 coarsely toothed, grav-white when full-grown. Intro.

142. Olgae, Regel. Glabrous, not farinose: Ivs. about 

 1 2-1 in. long, obovate-oblong, obtuse, narrowed into 

 broadly winged petiole, crenulate-denticulate : scape 

 about 3 in. tall, exceeding the Ivs., bearing a dense 

 umbel of rose-lilac fls.: bracts lanceolate, acute, some- 

 what saccate at base : calyx green and purple-striped, the 

 lobes lanceolate and acute; corolla-tube twice as long 

 as calyx, the lobes obeordate and bifid. Turkestan. 

 Alpine garden : late spring and early summer. 



143. farindsa, Linn. (P. Warei, Stein). Fig. 3191. 

 Farinose at least when young: 4-8 in.: Ivs. variable in 

 size, glabrous, veiny, elliptic-lanceolate, obovate or 

 ovate-rotundate, obtuse, frequently gradually narrowed 

 to a petiole which is scarcely distinguishable from the 

 blade, denticulate or subentire: scape exceeding the Ivs. 

 *2-12 in. high, sometimes slender, sometimes stout, 

 bearing a rather dense or lax many-fld. umbel: bracts 

 lanceolate, acute, their base slightly saccate: fls. lilac, 

 blue, or becoming purple, the throat yellow; calyx urn- 

 shaped, green, with oval or subtriangular obtuse or 

 rarely subacute lobes; corolla-limb >in. or less across, 

 with obeordate deeply emarginate lobes: caps, sub- 

 equaling or almost twice exceeding the calyx. Gen- 

 erally distributed in boreal and alpine regions of the 

 northern hemisphere, in X. Amer.. occurring in Maine, 

 on Lake Superior, and in the mountains as far south as 

 Colo. Gn. 29, p. 385; 62, p. 29; 63, p. 406 (var. alba);

reduced in Fig. 3191). G. 8:456. F.E. 15:674. A 

 widely variable species, with which Pax & Knuth unite 

 P. mistassinica and others. The Rocky Mt. form has 

 been separated by Rydberg as P. americana. It is 

 difficult to find good dividing lines between the many 

 geographical forms of this type, and one must combine 



them all into P. farinosa or keep many of them separate 

 as species. The above description of P. farinosa is the 

 inclusive one. More narrowly defined, it may be charac- 

 terized as follows: Ivs. obovate-lanceolate, farinose 

 beneath: fls. variable in color and breadth of lobes, but 

 usually pale lilac with yellow center, umbellate; calyx 

 oblong-ovate, with linear teeth; corolla-limb flat; 

 corolla-lobes obeordate and rounded below, distant, as 

 long as the tube: caps, twice as long as calyx. 



144. scotica, Hook. The form in the extreme north 

 of Scotland, on sandy heaths: half as large as P. 

 farinosa: Ivs. obovate-lanceolate: fls. bluish purple 

 with yellow center; calyx swollen, the teeth short- 

 ovate and blunt; corolla-limb flat, the lobes broadly 

 obeordate and about half the length of the tube: caps, 

 scarcely exceeding the calyx. 



145. modesta, Biss. & Moore (P. farindsa subsp. 

 modesla, Pax). Treated as a subspecies of P. farinosa 

 by Pax & Knuth: Ivs. farinose, about 2% in. long and 

 one-sixth as broad, spatulate, dentate-serrate: scape 

 about 5 in. tall, 10-fld.: bracts setaceous: pedicels 

 about 1 in. long: calyx campanulate. Japan. R.H.S. 

 39:180. 



146. davftrica, Spreng. (P. farindsa subsp. davurica, 

 Pax). Small or tall, 2-12 in. or more: Ivs. 1-3 in. or 

 more long, less than J^in. wide, lanceolate or narrow- 

 elliptic or narrow oblong-lanceolate, obtuse, nearly or 

 quite devoid of farina, wing-petioled, very nearly or 

 quite entire: fls. rose or lilac-rose, on filiform pedicels. 

 Siberia, Mongolia, subarctic N. Amer. 



147. mistassinica, Michx. (P. farindsa subsp. mis- 

 tassinica, Pax. P. pustila, Hook.). Plant small and 

 slender, with only mere traces of mealiness if any: Ivs. 

 only J^in. long, stalked or not, spatulate or obovate, 

 toothed or repand: scape about 6 in. tall, with few fls., 

 the latter flesh-colored (rarely white) and shorter than 



3190. Primula rosea.

 England, Cent. N. Y., Lake Superior, etc. B.M. 2973 (?), 

 3020. 



148. magellanica, Lehm. (P. farindsa var. magel- 

 Idnica, Hook. f.). The south hemisphere representative, 

 growing in S. Chile, Terra del Fuego, Patagonia : robust, 

 4-8 in. tall: Ivs. farinose beneath, rhomb-elliptic, 

 crenulate-denticulate: scape strong, exceeding the Ivs.: 

 fls. nearly capitate, flesh-colored or white; calyx-teeth 

 subacute: seeds large and granulate.
