262 MR. H. W. PUGSLEY: A REVISION OF THE 
Specimens collected at Ronda by Mr. C. Bucknall in 1907 do not accord with 
Boissier’s diagnosis and seem indistinguishable from well-grown African 
examples. 
Haussknecht’s forms diffusa and umbrosa (Flora, l.c.) also appear to be 
shade-forms, and it may indeed be doubted whether Boissier’s original 
account of the species was taken from a normal plant. 
In well-grown individuals, the corolla of F. rupestris is pale pink, with an 
occasional suffusion of purple in the wings of the upper petal. When shade- 
grown, it becomes whitish, with the purple colour confined to the tips of the 
inner petals as in F. agraria. 
F. rupestris is remarkable among the Agrari for the narrowness of its 
corolla and the wings of the outer petals, and on this ground alone might be 
placed with almost equal propriety with the Murales near F. Bastardii, Its 
fruit, however, although not very large, is of markedly Agrarian form. 
F. rupestris var. maritima, Battandier in Bull. Soc. Bot. Fr. xxxii. 336 
(1885), is apparently referable to F. bicolor, Sommier.

Fumaria annua, ut videtur, habitu laxiusenlo et satis robusto. Folia pallide 
virentia, irregulariter. J-4-pinnatisecta, foliolis in lacinias parvas planas 
angustas lineari-oblongas acutas vel mueronatas fissis priedita. tacemi 
laxiusculi multifori (15-25-flori), pedunculos breves multo superantes. Bractew 
lineari-lanceolate, obscure serrate, tenuiter acuminate, pedicellis fructi- 
feris erecto-patentibus longiusculis apicem. versus modice incrassatis dimidio 
breviores, sed infime interdum paulo longiores. Sepala minima, circa 2 mm. 
longa, 1 mm. lata, oblonga, acuminata, obscure dentata, preter nervum 
angustum viridiusculum rosea, in fructu juniore persistentia. Corolla 
12-14 mm. longa, rosea, ut in F. rupestri angusta ; petalo superiore alis roseis 
reflexis carinam. vix superantibus sed apicem attingentibus et calcar tenue 
versus longe productis obtuso; petalo inferiore obtusiuseulo marginibus 
latiusculis patulis apicem attingentibus ; petalis interioribus sursum curvatis 
apice purpureis. Fructús modici, sine mucrone 2:5 mm. longi, 2 mm. lati, 
subrotundi, obsolete carinati, obtusiwseuli et persistenter grosse mueronati, 
inferne multo angustati, siccitate apicis foveolis obscuris sed latiuseulis 
dense sed tenuiter tuberculato-rugosi. 
Heee Fumaria distinetissima quie subsectionis Agrariarum flores fructüsque 
habet, per folia decomposita eis F. Avalikii et F. micranthe similia mirabilis 
est. Inter afħines F. rupestri proxima est, sed proeter foliorum differentiam 
bracteis brevioribus, sepalis minimis et fructibus minus rugosis, grosse 
mucronatis potius quam rostratis, facile distinguitur.
