 upright slightly toothed Ivs. (often untoothed), dark

 tificated by Roy. Hort. Soc., 1913. "Like most mem- 

 bers of the Nivalis group of primulas, P. Purdomii 

 died after flowering. It is a plant of vigorous growth 

 and robust habit which prefers a loamy soil" (B.M.).

 the middle, with lanceolate acute not at all rarely 

 unequal lobes; corolla-limb %in. across, with shortly 

 tabulate, sometimes entire lobes: caps, ovate, obtuse,

 pulchella, with fewer and smaller fls., less depth of 

 color and also narrower smaller Ivs. China. Intro.

197. Cusickiana, Gray. Scapes 6 in. or less tall, each

 narrow-oblong, about 2 in. long, entire or very nearly so: 

 involucre-bracts 2 or 3, conspicuous, unequal: corolla- 

 lobes retuse, the tube little 'if any exceeding the green 

 calyx-lobes which are white striate between. Early 

 spring. E. Ore. Offered by dealers in native plants. 



198. secundifldra, Franch. Glabrous: Ivs. 2-4 in. 

 long, papery, golden farinose below when young, fi- 

 nally becoming bare, oblong or ovate-oblong, finely and 

 evenly serrulate, acute, narrowed to a winged petiole 

 which is scarcely distinguishable from and equaling or 

 shorter than the blade: scape exceeding the Ivs., 8 in. 

 or more high, stout, bearing a 1-sided, 6-10-fld. umbel: 

 bracts triangular, acuminate: pedicels soon nodding, 

 secund: fls. bright violet; calyx dark purple, marked 

 with 5 white lines, ovate-campanulate, split to the 

 middle, with deltoid, lanceolate, acute lobes; corolla- 

 tube cylindrical, the limb funnelform, %in. across, with
