 specimens which exhibit a gradation between it and the follo^ving species. Var. B, has the leaves very 

 free from hairs, and somewhat fleshy.

and Collie, 3. Highest summits of the Rocky Mountains. Drummond. — The specimens given in the " Unio 



ItimraricC collection, from Cambre d*Aze and the Vallee d'Eynes in the Pyrenees, under the name of O, 



Uralensis, (i. microphylla, exactly correspond with the more usual state of our plant. Mr. Drummond's var. 



from the most elevated ridges of the Rocky Mountains has the leaves, especially the old ones, nearly 



glabrous, the leaflets narrow; the legume greatly swollen, or inflated, thin and membranaceous, scarcely 

 at all hairy. 



4. O. foliolosa ; acaulis, incano-villosa, foliis numerosis, foliolis approximatis ovatis 

 seu oblongo-ovatis subacutis, scapis folio longioribus pilosis, capitulis late ovatis (parvis), 

 floribus congestis patentibus inferioribus reflexis, bracteis lineari-lanceolatis calyce 

 nigro-hirsuto brevioribus, leguminibus remotiusculis Jeflexis (vix maturis) cylindraceis 

 acutis nigro-hirsutis. 



Radix perennis, subfusiformis, sublonge descendens, apice fibroso-ramosa, superne multiceps. Folia 

 nmnerosa, radicalia digitem longa, erecta vel erecto-patentia ; foliola 23-25, subarcte-approximata, ovata, seu 

 oblongo-ovata, 3-4-lineas longa, acuta, una cum rachide subappressim pilosa. Petiolus ad basin patenti- 

 pilosus. Stipiilis lanceolatse, acuminatae, sublonge pilosje. Scapi plurimi ex eadera radice foliis longiores, 

 deraum fructlferi, duplo longiores, pubescenti-pilosi, pilis ad basin longioribus magisque patentibus. Capitula 

 late ovata seu subglobpsa, ratione plantae parva, floribus compactis, patentibus, inferioribus reflexis, Bractecp. 

 herbaceae, lineari-lanceolatse, pilosse, calycibus nigro-pilosis breviores. Denies calycini subulati, tubi longi- 

 tudine. Petala intense caeruleo-purpurascentia, basi fere alba. Carina obtusa cum mucrone conspicuo 

 subrecurvo. Zegumina, vix matura, omnia pendentia, unciam longa, fere exacte cylindracea, acuta, dense 

 nigro-pubescenti-hirsuta, basi in stipitem calycis tubo breviorem attenuata. 



H\B. From Carlton-House to the Rocky Mountains, in lat. 54°. — This very elegant species of Oxytropis 

 has an afl&nity on the one hand ^vith O, montana, and on the other with O. ccerulea ; agreeing with both in 

 the general shape of the leaflets, and their regular and close insertion upon the rachis, and in the deep-blue 

 colour of the flowers, pale at the base of the petals. From the former it differs in its more compact and tufted 

 growth, smaller heads, and smaller and more patent flowers, and in the drooping, cylindrical, very black, and 

 hairy legumes ; from the latter, in its less silvery foliage, more obtuse leaflets, and far shorter and more 

 compact heads of flowers. 



5. O. argentata; acaulis, foliolis obovato-lanceolatis sericeo-argenteis, scapis folia
