Hoya jiewhoeana Rodda, A.L.Lamb & Gokusing, Guide Hoyas Borneo 198 (2016) 
[2 May 2016] (as ‘jiewhoeiana’). - TYPE: Originally from Malaysia, Sabah, Tawau, 
Kalabakan area, local collector, cultivated in Sabah, vouchered on 17 January 2016 as 
Bosuang, S. & Gokusing, L. in Lamb, A. AL2747/2016 (holotype SAN; isotype SING). 
Hoya kastbergii Kloppenb., Fraterna 16(4): 1 (2003). - TYPE: Malaysia, Sarawak, 
Bau, Kastberg, A. (holotype UC, missing). Malaysia, Sarawak, Near Mulu National 
ParkH.Q., 23 March 1981, Collenette, I.S. 2357 (neotype L [L2726571], designated 
here; isoneotype K). 
Notes. The type specimen of Hoya kastbergii was indicated only as ‘UC 102003’. 
The specimen in UC barcoded [UC 102003] belongs to Erigeron glacialis (Nutt.) A. 
Nelson var. glacialis (Pia Nutt pers. comm.). It is possible that ‘102003’ may be a 
collection date (October 2003) and not a barcode. See Hoya nyhuusiae below for a 
similar case. No other specimen of Hoya kastbergii is present in UC and since no 
collection information apart from the collector name and the UC barcode was provided 
in the description of the taxon it is impossible to identify isotypes that may be present 
in other herbaria. To fix the application of the name I have therefore selected another 
specimen matching the original description, Collenette 2357 (L) as neotype of H. 
kastbergii. 
Hoya kipandiensis Gavrus, A.L.Lamb, Emoi & Gokusing, Sandakania 19: 42 (2014). 
-TYPE: Originally from Malaysia, Sabah, central Crocker Range, Mongkusilad River, 
nr. Kg. Kipandi, cultivated at Kipandi Park, vouchered on 25 Jan 2010 as Gokusing, L. 
in Lamb, A. 1909/2010 (holotype SAN; isotype SNPn.v.). 
Hoya kloppenburgii T.Green, Fraterna 14(2): 11 (2001). - TYPE: Originally from 
Malaysia, Sabah, Nabawan, cultivated in USA, Hawaii, Oahu, Ka‘a‘awa, vouchered 
on unknown date as Green, T. 97057 (holotype BISH [BISH1014779]). 
Hoya lacunosa Blume, Bijdr. FI. Ned. Ind. 16: 1063 (1826); Rintz, Malayan Nat. J. 
30: 490 (1978). - Otostemma lacunosum (Blume) Blume, Rumphia 4: 30 (1849) [late 
October 1849]. - TYPE: [circa Buitenzorg at arbores] Hoya lacunosa, s.d., s.coll., s.n. 
(lectotype L [sheet number 898168-188], designated here). 
Notes. The only specimen belonging to Hoya lacunosa Blume that can be referred to 
Blume is sheet number 898168-188 (L) that bears an autograph label ‘ Hoya lacunosa'. 
Blume left Java in 1826 and returned to the Netherlands (Van Steenis-Kruseman, 
1950). Therefore the specimen, if collected by Blume, is likely to have been collected 
before the publication of the Asclepiadaceae account in the Bijdragen (Blume, 1826) 
and is therefore a suitable lectotype for Hoya lacunosa. 
Hoya lambii T.Green, Fraterna 13(2): 2 (2000). - TYPE: Originally from Malaysia, 
Sabah, cultivated in USA, Hawaii, Oahu, Ka‘a‘awa, reputedly vouchered on unknown 
date as Green, T. 9905 (holotype BISH, not found). Originally from Malaysia, Sabah,
