 V. angustlfolia is a very variable plant and two extreme forms have 

 been described as species, but the characters by which they were dis- 

 tinguished pass so insensibly into each other that the chain of inter- 

 mediates appears to be unbroken. V. Bobartii, so named after the 

 Oxford Professor by Forster, is the typical V. angiistifolia of Linnaeus, 

 and is the plant which is usually found in drier soil, as on the barren 

 heaths of Mortimer, Bracknell, &e. The var. segetalis of Koch, Syn. 197 

 (the Vicia segetalis of Thuillier, Fl. Par. 367), and of Syme, E. B. iii. t. 393, 

 is the larger plant, with a longer and a stouter pod which splits the 

 calyx ; it is more frequently found in somewhat richer soil. Another 

 form, the V. uncinata, Desv., with truncate, emarginate upper leaflets, 

 should be looked for. 



V. angustifolia is found in all the bordering counties.

 5. Loddon. Sonning Cutting, Tufnail. Dry heathy ground near

 V. lathyroides is recorded for all the boi'dering counties except Wilts

In Species Plantarum, ed. 2, Linnaeus spelt the specific name with a capita 1 

 letter, but he gave no citation to show that this was required.
