THE GENUS FUMARIA IN BRITAIN 35 



moral, in the province of Estremadura, and Calatayud, in Aragon ; 

 but it is highly probable that it will be found in other districts in 

 that country. 



In Britain its one certain habitat is Gilly Tresamble, in West 

 Cornwall, where I have supposed it to be an introduced plant which, 

 I am afraid, may be easily exterminated. A fragmentary specimen 

 in my herbarium without any fruit, received with F. Bastardi and 

 labelled " Sleeveen, near Middleton, Co. Cork. Comm. Miss 

 Knowles, Oct. 1906," may, however, belong to this species, and if 

 its occurrence as an established form in the county of Cork is 

 confirmed, a reconsideration of its status in Cornwall may become 

 necessary."

5. FuMARiA Bastardi Boreau. 

 The Fumitory to be discussed under this name appears to have 

 been first distinguished in Britain by Mitten, who published in 



[* Since the above account of this plant was written, statements have 

 appeared in the Reports of the two Botanical Exchange Clubs that it has been 

 identified by Professors Schinz, Ascherson, and Griibner, and by Dr. Fedde, 

 as Fumaria major Badarro— a determination which leads me to think that these 

 botanists can never have really examined it. 



As has been shown, F. paradoxa clearly belongs, both by the form of its 

 flowers and its fruit, to the subsection Media-, of the genus, while F. major, by 

 the common consent of authors, is one of the most characteristic species of the 

 Agrarics. In the original description of F. major (Badarro in Moretti, Bot. 

 Ital. p. 10 (1826)) the ^^fmj-irt type of lower petal is alluded to (" petalo in- 

 feriore lineari, apicespathulato-dilatato "), and by Parlatore, Hammar, Haussk- 

 necht, Rouy and Foucaud, and Nicotra alike, the plant has been closely asso- 

 ciated with F. agraria Lagasca, whose features have served as a type for a 

 section or subsection of the genus. 



F. major, of which there is good material both at Kew and in Herb. Brit. 

 Mus., may be contrasted with F. paradoxa thus :— 



F. major. F. paradoxa. 



Habit very robust. Habit less robust, with broader leaf- 

 segments. 



Racemes rarely more than 12 flowered. Racemes usually 15-20 flowered. 



Bracts acuminate, subequalling the Bracts broader, cuspidate, ^-g as long 

 much thickened, suberect fruiting as the rather slender, erect-spread- 

 pedicels, ing fruiting pedicels. 



Sepals about 3 mm. long and li mm. Sepals about 4 mm. long and 2 mm. 



broad, ovate-lanceolate, acuminate, broad, oval, acute, subentire. 

 incise-dentate below. 



Corolla 12-14 mm. long, with obtuse Corolla 11-13 mm. long, with subacute 



and broadly winged upper petal. and less broadly winged upper petal. 



Lower petal with broad, subspathulate. Lower petal with very narrow, spread- 

 spreading margins. ing margins. 



Fruit large, subrotund-obovate, very Fruit of moderate size, subrotund, 



obtuse, shortly mucronate, when dry generally subacute, when dry smooth 



densely tubercular-rugose. or finely rugulose. 



It is perhaps a curious coincidence that Hammar, when describing in his 

 monograph F. affi,ais, which may be regarded as intermediate in its characters 

 between F. major and F. paradoxa, specially warns his readers against confound- 

 ing it with the superficially similar F. major.]
