GENERA FUMARIA AND RUPICAPNOS. 251 
From these considerations, morphological and geographical, it has been 
decided to follow Haussknecht in dividing the genus into two Sections, 
Latisecte or Grandiffora, and. Angustisecte or Parviffora, based mainly on a 
combination of foliar and floral characters, as has been done in “ Fumaria in 
Britain." 
The Section Grandiflora, representing the Agrarie and Capreolatw of 
Hammar, is readily subdivided into three subsections, as is done by Hauss- 
knecht, by eliminating, as Murales, from the well-marked Agrarian and 
Capreolate species the more dubious and intermediate plants, some of which 
present distinct individual features, while one or two others show affinities 
with certain of the Parviflore. 
Of the Section Parviflora (Oficinales of Hammar) the most strongly 
marked species are F. parviflora, Lam. and its allies, which were distinguished 
in “ Fumaria in Britain? as Microsepale from their very small sepals. Among 
the other species, F. officinalis with some allied forms seems to constitute a 
natural subsection (Uficinales) owing to the peculiarly shaped and broad 
fruits, as well as the larger flowers with less minute sepals. The remaining 
species—all well-marked by relatively large sepals—fall into a homogeneous 
subsection Latisepale. In these plants the form of the corolla is less 
characteristic than in the other Parviflore, and some of them show afiinities 
with a few species of the Murales. 
With regard to the generic sequence of these subdivisions, the most natural 
arrangement appears to be a commencement with the subsection Agraria, 
followed by the Capreolate and the Murales respectively. As the Murales 
show affinities with the Latisepale these subsections are placed in juxta- 
position, and after them the Offcinales, with the Microsepalæ, comprising the 
most extreme small-flowered forms, completing the genus. 
SPECIES OF FUMARIA AND THEIR DISTRIBUTION. 
The number of species of Fumaria recognized in this Revision is 46— 
27 Grandiflore and 19 Parviflore,  Hammar's number of species in his final 
monograph is 24, including F. Heldreichit but without F. corymbosa ; and 
Haussknecht gives 35, if F. microstachys and F. microcarpa are included, 
Twenty of Hammar's species are retained, three of the remainder, F. affinis, 
F. vagans, and F. Gussonei, being united with F. media B. confusa as one 
species F. Bastardii, and F. Heldreichii is reduced to a variety of F. Thuretii. 
Of Haussknechvs species F. gaditana and F. Pikermiana are made varieties 
of F. sepium and F. Thuretii respectively, and F. malacitana is identified 
with F. macrosepala ; the remaining 32 retain their specific rank excepting 
F. Borwi, which is reduced to a subspecies of F. muralis. 
The 15 additional species are variously accounted for. F. Gaillardotii is 
segregated from the allied X. major, F. apiculata from F. muralis, and the 
Dalmatian F. Petteri from F. Thuretii. Haussknecht’s varieties F. capreola'a
