GENERA FUMARIA AND RUPICAPNUS. 317 
light rose-coloured with very little, if any darker tinting in the wings of the 
upper petal. These wings, as well as the margins of the lower petal, are 
frequently more strongly developed than in the specific type. The fruit of 
var. Chavinii, besides being often rather larger and more rugose than in 
typical F. Vaillantii, differs further in being normally plainly longer than 
broad. 
There is good material of this variety at Kew from the locus classicus near 
Geneva. 
F. Vaillantiiy. ochroleuca, Knaf in Flora, xxix. 292 (1846), is probably, for 
the most part, a pale-flowered form of this variety. 
ô. venetica, var. nov. 
Crsiec. Fiori, Béguinot, Pampanini, Fl. Exsice. Ital. No. 565, Venetia, 
G. Rigo, ut F. Vaillantii! 
Planta glauca, ut in var. Chavinii robusta, et satis ramosa. Folia ampla, 
irregulariter 2-3-pinnatisecta, foliolis in lacinias confertas, lineari-lanceolatas 
vellineares, acutas fissis. Racemi densiusculi, multi-(sub-20-) flori, quam in 
typo paulo longius pedunculati. Bractew late, lineari-oblonge, cuspidate, 
pedicellis breviusculis (circa 2 mm. longis) erecto-patentibus paulo breviores. 
Sepala saltem 1 mm. longa, *50-"66 mm. lata, ovato-lanceolata, plus minusve 
serrata, nervo dorsali viridiusculo rosea aut roseo-albida, caduca. Corolla ut 
in var. Chavinii, sed petali superioris alis angustioribus obscure purpureis. 
Fructis plane latiores quam longi (2 mm. longi et 2:25 mm. lati), subtruncati, 
siccitate cum apicis foveolis latis rugosi. 
Hee varietas var. Chavinii proxima est, sed pedicellis brevioribus erecto- 
patentibus, bracteis sepalisque latioribus, corolla alis angustioribus obscurius 
colorata, fructibus multo latioribus distinguitur. 
F. officinalis var. Wirtgenii foliorum. segmentis latioribus, sepalis corollis 
fructibusque majoribus conspicue differt. 
F. Schleicheri pedicellis gracilioribus et multo longioribus, bracteis mini- 
mis, floribus saturate roseis petali superioris alis valde reflexis, fructibus 
apiculatis rugulosis plane recedit. 
F. Vaillantii var. venetica in cultis prope Torri del Benaco, Rivoli et 
Veronam in Venetia Italie septentrionalis habitat, ubi frequentissime a cl. 
Rigo ut F. Laggeri collecta est. Hæc planta non solum ut F. Laggeri et 
F. Vaillantii sed etiam sub nomine F. Schleicheri (Fiori, ete., Fl. Exsice. Ital. 
No. 566!) distributa est. Exemplar hujus varietatis, ut videtur, sub nomine 
F. Laggeri prope Weimar (Kastenberg) a Dr. Torge collectum in herbario 
Kewensi est. 
An element of doubt exists as to whether the above three varieties are best 
placed as such under F. Vaillantii, and further study of the group seems 
desirable, especially as the features of the floral organs can be readily 
mistaken owing to their small size.
