SPECIES PLANTARUM — FLORA OF THE WORLD (2002)
There is evidence pointing to an alloploid origin of subsp. hibernica following hybridisation
between L. pallescens and L. campestris; see J.Kirschner, Folia Geobot. Phytotax. 30:
283–290 (1995).

Hybrids
Luzula alpina Hoppe × L. multiflora (Ehrh.) Lej.
A hybrid, sterile plant between a partially agmatoploid and a tetraploid parent
(2n=28=20AL+8BL) was observed and collected in Austria [Hohe Tauern, Grossglockner,
15 Jun 1953, M.Palm, cultivated by H.Nordenskiöld H1-1 (UPS)], and studied by
H.Nordenskiöld (unpubl.).
Luzula ×danica H.Nordensk. & Kirschner, Preslia 63: 109 (1991) = Luzula congesta
(Thuill.) Lej. × L. multiflora (Ehrh.) Lej.
T: Denmark, between Gram and Ribe, H.Nordenskiöld MT-3, holo: UPS.
A hybrid known from Great Britain, Denmark and Sweden; seldom among parental plants.
Fertile.
Luzula campestris (L.) DC. × L. pallescens Sw.
Hybrid plants rarely found between parents, up until now observed in Sweden only. Probably
fertile.
Luzula ×bogdanii Kirschner, Preslia 63: 105 (1991) = Luzula campestris (L.) DC. × L. fallax
Kirschner
T: Bulgaria, the Pirin Mtns, Rozhen, Vlashkija Put, J.Kirschner L117; holo: PR; iso: LD, PRA.
At the places of contact between the parental species, the hybrid may form large populations.
Up to now known from S Bulgaria. It is almost normally fertile and includes a number of
hybrid karyotypes with mixed AL and BL chromosomes.
Luzula ×media Kirschner, Preslia 63: 107 (1991) = Luzula divulgata Kirschner ×
L. multiflora (Ehrh.) Lej.
T: [Czech Republic] Bohemia, Rakovník, Nový Mlýn, silva Brabečka, 16 Jun 1987, J.Hašková, J.Kirschner &
F.Krahulec; holo: PR; iso: PRA
