DOUBTFUL SPECIES. 



* H. ANOMALA, Don Prodr. 211 ; DC. Prodr. iv. 15 ; leaves sinuate-crenate nearly 

 glabrous ovate rounded at the base 4 in., radiate flowers 0. Nipal. Of this no spe- 

 cimen exists at Kew. Perhaps it is but a synonym of H. altissima. H. f. & T. (in 

 Journ. Linn. Soc. ii. p. 76) reduce it to Dichroa, but that has not ovate leaves rounded 

 at the base.

 Leaves coriaceous, petioled, obovate-oblong, entire, persistent. Panicles terminal.

 vate, falling off in a cap. Stamens 8 or 10, subepigynous. Ovary inferior, 

 4-6-celled; style thick, surmounted by a thicker truncate pyramid the 4-6 

 angles of which are stigmatic ; ovules numerous, elongate, pendulous. Seeds
