Primula

Within the last two or three years, a considerable impetus has been given to Primula cultivation, and a large number of new and rare species and hybrids have been introduced to English gardens. Undoubtedly, the most extensive collection is that of the Royal Botanic Gardens, Kew; Mr. D. Dewar-foreman of the Herbaceous Department-who has charge of it, has kindly prepared the following descriptions, and has corrected, from personal observation and study of the plants in a living state, a number of errors common to Primula nomenclature, &c. Those specially interested in Primroses should consult the "Report of the Primula Conference," forming Vol. VII., No. 2, of the "Journal of the Royal Horticultural Society," 1886. The most important of recent monographs is the excellent one of Dr. Pax, of Breslau (1888), entitled "Monographische Uebersicht uber die arten der Gattung Primula."

P. admontensis (Admont). fl., calyx coloured, pubescent; corolla lobes lilac, cordate; scape erect, twice as long as the leaves, few-flowered. May. l. spathulate-ovate, dentate-serrate on the margins, glandular-pilose. Roots tufted. Styrian Alps, 1883. A hybrid between P. Auricula and P. Clusiana, found on limestone rock with its parents. SYNS. P. Churchillii, P. Clusiana dentata.

P. alpina (alpine). fl. brilliant violet-purple, large, in a many-flowered bunch. May. l. broadly spathulate or obovate, slightly toothed, covered, as well as the scape, with farina. Grisons. A hybrid between P. Auricula and P. viscosa, of great beauty, resembling the former in habit and distribution of the flowers. It is suitable for either the rock-garden or the flower-border. SYNS. P. intermedia (of gardens), P. rhoetica.

P. amethystina (amethystine). fl. red-purple, three to six in an umbel; lobes entire or emarginate. June. l. resembling those of a Daisy, ovate-oblong; petioles winged, short, attenuated. Prairies, Yun-nan, China. Plant glabrous, slightly farinose.

P. Balbisii (Baldo). fl. shining golden-yellow, large, almost scentless; throat white, hairy. April and May. Baldo, and the Alps of South Tyrol, Styria, &c. This is distinguished from its near ally, P. Auricula, by its smaller, rounder, and more glossy leaves, which are entirely free of farina, so conspicuous in this section.

P. bella (pretty). fl. violet-purple, two or three on a scape, sub-sessile, very large. Summer. l. long-petioled, ovate or sub-orbiculate. Habit of the Himalayan P. uniflora, but differing in the narrow, deep lobes of the leaves, in the shape of the calyx, and in the corolla, which has bifid lobes, the throat being closed with whitish hairs. Summit of Mount Tsang-Chan, Yun-nan, 1884.

P. bellunensis (Belluno). fl. golden-yellow, large, on longish scapes, handsome, free. May and June. l. broadly ovate, obtuse; veins prominent; margins deeply and evenly serrated or indented, densely ciliated; petioles winged. Alps of Belluno. Said to be a hybrid between P. Auricula and P. Balbisii.

P. bullata (inflated). fl. golden-yellow, large; tube narrow at the throat, but broadening towards the calyx, half as long again as the limb; scapes tall, many-flowered. April. l. petiolate, lanceolate, firm, covered underneath with golden dust, reticulated and slightly inflated above; margins doubly dentate or crenate; petioles winged. Rhizome thick, woody, covered with scars above, divided at the base. Calcareous rocks, Yun-nan. A very beautiful species, almost entirely covered with golden farina.

P. calliantha (beautiful-flowered). fl. intense violet-purple, five to ten in an umbel, large; calyx campanulate, the teeth narrow, purplish on the outside; bracts lanceolate, acuminate. June. l. oblong or obovate-oblong; petioles short, winged and attenuated. Rhizome short and thick. Shady places under Fir-trees on Mount Tsang-Chan, Tali, Yun-nan. A charming species, nearly allied to P. secundiflora, differing in its more coriaceous leaves, covered underneath with a fine, golden powder, and finely crenulate instead of serrulate.

P. carniolica (Carniola). fl. pale to deep blue, with a silvery-white throat; scape 3in. to 4in. high, with from three to ten flowers. April and May. l. 2in. long, ovate-lanceolate, tapering to the base, but again broadening at the clasping point, glabrous, shining on the upper surface. Rosettes large, loose. Alps of Carinthia, and Carniola. SYNS. P. Freyeri, P. Jellenkiana. P. c. multiceps has larger and deeper-coloured flowers.

P. cernua (drooping). l. broadly ovate, short, petiolate; margins crenulate.

A form of P. viscosa hirsuta. P. Delavayii (Delavay's). fl. intense purple, large, slightly hairy on the outside; peduncles eventually 1ft. or more high. August. l. broadly ovate or sub-orbicular, cordate. Damp situations in clayey soil (16,000ft.), Yun-nan, China. A very interesting new species, constituting a new sub-genus on account of the large, laterally compressed seeds, and by the flowers appearing before the leaves, borne singly on bractless peduncles.

P. digenea (two-natured, i.e., hybrid). A hybrid between P. elatior and P. vulgaris, nearly allied to the former. It is not distinct enough for general collections. Alps.

P. Dinyana (Dinyan's). fl. deep purple, handsome, produced in great abundance; corolla lobes narrow-obcordate; scapes 3in. to 6in. high, disposed in rather large heads of four to ten flowers. Spring. l. 4in. long, ovate-lanceolate, with ciliated and slightly dentate margins. Bavaria. A hybrid between P. integrifolia and P. viscosa, most nearly allied, however, to the first parent, from which it takes its habit.

Collected on the Mountain Trate, Indicarien, Austria, 1877. A robust-growing, free-flowering hybrid between P. minima and P. spectabilis, with the characters of both parents distinctly shown in robust specimens. It is pretty for rockeries, doing well wherever P. minima grows. Sandy peat, in rather dry positions.

P. elatior calycantha (calyx-flowered). A pretty, garden form, having a large, leafy, frilled and lobed calyx, which is coloured like the corolla. 1886. (R. G. 1886, p. 242, f. 17.)

June. l. papery, pale green, ovate or ovate-oblong, obtuse, attenuated at base, doubly crenate; petioles narrowly winged. Elevated pastures of Tsang-Chan, above Tali, Yun-nan, 1884. A very remarkable species, with unilateral, spicate flowers, a form of inflorescence unique amongst Primulas. P. Steinii (Stein's). fl. violet-purple, with a white throat, large; scape 1in. to 2in. high, three or four-flowered. April. l. in large rosettes, obovate-spathulate, with seven to nine large teeth at apex, and having thinly-scattered, glandular hairs along their margins. Central Tyrolean Alps, 1878. A hybrid between P. minima and P. viscosa hirsuta, resembling the former in habit. It is a splendid plant for the rock-garden, producing flowers in the greatest profusion, and as robust as in P. Forsteri. P. Stuartii purpurea (purple). fl. pale or deep purple, often in two whorls; lobes obcordate or bifid, entire. Summer. l. rarely toothed, broad, white or yellow beneath. Sub-alpine and Alpine Himalayas. Habit and leaves resembling P. Stuartii. SYN. P. Joeschkiana (of Kerner).

Whole plant 2in. to 2 1/2in. high, glabrous. (G. C. n. s., xxi., p. 545.) P. tenuiloba (slender-lobed). A variety of P. muscoides. P. uniflora (one-flowered). fl. pale lilac, larger than the whole rosette of leaves; corolla lobes shallow, unequally toothed; scape slender, one or two-flowered. l. few, 1/2in. long, orbicular or broadly ovate, pinnatifidly crenate. Sikkim-Himalaya. A charming little species. (G. C. n. s., xxi., p. 545.) P. Venzoi (Venzo's). fl. pale purple, one to three to a scape, 1in. in diameter, very pretty; petals deeply cut. April. l. 1in. to 1 1/2in.long, ovate-lanceolate, pointed; margins rough, cartilaginous, slightly indented; surface hairy and densely pitted. Tyrol, &c. Habit tufty, in dense rosettes. A hybrid between P. tyrolensis and P. Wulfeniana, nearly allied to the latter. P. vinciflora (Periwinkle-flowered). fl. purplish-violet, 1 1/2in. in diameter; tube long, pubescent, swollen at the base; corolla lobes obcordate; scape hairy, one-flowered. l. cuneate-oblong, ciliated, covered with reddish, sessile glands. Yun-nan, China. (G. C. ser. iii., vol. i., p. 575, f. 108.) P. viscosa ciliata (fringed). A very robust form, with larger flowers, produced in greater abundance than in the type.

P. v. commutata (changed). fl. bright rose, large. May and June. l. broadly ovate or obovate, viscous-hairy; margins entire or slightly toothed. Porphyritic region, Eastern Alps.

P. v. confinis (neighbour). fl. bright, deep rose, large, very handsome, approaching those of P. v. ciliata, but larger and more vigorous. May and June. l. small, obovate, toothed, viscous-hairy. Alps. P. v. hirsuta (hairy). fl. pale lilac, with a bright silvery eye, large. Spring. Eastern Switzerland, Tyrol, &c. (6000ft. to 7000ft.). A charming variety, forming large rosettes of ovate or ovate leaves, deeply and sharply toothed, and densely covered with soft hairs. P. decora, of Sims (B. M. 1922), is very nearly allied to this variety, as also is P. pallida. P. v. major (larger). A garden synonym of P. Peyritschii. P. v. Nelsoni (Nelson's). fl. pale purple or pink, many on a scape. April and May. l.obovate, entire or slightly serrated; margins glandular-hairy. Habit of P. viscosa; rosettes neat. Originated in English gardens. P. Wulfeniana (Wulfen's). fl. deep purple-violet, large. April and May. l. not punctate as in P. spectabilis, lanceolate-spathulate, shiny green; margins rough, cartilaginous. Alps. A good and very free rockery plant, requiring calcareous soil. In Vol. III., p. 222, it is placed as a variety of P. spectabilis, but it is quite entitled to specific distinction. P. yunnanensis (Yun-nan). fl. violet-purple; corolla tube narrow, twice as long as the calyx; limb concave, bilobed, the lobes ovate, entire. July. l. ovate-oblong, crenulate, mucronate; petioles short, narrowly winged, glabrous. Clefts of limestone rocks at foot of Li-Kiang Glacier, China. A very fine species, closely allied to P. uniflora.
