Primula auricula, Linn. (Auricula lutea, Opiz). AuricUla. See p. 430 and Fig. 440, Vol. I, and also for cult. Low, with a radical rosette of thick obovate-cuneate glabrous or pubescent mealy lvs. 2 or 3 in. long, which are often crenate on the upper part: scape 1-8 in. high (sometimes nearly or quite wanting), usually exceeding the lvs.: fls. in an umbel, sometimes as many as 20, bright yellow and fragrant or inodorous, short-stalked, subtended by minute oval mealy bracts, the segms. obovate-cuneate and emarginate; stamens dimorphous.—This description represents the wild form as understood by J. G. Baker in B.M. 6837. "It is one of the most widely spread of all the species," Baker writes, "as it extends in a wild state from Dauphine and the Jura on the west through Switzerland to Lombardy, the Tyrol, Hungary, and Transylvania." In cult., the plant has run into fls. of many colors. It is possible that some of these forms are hybrid progeny with related species. Baker writes: "What the relation is of this widely spread wild type to the multiform races of the garden Auricula is a subject that still remains to be fully worked out." The cult. forms are of two groups,—those having farina on the lvs. and those without it. Var. albocinota, Hort. Lvs. densely farinaceous, white-margined. The wild form of the species is little known in cult. MacWatt writes that "by nature it flourishes best where it is most at home, amongst the limestone rocks of the Alps, the Apennines, and the Carpathians. In the wild state the flowers are comparatively small, but under cultivation the scape often carries a big head of large-sized flowers." Var. ciliata, Koch (P. ciliata, Moretti. P. Balbisii, Lehm. P. bellunensis, Venzo), has lvs. not farinose, cartilaginous-margined, more or less glandular-pilose, the edges densely long-ciliate: fls. scentless. Var. Obristii, Beck (P. Obristii, Stein. P. similis Stein. P. Balbisii, Beck). Lvs. silvery green, not mealy, more or less glandular-hairy, the margin cartilaginous and ciliate: fls. fragrant, yellow, the calices and pedicels mealy; May-July.—For dry sunny edges or rocks. ^CH The above text is from the Standard Cyclopedia of Horticulture.
