moving Rheede’s plant to Saccolabium, Lindley should have 
made the combination Saccolabium praemorsum, but he did not 
due to its having been pre-empted in another manuscript of his 
already in press, which, however, did not appear until May 1833 
(Gen. and Sp. Orch. Pl. pt. 10: 221). According to the Interna- 
tional Code of Botanical Nomenclature Lindley’s Saccolabium 
papillosum is illegitimate because at the time of publication the 
combination Saccolabium praemorsum Was available. In trans- 
ferring the epithet to Acampe in 1853, Lindley did not make 
things better for he still ignored Epidendrum praemorsum as a 
name-bringing synonym. 
It may be noted parenthetically that Hooker (1890: 63) ac- 
cepted Saccolabium papillosum, but excluded Thalia Maravara 
(for the latter he proposed the transfer Saccolabium praemor- 
sum (Roxb.) Hook.f.), all in accordance with the then valid Kew 
Code. 
Lindley in his ‘‘Genera and Species of Orchidaceous Plants” 
(p. 215) describes another Vanda species belonging to this com- 
plex, Vanda longifolia Lindl., which he based ona plant brought 
from Tavoy by Wallich. Here we are on safe ground because 
Lindley clearly indicates that his type-specimen is Wallich No. 
7322, still kept in the Herbarium at Kew. Vanda longifolia has 
been maintained up until recently under the name of Acamipe 
longifolia (Lindl.) Lindl., although with varying taxonomic con- 
tent. 
Some years later (Bot. Reg. 25: Misc. p. 61, 1839) Vanda 
congesta was added to this interrelated complex by Lindley 
based on a plant from Ceylon. When listing this taxon in his first 
enumeration of Vanda species (Paxt. Fl. Gard. 2: 21, April 1851) 
Lindley seems to have reached the opinion that the plant was 
identical with already discussed Saccolabium papillosum be- 
cause he lists it as a synonym together with all previous 
synonyms given in 1833, instead of using the earliest available 
epithet from Epidendrum praemorsum., 
Lindley, however, did not insist that in Vanda congesta he 
just had a new name for Thalia Maravara. In ‘* Folia Orchidacea 
Acampe”’ he states that he had mixed up his specimens and that 
Vanda congesta is something different from Saccolabium papil- 
losum. This opinion has been sustained by Hooker (1890: 63), 
although with some hesitancy regarding the circumscription of 
his transfer, Saccolabium congestum (Lindl.) Hook f.
