13. O. CAMPESTKis, L., var. cerulea, Koch. Snepiusnana; foli- 

 olis viridibus, niaturis laxe pubesccntibus vel glabratis parvulis (lin. 

 3-4 rarius 5-6 longis) ; floribus etiam fructibus capitato-congestis 

 raro in spica laxiuscula paruin dissitis; corolla cajrulea albo-casrulea 

 nunc plane alba semipollicari ; legumiue semipollicari merabranaceo- 

 chartaceo tui'gide ovato sen oblongo semi- vel sub-bilocellato nigri- 

 canti-puberulo. — Northern Maine, Lower Canada, (near Quebec, &c.), 

 and Labrador. These are the only American stations I can cite for 

 0. campestris, taking that species to comprise 0. sordida. And as our 

 specimens have clear violet or blue corollas, when not pure white (as 

 some few are completely), I adopt Koch's name given to the quite 

 similar form in Eurojoe. The stipules are either simply one-nerved, 

 or some with a triple nerve at the apex, differing in this particular iu 

 the same plant. A slight introflexion of the dorsal suture is apparent 

 in the legumes of the South Labrador specimens collected by Dr. 

 Allen. 



14. 0. MONTICOLA. Laxe villoso-sericea, nunc subglabrata, spi- 

 thamrea ad pedalem ; foliolis oblongis vel lanceolatis (lin. 3 7 longis); 

 spica obloDga vel cyhndracea etiam fructifera couferta ; corolla aut 

 vioiaceo-purpurea aut ochroleuca vix semipollicari; legumine ovato- 

 oblongo recte acuminate membranaceo-chartaceo lin. 4-6 longo aut 

 prorsus uniloculari aut sutura ventrali introflexa semibiloculari pube 

 brevi albido-sericeo calycem campanulatum vix ultra diraidium super- 

 ante. — Northern Rocky Mountams , viz, Wyoming and Montana, 

 Parry, ■ no. 87, Canhij ; Dakota, coll. Jeiinei/, but in flower only. 

 Rocky Mountains ni British Possessions, Bourgeau, with fruit, Li/all, 

 in flower only; and Spy Hill, Macoun, 1879, no. 107, in fruit. Probably 

 some of this species is included m 0. campcstris of Hook. Fl. Bor.-Am. ; 

 but his var. spicata seems rather to belong to 0. Lamberti. It is more 

 like 0. viscida, Nutt., but is neither glandular nor viscid. Here may 

 l)elong a plant collected by Dull on a rocky talus in front of a glacier 

 at Chugachik Bay, Cook's Lilet, Alaska, in flower only.
