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 other morphotype (Fig. 3) is distinguished
by its leaflets which are biserrate, glandular and pubescent on both surfaces. All petals and staminodes
are milky-white, the sepals are much shorter, and may also extend into a long (but never dilated)
tip. This rose is apparently only from Van and it is still flourishing on the balcony of Asuman
Baytop’s home in Istanbul where it flowers well after mild pruning.

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.
