Names and types of Bornean Hoya 
63 
ACKNOWLEDGEMENTS. This study is part of an on-going research project on the 
systematics of Asian Apocynaceae. Financial support was received from the National Parks 
Board (Singapore) which sponsored numerous herbarium study trips to Asian and European 
institutions. The curators of A, BISH, BM, BO, BRUN, CGE, E, FI, G, HITBC, HN, IBSC, 
K, KEP, KUN, L, OXF, P, SAN, SAR, SING, SNP, TO, UC, US, VN, WRSL and Z herbaria 
are thanked for allowing access and/or for allowing loans or high quality images of herbarium 
specimens. The librarians of the Singapore Botanic Gardens, Royal Botanic Gardens Kew 
and Royal Botanic Garden Edinburgh have helped to find often obscure references. Elisabeth 
Liljebjorn spent many hours scanning all the issues of the journals Fraterna and Hoyan as well 
as creating PDFs of numerous papers. Lastly Anthony Lamb and Anthea Phillips are thanked 
for their continuous support for my work on Bornean Hoya.
