Knautia pirinica D.Georgieff sp.n.

A key for determination of the new and the closest species:

Knautia pirinica D.Georgieff sp.n.* (Thesis)  - Stem comparatively lower, 15-40(50) см, in uppert 2/3 mixed glandular-eglandular hairy. Capitula singular.  Lower, middle and basal rosette leaves completely glabrous, undivided, subcoriaceous, wide in upper 2/3 of the leaf lamina. The uppermost leaves hairy, rounded at base, broadly cuneate.

Knautia midzorensis Form.  ** (Antithesis) - Stem comparatively higher, 60-120(150) см, hairy. Capitula 3 or rarely 5.  Lower, middle and basal rosette leaves hairy, undivided, subcoriaceous, wide in the middle of the leaf lamina. The uppermost leaves glabrous, cordate.

Knautia pirinica D.Georgieff sp.n. Diagnosis: Perennial high-mountain endemic plant without basal leaf rosette at anthesis. Stem 15-40 (50) cm high, glabrous in lower 1/3 and in the upper 2/3 mixed glandular hairy and with eglandular setulose hairs (glandular hairs short than the eglandular hairs), unbranched, only with an one capitula. Leaves undivided, linear-lanceolate or spathulate, most wide in the upper thirt, subcoriaceous; basal and lower cauline leaves 7-11 times as long as wide, completely glabrous, only the upper leaves with rounded base, amplexicaul with sericeous patent hairs, 2-4 times as long as wide. Peduncles eglandular and glandular hairy. Involucral bracts 9-15 mm long, external broadly ovate, internal lanceolate, acute, long ciliate. Capitula 1, 2-4,5 (5) cm in d. Calyx 8-awned, subpatelliform, 3-5 mm long. Corolla 4-lobed, pink.
Diagnosis: Planta perennis. Caulis 15-40(50) cm lg., infra glabrus, supra setosus, deramificatus. Folia integerima, linearo-lanceolata vel spathulata; folia basalia et caulinaria inferiora glabra; folia suprema villosa, villosa. Pedunculi  eglanduloso et glanduloso villosi.Capitula 1, 2-4a5 cm in d. Calyx cum 8 setae. Corolla pink.
Holotypus: Infra montem Vihren, Pirin, Bulgaria. Planta florenda et fructifera 12.08.2009 l.; 2500 m a.
By leaf indumentum the new species resembles to K. salvadoris, but differs by its solitary flower head on the stem. The new species flowering July and August. From K.longifolia and K. midzorensis the new species differs by its singular capitula on the stem and hairy upper leaves. K.midzorensis and K. longifolia have glabrous upper leaves on both sides and marginally sparsely ciliate.

image image Mountasin flora of Greece, A. Strid, Kit Tan: Upper leaves 6-8 times as long as wideq sometimes widened at base, glabrous on both sides, sparsely ciliate, Knatia midzorensis Formanek have similar leaf indumentum on upper leaves like Knautia longifolia.
Knautia longiflora -
Най близкият вид Knautia midzorensis Form.:
При него листата са влакнести, долните и средните стъблови листа са най-широки в средата, само горните листа са голи.

Hello , I do think this can be a fantastic web site. I stumbled on it on Yahoo , i'll arrive again the moment once again. Cash and liberty could be the finest approach to modify, could you be abundant and aid others.
