14 FLORA OF OXFORDSHIRE. 
executed. It is rendered extremely boggy by the continual oozing of the 
water through its banks, and in lieu of meadow grasses of the best quality, 
with which it abounded, it is now over-run by Caltha palustris and 
other aquatic plants. Agric. Rep. of Oxford, p. 207. 
A double-flowered form has been found at Kirtlington, where the plant 
is unusually fine, by the Cherwell, under Gibraltar rocks, and also at 
Marcham, Berks. The plant varies extremely in leaf cutting, from 
roundly crenate to acutely serrate. A plant with a creeping rootstock 
was noticed in Ditchley Woods, and Baxter says he has found ‘a small 
variety with more reclining stems, each bearing only one to three flowers, 
with petals only about half-size of the common one, in boggy places at 
Stow Wood.’ 
Caltha forms one of the great’ adornments of our meadows in early 
spring.
