When we examined the available herbarium material and the photographs documenting Turhan Baytop's roses, we realised that two morphotypes of the rose exist. The one selected by T. Baytop for the front
cover of his book (reproduced here as Fig. 1) and on p. 114, photo 23 (reproduced here as Fig. 2) has leaves which are uni- or bi-serrate, ± glabrous and eglandular. The sepals are usually prolonged into a slender, up to c. 8 mm long dilated tip. The innermost staminodes of the flower have a golden-yellow longitudinal stripe, imparting an attractive orange glow to the flower centre. The stripe derives from the anthers which are orange or deep yellow in R. beggeriana. The filaments are white.
