GENERA FUMARIA AND RUPICAPNOS. 351 
Stylus malleiformis. Fructis magni, sine mucrone 3-3:25 mm. longi, 2'5- 
2:15 mm. lati, ovali-obovati, eum mucrone conspicuo obtusissimi et inferne multo 
angustati (supra medium latissimi), plane compressi et valde carinati, siccitate 
omnino grosse tuberculato-rugosi. 
Hee species foliorum lobos latos et flores pallide purpureos R. Pomeliane 
habet sed braeteis sepalisque multo angustioribus, petali superioris ealcare 
subduplo longiore et fructibus plane longioribus satis differre videtur. 
R. oranensis vicinitatem oppidi Oran, Nedromam, Tlemcen ut videtur, et 
probabiliter alios locos in parte septentrionali provincia Oranensis Algerire 
habitat. 
This plant, which is better represented in the herbaria consulted than any 
other member of the genus, is rather inexplicably unnoticed by Pomel, unless 
it is intended to he included with the previous species X. Pomeliana, as may 
perhaps be inferred from the localities cited. It is not easy to adopt this 
view, however, seeing how clearly Pomel’s description accords with the 
features of the Garrouban plant in Herb. Mus. Paris and how widely it 
differs in severai particulars from œR. oranensis. On the other hand, as 
already remarked under R. Pomeliana, it seems impossible that Pomel was 
unacquainted with this plant in the neighbourhood of Oran. 
In shaded situations the foliage of X. oranensis becomes lax with relatively 
thin leaflets, somewhat acutely and by comparison narrowly lobed, while its 
flowers tend to be reduced in size, with no upward recurving of the margins 
of the upper petal, and a shorter, straighter spur. These features may be 
seen in some of the specimens sent out by Balansa, by Bourgeau, and by 
Faure. Munby's plants, on the other hand, are mostly very dwarf examples, 
probably collected in dry and exposed rock-fissures, and their clusters of 
well-developed flowers almost equal the much reduced leaves, of which the 
segments are thick in texture and very small. 
Judging from exsiecata, the flowers of R. oranensis appear to be of a paler 
purple colour than those of Æ. Pomeliana, and they are less concolorous, the 
margins of the upper petal being sometimes distinctly flushed with a deeper 
tint, recalling the coloration of the flowers of Fumaria agraria. 
There is a specimen of this plant at Kew from Munby’s herbarium, associ- 
ated with another which may be X. speciosa and labelled: Tlemcen,” but it 
appears uncertain from the arrangement of other examples on the sheet 
whether it really came from this habitat or whether a transposition of 
specimens has not at some time taken place.
