PAPILIONACEAE. 



Lupinus nootkatensis Donn var." Kjellmanii Ostf. 



The species is perennial with a deep, strong primary tap-root bearing a 

 large rosette of leaves surrounding a tall flower-bearing stem, the tallest specimen 

 measuring about 24 cm. in height, the flowering raceme itself about 8 cm. In 

 fruiting specimens the large legumes are densely villous, and about 5 cm. m 

 length. 



Astragalus [Tourn.] L. 



The two species of Astragalus show a very different habit. In A. alpinus 

 the primary root persists but it is very slender; the aerial shoots are quite long 

 but very slender, prostrate, and profusely branched, bearing several leaves and 

 a terminal, long-pedunculate inflorescence. Some few secondary roots develop 

 from the nodes, and tubercles were found on some of the lateral roots. 



In A. aboriginorum, on the other hand, there is a very strong and thick, 

 primary root, often branched and crowned with numerous, compact clusters of 

 persisting internodes with scale-like leaves, supporting leafy shoots and flower- 

 bearing stems; root-shoots abound. 



As may be seen from the figure (Part A, Plate X), the arctic specimen of 

 A. aboriginorum differs in several respects from the prairie plant described and 

 figured by Hooker (Fl. bor. Am.), but Mr. Marcus Jones, to whom specimens 

 were sent for identification, kindly informed me that the arctic material repre- 

 sented the typical plant. 



With regard to the systematic position of this species Hooker (I.e.) states 

 that the perfect fruit which was unknown to Dr. Richardson has .now been seen 

 in abundance, and proves the species to be a Phaca, rather than an Astragalus. 



Phaca frigida L. 



In specimens from Bernard harbour, collected in the month of August, the 

 racemes with fruit, not fully matured, measure 15 cm. including the peduncle, 

 while in bloom the stem above ground measures only about 8 cm. in height. 

 The primary root is long and slender and the capillary, lateral roots bear tuber- 

 cles. As in the plant from Nova Zembla, which I have described and figured 

 (Dijmphna Expedition I.e.), the aerial shoots develop from the axils of scale-like 

 leaves borne upon persisting basal internodes; thus a pseudo-rhizome is also 

 possessed by this plant. 



Oxytropis Roaldi Ostf. 



Having been published in Christiania,' and perhaps not being readily 

 accessible to the reader, I herewith insert the diagnosis as written by Mr. Osten- 

 feld; it reads as follows: 



"Scapigera, usque 20 cm. alta, multiceps; stipulae alte petiolares, albae, 

 membranaceae, longe ciliatae, pars libera uninervis, e basi dilatata linearis; 

 foliola 7-8-juga, lancelato-ovata, adpresso niveo-pilosa; scapi foliis longiores 

 pilis subadpressis vel subpatulis instructi; inflorescentia subcapitata, 5-10- 

 flora; bracteae lineari-lanceolatae, calycem subaequilongae; calyx tubuloso- 

 campanulata, dentibus triangularibus tubo triple brevioribus, pube nigra 

 pilisque longioribus albis instructa; corolla calyci dimidio longior, violaceo- 

 purpurea; legumen (altum) ovato-oblongum, recte, acuminatum, membranaceo- 

 chartaceum, ca. 12 mm. longum, uniloculare vel partim semi-loculare, pube 

 breve griseo, calycem subduplo superans. Herschel Island."
