glaucous; the radical leaves blternate, leaflets rotuudato-crenate, three-lobed, the segments generally bifid 

 and obtuse; those of the stem gradually becoming more simple upward, at length only trifid. Flowers 

 extenially of a bright red colour, more or less yellow at the extremities of the petals. The spur is liable to 

 some variation in its relative length and thickness. As the A. hybrtda of Sims (Bot. Mag. t. 1221,) is 

 justly considered to be the offspring of A. vulgaris and A. canadensis, so is the present of A. hrevistijla and 

 canadensis; partaking, however, more of the nature of the latter in the general shape and large size of the 

 flower and comparative length of the spur, and showing Its affinity with the former in its pubescent leaves 

 and stem, and in the colour of its inflorescence.

Hab. Rocky Mountains, between lat. 52° and 56°. Drummond. — I think the above synonyms may with 

 safety be referred to this species. The plant varies sometimes with white flowers, according to Mr. Drummond. 



2. Z). simplex ; petiolis basi dilatatis, foliis 3-partitis profunde laciniatis laciniis lineari-

Caulis erectus, 3-pedalis et ultra, vix ramosus, pubescens. Folia valde pubescentia, tripartito-multifida, 

 laciniis linearibus acutis, foliorum superiorum august iori bus. Petiolus 2-3 uncias longus, basi dilatatus,

Hab. On the subalpine range, west of the Hocky Mountains, near the Columbia; plentiful. Douglas. — 

 Allied to D. anireum, Mich,, but that has the leaves glabrous, the spikes shorter, and the flowers with a 

 much smaller spur, which is curved upwards. 



3. D.Menziesii; petiolis basi vix dilatatis, foliis 5-partitis, lobis trifidis linearibus in- 

 tc^ris, bracteis S-fidis, radice grumosa. — De Cand, Si/st, Veget, v. 1. p, 355, Prodr, v, 1.

Hab. North-West coast of America, Menzies. Kotzebue*s Sound. Capt. Beechey's Collection. Common 

 under the shade of solitary pine trees, at Puget Sound, the Columbia rdver, and in California. Douylas.— 

 M. De Candolle well observes how nearly this species approaches to D. pentagymm, a native of the 

 South of Spain and North of Africa; scarcely differing hut in its tuberous roots. To me also it appears to 

 resemble too much the Z>. tricorne.
