British North Borneo, Rosab, near Kudat, Castro 972, Novem- 
ber 14, 19210. Om dry slopes, altitude about 50m. A species well 
characterized by its unusually large subsessile leaves and by its 
very large flowers. 
In this connection the species described by' nie from Amboina 
as Gordoma rumphw Merr. Inter. Herb. Amb. (1917) 368 is mani- 
festly identical with the form described by Miquel as Laplacea am-. 
boinensis. The synonymy should be as follows: 
Gordonia amboinensis (Miq.) comb. nov. 
Laplacea amboinensis Miq- Ann. Mus. Bot. Lugd. Bat. 4 (1868): 
114. 
Haemocharis ambowmensis Burkill in Jour. Str. Branch Roy. 
As. Soc. 76 (1917) 141, 158. 
Gordona rumphiu Merr. Interpret. Herb. Amb. (1917) 368. 
I agree with Burkul’s expressed opinion* that the Malayan 
species of Haemocharis (Laplacea) should be placed in Gordoma. 
In discussing this particular species Mr. Burkill treated it as. 
Haemocharis rather than Laplacea. I can find no reference to its. 
previous treetment under Haemocharis.
