ered an isotype specimen of Aerides rigida, even if we, as 
explained above, undoubtedly must consider Buchanan- 
Hamilton’s drawings as the holotype. 
It might be noted here that my Harvard colleague, Dr. Garay, 
located in the British Museum another drawing representing an 
Acampe, labelled ‘‘Dr. Hamilton’? and numbered 397 which has 
a series of names by different hands: ‘‘A. striatum Wall. 
(Epidendr. Hamilton)’, ‘‘Aerides praemorsum?’’, *‘Vanda 
sp.?”’, and ‘*?Saccolabium papillosum’’. | believe this drawing 
also represents the Rigid Air-Blossom, Aerides rigida. 
When considering Vanda multiflora described and illustrated 
by Lindley in his ‘“‘Collectanea Botanica” t. 38, January 1826, 
we get to a critical phase of the history. The plant in question, 
which was said to come from China, flowered in Mr. Cattley’s 
conservatory in July 1822, and Lindley had a drawing made of it. 
Dr. Garay sent me a photograph of the original engraving for the 
plate t.38, which ts in the British Museum, pointing out that the 
engraved name on the drawing is Sarcanthus praemorsus 
(Roxb.) Lindl. 
This particular combination was first used in print by Lindley 
in the tenth edition of James Donn’s *‘ Hortus Cantabrigiensis’’, 
published in March 1823. It was entered as anomen nudum and 
stated that the plants had been introduced from China in 1800. 
This must be the same specimen as mentioned in the ninth 
edition (1819) of *‘Hortus Cantabrigiensis’’ under the name 
Cymbidium praemorsum (with a reference to Roxburgh’s plate 
in Coromandel) even if that one was said to have been intro- 
duced from ‘‘E. Indies’’ also in 1800. It is clear that Lindley in 
1822 and 1823 believed that the Chinese plant was Thalia 
Maravara. In August 1824 (Bot. Reg. 10, sub t.817) Lindley gave 
a generic description of the new genus Sarcanthus, which he 
typified by Cymbidium praemorsum (Roxb.) Willd., 1.e., Thalia 
Maravara. 
Before the publication of Plates 38 and 39 of ‘‘Collectanea 
Botanica’ in January 1826, Lindley had changed his mind on 
two highly important points. 
First, he decided that the drawing of the plant from Mr. 
Cattley’s garden was not Thalia Maravara, and he had the name 
Sarcanthus praemorsus erased from the copper plate and substi- 
tuted the name Vanda multiflora. In the Ames Orchid Her-
