NOMENCLATORIAL NOTE ON A 
SOUTH AMERICAN ORCHID 
BY 
CHARLES SCHWEINFURTH 
The following note is the result of intensive studies on 
the orchid flora of Peru. 
Batemannia Colleyi Lindley in Bot. Reg. 20 (18384) 
t. 1714—W..J. Hooker in Bot. Mag. 67 (1840) t. 8818— 
Cogniaux in Martius FI. Bras. 3, pt. 5 (1902) 473, t. 94, 
HesTs 
Lycaste Colley: Hort. ex J.E.Planchon Hort. Donat. 
(1855) 16. 
Mawillaria Colley: Hort. ex J. K. Planchon Hort. 
Donat. (1855) 16. 
Petronia regia Rodrigues Gen. et Sp. Orch. Nov. 1 
(1877) 107. 
Batemania Petronia Rodrigues in Vellosia ed. 2, 1 
(1891) 131. 
Batemania peruviana Rolfe in Kew Bull. (1895) 198. 
Except for Batemania peruviana, all of the foregoing 
concepts have already been reduced to B. Colleyi. 
On the evidence of a photograph of the type of Bate- 
mania peruviana, together with the description, it 1s ap- 
parent that this concept is also reducible to 2B. Colley: 
as beautifully delineated in the Botanical Register, t. 
1714. There is in general no morphological difference 
between these concepts. B. Colley is described and shown 
as having oblong-spatulate lateral sepals, whereas these 
parts are oblong in B. peruviana. However, this ‘‘spat- 
ulate’’ appearance in the case of B. Colleyi is undoubt- 
edly due to the subconduplicate lower portion of the 
lateral sepals—a character which is also ascribed to B.
