 Behring Straits (both sides and islands) to the Rocky Mountains and high Sierras. 



Var. latilobum. Leaves thin, ovate or oval, repand or undulate-toothed, long- 

 petioled : scape a span to a foot high, 1-several-flowered : calyx-lobes ovate or triangular- 

 ovate, not longer than the tube, about half the length of the oblong capsule. Var. frigi- 

 dum, Watson, 1 c., in part. D. dentatum, Hook. Fl. ii. 119? Cascade Mountains, British 

 Columbia or Washington Terr, to Wahsatch Mountains, Utah. 



3. PRlMULA, L. PRIMROSE. (Late Latin, from primula veris, the first 

 in spring, i. e. to blossom.) Flowers in some species, but not in others, dimor- 

 phous, i. e. in different individuals either with elongated style and low-inserted 

 stamens, or with short included style and stamens inserted high in the throat, 

 so that the tips of the anthers show in the orifice of the corolla. Few N. Amer- 

 ican species of this large Old World genus, and none of the True Primrose or 

 Cowslip set, with thin rugose-veiny leaves. All perennials, chiefly with fibrous 

 roots from a short crown : ours glabrous or nearly so. 



* Flowers small ; the tube of the salverform corolla not over 2 or 3 lines long and little surpassing 

 the calyx; lol>es obcordate ; throat with more or less of a callous ring or processes. Species 

 passing into each other, probably reducible to two. 



P. farinosa, L. More or less white mealy on the leaves, calyx, &c., at least when young : 

 leaves from cuneate-lanceolate to obovate-oblong or spatulate, denticulate, an inch or less 

 long, tapering into a short margined petiole : scape 3 to 9 inches high : umbel few-several- 

 flowered, close : pedicels seldom equalling the flower, sometimes very short : corolla from 

 flesh-color to lilac, with yellowish eye; the lobes cuneate-obcordate, rather distant at base, 

 2 or 3 lines long. Varies with mealiness sparing or deciduous. Fl. Dan. 1. 125; Curt. 

 Lond. ii.21 ; Engl. Bot. t. 6. P. Scotica, Hook, in Curt. Lond. iv. 1. 133; Engl. Bot. t.2608, 

 form with almost capitate umbel. Labrador, Nova Scotia and Maine, Lake Superior, 

 Rocky Mountains from Colorado northward, through Arctic America. (Antarctic Amer., 

 Eu., N. Asia.) 



P. Mistassinica, Michx. Green, without mealiness or with mere traces of it, small 

 and slender: leaves half inch long, with or without a short petiole, spatulate or obovate, 

 repand or toothed : scape 2 to 5 inches high, 1-8-flowered : lobes of the flesh-colored corolla 

 from broadly to narrowly obcordate, H or 2 lines long. Fl. i. 124; Pursh, Fl. i. 137;

 banks and shores, N. New England and New York to Lake Superior and N. Rocky Moun- 

 tains to the Arctic Sea. (Greenland, N. Eu.) 



P. borealis, Duby. Between the preceding and the next : very slender : leaves nearly 

 of the latter, but only 3 to 5 lines long : scape 1-5-flowered : lobes of the purple corolla 

 oblong, barely 2 lines long, deeply notched. DC. Prodr. viii. 43 ; Herder in Radde, iv. 

 114. Alaska and Islands to Kotzebue's Sound, &c. (Greenland, being apparently P. 

 Eiialikce.nsis, Hornem. Fl. Dan. 1. 1511.) 



P. Sibirica, Jacq. Green, not at all mealy : leaves round-ovate, oval, or obovate, entire 

 or -nearly so, a quarter to a full inch long, slender-petioled : scape a span high, few- 

 flowered : bracts of the involucre almost spur-like at base : lobes of the lilac-colored 

 corolla broadly and usually deeply obcordate, 3 to 5 lines long ; the throat broadened.
