272 MR. H. W. PUGSLEY: À REVISION OF THE 
Tt is not always easy, in the absence of adequate material and a knowledge 
of the habitats, to justly estimate the value of the differences presented by 
this widely distributed and variable species. 
With regard to the geographical distribution shown at pp. 10 and 11 of 
* Fumaria in Britain,” the correctness of the habitats, Canaries and 
St. Helena, given both by Hammar and Haussknecht, may be doubted, the 
plants intended being probably F. coccinea and F. muralis respectively.

Fumaria F. capreolate habitu foliisque et pedunculis longis racemos densos 
superantibus.  Bractew pedicellos Jructiferos arcuato-recurvos subequantes. 
Sepala circa 3*5 mm. longa et 2 mm. lata, ovata, peltata, acuminata, denticulata, 
albida. Corolla 10-12 mm. longa, omnino rosea, ut videtur, aut roseo-albida ; 
petalo superiore angusto acuto alis roseis carinam haud superantibus preedito ; 
petalo inferiore marginibus angustissimis erectis acuto. — Fruetüs parri, 
2:25 mm. longi et 2 mm. lati, subrotundi, ad medium latissimi, superne in 
apicem subacutum et inferne in stipitem quam pedicelli apex angustiorem 
æqualiter angustati, juniores plane apiculati, siccitate apicis foveolis parvis 
distinctis rugulosi. 
Descriptio secundum exemplar solum imperfectum in Herb. Boissier. 
In montibus Algeriæ habitat. 
Hae Fumaria que ut species nova dubitanter descripta est, per sepala 
minora denticulata, per petali superioris alas roseas nec purpureas, et 
præsertim per fructůs subacutos rugulosos a F. capreolatd, ut videtur, specifice 
differt. 
Secundum cl. Haussknecht hujus plantæ fructus rugulosus transitum ad 
F. flabellatam denotat, sed, me judice, et fructus rugulosus subacutus et 
corolla angusta sine apice purpureo rosea affinitatem cum F., coccined 
monstrant. 
The specific name intermedia having been already appropriated under the 
genus Fumaria (Withering, Arr. ed. 3, iii. 620, t. 29 (1796)) to represent a 
plant now referred to Corydalis bulbosa, DC., the present form has been 
described as F. dubia.
