44 THE GEKUS PUMARIA IN BRITAIN 



of F. agraria, though the notched beak is, on the average, shorter; 

 and both plants distinctly differ in this organ from F. major Bad., 

 in which it is altogether more obovate and less keeled and beaked. 

 Moreover, the rugosity of the fruit of F. occidentalis is less dense 

 and uniform than in either of its allies ; and a further peculiar 

 feature that escaped my notice when first describing the plant is 

 the development of a conspicuous tubercle at the base of each of 

 its nearly obsolete apical pits, from which descends a more or less 

 obvious longitudinal ridge. 



It may be added that, besides the points of difference already 

 mentioned for F. occidentalis, F. atlantica may be separated by its 

 still larger fruits, and F. ncpestris Boiss. (including F. arundana) 

 by its lanceolate sepals, narrowly winged pink petals and smaller 

 fruits. 



As was to be expected, F. occidentalis has been found in a few 

 additional Cornish localities since its publication as a species, but 

 no earlier specimens under other names have come under my 

 observation, except one, collected at Lelant by Mrs. E. S. Gregory 

 in 1895. I think the Cornish botanists have not made any very 

 serious attempts to discover it in the herbaria of their predecessors

A plant of usually very robust habit and more or less branched, 

 in fields suberect or decumbent, on walls and hedge-banks with 

 long, trailing stems, sometimes climbing to a considerable height 

 by its cirrhose petioles. Leaves irregularly 2-3 pinnatisect, light 

 green, with leaflets cut into oblong-lanceolate, acute or mucronate 

 lobes. Bacemes 12-20-flowered, rather lax and lengthening in 

 fruit, about equalling the peduncles but the lower sometimes 

 shorter. Bracts lanceolate, acuminate, usually nearly as long as 

 the fruiting pedicels but occasionally much shorter. Friciting 

 pedicels much thickened at the tip, straight and suberect in 

 field forms or arcuate and slightly decurved in rampant plants. 

 Sepals 4-5|- mm. long and 2-3 mm. broad, ovate, peltate, 

 acute or shortly acuminate, frequently incise-dentate toicards the 

 base, white with greenish dorsal nerve, at least as broad as the 

 corolla-tube. Corolla large and handsome, 12-14 mm. long, rosy- 

 ivhite in colour, with the tip of the inner petals blackish red and 

 the loings of the iipper one similarly coloured externally, with well- 

 marked, broad lohite margins before fertilization. Upper petal 

 broad and dorsally compressed, subacute, with broad, short w^ngs 

 reflexed upwards, exceeding the green keel and reaching the apex ; 

 spur relatively short. Loiver pietal often deflexed and free, with 

 green keel, and broad, whitish, spreading or slightly deflexed 

 margins, which extend from the base to the apex and are some- 

 times a little dilated above so as to form an almost subspathulate 

 outline. Fruits large, fully 3 mm. long and about as broad ; sub-
