Series Hayneani Tratt

Series Hayneani Tratt.

The name of the series Hayneani Tratt. (1823) is not illegitimate and, as I already argued in 1974, must be used for the series that is often called Rhamnifolli. The fact that it contains Rubus fruticosus L. does not make it retrospectively illegitimate (see under series Suberecti).

There is another reason why the name Rhamnifolii should not be used for this series. The type of this series, Rubus rhamnifolius Weihe & Nees, does not belong to the series as it has been conceived by e.g. Focke (1877) and Weber (1985; 1995). In the protologue Weihe & Nees mention R. thuillieri Steudel as a synonym. According to Weber (1977) this is a mere reference to R. thuillieri ssu Steudel. The fact, however, is that Steudel is exactly the author of this name. His reference is the validation of the provisional name by Poiret. Poiret (1816) writes that Desfontaines thinks that this plant is a separate species, which not means that he himself does so. On the contrary, he does not give it a number in his sequence. Next to that he does not say that he gives it the name R. thuillieri, but that in case one would follow Desfontaine one could give it the name R. thuillieri. So this is a case of ICN art. 36.1a: the author himself does not accept the name.  It is only validated by the quotation by Steudel.

R. thuillieri is a nomen novum for R. tomentosus Thuill. non. Borkh. The type is in GE (herb. Delessert, Collection de J.-L.Thuillier). It is a specimen with double flowers of a taxon which has been later described as R. linkianus Ser. So its full synonymy is: R. thuillieri Poir. ex Steud. = R. tomentosus Thuill.non Willd. nec Borkh. = R. rhamnifolius Weihe & Nees = R. linkianus Ser.

This species belongs to the series Candicantes and consequently the series Rhamnifolii Focke is a synonym of the Candicantes.
