When Lindley published his account of the genus Acampe in 
his ‘“‘Folia Orchidacea’’, he described A. dentata as a new 
species. Apparently he overlooked his earlier described Sac- 
colabium ochraceum Lindl. (Bot. Reg. 28: Misc. p. 2, 1842) for 
Hooker discovered them to be conspecific. In the genus Acampe 
the correct name is A. ochracea (Lindl.) Hochr. 
Among Wight’s Icones (1851) there are two representatives of 
the group. The first is No. 1670, called Vanda Wightiana Lindl. 
mss., Which is based on a fruiting specimen in the Lindley 
Herbarium at Kew. Lindley transferred it to Acampe Wightiana 
(Lindl.) Lindl. (Fol. Orch. Acampe 2, 1853), but according to 
Blatter and McCann it is conspecific with A. praemorsa. Thus, 
in Wight’s plate we have another illustration of Thalia Marav- 
ara. The second illustration is Wight’s No. 1672, called Sac- 
colabium papillosum, but Hooker believes it to be the same as 
A. congesta as was mentioned above. 
When Lindley established the genus Acampe he undoubtedly 
coined the generic name after ‘“The Rigid Air-Blossom”’ in using 
the Greek word akampes, meaning rigid. Reference has already 
been made to most of the taxa listed there. In addition to 
Acampe dentata mentioned above, the list contains two 
additional new taxa. One of them, Acampe excavata Lindl. is 
reduced by Hooker toa synonym of Saccolabium praemorsum, 
while Acampe cephalotes from Sylhet is maintained by him 
under Saccolabium cephalotes (Lindl.) Hook. f. 
Reichenbach, in Walper’s Annales 6: 872-874, 1864, repro- 
duces verbatim Lindley’s treatment from 1853. His A. inter- 
media from 1856 is of some interest because, as far as I can see, it 
is identical with what I have called A. longifolia; another of his 
species, A. Griffithii from 1872 appears to be referable to A. 
ochracea. In 1881, Reichenbach published A. pachyglossa and 
A. Renschiana from Africa. These were later followed by A. 
madagascariensis and A. mombasensis by Kraenzlin in 1891 
and Rendle in 1895, respectively. The African species, including 
A. nyassana Schltr. from 1915 have been studied, as mentioned 
earlier, by Senghas (1964). They are of special interest because 
they seem to be so close to A. longifolia as to appear to be 
conspecific. 
Several references have already been made to Hooker's out- 
standing work of Flora of British India in 1890. I wish to add at 
this point that Hooker seems inclined to combine Lindley’s A
