GENERA FUMARIA AND RUPICAPNOS. 349 
Rupicapnos perennis, glauca, caudice crassiusculo, ramoso, brevi vel paulo 
elongato, decumbente, tandem vestigiis petiolorum emarcidorum donato, 
caulibusque semper brevibus. Folia pleraque subradicalia, glauca, carnosa, 
10-20 em. longa (petiolo incluso), longe petiolata, oblonga, foliolis late 
obovatis breviter petiolatis et segmentis secundariis subimbricatis raro 
alternantibus in lobos rotundatos vel obovatos obtusos vix mucronulatos sæpe 
incisos irregulariter fissis. 2-pinnatisecta subquinata, Racemi corymbiformes, 
multi-(circa 20-) flori, cum pedunculo (ad 6 em. longo) foliis subduplo 
breviores. Bractew 2-275 mm. longe, late ovales, cuspidatz, apicem versus 
dentate ; pedicelli fructiferi graciles (fere filiformes), apice incrassati, 
flexuosi, infimi ad 25 mm. longi. Sepala 3-35 mm. longa, fere 3 mm. lata, 
suborbicularia (coroll tubo latiora), peltata vel cordata, breviter acuminata, 
presertim basin versus inciso-dentata, prseter nervum dorsalem latum rubi- 
cundum purpurascentia. Corolla magna, 12-14 mm. (15 mm. ap. Pomel) 
longa, plus minusve gracilis, pallide purpurea ; petalo superiore marginibus 
apice parum dilatatis subpatentibus vel deflexis (nonnunquam paulo sursum 
recurvatis) anguste oblongo obtuso, cariná viridiusculà petali apicem vix 
attingente, calcare brevissimo (2-3 mm. longo) rotundato curvato; petalo 
inferiore marginibus patentibus apicem versus vix dilatatis lineari-oblongo nec 
subspathulato, obtusiusculo, ad basin ipsam gibboso-saccato ; petalis interioribus 
sursum curvatis apice modice alatis atropurpureis. Fructús majusculi, sine 
mucrone 2:5-2:75 mm. longi ac lati, verisimiliter subrotundo-obovati (fere 
ovales ap. Pomel), cum mucrone brevi obtusissimi et inferne angustati, satis 
compressi et valde carinati, siccitate omnino grosse et elevato tuberculato- 
rugosi. 
Hæc planta per foliorum lobos latissimos rotundatos, per bracteas latis- 
simas atque per flores purpureos brevissime calcaratos sepalis suborbicularibus 
preeditos ab hujus gregis speciebus aliis specifice differre videtur. 
R. Pomeliana rupes ad Garrouban et forsan ad locos alios in provincia 
Oranensi Algerie habitat. 
This plant is identified by Pomel with the original Fumaria africana, 
Lamk. It has been shown, however, that the descriptions of Lamarck and 
Desfontaines can be definitely determined to refer to another species, albeit 
the name of F. africana was subsequently extended by Cosson to cover in an 
aggregate sense practically all the forms of the present section. As the 
specific epithet “ africana? must be retained for the form originally so 
described, and the plant so named by Pomel is distinet and has not been 
otherwise distinguished, a fresh epithet becomes necessary for the latter. It 
is therefore proposed to commemorate Pomel in its new name. 
It is noteworthy that while Pomel's diagnosis of this plant agrees well 
with the Garrouban exsiccata in Herb. Mus. Paris, the examples seen from 
other localities which he cites (Tlemcen, Nedroma, and Oran) show different 
characters and seem to belong to other species. Of these, the Oran plant
