Names and types of Bornean Hoya

Typification of recently published names 
Twenty new Hoya names listed here have been published since 1995 in Fraterna, 
the bulletin of the International Hoya Society, and two (Hoya ranauensis T.Green & 
Kloppenb. and Hoya amoena Bakh.f. subsp. bogorensis T.Green & Kloppenb.) in the 
online journal Hoya New (http://www.rare-hoyas.com/publication.htm). As already 
mentioned by Forster (1991) in relation to taxa from the Philippines published by the 
same authors, their style of type citation may be confusing as it often includes only a 
number and the herbarium where the holotype is deposited. Frequently not explicitly 
referred to a collector, this number may be a sheet number, a collector number or the 
collection date of the specimen (see Rodda, 2015b). Without a full citation of the 
holotype, simple citation of a number may refer to multiple specimens belonging to 
different collectors. This is not strictly needed for valid publication but recommended 
by ICN Art. 40A.3. (McNeill et al., 2012). I have therefore examined all holotypes or 
specimens labelled as such in the herbaria where holotypes were deposited, matched 
them against the protologue and provided a full citation that is corrected in case 
mistakes were noted in the protologue. Herbarium acronyms followed by a number 
are here interpreted as sheet number (e.g. UC102003 for Hoya kastbergii Kloppenb.) 
but may potentially be dates as well (see below H. walliniana Kloppenb. & Nyhuus 
and H. nyhuusiae Kloppenb.). Holotypes of six species have not been found. For three 
names, Hoya clemensiorum T.Green, H. lambii T.Green and H. monetteae T.Green, 
specimens made by the publishing author and labelled as neotypes by him have been 
found, suggesting that the holotype is indeed missing or was never actually made. 
The list of names 
Hoya acicularis T.Green & Kloppenb., Fraterna 15(4): 7 (2002). - TYPE: Originally 
from Malaysia, Sabah, Danum Valley, cultivated in USA, Hawaii, Oahu, Ka‘a‘awa, 
Green Plant Research, vouchered on 24 January 1991 as Green, T. 93031 (holotype 
BISH [BISH1000875]). 
Hoya aeschynanthoides Schltr., Bot. Jahrb. Syst. 40 (Beibl. 92): 13 (1908). - TYPE: 
Indonesia, Borneo, Koetei, auf Baumen am Long Dett, August 1901, Schlechter, R. 
13550 (lectotype B [B100277178], designated here). 
Notes. Schlechter (1908) mentioned only Schlechter 13550 for Hoya aeschynanthoides 
Schltr. A single duplicate bearing buds and a drawing of dissected flower parts has 
been found in B [B100277178] and it is therefore selected here as lectotype of H. 
aeschynantho ides . 
Hoya australis R.Br. ex J.Traill, Trans. Hort. Soc. London 7: 28 (1830); Hill, Telopea 
3: 250 (1988); Smith, FI. Vit. Nova 4: 118 (1988); Forster & Liddle, Austrobaileya 3: 
508 (1991); Liddle & Forster, Asklepios 102: 6 (2008). - TYPE: Australia, Queensland, 
Cook District, Cape Grafton, 1770, Banks, J. & Solander, D. s.n. (lectotype BM 
[BM001040528], designated by Hill (1988)).
