Hoya elmeri Merr., Univ. Calif. Publ. Bot. 15: 258 (1929); Rodda et al., Webbia 69: 44 
(2014). - TYPE: Malaysia, Sabah, Tawao, October 1922 - March 1923, Elmer, A.D.E. 
20652 (lectotype A [A00076433], designated by Rodda et al., (2014: 44); isolectotypes 
BISH, BM, BO, IBSC, MICH, NY, P, SING, U, UC [UC312114], Z). 
Hoya fauziana Rodda, Simonsson & A.L.Lamb, Webbia 70(2): 207 (2015) [8 June 
2015]. - TYPE: Originally from Malaysia, Sabah, Ulu Tomani, 1200 m, cultivated at 
Kipandi Park, vouchered on 30 October 2013 as Lamb, A. 2462/2013 (holotype SAN; 
isotype SING). 
Hoya finlaysonii Wight, Contr. Bot. India 38 (1834); Rintz, Malayan Nat. J. 30: 511 
(1978); Noltie, Bot. Robert Wight 170 (2005). - TYPE: Penang?, herb. Finlayson, 
Wall Asclep. no 42[B = Wall. Cat. 8166B] (lectotype K [K000895121], designated 
here; isolectotypes K [K001129114], E [E00179577]). 
Notes. The occurrence of Hoya finlaysonii Wight in Borneo is doubtful. However, as 
numerous closely related taxa occur in Borneo and although their synonymies have 
not been fully clarified, this name is also typified here. Wight (1834) mentioned the 
materials for Hoya finlaysonii as ‘Wall Asclep. n. 42. Penang?; Wallich and Finlayson’. 
The description did not include a description of the flowers and it is possible that the 
specimens examined were all sterile, as also mentioned by King & Gamble (1908) 
when referring to Kew’s materials of H. finlaysonii. A sterile specimen belonging to 
what used to be Wight’s personal herbarium is present at K and is the most suitable 
lectotype for Hoya finlaysonii (Noltie 2005: 134). Rintz (1978) mentioned a ‘holotype’ 
of Hoya finlaysonii as ‘Malaysia, Melaka, Wight (K)’ but it is impossible to ascertain 
whether [K000895121] is the same specimen as no Wight specimen of the taxon was 
collected in Melaka. Since the specimen is sterile a careful selection of a fertile epitype 
will be needed. The syntype Wall Asclep. no 42[A = Wall. Cat. 8166A] is also present 
at K [K001129113], 
Hoya forbesii King & Gamble, J. Asiat. Soc. Bengal, Pt. 2, Nat. Hist. 74(2): 574 
(1908); Rintz, Malayan Nat. J. 30: 517 (1978). - TYPE: Indonesia, Sumatra, Kaba 
Volcano, 1881, Forbes, H.O. 2896a (lectotype K [K000894730], designated here). 
Notes. Three specimens were cited in the original description of Hoya forbesii , 
Scortechini 1679 & 1680 and Forbes 2896a. The only extant specimen I was able to 
locate is Forbes 2896a (K), which also bears a dissection and a drawing of the flowers 
in Gamble’s hand and is therefore selected as the lectotype. 
Hoya gildingii Kloppenb., Fraterna 15(1): 10 (2002). - TYPE: Originally from
