Gentiana (Supplement)
To the species described on pp. 59-61, Vol. II., the following should now be added:
G. arvernensis (Auvergne). A beautiful little alpine Gentian, allied to G. Pneumonanthe, but more robust and tufted in habit, with much deeper blue flowers, and firmer and broader leaves. It lasts many weeks in blossom. 1882. Probably a new form of G. Pneumonanthe.
G. Bigelovii (Bigelow's). fl. violet, sessile, axillary, arranged in a leafy spike; calyx tube purplish, cylindric, with long-linear, green teeth; corolla about 1in. long, two subulate teeth alternating with the ovate, sub-acute lobes. August. l. linear or linear-oblong, 2in. long. h. 1ft. to 1 1/4ft. New Mexico, 1886. (B. M. 6874.)
G. decumbens (decumbent). fl. blue, in a racemiform cyme; corolla narrow, obconical, with five short, ovate lobes. l. linear-lanceolate, scabrous on the margins. Stems ascending. Siberia. (R. G. 1087, f. 1-2.)
G. Fetisowi (Fetisow's). fl. deep blue, sessile, in terminal, compact clusters, and solitary or clustered in the axils; corolla tubular-campanulate, the segments slightly acute. July and August. l. narrow-lanceolate, five-nerved, entire; cauline ones connate; radical ones rosulate. Stem solitary, tall, erect. Turkestan, 1883. Plant highly glabrous. (R. G. 1069, f. 1-5.)
G. Kesselringi (Kesselring's). fl. whitish, dotted outside with violet, sub-sessile in glomerate, terminal racemes; corolla tubular-ventricose, the limb of five ovate, spreading lobes, shortly apiculate at apex. July and August. l., radical ones numerous, linear-lanceolate, acute; cauline ones opposite, oblong-lanceolate. Stems about 8in. high. Turkestan, 1883. (R. G. 1087, f. 3-4.) G. Moorcroftiana (Moorcroft's). fl. solitary at the ends of the branches or in leafy cymes; calyx tube 1/4in. long; corolla pale blue, 3/4in. to 1 1/4in. long, funnel-shaped, the throat naked and without folds, the lobes ovate, 1/3in. long. Summer. l. 1in. to 1 1/2in. long, sessile, linear-oblong or elliptic, obtuse or sub-acute, nerveless. Stem simple or branched from the root. h. 4in. to 10in. Western Himalayas. Annual. (B. M. 6727.)
G. Olivieri glomerata (Olivier's compact). fl. deep blue, usually very numerous, sessile or nearly so, densely cymose-subcapitate or in an uninterruptedly glomerate raceme. July. l. as in G. Fetisowi, but narrower. Turkestan, 1883. (R. G. 1069, f. 6-7.)
G. sceptrum (sceptre). fl. deep blue, large, borne in terminal clusters. Stems fleshy, 1ft. to 2ft. high.
G. triflora (three-flowered). fl. blue, large and handsome, somewhat like those of G. Pneumonanthe. Late autumn. l. linear-lanceolate, smooth, glossy dark green. h. 1ft. Mountains of Central Asia. (R. G. 1189.)
G. verna aestiva (summer). A form with larger flowers than the type.
G. Wallichiana (Wallich's). fl. light blue, in axillary, terminal clusters. July and August. Stems 9in. to 12in. long, nearly prostrate.
G. Walujewi (Walujew's). fl. whitish, dotted pale blue, sessile, densely crowded in a head-like, terminal cyme; corolla 1/2in. in diameter, the lobes elliptic-lanceolate, acute. Late summer. l., radical ones numerous, coriaceous, lanceolate, narrowed into short petioles; cauline ones sessile, elliptic or lanceolate, opposite. Stems solitary or twin, growing erect from the rosette of radical leaves. Turkestan, 1884. (R. G. 1140.)
