GENERA AND SPECIES, 
ARRANGED ACCORDING TO THE FOURTH EDITION OF 
® foutott Catitlogue. 
ORDER I. RANUNCULACEiE. 
CLEMATIS. 
1. C. Vitalba, Linn. Denizen. English. 
Perhaps indigenous in hedges near Whitby — Rev. A. Bloxam. 
Naturalised on the green, Richmond — James Ward. “ Really wild,” 
in a hedge at the bottom of a wood on the margin of Guisborough 
moor, below the Warren, three quarters of a mile S.S.E. of Guis- 
borough, and nearly that from any house — William Mudd, 1854. 
This species might perhaps be placed in the native category without 
much risk of error, but has not yet been ascertained to occur in the 
chalk district of the south-east of Yorkshire. 
THALICTKUM. 
2. T. alpinum, Linn. Native. Highland. 
3. T. minus, Linn. Native. Scottish. 
A glaucous and glandular variety of this species (T. pubescens, 
Schreb.) is plentiful amongst the sand hills about Coatham, Redcar, 
and Marske (Vide Phytologist, vol. iv. page 933.) Probably it is the 
ordinary littoral form of the species. 
3. * T. flexuosum, Reich. Native. Scottish. 
Malham Cove, near Settle! — J. Dugdale. Bolton Woods, Wharf- 
dale ! — O. Lord. Mackershaw Woods, near Ripon — T. Simpson. 
Bank of the Tees, below Holwick and Wince Bridge, plentiful. 
Banks of the Wharf, at Thorparch. Probably T. majus of the Flora 
is wholly, or in greater part, identical with this species. 
4. T. flavum, Linn. Native. English.
