malleiformis lobis divaricatis (an semper ?). Fructüs maximi ad modici, 
sepius valde compressi, pericarpio quam in sectionibus sequentibus 
verisimiliter tenuiore preediti. 
RUPICAPNOS MURICARIA, Pomel, Nouv. Mat. Fl. Atlant. i. 245

(PI. 14, fig. 1.) 
Hasive, Chevallier, Pl. Saharze Alger. 1902, No. 397, Ghardaia, ut Fumaria 
longipes ! 
Rupicapnos, ut videtur, annua, radice longa et caule suberecto (4-8 em. 
alto) brevissime ramoso preedita. Cotyledones in statu foliaceo maxime, 
circa 4 em. longæ, lineari-oblanceolate, tenuiter acuminatie, diu persistentes. 
Folia caulina haud crassa, omnia longissime petiolata, eum petiolo 5-7°5 em. 
longa, deltoidea, foliolis subtrifidis longiuscule petiolatis et segmentis 
secundariis in lacinias parvas oblongas vel lanceolatas longe mucronatas vel 
fere aristatas irregulariter multifidis trisecta. Racemi corymbiformes, pauci- 
(2-5-) flori, brevissime pedunculati vel subsessiles, foliis plus duplo breviores. 
Bractew 1-2 mm. longæ, subulate, tenuiter acuminatze ; pedicelli Jructiferi 
filiformes, apice vix inerassati, flexuosi, ad 15 mm. longi. Sepala parva, 
circa 1 mm. longa, ‘5—6 mm. lata, ovata vel lanceolata, vix peltata, acuta, 
parce dentata vel subintegra, albida. Corolla 7-8 mm. longa, preeter carinas 
virides alba vel leviter roseo-tineta ; petalo superiore apice marginibus 
latiusculis subpatentibus anguste oblongo, truncato obtusissimo vel etiam retuso, 
caleare gracili longo deflexo, [nectario flexuoso longissimo ap. Pomel]; 
petalo inferiore apice marginibus latiusculis patentibus spathulato, obtusissimo, 
basi verisimiliter obscure saccato; petalis interioribus paulo sursum curvatis 
apice plane alatis atropurpureis. Stylus malleiformis. Fructis maximi, sine 
rostro 2°75-3 mm. longi et 3-3°25 mm. lati, subrotundi sed latiores quam 
longi, cum rostro magno 1:5-2 mm. longo quadrangulato-subulato obtusissimi 
et inferne subtruncati, valde compressi et acute carinati, pericarpio satis 
tenui priediti, in sicco (sine apicis foveolis) carinam versus subregulariter 
grosse et acute tuberculato-rugosi vel muricati, infra rostrum et ad fructüs 
medium vix tuberculati. 
Hee Rupicapnos distinetissima per folia trisecta, per racemos corymbi- 
formes subsessiles paucifloros et prsesertim per fructüs maximos grosse 
rostratos carinam versus muricatos ab generis omnibus aliis speciebus facile 
dignoscitur. 
R. muricaria Metlili (ap. Pomel), Ghardaiam et forsan alios locos in 
regione Sahare Algeriensis habitat, ubi in fissuris rupium crescit. 
This species is unique in the genus on account of its trisect leaves, its 
subsessile, 2-5-flowered corymbs, and its very large, long-beaked fruits, 
muricate only towards their margins. Chevallier’s exsiccata, which form the 
basis of the foregoing description and from which the accompanying plate is
