Sperlingia tetraphylla nom. mid. annotation on [Cl0006736]. 
Hoya albens nom. nud. in Miller, Bristol Nursery Cat. 55 (1826). 
Hoya lanceolata Donn, Hort. Cantabrig., ed. 2: 92 (1826), nom. nud. non Hoya 
lanceolata Wall, ex D.Don (1825). 
Notes. The specimen here selected as lectotype of Hoya verticillata was indicated by 
Veldkamp et al. (1995) as the holotype. This requires a correction to lectotype under 
ICN Art. 9.9 (McNeill et al., 2012). A possible isotype is present at C [C10006736]. 
It bears the same annotation on the back of the sheet as the lectotype. However, 
‘CynanchumV has been crossed out and substituted with Sperlingia tetraphylla , a 
nomen nudum and I therefore doubtfully refer to it as an isotype. 
Hoya acuta Haw. was described by Haworth based on a sterile live plant 
cultivated in Kew ‘ Vidi crescentem sine floribus in region horto Kewense A.D. 1819’. 
Following Traill (1830) and Veldkamp et al. (1995), Hoya pallida Lindl., Hoya acuta 
Haw., and the nomina nuda Hoya lanceolata and Hoya albens, may all represent 
the same plant, sent as a live specimen to K by Wallich and then spread to various 
gardens in the UK. Since no original material is available for Hoya acuta the name 
is neotypified by a specimen deposited in K that bloomed in ‘Hort Liv’ (Liverpool 
botanic garden?) in 1825, likely originating from the same Wallich stock. 
Hoya pallida Lindl. was likely based on the same live plant as for Hoya acuta 
(Traill, 1830; Veldkamp et al., 1995) but cultivated in the garden of the Duke of 
Northumberland. The only original material available is the illustration published in 
Lindley (1826: 11, t. 951) that is selected as the lectotype. The neotype of Hoya acuta 
is also selected as an epitype of H. pallida. Another specimen, also labelled Hoya 
pallida that was obtained from cultivation in Chatsworth in 1850, is present in CGE. 
The specimen [BM001014257] was indicated as the holotype of Hoya 
nicobarica R.Br. ex J.Traill in Veldkamp et al. (1995) and is here considered as an 
effective lectotypification following ICN Art. 9.9 (McNeill et al., 2012).
