03A87264390FFFB5FF4AF8C5FA873524.taxon	etymology	Etymology: — The species epithet issleri honors Emil Issler, from whom Renner received a rosette collected in Colmar (France) and labeled as “ Oenothera muricata ”. A research made by Renner proved the identity of the obtained plants with experimental hybrids “ O. biennis × O. syrticola ”. He named individuals referable to this hybrid phenotype as O. issleri (Renner 1950, 1956). Genetic features: — Number of chromosomes 2 n = 14 (Przywara & Rostański 1980); true-breeding permanent translocation heterozygote (PTH) (Dietrich et al. 1997); catenation figure: ring of 14 chromosomes (Linder 1957); main types of haploid genomes BC (Dietrich et al. 1997), Renner’s complexes combination ♀ rubens - ♂ curvans (Renner 1950, 1956).	en	Woźniak-Chodacka, Monika (2018): Validation of the names Oenothera issleri and O. issleri var. silesiacoides (Onagraceae). Phytotaxa 343 (3): 293-297, DOI: 10.11646/phytotaxa.343.3.11, URL: http://dx.doi.org/10.11646/phytotaxa.343.3.11
03A87264390FFFB5FF4AF8C5FA873524.taxon	distribution	Distribution: — Central Europe (Rostański et al. 2010). According to Rostański, O. issleri grows only in mixed populations of its parental species (Rostański & Fijałkowski 1991). Hybrids: — Rostański & Schnedler (1991) reported one hybrid involving the considered species from Germany: O. issleri × O. biennis. However, experiments made by Linder (1957) proved that the result of such hybridization is negative because it leads to the lethal combination of Renner’s complexes: rubens-rubens (Linder 1957). Paratypes: — POLAND. Dolnośląskie: Wrocław, [cultivated in Botanic Garden from seeds collected from the Main Station], 51 ° 06 ʼN 17 ° 02 ʼE, 117 m, 4 July 1962, Rostański 17 / 61, [a single specimen mounted on 4 sheets (WRSL 4010119 – 22!)]; [cultivated in Botanic Garden from seeds collected by F. Schötz from Renner’s collection in Monachium], 51 ° 06 ʼN 17 ° 02 ʼE, 117 m, 15 July 1964, Rostański 26 / 63, [a single specimen mounted on 2 sheets (WRSL 4010125 – 26!)]. Variability: — One phenotypic variant has been formally described as a variety, O. issleri var. silesiacoides Rostański & Jehlík in Jehlík & Rostański (1979: 424), which differs from the type variety by a dark red (vs. white) coloration of midribs and the lower part of the stem. However, in accordance with Art. 35.1 (McNeill et al. 2012) the varietal name was not validly published because the species name had not been validly published by that time. Previously, in his unpublished PhD thesis Rostański (1963) considered these two variants under different names: O. issleri var. albinervis (with white midribs) and var. rubrinervis (with red midribs) but in 1979 he renamed the redcolored variety and treated the white-colored variety as the type one.

Oenothera issleri Renner ex Rostański var. silesiacoides Rostański & Jehlík (1979: 424), nom. inval. (Art. 35.1, McNeill et al. 2012; published without validation of the species name).	en	Woźniak-Chodacka, Monika (2018): Validation of the names Oenothera issleri and O. issleri var. silesiacoides (Onagraceae).
