Notes. The protologue of Hoya nyhuusiae Kloppenb. states ‘(UC) Torill Nyhuus #2003 
ex hort. Torill Nyhuus, Sweden. From Mt. Kinabalu, Sabah, Malaysia’. There is no 
specimen Nyhuus 2003 in UC but the specimen labelled as holotype is Nyhuus s.n. and 
‘2003’ is the year of collection as also noted for Hoya walliniana. Type citation has 
been amended accordingly. 
Hoya obscura Elmer ex C.M.Burton, Hoyan 8(1): 15 (1986). - Hoya obscura Elmer, 
Leafl. Philipp. Bot. 10: 3586 (1938), nom. inval. (missing Latin description). - TYPE: 
Philippines, Luzon, Sorsogon, Irosin, Mt. Bulusan, July 1906, Elmer, A.D.E. 16719 
(lectotype US [US00026729], designated here; isolectotypes BISH [BISH1000882], 
BM [BM000945396], BO, G, GH, K [K000911128], L [L0004338], L(U) 
[U1102639], NY [NY00318665], P [P00639850], S [S12-12728], UC [UC272655], 
US [US00026729]). Philippines, Luzon, Nueva Vizcaya, vicinity of Dupax, March- 
April 1912, McGregor, R.C., 11377 (epitype BM [BM001135048], designated here). 
Notes. No single holotype of Hoya obscura Elmer ex C.M.Burton was stated by Burton 
and a lectotype needs to be designated among the duplicates of the type collection 
Elmer 16719. All duplicates located and examined are sterile and a selection of an 
epitype is necessary for a correct application of the name. Specimen McGregor 11377, 
a fertile and well-preserved specimen is therefore selected as epitype of H. obscura. 
Hoya obtusifolia Wight, Contr. Bot. India 38 (1834); Rintz, Malayan Nat. J. 30: 520 
(1978); Jagtap & Singh, Fasc. FI. India 24: 113 (1999); Noltie, Bot. Robert Wight 170 
(2005). - TYPE: sin. loc. (Malaysia, Penang?), Wallich, Waif Asclep. 38 [= Wall. Cat. 
8167] (holotype K [K000895115]; isotypes E [E00179578], K [K001129115]). 
Hoya teysmanniana Miq., FI. Ned. Ind. 2: 522 (1857). - TYPE: Indonesia, Sumatra, 
Soengi Pagoe, s.d., Teijsmann, J.E., 1170HB (lectotype U [U0000686], designated 
here; possible isolectotype K [K000894744]). 
Notes. Duplicates of Wall. Asclep. 38[= Wall. Cat. 8167] have been found at E and K. 
The K duplicate is the only one bearing a Herbarium Robert Wight Proper (HRWP) 
label, it is annotated ‘38 Hoya obtusifolia RW’, and is therefore one of Wight’s 
specimens on which he based his descriptions. Linn Soc Mss SP1284 indicates that 
only 1 sheet of Wall. Asclep. 38 was given to Robert Wight for his personal working 
herbarium, therefore the K sheet can be considered a holotype. 
Hoya teysmanniana Miq. was described from Teijsmann material indicated as 
being from ‘Sumatra, bij Soengi Pagoe’. The U specimen [U0000686] is the only one 
found which matches this information and is therefore selected as lectotype. The K 
specimen [K000894744] was also collected by Teijsmann in Sumatra and bears a label 
in Miquel’s hand. However, it does not have a collection number or locality (Sumatra 
only) and may be considered as a possible isolectotype.
