than the Central European form ; it comes near to the Faroese 

 and Icelandic one." 



In the original description of A. amitidens Buser in Bull. 

 Herb. Boiss. ii. p. 104, 1894, a long and detailed account is given 

 from which I translate the following points of distinction from 

 allied forms : — 



" Plant medium sized, rather slender and graceful, not tall, 

 loith stems dcciimhent, rather yellowish green. Leaves strongly 

 undulate, lobes of lower leaves very rounded with a cut between 

 them equal to 2-3 of the teeth (recalling the lower leaves of incisa), 

 those of the upper leaves parabolic-triangular, acute, toothed all 

 round. Teeth numerous, 6-9 on each side, very equal, small or 

 medium size, narrow and close, tapering acute, penicillatc, conni- 

 vent, very silky and ciliate. Leaves subco7icolorous, clear shining 

 green above, ^jaZe beloio, becoming yelloio ivith age and by desicca- 

 tion, glabrous, or the upper ones radiated with silky lines in the 

 folds above, and silky along the veins and hairy upon the lobe 

 next the petiole below. Petioles slender, hairy, often faintly so, 

 with long stiff laxly applied hairs or a portion of the petioles 

 glabrous. Stems rather numerous (2-5), spread-out in the grass, 

 slender, hairy at the base (internodes 1-2) with long stiff, ap- 

 pressed or laxly-set hairs, glabrous for the remainder. Stem leaves 

 (lower) cut as far as a third with lobes semi-obovate and with 

 conuivent toothing ; the upper cut as far as a half, with lobes 

 separated and with porrect toothing. Lower pedicels long and 

 divergent, upper quickly diminishing and closer. Flowers rather 

 large, dark yellowish green, glabrous. Urceoles when young 

 broad-obconic, a little shorter than the sepals, when mature tur- 

 binate or turbinate-ovoid, equalling the sepals. Calyx and calicule 

 relatively well developed, recalling glabra. Sepals triangular- 

 ovate, acute, obliquely erect after flowering and usually conceal- 

 ing the moderately exserted styles ; calicule segments half as 

 broad and nearly as long (f-1) as the sepals, lanceolate, very 

 acute. Pedicels equalling or twice as long as the urceoles. 



" Leaves 2,5-10,5 x 1,8-9 cm. Stems 10-39 cm. Petioles 

 2-20 cm. Flowers 3-3,5 mm. long, 3,5-4 broad. Urceoles 

 1-1,5 mm. Sepals 1,3-1,5 mm. Pedicels 2,5-1." 



A description is then given of "two allied races " of A. acutidens, 

 nQ,med A. cuspideiis Sbud A. flavescens respectively. These will be 

 alluded to later. 



I may confess at this point that I have been unable to separate 

 satisfactorily all Buser's species and varieties, even with the 

 help of the careful descriptions he has given and with authentic 

 dried specimens. Others seem to have had the same difficulty — 

 Briquet in Burnat, Fl. Alpes-Marit. iii. 149 (1899) calls the plant 

 under discussion A. vulgaris L. var. y acutidens, and remarks 

 that A. cuspidens Buser and A. flavescens Bus. are, in his opinion, 

 mere variations of this variety. Rouy and Camus (Fl. France, 

 vi. 451, 1900) go further ; they combine A. acutidens and A. cus- 

 pidens under A. connivens Buser (in Bull. Herb. Boiss. 1894, 107) 

 as a subspecies of A. vulgaris L. Finally, H. Lindberg (Nord.
