PRIMULA 



PRIMULA 



Var. inflate, Reichb. (P. inflate., Duby. P. canescens, 

 Opiz. P. officinalis var. canescens, Beck. P. pannonica, 

 Kerner). Calyx equaling or surpassing corolla-tube, 

 more or less open-campanulate, about %in. long; 

 corolla }^-/iin. across: Ivs. contracted or narrowed 

 into petiole, cano-tomentose or glabrescent beneath. 

 Var. suaveolens, Reichb. (P. 

 Columns, Ten. P. offidnalis var. 

 Columns, Pax). Calyx campanu- 

 late; corolla-limb little concave or 

 almost plane, about %in. across: 

 Ivs. ovate to oblong-ovate, cor- 

 date, densely white - tomentose 

 beneath. 



3186. Primula Forbesii. 

 (XX) 



AA. Limb of corolla plane. 



B. Scape evident. 



c. Fls. yellow. 



98. elatior, Hill. OXLIP. Lvs. 



rugose, membranaceous, ovate or 



oblong, the apex, obtuse, more or 



less contracted or narrowed to the 



petiole, crenulate or denticulate, 



more or less pilose or canescent- 



tomentose below; the petiole more 



or less winged, shorter than or 



equaling the blade: scape more or 



less pubescent, 4-8 in. high, bear- 

 ing a many-fld. umbel: bracts 



linear, acute, small : fls. pale yellow, 



turning green in drying, scentless; 



calyx more or less pubescent, 5- 



ribbed, tubular, with narrowly 



lanceolate acute lobes that are 



shorter than the tube; corolla-tube 



cylindrical, the limb flat, more or 



less than %in. across, with obcor- 



date, emarginate lobes: caps. 



cylindrical or oblong, equaling or 



exceeding the calyx. Eu., especi- 

 ally in the mountains and the 



northern part, .southeast to Cau- 

 casus and Persia. Gn. 62, p. 217. 

 G.W. 15, p. 269. Var. gigantea, Hort., is offered, with 

 fls. more than 1 in. across, yellow predominating. For 

 cowslip x oxlip, see New Phytologist, vi:162 (1907). 



From the cowslip the oxlip differs in having the fls. 

 more or less upright, the corolla-limb is plane and the 

 throat is open without folds. The species is widely 

 variable. Var. carpathica, Griseb. Lvs. ovate or 

 oblong, the petiole more or less winged and the blade 

 strongly rugose and crenulate : calyx usually ventricose- 

 tubular before flowering: caps, cylindrical. Carpa- 

 thians. Var. intricate, Pax. Lvs. ovate-elliptic, grad- 

 ually attenuate into a winged petiole, little rugose, 

 green beneath: scape only equaling the Ivs.: calyx 

 tubular, the lobes triangular and acute: caps, short- 

 cylindrical, equaling or perhaps exceeding the calyx. 

 S. Eu. Var. Pallasii, Pax (P. Pdllasii, Lehm. P. 

 altdica, Pall.). Lvs. oblong or elliptic, gradually atten- 

 uate into petiole, nearly glabrous, little or not at all 

 rugose: calyx very narrowly tubular, the lobes very 

 narrow and recurved at apex. Urals, Caucasus, N. 

 Persia, Altai. Var. cordifolia, Pax (P. cordifblia, Rupr.). 

 Lvs. round-ovate, cordate at base, 

 the petiole wingless or narrowly 

 winged, nearly glabrous, scarcely 

 rugose : calyx very narrowly tubular, 

 the lobes very narrow and at apex 

 recurved. Caucasus and Armenia. 



99. pseudoeljttior, Kusn. Differs 

 from P. elatior in calyx-lobes being 

 broad-lanceolate and about equal- 

 ing the length of the tube: Ivs. 

 ovate, hairy, rugose, green beneath, 3187. The cowslip. Primula veris. ( x M) 



abruptly contracted into petiole, the base cordate to 

 truncate: scape exceeding the Ivs., bearing a simple 

 umbel: corolla yellow, with plane limb: caps, rounded, 

 much shorter than calyx. Caucasus. 



100. leucophylla, Pax. Differs from P. elatior in the 

 Ivs. being densely white-tomentose beneath: Ivs. some- 

 what coriaceous, oblong or elliptic, obtuse, rugose, 

 petiolate: scape exceeding the Ivs., pubescent but 

 becoming more or less glabrescent, bearing a many-fld. 

 umbel : corolla yellow, scarcely exceeding the calyx, the 

 limb plane, lobes obcordate: caps, cylindrical, equaling 

 or less than the calyx. Carpathians. 



cc. Fls. violet, rarely white. 



101. amdena, Bieb. Lvs. submembranaceous, some- 

 what roughened or thin, narrowed to the petiole or 

 abruptly and longer petioled, in which case the base is 

 cordate or subcordate, sometimes minutely denticulate 

 or subentire, sometimes decidedly coarse-crenate, ashy 

 tomentose or glabrous below; the petiole equaling the 

 blade: scape 1-5 in. high, exceeding the Ivs., bearing 

 a many-fld. umbel: bracts short-lanceolate, acuminate; 

 fls. purple or lilac, rarely white; calyx narrowly tubu- 

 late, with lanceolate acuminate lobes; corolla-tube 

 cylindrical, the limb flat, %-!} in. across, with obcor- 

 date emarginate lobes: caps, cylindrical, equaling or 

 exceeding the calyx. Caucasus region to Asia Minor, in 

 several varieties. B.M. 3252. 



BB. Scape none or nearly none, the umbels therefore borne 

 in the foliage and the fls. standing singly on the 

 long rays. 



c. Lvs. not white-tomentose beneath. 

 102. acaulis, Hill (P. vulgaris, Huds. P. veris var. 

 acaulis, Linn.). PRIMROSE. Lvs. many, tufted, some- 

 what wrinkled, membranaceous, oblong or obovate- 

 oblong, apex obtuse, gradually rarely evenly narrowed 

 to the petiole which is shorter than the blade, some- 

 times sessile, more or less pilose or glabrescent, crenu- 

 late; the petiole more or less winged: scape none; 

 pedicels 2J^-4 in. long, more or less equaling the Ivs., 

 soft-pubescent, as is the calyx: fls. pale yellow, or rarely 

 purple or blue, becoming greenish in drying; calyx ovate- 

 tubular, 5-ribbed with narrow-lanceolate, acuminate 

 lobes; corolla-tube cylindrical, the limb 

 flat, 1-1J^ in. across, with obcordate 

 emarginate lobes, the throat slightly 

 contracted and bearing a circle of 

 scale-like folds: caps, ovate, included in 

 the calyx. Eu., widely distributed and 

 well known. B.M. 229. Var. rubra, 

 Sibth. & Smith. P.Sibthdrpii, Hoffmg.), 

 has rose-colored or purple fls. E. Medit. 

 region. A. anislaca, Stapf, is a hybrid 

 of P. acaulis and P. elatior. P. Croiissei, 

 Hort., is probably a garden form of 

 P. acaulis or one of the hybrid deriv- 

 atives. For pictures of various forms 

 of P. acaulis or vulgaris, see Gn. 

 7, pp. 319, 345; 11, p. 127; 12:496; 29, 

 p. 385; 54:142, and pp. 

 142, 143. A.F. 13:1102. 

 Gng. 6:245. R.H. 1880: 

 90; 1898: 12. In cult., the 

 primrose runs into many 

 forms and colors, some of 

 them double-fld. More or 

 less caulescent forms (var. 

 caulescens, Hort.) are 

 probably hybrids.

 supposed to be hybrids of 

 P. veris or P. elatior and P. 

 acaulis, although some 

 botanists refer it to P.
