square yards. Though I cannot look upon it as a 
truly native species, particularly as we have not a particle of limestone
