30 THE GENUS FUMARIA IN BRITAIN 



is even possible that further investigation may render its hybridity 

 altogether doubtful. In these circumstance I propose to describe 

 the plant as a presumable hybrid, and name it after Mr. Painter, 

 the original collector. 



If this assumption be correct, there can be no doubt that 

 one of the parents is F. officinalis, this species being equally 

 traceable in the narrow, laciniate sepals, the spathulate lower 

 petal, and the almost retuse fruits. The other factor I believe 

 to be F. Borcei, but it is just possible that it is really F. j^mrpicrea, 

 a species which grows to my knowledge in several places in 

 Shropshire. I place the plant as a hybrid after F. Borcei, however, 

 with very little hesitation, as it exhibits but scant traces of the 

 features characteristic of the Capreolatce, and, when considered in 

 all its points, can certainly only stand among the murales. 



The description of this plant is as follows, viz. : — 



FuMARiA Painteri, nova hybrida. 



F. officinalis L. x F. Borcei Jord, ? 



Fumaria annua ramosa, habitu rohusto et scandente. Folia 

 2-3 pinnatisecta, foliolis planis, in lobos oblongos mucronatos vel 

 lanceolatos acutos quam in F. Borcei paulo angustiores fissis. 

 Bacemi laxiusculi, multiflori (circa 20-fiori), 'pedunculos brevius- 

 culos superantes. Bractece lineari-lanceolatae, acuminatae, pecli- 

 cellos fructiferos erecto-patentes rectos vel paulo flexuosos apice 

 satis incrassatos suhcequantes. Sepala 3-3|- nwi. longa, 1^ mm. lata, 

 ovato-lanceolata, acuminata, peltata, inferne laciniata vel irregu- 

 lariter dentata, sed apicem versus integriuscula, praeter nervum 

 dorsalem viridiusculum albida. Corolla 10-11 mm. longa, pallide 

 rosea ; petalo superiore dorsum compresso, ohtuso vel apiculato, 

 alls atropurpureis tandem reflexis carinam excedentibus et apicem 

 subtruncatum attingentibus spathulato ; petalo inferiore margini- 

 bus angustis sed patulis et superne paulo dilatatis sub spathulato ; 

 petalis interioribus sursum curvatis apice atropurpureis. Fructtcs 

 mecliocres, 2| mm. longi ac lati, subrotundo-quadrati, cum apiculo 

 brevi sed persistente truncati vel etiam subemarginati, paulo com- 

 pressi sed obscure carinati, in stipitem obscurum pedicelli apicem 

 subaequantem breviter angustati, siccitate apicis foveolis obscuris 

 sed latiusculis leviter rugulosi. 



A plant of robust and rampant habit, considerably branched. 

 Leaves 2-3 pinnatisect, with flat leaflets cut into oblong or 

 lanceolate, mucronate or acute lobes, rather narrower than those 

 of F. Borcei. Bacemes rather lax, many- (about twenty) floivered, 

 exceeding the rather short peduncles. Bracts linear-lanceolate, 

 acuminate, nearly equalling the fruiting pedicels, which are erect- 

 spreading, straight or somewhat flexuous, and moderately thick- 

 ened at the apex. Sepals 3-3| mm. long, 1| mm. broad, ovate- 

 lanceolate, acuminate, peltate, laciniate or irregularly dentate in 

 the low^er half but becoming entire towards the apex, whitish in 

 colour, with green median line. Corolla IQ-llmm. long, pale pink in 

 colour, with the tip of the inner petals and wings of the upper one 

 blackish red. Upper petal dorsally compressed, obtuse or apicu-
