INTRODUCTION. 
Ix the course of writing “The Genus Fumaria in Britain,’ 
Supplement I to the ‘Journal of Botany’ for 1912, it was found necessary to 
examine not only those Foreign Fumitories that were most closely connected 
with the British forms, but in a general way all the annual species of the 
genus of which material could be obtained ; and remarks on the 
features of various non-British species are embodied in that work 
reviews of the generic subdivisions. 
During the winter of 1912-13 several Foreign collections were received 
for examination, notably the fine sets of Mr. Charles Bailey and of Ziirich 
University, the latter kindly sent by Professor Schinz ; and with this 
material for reference (numbering over 2000 sheets), in addition to the 
herbaria at the British Museum and at Kew, where some important types 
are preserved, an opportunity presented itself to effect an appreciable advance 
in the study cf the genus. About the same time valuable supplies of living 
plants were obtained from the Riviera and the neighbourhood of Gibraltar 
through the kindness of Mr. H. Stuart Thompson, Major A. H. Wolley-Dod, 
and Mr. E. G. Baker, and an opportunity was take 
summer to visit the Doissier Herbarium at Geneva

The result of this work is the present paper, the completion of which has 
been seriously delayed owing to the pressure of other duties consequent upon 
the war. An attempt is now made to offer a general criticism of all the 
species of the genus, which it is thought may be useful for reference üs a

in Britain,’ and certain other works wherein the Fumarie are dealt with in 
more or less detail. Hammars earlier Monograph (* En Monografi öfver 
Slägtet Fumaria”), which was published at Lund in 1854 and considerably 
amended in his later work, is referred to only in a few special cases.
