FUMARIA 39 



Top. Bot. 27. Syme, E. B. i. 113, t. 77. Nyman, 28. Fl. Oxf. 22. 

 Colonist. Agrestal. Cultivated fields and waste ground. Very rare. 



A. August-September. 

 First record. Lowbury, the Author, in Rep. of Bot. Rec. Club for 1881. 



2. Ock. Fields near Lowbury Hill. 



3. Pang. Fields between Lowbury Hill and Unwell Road. Between 



Streatley and Pangbourn. 



The flatter leaflets and the fruit, rounded not pointed at the top 

 when mature, are the chief features distinguishing it from F. parxijlora, 

 of which Syme made it a sub-species, but Haussknecht, Willkomm, 

 and Lange consider it to be distinct. 



The specific name was given in honour of Vaillant, the author of 

 Botanicon Parisiense, the friend and correspondent of Sherard. The 

 Oxford Herbai-ium contains many of Vaillant's plants which were 

 bequeathed by Sherard. 



It is not recorded for Bucks, Wilts, or East Gloucestershire. 



P. parviflora, Lam. Enc. Meth. ii. 567 (1786). 

 F. tenui/olia, Symons, Syn. 200, not of Roth. 

 Top. Bot. 27. Syme, E. B. i. 114, t. 78. Nyman, 28. Fl. Oxf. 22. 

 Colonist. Agrestal. Cultivated fields on the Lower Chalk. Rare. 



A. June-September. 

 First record. The Author in Rep. of Bot. Rec. Club for 1881. See also 



Rep. Bot. Exch Club for 1881 and 1888. 



2. Ock. Field near Lowbury. 



3. Pang. Near Streatley. Field near Unwell Wood. 



4. Eennet. In a high chalky field above Hoe Benham, Miss Bowen. 

 This plant is much more glaucous than any other British Fumaria ; 



a bare chalk field, in which this was the prevailing plant in 1892, 

 looked at a distance as if a bluish-white smoke was overhanging it. 

 I suspect that our plant from these dry chalk fields would be called 

 var. erecta by Haussknecht. See Flora (1873), 460. 



The two latter species appear to be confined to the Lower Chalk 

 formations in Oxfordshire and Berkshire. F. parviflora, which occurs 

 also in Bucks and Hants, is not recorded for Wilts or East Gloucester- 

 shire. 



This order is included in Papaveraceae by Bentham and Hooker.
