PRIMULA 



PRIMULA 



nately somewhat 7-nerved, both surfaces densely 

 finely rusty-punctate: scapes frequently several, 2-3- 

 fld.; the pedicels very slender-puberulent : fls. rose- 

 lilac; calyx urn-shaped, 5-cleft to the middle, the lobes 

 oblong, obtuse, strewn especially at the margin with 

 resinous red dots; corolla salver-shaped, the lobes 

 ovate, 2-cleft: caps, spherical, not exceeding the calyx- 

 tube. Cent. China. 



DD. Lvs. membranaceous or thin, oblong in general out- 

 line, doubly crenate and often somewhat lobed. 



70. cortusoides, Linn. Lvs. in a rosette on the 

 ground, rather large and soft, loose-hairy (at least on 

 the midrib and petioles), ovate-oblong or cordate- 

 oblong, irregularly many-notched: scapes few to sev- 

 eral, 6-12 in. tall, much exceeding the Ivs., very straight, 

 hairy: bracts linear: fls. rose-colored, about 1 in. across, 

 short-pedicelled, in a loose many-fld. umbel, the segms. 

 obovate and deeply notched or even lobed. W. Siberia.

 A handsome hardy species, blooming in May in the 

 northern states, and represented by garden forms; 

 known sometimes as "bear's-ear primrose," from the 

 large radical Ivs. G. 2:207 (var. amoena); J.H. III. 

 44:277 (var. grandiflora lilacina). It is a question, 

 however, whether P. cortusoides is now much known 

 in cult., the plants grown under this name being per- 

 haps P. Sieboldii and P. saxatilis. It is recognized, 

 according to Balfour, by the short pedicels of the fls. 



71. saxatilis, Komar. Fig. 3183. Plant pubescent: 

 Ivs. oblong or broadly oblong-ovate from a cordate or 

 subcordate base, incise- frequently slightly curled- 

 incise-lobed, the lobes sometimes subentire, sometimes 

 crisped or dentate; the petioles frequently exceeding the 

 blades: scape exceeding the Ivs., pubescent below, sub- 

 glabrous above, bearing 1-10 fls. : bracts linear: fls. rose- 

 violet; calyx ovate-cylindrical or narrowly campanulate, 



3181. Primula Sieboldii. 



prominently nerved, with deltoid acute very shortly 

 puberulent lobes; corolla tubular, the limb up to %in. 

 across, with emarginate lobes: caps, oblong, included, 

 very glabrous. E. Siberia. R.H.S. 39:173. Said to 

 be cult, under the name of P. oreodoxa. Pedicels much 

 exceeding the bracts. 



DDD. Lvs. membranaceous, rounded or deltoid in general 



outline, lobed. 

 E. Foliage bullate or blistered. 



72. violoddra, Dunn. Plant pubescent: Ivs. reni- 

 form or orbicular, frequently bullate, base cordate, 

 lobed, the lobes bicrenate; the petiole longer than the 

 blade, covered with violet hairs: 



scape 8-12 in. high, bearing 2-3 

 superposed umbels, rarely only 

 1 : bracts small : fls. with the odor 

 of violets, rose-lilac; calyx sub- 

 glabrous, green, narrowed at the 

 base, with very acute strongly 

 nerved lobes; corolla-tube cylin- 

 drical, the mouth yellow, the limb 

 up to %in. across, with obcor- 

 date lobes. Cent. China. 



EE. Foliage not bullate or blistered. 

 F. Lobes of Ivs. obtuse (the lobes 



sometimes with more or less 



acute large teeth). 



73. mdllis, Nutt. 

 Plant softly hirsute- 

 pubescent, 1 ft.: Ivs. -^%if|pl;s 

 deeply cordate at the {''fflgjjjjijtil 

 base, the sinus closed, 



cordate in general 

 outline, sinuate- 

 lobed, crenulate-den- 

 ticulate, softly pu- 

 bescent ; the petiole 

 densely pubescent, 

 equaling or exceeding 

 the blade: scape 

 pubescent, 8-10 in., 

 after flowering grow- 

 ing to as much as 16 

 in . high, much exceed- 

 ing the Ivs., bearing 

 3-5 many-fld. super- 

 posed umbels: bracts lanceolate, the upper narrower: 

 fls. bright rose; calyx intense red, soft-hirsute, tube 

 turbinate, with spreading acute lobes; corolla-limb more 

 or less oblique, ^-%in. across, with obovate emargin- 

 ate lobes. E.Himalayas. B.M. 4798. F.S. 12:1230. 

 Gn. 76, p. 424. G.W. 13, p. 123. R.H.S. 39:184. May 

 and June to July, requiring a moist or boggy place. 



74. sinomollis, Balf. f. Lvs. gray-hairy, rounded, 

 petiolate, very shallowly rounded-lobed or scalloped: 

 scapes long, bearing superposed whorls of red fls. : calyx 

 cup-shaped to campanulate, ribbed, with straight erect 

 lobes. Yunnan, China. Intro. 1913. R.H.S. 39:148. 



75. septemloba, Franch. Whole plant scattered with 

 soft white hairs: Ivs. up to 3% in- diam., in outline 

 orbicular, deeply cordate, sparsely pilose, 7-lobed, the 

 lobes one-third the depth of the If .-diam., broadly ovate 

 or triangular, obtuse but sometimes with more or less 

 acute large teeth, denticulate; the petioles somewhat 

 hairy, much exceeding the blade: scape up to 12 in. 

 high, slender, clothed with spreading hairs, bearing a 

 small cluster of fls.: bracts linear-lanceolate, obtuse: 

 fls. reddish purple, semi-pendulous and somewhat fra- 

 grant; calyx glabrous, tubular-campanulate with lanceo- 

 late acute lobes; corolla-limb about ^in. across, con- 

 cave, with obovate emarginate lobes. Cent. China.

76. oculata, Duthie. Allied to P. septemloba, with 

 geranium-like Ivs. and red-purple drooping fls. which 

 are darker in color than those of the related Chinese 

 species. W. China. Intro. 1904. 



FF. Lobes of Ivs. acute. 



77. Kaufmanniana, Regel. Lvs. pubescent, becoming 

 glabrescent, petiolate, about 2 in. long and broad,
