DACTYLORHIZA TRAVNSTE1NERI (SAUTER) SOO IN EAST CORK, MID CORK, OFFALY, MEATH, LEITRIM AND EAST MAYO

Specimens in the herbarium which had been tentatively named Dactylorhiza traunsteineri were sent to Mr Peter Hunt, Kew, with the hybrid D. X kellerana. He has

now determined the following collections as D. trausteineri (Sauter) Sod. The orchid had not been previously recorded from the botanic divisions named. The specimens are as follows:

Mid Cork (H4): in wet meadow, marsh south of French's Road, SE of Nad, W4588.

21/7/1969. M. Scannell. East Cork (H5): marsh near the river, NW of Dungourney. 16/7/1969. W.9181. M.

ScanneU.

Offaly (H 18): in fen, "site of Lough Coura", 5 miles south of Cloghan. N 0912. 23/6/1968. M. Scannell.

Meath (H 22): flush W side of Commons, Duleek, Co. Meath. O 06. 28/6/1966. D. Synnott. Leitrim (H 29). Glenade. G 84. 16/6/1959. M. Scannell. East Mayo (H26): amongst Schoenus nigricans tussocks (with the hybrid, D. X kellerana),

west of Keel Bridge, NW of Ballinrobe. M 1567. 29/7/1971.

DACTYLORHIZA X KELLERANA P. F. HUNT IN WESTMEATH AND EAST MAYO

A study by P. F. Hunt on the taxonomy and nomenclature of European orchids is

published in The Orchid Review (1971). One of the hybrids Dactylorhiza X kellerana (Dactylorhiza fuchsii X D. traunsteineri) is of Irish interest.

The first recorded recognition of the hybrid in Ireland was made by J. Heslop Harrison (Watsonia, 2: 376, 1953) from the east side of the Scraw Bog, Co, Westmeath (H23). The plant was not referred to by specific epithet as one was not then available. The hybrid was reported from Wales by R. H. Roberts, from the Cors Erddreiniog National Nature

Reserve at Pentraeth, Anglesey. Material for herbaria had not been collected in either

case. Thus in drawing up the description, Hunt had no specimen to designate holotype to

accompany the new hybrid name as is obligatory according to the International Code of

Botanical Nomenclature. A photograph of the Welsh plant was selected as the holotype. Hunt has indicated that a specimen will be preserved later as the "topotype".

The publication of the hybrid prompted the seeking of the plant during 1971 field work. The following collections were made:

Westmeath (H23): Scraw Bog, NW of Mullingar. N4258. 24/7/1971. M. Scannell. East Mayo (H 26): with both parents, in tussocks of Schoenus nigricans, Keel Bridge, NW of

Ballinrobe. M1567. 29/7/1971. M. Scannell. The identification have been verified by P. F. Hunt, Royal Botanic Gardens, Kew.

The specimens have been added to the Herbarium (DBN). The specific epithet honours

George Keller, the Swiss orchidologist. M. J. P. SCANNELL.

REVIEWS

Supplement to the Vascular Section of the Second Edition of a Flora of the North

East of Ireland. Compiled by Mary P. H. Kertland with t^e assistance of Doreen S. Lambert.

The last edition of Stewart and Corry^s Flora appeared in 1938, edited by Dr Praeger.

Its 532 stiff-bound pages cost 10/6. An age seems to have passed and most of its

contributors have gone. The 48 pages of this booklet are therefore evidence of what the

subsequent generation has achieved. Who most of them are is set out in the Introduction?

31 in 34 years. Even of this small band some are gone, notably Praeger himself and A. W.

Stelfox, and of my generation, Jack Moon.

This supplement is set out in the same style, basis and sequence as its progenitor? would that there had been page references to it. There is little evidence in supoort of the

entries?not even all fie relevant papers in this Journal are quoted. Nevertheless, here

are hundreds of records industriously assembled. Many of these are, or would be, important,

e.g., Thalictrum alpinvm, Scabiosa columbaria and Luzula pallescens are not in the Atlas

even though the first two were found well before it came out. Here too can be found further

detail, such as for Trichomanes speciosum (called 7\ radicans in defiance of the principle
