PRIMULA 



PRIMULA 



rock-garden in mild climates, with some protection. 

 Often confounded with baby primrose (P. Forbesii), but 

 the oblong long-petioled Ivs. at once distinguish it, as 

 well as the tall and open infl. 



84. pseudomalacoides, Stewart. Much like P. 

 mcdacmdes, but more delicate in every way and said not 

 to seed readily unless cross- pollinated: Ivs. more pros- 

 trate, oblong. Yunnan, China. Intro. 1908. 



85. Forbesii, Franch. BABY PRIMROSE. Figs. 3185, 

 3186. Handsome slender species, monocarpic in the 

 form first intro. but a perennial as 



now grown: loosely white-hairy, at 

 least on the Ivs. and lower part of the 

 scape: Ivs. small, 1-2 in. long, oval- 

 oblong to cordate-oblong, shallowly 

 sinuate - toothed, minutely serrulate: 

 scapes very slender, 6-14 in. high, 

 much exceeding the Ivs., often bent 

 above the whorls: fls. small (about 

 Jiin. across), light lilac, slender-pedi- 

 celled, appearing in successive umbels 

 or whorls, the segms. obcordate, calyx 

 sharp-toothed, small, somewhat loose.

 cribed so recently as 1886, and first 

 exhibited in London in 1891, this plant 

 was once a common conservatory plant 

 in America. It is a most profuse 

 bloomer, beginning to flower when not 

 more than 2 or 3 in. high and continu- 

 ing until the scapes reach a height of 

 10-12 in. It is easily grown from seeds, 

 and blooms well all winter. Unless given 

 plenty of light and room, the scapes 

 become weak and crooked. In recent 

 years it has dropped from favor with 

 florists, its place being taken in part by 

 P. malacoides. Its botanical status is 

 not well understood. 



VI. MINUTISSUVLE. 



Plant very small or min- 

 ute, producing stolons: Ivs. 

 toothed or crenate : Himalaya, 

 Thibet. 



86. minutissima, Jacq. 

 Plant very small, stolonifer- 

 ous, the stolons short and 

 leafy: Ivs. small, less than. 

 Jxjin. long, sessile, spatulate- 

 obovate or lanceolate, acumi- 

 nate, dentate or crenate, more 



or less farinose below: scape very short, almost hidden 

 among the Ivs., 1-3-fld.: bracts 1-2, small: fls. strictly 

 sessile, large in relation to the plant's size, purple; 

 calyx glabrous, tubular-campanulate, split to the mid- 

 dle with acute lobes; corolla-tube slender, the limb 

 J^in. or less across, with obcordate, deeply emarginate 

 lobes. Himalayas. 



VII. OMPHALOGRAMMA. 



Lvs. little if any lobed: fls. solitary on a bractless 

 scape, the calyx little or not at all enlarging after 

 flowering: China, Himalaya. 



A. Fls. appearing with or after the Ivs. 



87. vincifldra, Franch. Plant with a short perennial 

 rhizome: Ivs. thin, papery, oblong or oval, densely over- 

 lapping and forming a narrow erect crown, all erect or 

 nearly so, the upper ones larger, all entire but ciliate, 



3184. Primula malacoides. (X 



covered with reddish glands: scape short (6-9 in.): 

 fl. solitary, purple-violet or blue, 1% in. across, the 

 tube cylindrical or long-obconic, yellowish at the base 

 and covered with black glandular hairs outside; the 

 segms. well separated and broadly obcordate, the 3 

 upper reflexed on the tube; calyx small, not inflated.

 Gn. 77, p. 497; 79, p. 242. A most odd species, with 

 vinca-like fls., of simple cultural requirements. 



88. Elwesiana, King. Rhizome scaly: Ivs. about 4 in. 

 long, including the petiole, ovate- 

 lanceolate, very remotely and scarcely 

 denticulate, almost subentire, leathery, 

 acute, glabrous, gradually narrowed to 

 a winged, puberulent petiole: scape 

 stout, 4-6 in. high, without bracts, red- 

 hairy, 1-fld.: fls. violet; calyx pubescent, 

 parted almost to the base, with lanceo- 

 late-linear, subobtuse lobes; corolla-tube 

 pilose, broadened toward the throat, the 

 limb funnelform, with almost quadrate 

 lobes which are slightly narrowed toward 

 their base and are almost truncate and 

 denticulate at their apex: caps, cylin- 

 drical, equaling the calyx. Sikkim, Himal- 

 aya. 



AA. Fls. appearing before the Ivs. 

 89. Delavayi, Franch. Plant slightly 

 %^U soft white-hairy pubescent: Ivs. long- 

 petiolate, thin-papery, about 3 in. 

 long and almost as broad, broadly 

 ovate or suborbicular, the base 

 more or less cordate, wavy-dentate 

 or crenate: scape produced before 

 the Ivs., without bracts, 1-fld., 

 densely pubescent, laxly enveloped 

 up to the middle with fuscous, 

 membranaceous, very broad scales: 

 fls. bright purple; calyx broadly 

 campanulate, deeply parted, with 

 linear-lanceolate lobes about Yim.. 

 long which are entire or denticulate 

 and acute or obtuse; corolla out- 

 side pilose, the funnel form tube 

 broad, slightly constricted above 

 the base, then gradually broadened, 

 the throat sprinkled with hairs, 

 with oblong - ovate incised 

 lobes: caps, ovate-oblong, 

 %-l in. long, %in. thick.

VIII. BULLAT.E. 



Lvs. strongly rugose or 

 bullate, hairy or glandular, 

 more or less coriaceous, little 



if any lobed, small (2-4 in. long) : fls. pedicelled: China, 



Thibet. 



90. pvalifSlia, Franch. Lvs. membranaceous, finally 

 subcoriaceous, ovate, obtuse, crenulate or subentire, 

 ciliate, contracted abruptly to the petiole which equals 

 or is shorter than the blade and is more or less covered 

 with red hairs: scape 1-6 in. high, equaling or shorter 

 than the Ivs., somewhat red-hairy: bracts lanceolate, 

 acuminate: fls. purple; calyx open-campanulate, with 

 lanceolate acuminate, hairy lobes; corolla-tube broad- 

 ened to the concave limb, which is up to 1 in. across, 

 with obovate slightly emarginate lobes. Cent. China. 

 Intro. 1906. G.C. III. 38:70.
