GENERA FUMARIA AND RUPICAPNOS. SoD 
6-8 mm. longa, alba ; petalo superiore apice marginibus latis subpatentibus 
ultra carine apicem productis obovato-oblongo, truncato vel retuso, 
carinà crass, viridi vel purpurascente, calcare longiusculo | deflexo ; 
petalo inferiore (quam superius latiore) apice marginibus latis patentibus in 
limbum suborbicularem obtusissimum vel retusum abrupte dilatatis et carina 
viridi predito, basi subsaccato ; petalis interioribus fere rectis apice plane 
alatis atropurpureis. — Fructüs maximi, sine rostro 3:5 mm, longi, 3 mm. lati, 
subrhomboidel, cum rostro magno (1 mm. longo), latissimo, striato, quadrangu- 
lato, compresso subacuti et inferne attenuati, conspicue compressi et acute 
carinati, pericarpio satis tenui præditi, siccitate preter rostrum. omnino 
grosse et acute tuberculato-rugosi vel muricati. 
R. longipes in fissuris umbrosis rupium ad Mnechounés, prope Biskram, ad 
Elkantaram (Cosson) et in Montium Aurasiorum regione montaná inferiore 
prope Beni Souik (Cosson) in provincià Constantinà Algeriw invenitur. 
This species was originally described by Cosson & Durieu (l. c.) as a 
Fumaria, and was founded on exsiecata collected by Balansa near Biskra and 
by Gallerand near Beni Souik, both in the southern part of the province of 
Constantine. The annual nature of the plant and its floral characters were 
defined in the original description, but no mention was made of its peculiar 
fruit ; and later, in the Compendium, it was reduced by Cosson to a variety 
of his perennial F. numidica. Pomel admitted it as a species, although the 
actual plant was unknown to him. 
The sheet of Balansa’s Biskra plant named Fumaria longipes in Herb. 
Mus. Paris contains four specimens, two of which agree with Cosson’s 
diagnosis, so far as it goes, and possess the remarkable fruit described above. 
From these the foregoing deseription and the accompanying figure have 
been taken. The other two specimens, which are not alike, possess some- 
what similar foliage but are clearly shown by their widely different fruits to 
be specifically distinct. These are separated under the names of X. preter- 
missa and R. sublevis.
