68 THE GENUS FUMAEIA IN BRITAIN 



Eouy & Foucaud's Fl. de France — the most natural arrangement 

 on the whole, I think, albeit the two plants show considerable 

 difference at times in habit and foliage. 



Of F. Laggeri there are Zermatt examples from Lagger, both 

 at Kew and the British Museum, which are certainly small plants 

 of F. Schleicheri ; and of this species F. Laggeri is made a 

 synonym by Eouy & Foucaud. Haussknecht, on the contrary, 

 identifies F. Laggeri with F. Chavini, reducing the plant to a 

 variety Laggeri of F. Vaillantii, and quoting both specific names 

 in synonymy. But I cannot find that he gives any good reason 

 for this view, and he admits that Lagger sent out F. Schleicheri 

 as the plant in question ; and as Jordan's remarks, especially 

 those respecting the larger sepals and reflexed petal-wings, seem 

 to point to F. Schleicheri, I think that the author's description 

 and Bagger's specimens must be relied on, and agree with 

 Eouy & Foucaud in regarding F. Laggeri Jord. as identical with 

 F. Schleicheri. The confusion among these plants has apparently 

 arisen owing to both F. Schleicheri and F. Chavini occurring at 

 Zermatt, the locics classicus of F. Laggeri. I collected both of 

 these plants growing in company close to the village in the 

 summer of 1906. 



It may also be concluded from Hammar's description and the 

 absence of any allusion on his part to F. Schleicheri that his var. 

 Laggeri is likewise that species and not the same as F. Chavini, 

 and the earliest varietal name for the latter plant would therefore 

 appear to be F. Vaillantii v. Laggeri Haussk. Hammar and 

 Haussknecht thus designate two different plants by the same 

 varietal name, and as the latter author, moreover, identifies his 

 plant with F. Laggeri Jord., which I believe to be F. Schleicheri, 

 I consider that the name Laggeri, to represent a variety, should 

 be passed over altogether as one tending to confusion, and var. 

 Chavini Eouy & Foucaud adopted in its place. 



In addition to this plant Haussknecht establishes three other 

 varieties of F. Vaillantii, viz., y inclica, an Asiatic form approach- 

 ing F. parviflora in its finely divided foliage ; ^ Schrammii, de- 

 scribed from German specimens, but since found in France and 

 Spain and even in Asia ; and h conferta, a compact plant from Asia 

 Minor. He also distinguishes forms (four in number), which are 

 really states, as in F. parviflora and F. officinalis. 



The most interesting of these variations, as an European plant, 

 is var. Schrammii, which was first placed under F. imrviflora by 

 Ascherson in Verhand. des Bot. Vereins. Prov. Brandenburg, 

 p. 221 (1863). This is a very slender form, with paler flowers 

 than the type, short, slender pedicels, and smaller, less rugose fruits 

 with a persistent apiculus. Its foliage, to my eyes, resembles 

 that of var. Chavini, and I suspect there may be gradations 

 between the two varieties, as Haussknecht thought there were 

 between v. Chavini and the type. 



The variety Schrammii is maintained by Eouy & Foucaud, and 

 is shown also in Willkomm & Lange's Flora Hispanica. 



It is strange that, although specimens closely allied to these
