THE GENUS FUMARIA IN BRITAIN 63 



such plants as a variety acuminata, although I suspect that this 

 form passes at least into var. glauca. 



It will be noticed that, in adopting these varietal names, I do 

 not agree with Haussknecht in regarding all these plants, with 

 the exception of vars. segetalis, latisecta, and sinaitica, as simply 

 states of one species. Such a view seems to me untenable when 

 the variations of the fruit are considered, and moreover, so far as 

 my experience goes, the dwarf, extremely glaucous forms never 

 become truly rampant. 



Of plants like var. glauca, which is apparently a South 

 European form, I have seen no British examples, but the some- 

 what similar form described and figured in Eng. Bot. 590 is 

 perhaps our commonest form of the species. This agrees, so far 

 as can be seen, with the exsiccata, F. Schultz, Herb. Norm. 415 

 et bis, quoted by Clavaud for his var. c. acuminata, and I think, 

 judging also from his description and figure, that this name may 

 be safely adopted as representing a British plant. According to 

 the material I have seen, this variety is uncommon on the 

 Continent, and found chiefly towards the west, particularly in 

 Spain, France, and Germany. 



There also occur in several British localities plants approxi- 

 mating to the specific type as defined above, much laxer in habit 

 and less glaucous, with larger leaf-segments, whiter flowers, and 

 more globular and shortly pointed fruits. 



Furthermore, the Cambridge plant originally referred to F. 

 Vaillantii by Babington remains to be included. This form seems 

 intermediate between the type and var. glaiica in habit and 

 foliage, with the white flowers of the former and unusually long 

 sepals, rhomboidal in outline rather than ovate or orbicular. 

 But, as already indicated, it is chiefly distinguished by its fruits, 

 which, though shortly pointed when young, become obtuse at 

 maturity, and when dry, show the keel drawn into a very short, 

 blunt and notched beak, almost presenting the aspect of a minia- 

 ture caryopsis of F. occidentalis. The plant is no doubt closely 

 allied to Viviani's F. leucantha, but in all the herbarium specimens 

 that I have seen the distinctly notched fruit is constant, and 

 considering also its relatively large sepals and intermediate habit, 

 it seems desirable to give it varietal distinction. As it was first 

 correctly placed under F. parviflora by Syme it may be suitably 

 distinguished as var. Symei. 



It may be mentioned, as a curious coincidence, that this 

 species simulates F. occidentalis not only in one form of its fruits, 

 but in the usual coloration of its corolla, these being the only two 

 fumitories, I believe, in which the wings of the upper petal are 

 blotched externally with dark red with clear white margins.
