Litseasarawacensis Gamble, Bull. Misc. Inform. Kew365 (1910). -TYPE: Singapore, 
Reservoir Woods, July 1893, H.N. Ridley 4S7 7 (lectotype K [K000797140], designated 
here; isolectotypes B, SING [SING 0011250]). 
In the original description of Litsea sarawacensis Gamble (Gamble, 1910: 365-366), 
several morphological very similar gatherings were cited: Ridley 4817; Beccari 905, 
1475, 1708, 1796; Havilland 3077 and 3646. The K sheet of the gathering from 
Singapore, Ridley 4817, is designated here as the lectotype. 
Litsea singaporensis Gamble, Bull. Misc. Inform. Kew 358 (1910). - TYPE: 
Singapore, Garden Jungle, Nov. 1892, H.N. Ridley 4135 (lectotype K, designated here; 
isolectotypes BM, SING [SING0000630]). 
Numerous gatherings were mentioned in the original description of Litsea singaporensis 
by Gamble (1910: 358): H.N. Ridley 2118, 3372, 3894, 4135, 4826, 5065, 5736, 5738, 
9075 and R. W. Hullett 5738. I was unable to locate two of these (H.N. Ridley 2118 and 
R.W. Hullett 5738). As Gamble was working at Kew at the time he wrote this article, 
the K specimen of H.N. Ridley 4135 is designated here as the lectotype. 
Litsea umbellata (Lour.) Merr., Philipp. J. Sci. 14: 242 (1919). -Hexanthus umbellatus 
Lour., FI. Coc hin ch 196 (1790). - TYPE: Cochinchina, Loureiro s.n. (lectotype BM 
[BM000951060], designated here; isolectotype BM [BM000951061]). 
Two sheets of type material of Hexanthus umbellatus are extant at BM. One has flowers, 
leaves and twigs [BM000951060] and the other has several loose leaves, a twig and 
some flowers [BM000951061]. The first sheet is designated here as the lectotype.
