THE GENUS FUMARIA L. IN BRITAIN, 

 By H. W. PUGSLEY, B.A. 



The following account of the British Fitmarice, written mainly 

 during the winter of 1910-11 but delayed in completion, is a con- 

 tinuation and summary of the papers published in the Journal of 

 Botany in 1902 (vol. xl. pp. 129 sqq.) on " The British Capreolate 

 Fumitories," and two years later (vol. xlii. pp. 217 sqq.) on 

 "A l^ew Fumaria." In the first of these articles it was shown 

 how an apparently endemic species, Fumaria imrpurea, had been 

 wrongly identified with F. Borcei Jordan, while the true plant had 

 become inextricably confused with that author's F. confusa and 

 the F. muralis of Sender. In the second paper the fine Cornish 

 Fumitory allied to the Spanish F. agraria Lagasca was described 

 as a new species, F. occidentalis. 



I regret it has not been possible for me to examine the 

 Fumaria material in the great Continental herbaria, but since the 

 publication of these papers the Fumitories in the majority of 

 British collections have passed under my observation, and various 

 botanists have made large gatherings in the field, with the result 

 that much fresh information has been accumulated, and some 

 entirely new forms discovered. Meanwhile, valuable additions 

 have been made to the general collection available for reference at 

 the British Museum. 



To describe these new forms and review the genus as repre- 

 sented in Britain in the light of recent work is a principal object 

 of the present paper. 



The earliest work devoted to the Fumitories, so far as I am 

 aware, is Handschuch's De Plantis Fumariaceis, published at 

 Erlangen in 1832, in which four species of Fumaria are described, 

 viz. F. capreolata L., F. officinalis L., F. Vaillantii Lois., and 

 F. parviflora Lam. A few years later these plants attracted the 

 notice of British botanists. In 1840 Babington read a paper 

 respecting them before the Botanical Society of London, and 

 Arnott published an independent account of the British forms in 

 the Proceedings of the Botanical Society of Edinburgh (pp. 99-108). 



In 1814 Parlatore produced a monograph of the Fumariacecs, 

 with descriptions of ten species of Fumaria, and in the years that 

 immediately followed a number of forms were described on the 

 Continent under fresh specific names — chiefly by Jordan, who 

 dealt with French plants, and Boissier, wliose specimens were 

 obtained from various countries bordering on the Mediterranean.
