8. O. Pakkyi, Sericeo-canescens; foliis scapisque 1-2-floris de- 

 mum spithamasis; foiiolis 7-9-jugis oblongo-lanceolatis lia. 2-3 longis ; 

 calyce brevi griseo-pubescente, dentibus tubo campanulato aiquiloiigo : 

 legumine (liu. 5-6 longo) hinc profunde sulcato pube brevi griseo. — 

 Rocky Mountains of Northern New Mexico and Colorado, near the 

 limit of trees, Parry^ Hall S^ Harbour, Greene, with mature fruit in 

 July : flowers not seen. Was named by me 0. arctica in Hall &, 

 Harbour's collection, no. 143, and 0. Uralensis, var. pumila, in Proc. 

 Am. Acad. vi. 235, and 0. Lagopxis, Nutt., was wrongly referred to it. 

 From the references this would seem to be the plant described as 

 0. arclica by Bunge, Oxytr. 97, but his character does not accord with 

 Hall & Harbour's specimens, which want the flowers, and are very 

 different from Brown's plant (which I now know). It would seem that 

 Bunge's description was drawn partly from Hall & Harbour's speci- 

 mens, partly from Brown's character of 0. arctica, and partly from 

 that of 0. Lagopus, Nutt., which I had very wrongly adduced to 

 Brown's species. 



= = Foliola 4-6-juga, villoso-sericea : legumen ovato-oblongum, haud 

 stipitatum, semibilocellatum, cum calyce sa^pius uigricanti-pubescens: 

 scapi folia superantes, capitato-2-5-flori. 



9. O. AUCTiCA, R. Br. App. Parry Voy. 278 (non 309) ; Hook. Fl. 

 Bor.-Am. 1. c, excl. /3 & S. 0. Uralensis, var. arctica, Ledeb. Fl. 

 Ross. i. 594. Probably also 0. Uralensis, var. pumila, Ledeb. 1. c. — 

 Arctic sea-coast, coll. first in Admiral Parry's voyage, also by Richard- 

 son and by later arctic explorers. Certainly not a form of 0. Uralen- 

 sis ; the stipules destitute of the nervation of that sj^ecies, having 

 only a midnerve and one or two recurving veins. Plant quite unlike 

 the forms of 0. nigrescens and 0. podocarpa, which have been referred 

 to it. 



==== = Foliola aut 3-5, aut solitaria; legumen obi on go-ova turn, 

 brevi-stipitatum, nigricanti-pubescens, sutura ventrali intruj^a vix 

 semi-bilocellatum : scapi folia superantes, 1-4-flori. 



10. O. Mertensiana, Turcz., Ledeb., Bunge, Oxytr. 116. — I have 

 fruiting specimens of this from Arakamtschetchene Island, on the Asi- 

 atic side, within Behring Strait, collected by C. Wright. From my notes 

 made in the Kew herbarium, I am disposed to consign to it, rather than 

 to 0. arctica, the specimens referred to the latter species by Seemann
