Primula obconica, Hance (P. poculiformis, Hook.). Fig. 3182, and Plate XCII. Slender, with loose-hairy lvs. (the sharp hairs often irritating-poisonous): lvs. all radical, ovate-oblong or round-oblong, base more or less cordate, long-petioled, scallop-toothed and very finely serrate: scapes many, 4-10 in. tall, exceeding the lvs.: bracts small, linear, and unequal: fls. small, lilac or light purple, several to many in umbels, on long-spread ing or somewhat drooping pedicels, the segms. obcordate; calyx wide open and shallow-toothed. China. B.M. 6582. Gn. 26:206 and p. 206; 29, p. 241; 51, p. 317; 60, p. 416; 61, p. 271; 72, pp. 190, 255; 77, p. 630. G.C. III. 9:401 (house); 35:245; 40:208; 47:28. G.M. 44:51. Gn.M. 2:228. G. 7:889; 20:33; 28:128, 129; 32:321. C.L.A. 2:233. R.H.S. 39:144. Gt. 43, p. 138. F.R. 1:941.—Of late years this species has become a popular winter-blooming pot-plant. The fls. are nearly or quite an inch across in well-grown specimens. There is a var. grandiflora, Hort., with fls. nearly or quite 1 1/2 in. across. Gn. 51:316; 74, p. 200. J.H. III. 60:196. G.W. 3, p. 109. R.H. 1892, p. 114. Gt.46, p. 193. S.H. 2, p. 52. A.F. 13:1063; 18:43. Gng. 6:245. Some of the large-fld, forms have somewhat lacerated or fringed petals (var. fimbriata, Hort.); var. rosea, Hort., has rose-colored fls.; var. semi-plena, Hort., has partially doubled fls. (G.M. 46:206); var. superba, Hort., is a large-fld. race in different colors. (R.H. 1906:448); var. undulata, Hort., has crisped or undulate fls. (R.H. 1914:300).—Intro. 1880. For history, see Hill, Journ. Genetics, Vol. 2 (1912). P. obconica is very easily grown. Prop. by seed. Persons liable to poisoning by the hairs of P. obconica should rinse the hands or exposed parts in alcohol, then wash with soap and water.A number of very recent species closely allied to P. obconica are likely to find their way into cult. and perhaps to extend the usefulness and range of this type of primula. Some of these species are: P. ambita, Balf. f., a glabrous type from a dry site, with a remarkable involucre; P. barbicalyx, C.H. Wright, hairy all over and with a bearded calyx, the lvs. somewhat elongated and with rounded lobes; P. oreodoxa, Franch., in which the characters of P. barbicalyx are more emphasized (the plant cult. under this name is said to be P. saxatilis); P. begoniaeformis, Petitm., smaller than P. obconica and less hairy; P. parva, Balf. f., very dwarf, xeromorphous; P. Vilmoriniana, Petitm., very hairy, lvs. 2—3 times usual size, scapes short, fls. minute; P. Petitmenginii, Bonati, a grotto plant, lvs. large, membranous, and delicate, scapes very short.
