Changes in the Vandeae


Orchid Hybrid Registration Advisory Group News Release  May 2013


At a meeting of the Royal Horticultural Society’s Orchid Hybrid Registration Group (OHRAG) in London on 22nd May, the proposed nomenclatural changes in the Vandeae were discussed. The Group were privileged to receive seminar presentations by André Schuiteman and Lauren Gardiner, both from the Kew Herbarium, on their research into the taxonomy of the Vandeae.

A full account is due to be published in volume 6 of Genera Orchidacearum which is scheduled for publication in February 2014, and is the final volume of the series.

The members of the Advisory Group unanimously recommended adoption of the following changes in the Hybrid Register immediately.

Vanda is to be expanded to include: Ascocentropsis, Ascocentrum, Christensonia, Eparmatostigma, Euanthe, Neofinetia and Trudelia


Aerides flabellata has been transferred to Vanda

Papilionanthe is to be accepted as distinct from Vanda

Arachnis to include: Armodorum and Esmeralda

Gastrochilus to include: Haraella

Holcoglossum to include: Ascolabium and Penkimia

Phalaenopsis to include: Doritis, Kingidium, Lesliea, Nothodoritis, Ornithochilus and Sedirea

Renanthera to include: Ascoglossum, Porphyrodesme, and Renantherella

Robiquetia to include: Abdominea, Malleola, India, Megalotus and Samarorchis

Trichoglottis to include: Ceratochilus, Staurochilus and Ventricularia.

In the past it has been the custom to await publication of the relevant volume of Genera Orchidacearum and wait for six months to allow discussion, before implementing any nomenclatural changes. On this occasion however, it seemed appropriate for implementation to proceed due to the uncontroversial nature of the changes, and in order to have all the changes in place before data is extracted from the register to prepare the forthcoming Sanders List Addendum. It is hoped this will prevent unnecessary delay in publication of the Addendum. In addition, Doritis and x Doritaenopsis have already been moved into Phalaenopsis.
