 to warrant its definite identification. It may be an Ixora.

Earlier collections were confused with Ixora cumingiana Vid. and I. 

 macrophylla Bartl., and later ones with I. longistipula Merr. It is allied 

 to I. macrophylla Bartl. but has narrower leaves and usually terminal 

 inflorescences which are always subtended by reduced leaves. The in- 

 florescences are puberulent, even in the type, not glabrous as described. 

 Ixora longistipula Merr., an allied form, has strictly glabrous inflores- 

 cences and flowers.
