338 MR. H. W. PUGSLEY : A REVISION OF THE 
facile distinguenda est, in Algeria rupes caleiferas prope urbem Constantinam 
et forsan alios locos habitat. 
Pomel is here followed in restricting the Fumaria numidica of Cosson, 
which includes several distinct plants collected in different Algerian stations, 
to the form growing in the neighbourhood of Constantine, the first locality 
cited by Cosson in his original diagnosis of F. numidica. 
There is a flowerless specimen of this plant in Herb. Kew, collected by 
Bové at Constantine in September, 1859, in which the leaves are more than 
25 em. in length.

Rupicapnos perennis, eaudice brevi crasso ramoso decumbente tandem 
vestigiis petiolorum emarcidorum donato atque caulibus brevissimis vel fere 
nullis pr:edita. Volia pleraque radicalia, crassa, plus minusve glauca, cum 
petiolo 5-10 em. longa, longe petiolata, oblonga vel ovalia, foliolis (2-3- 
paribus) satis confertis, breviter petiolatis vel supremis subsessilibus, et 
segmentis secundariis in lacinias subdivaricatas oblongas obtusas obscure 
mucronatas vel acutinsculas irregulariter fissis 2-3-pinnatisecta. Racemi 
subeorymbiformes, meu/ti-(15-30-) fori, pedunculis paulo breviores, cum 
pedunculo (ad Sem. longo) folia sulerquantes vel in formis umbrosis breviores. 
Bracter 1-175 mm. longi, lanceolata, acute vel acuminatie, parce serrulata; 
pedicelli fructiferi graciles (Fere filiformes), anguste clavati, apice incrassati, 
flexuosi, infimi usque ad 25 mm. longi. Sepala 1-15 mm. longa, ‘5-1 nun. 
lata, ovalia vel ovata, peltata, subacuta, plus minusve crenato-dentata, nervo 
dorsali viridiusculo albida. Corolla parva, 4-5 mm. longa, haud gracilis, 
preter carinas virescentes albida; petalo superiore apice marginibus latius- 
culis patentibus anguste obovato. obtusissimo vel etiam retuso, calcare satis 
longo adscendente paululum curvato ; petalo inferiore lato marginibus latis 
patentibus apice sensim dilatato cuneuto-obovato obtusissimo (apice quam 
petalum superius paulo latiore), bast Laud saccato ; petalis interioribus fere 
rectis apice vix coalitis alâ laté lutescente proesertim ad apicem dilatatà inter
