Card. Bull. Singapore 69(2) 2017 
The revisions of Lauraceae from Singapore are based on herbarium collections 
made in Singapore and now housed at the Natural History Museum, London (BM), the 
Royal Botanic Gardens, Kew (K and K-W), the Forest Research Institute of Malaysia 
(KEP) and the Singapore Botanic Gardens (SING). Type material not available at 
those institutions was studied online via JSTOR (https://plants.jstor.org/plants) and 
accessed in July 2017. In addition to the new records for Litsea, twenty-two names 
from all of the genera revised need to be lectotypified. Barcode information is given 
for all specimens where available.
