the pedicel. The flowers are rather large, and of a deep blue. The galea is more or 

 less arched and high, the length to twice the breadth, and beaked at the top. The medial 

 sepals are nearly orbicular, slightly oblique, from 12 to 15 mm. in diameter, with distinct 

 marginal hairs, and not unfrequently hairy inside. The lower sepals are ovate-lanceo- 

 late, 11 to 14 mm. long, and 4 to 5 mm. broad, all but rounded, or slightly acutish at the 

 top. When young the sepals are beset with scattered hairs, when older glabrous or 

 nearly completely so, but generally with more or less distinct marginal hairs. The 

 beak of the galea is generally furnished with a small tuft of hairs. The stalks of the 

 nectaries are from 1,5 to 2,5 cm. long, curved, completely glabrous, the spur itself obtuse, 

 and spirally rolled up at the top. The hind free lip is to 7 mm. long, and from 2 

 to 3 mm. broad, slightly cordately indented, with rounded sections, and completely gla- 

 brous. In A. Napellus the lip is still more narrowly and deeply indented, and frequent- 

 ly hairy. The stamens are completely glabrous, and the base furnished with broad wings 

 or fringes, reaching half way up along the filaments, generally ending in a tooth on 

 each side. This tooth, according to Reichexbach, of some systematic value, may be 

 more or less distinctly developed, and may pass through a great variety of intermediate 

 forms into nearly or altogether disappearing, the fringe then narrowing upwards, and 

 passing gradually into the filament itself. Now and then it may be unilaterally developed 

 as well. The number of the carpels is 3 (only very rarely 5), and they are completely 

 glabrous. 



Specimens belonging to this species have been collected by me in the Altaian, in 

 full flower in the second half of June. It also seemed to be rather widely distributed in 

 the alpine regions of central Asia, eastwards right up to the Sea of Okhotsk.
