Names and types of Bornean Hoya 
43 
Notes. Schlechter 13458 is extant in B and is therefore selected as lectotype for Hoya 
glabra. 
Hoya hamiltoniorum A.L.Lamb, Gavrus, Emoi & Gokusing, Sandalcania 19: 32 
(2014). - TYPE: Originally from Malaysia, Sabah, Ulu Tomani, cultivated at Kipandi 
Park, vouchered on 26 Aug 2009 as Gokusing, L. & Lombika, J. in Lamb, A. 1814/2009 
(holotype SAN; isotype SNP n.v.). 
Hoya ignorata T.B.Tran, Rodda, Simonsson & Joongku Lee, Novon 21(4): 509 (2011) 
[29 December 2011], - TYPE: Vietnam. DakLak, Dak Mil, 11 December 1979, Bien, 
L. K. 1072 (holotype HN; isotype MO). 
Hiepia corymbosa V.T.Pham & Aver., Turczaninowia 14(3): 6 (2011). - TYPE: 
Vietnam, Quang Tri prov., Da Krong distr., Ta Rut municipality, A Pul village, 
around point 16°24'29"N 107°01 f 07"E, broad- leaved evergreen forest along rocky 
river canyon composed with shale and sandstone at elev. about 300 m a.s.l., 10 May 
2011, Averyanov, L., Loc, P.K., Hieu, N.Q., The, P.V., Vinh. N.T. CPC 3066 (holotype 
Herbarium of the Center for Plant Conservation, Vietnam, n.v.; isotype LE, n.v.). 
Notes. The monotypic genus Hiepia V.T.Pham & Aver, was published on 28 September 
2011. Examination of the protologue, associated images and detailed photographs of 
the taxon (Pham & Averyanov, pers. comm.) suggest that it is indistinguishable from 
a taxon published as Hoya ignorata T.B.Tran et al. on 29 December 2011. Rodda 
et al. (2014) showed that the taxon belongs to the genus Hoya and since the epithet 
‘corymbosa ’ is unavailable in Hoya the correct name is Hoya ignorata under Art. 11.4 
of the ICN (McNeill et al., 2012). 
Hoya imperialis Lindl., Edwards’s Bot. Reg. 32: sub. t. 68 (1846); Rintz, Malayan 
Nat. J. 30: 501 (1978); Forster & Liddle, Asklepios 56: 24 1992). - TYPE: Herb. 
Lindley ‘Cultivated, from Sarawak via Lowe’s Nursery’, s.d., s.coll., s.n. (lectotype 
CGE [CGE06041], designated here). 
Hoya imperialisLmdl. var. rauschiiRegd, Gartenflora 282 (1855). -TYPE: Gartenflora 
1855: 282. t.134 (erroneously numbered t.130) (lectotype designated here). 
Notes. Forster & Liddle (1992a) mentioned that a lectotype for Hoya imperialis Lindl. 
may have to be chosen from one of the illustrations published by Lindley (however 
no illustration was provided together with the protologue) as no type specimen may 
be extant in BM, K or L (Rintz, 1978). Lucas (2008) traces the Lindley herbarium to 
CGE. There I have found a specimen originally belonging to Lindley’s herbarium that 
is here selected as lectotype for Hoya imperialis. 
Hoya imperialis Lindl. var. rauschii was described as having paler corolla 
lobes than the type. The taxon was described from cultivated material growing in 
Schaffhausen (Switzerland). Original material has not been found and it is possible 
that a specimen was never made. The illustration published concurrently with the 
description is selected as lectotype.
