Names and types of Bornean Hoya 
39 
=Dischidia villosa nom. nud. (based on L sheet [L0004319, L0004320]). 
Notes. Kleijn & Van Donkelaar (2001: 469) selected sheet no. 898.168-121 (L) as 
lectotype of Hoya coronaria Blume. This is one of three sheets annotated ‘ Hoya 
coronaria BT in Blume’s hand. It must be noted that both sheet no. 898.168-121 and 
sheet no. 898.168-128, despite being specimens seen by Blume, cannot be directly 
linked to the protologue of the taxon. The syntype sheet no. 898.168-124 instead has 
a label in Blume’s handwriting where, among undecipherable words, is the common 
name ‘Kilampahan’ and on a different label in Reinwardt’s handwriting the possible 
variant ‘Tjilampahan’, in agreement with Blume’s protologue. 
Another syntype of Hoya coronaria is the illustration of Corona Ariadna, published in 
Rumph. Amb. 5. t. 172. 
The synonymy of Hoya coronaria is complex and a taxonomic revision of 
Hoya section Eriostemma Schltr. is required before a complete list of synonyms can 
be given. The Bornean Eriostemma obtnsifolioides Gilding & T.Green, however, is 
indistinguishable from H. coronaria so is included here. Eriostemma is nested within 
Hoya but can be recognised at the sectional level ( Hoya sect. Eriostemma) (Wanntorp 
et al., 2006a, 2006b, 2011, 2014; Rodda & Ercole, 2014; Rodda et al., 2014). The type 
of Eriostemma obtnsifolioides was only mentioned as ‘Bishop 736375 and ‘Ex hort. 
97048TG, Apinapin, Sabah, Malaysia’. The code ‘97048TG’ was not found on the 
type sheet. Type citation has been here amended. 
Hoya corymbosa Rodda & Simonsson, Syst. Bot. 38: 1126 (2014). - TYPE: Originally 
from Malaysia, Sabah, Sipitang District, Mt. Rimau area, cultivated in Kipandi Butterfly 
Farm, vouchered on 18 June 2009 as Gokusing, L. et al. All803/2009 (holotype SAN). 
Hoya cumingiana Decne. in A.DC., Prodr. 8: 636 (1844). - TYPE: Philippines, 
Luzon, Batangas, s.d., Cuming, H. 1480 (lectotype P [P00639839], designated here; 
isolectotypes BM, C [C10006728], CGE (2 sheets), E [E00288755], G, G-Boiss (2 
sheets), K [K001044838, K000911123], L [L0004322]). 
Notes. In describing Hoya cumingiana , Decaisne (1844) mentioned a single gathering, 
Cuming 1480, kept in Delessert’s herbarium ‘v.s. in herb. Delessert’. Delessert’s 
herbarium was merged into G (Stafleu, 1970) where, however, I could not find any 
Cuming 1480 specimen clearly labelled as originating from Delessert’s herbarium. 
A suitable specimen from Delessert’s herbarium is instead present in P [P00639839], 
being a well-preserved fertile specimen and is here selected as lectotype for Hoya 
cumingiana. 
Hoya curtisii King & Gamble, J. Asiat. Soc. Bengal, Pt. 2, Nat. Hist. 74(2): 563 
(1908); Rintz, Malayan Nat. J. 30: 505 (1978). - TYPE: Malaysia, Perak, Waterloo, 
October 1892, Curtis, C. 2894 (lectotype SING [SING0059475], designated here; 
isolectotypes SING [SING0059474], K [K000895130]).
