THE GENUS FUMARIA IN BRITAIN 31 



late, with a spathuLite dilation of the wings which, when reflexed, 

 cover the abruptly terminated keel. Loiver petal with narrow and 

 spreading margins, w^hich are somewhat dilated towards the apex, 

 forming a suhspathitlate outline. Inner petals cm-ved upwards. 

 Fruit of moderate size, 2| mm. long and equally broad, squarish 

 in pirofile, truncate or even subemarginate, with a short but per- 

 sistent apiculus, laterally compressed but obscurely keeled, and 

 shortly narrowed below to an obscure fleshy neck about as broad 

 as the tip of the pedicel ; wdien dry, faintly rugulose, with shallow^ 

 but rather broad apical pits. 



4. FuMARiA PARADOXA, nov. spec. 



The handsome fumitory for which the above name is proposed 

 was first brought to my notice in October, 1904, by Mr. F. H. 

 Davey, who sent for identification fresh specimens gathered in 

 cultivated fields at Gilly Tresamble, in the neighbourhood of 

 Penryn, in West Cornwall. On examining this material, I found 

 that, while differing from the British Fumitories, it somewhat 

 resembled certain specimens at the British Museum and agreed in 

 most respects with Jordan's account of his F. vagans. I was 

 unable, how^ever, to identify it with this or any described 

 species, and as the plant, which Mr. Davey at first thought grew 

 also at Perranzabuloe, could afterwards be found only at Gilly 

 Tresamble, its occurrence in such a restricted habitat led me to 

 suspect it to be a recent introduction which would presently be 

 recognized as occurring on the Continent. Further specimens 

 were sent me by Mr. Davey in the autumn of the following year, 

 and in September, 1907, I availed myself of an opportunity to 

 visit Gilly Tresamble in his company, in order to see the plant in 

 situ. At that date it was growing sparingly in two fields, accom- 

 panied by F. Borcei, F. Bastardi, and the other new form already 

 mentioned in this paper, F. neglecta. 



In the summer of 1909 I received a fumitory through the 

 Berlin Exchange Club, which, though showing no fruits, seemed 

 identical with this Cornish plant. It was sent out as F. affinis Hoff. 

 {sic), and had been collected in April, 1906, by Senor B. Vicioso 

 at Calatayud, in the Spanish province of Aragon. Sefior Vicioso 

 has since been kind enough to furnish me with further material of 

 this plant, collected early in 1910, which leaves no doubt as to its 

 identity with the Cornish form, and on re-examining the two with 

 the specimens in Herb. Mus. Brit., I recognize that they both 

 belong to the same species as a very fine example there, showing 

 abundant flowers and fruit, labelled " E. Bourgeau, PI. d'Espagne, 

 1863. Fumaria Bastardi Bor. (Coss.), Champs incultes pr^s 

 Navalmoral, 10 Mai." 



The salient features of the three plants are the long, lax 

 racemes of showy flowers, borne on arcuate-decurved pedicels 

 recalling those of F. capreolata ; the subentire, oval sepals ; and 

 the nearly smooth fruits of at least moderate size and somewhat 

 muralis-like form. The finest flowers are those of the Navalmoral 

 specimen, in which the corollas attain a length of 13 mm., but
