GENERA FUMARIA AND RUPICAPNOS. 323 
Forma Vivianii. 
F. leucantha, Viviani, Fl. Corsieze Sp. Nov. Diagn. 12 (1824) ; F. parviflora 
var. leucantha, Clavaud in Act. Soc. Linn. Bordeaux, xxxv. 4° sér. v. 276 
(1881), et Fl. Gironde, 52 (1882), ex parte. 
Eæsice. Pichler, Fl. Exsice. Austro-Hungarica, No. 87, Spalato, ut 
F. 4 arviflora! Reverchon, Pl. de Sardaigne, No. 91, ut F. parviflora (Ë. fol. 
laciniis latioribus) ! 
Fructibus.obtusis nec acuminatis nee emarginatis a typo differt. 
In the ease of this species Hammar’s diagnosis is generally accurate, but 
he appears to have overlooked the characteristie broad bracts, which he 
describes as linear, as well as the normally obtuse but not emarginate upper 
petal, with its purple bloteh on the outer or lower side of the wings. 
The form regarded as the specific type, in accordance with the general 
view of authors, is the more robust plant, wiih laxer and less glaucous 
foliage, whiter and somewhat narrowly winged corollas, and shortly 
mucronulate fruits, as described in “ Fumaria in Britain” (F. parviflora var. 
leucantha, Clavand, l.c., excl. forma Vivianii). The rotundate, ascending 
spur common to all the forms of the species is not mentioned, through 
inadvertence, in that description. It may be added that the leaves in this 
species are commonly 3-4 rather than 2—3-pinnatisect, and the corolla is not 
often more than 5 mm. in length. | 
Flores albi, vix roseo-tincti ; sepala seepissime albida; petali 
superioris alee quam in typo angustiores.

In addition to the short leaf-segments, relatively large sepals, and finally 
retuse fruits characteristic of this variety, it may be distinguished by its 
racemes, which, both in flower and in fruit, are normally laxer than in the 
other forms of this species. 
Other examples collected in Spain (Bourgeau, Pl. d'Espagne, 1850, 
No. 531 1), in Morocco (Hooker, Casa Blanca, 1871, in Hb. Kew !), and in 
the Canaries (Lowe, No. 21bis, Orotava, 1858, in Hb. Mus. Brit., ut F, parvi- 
flora fl. albis!) are closely related to, if indeed separable from this variety.
