Acrostemon}. ERICACEZ (Brown). 351 
Species 9, endemic. 
This genus has been combined with Grisebachia, but is readily distinguished 
by its anthers alone, which are exserted, basifixed, deciduous, much longer than 
broad, and their cells are connate below; whilst in Grisebachia the anthers 
rarely exceed the corolla-lobes, are scarcely longer than broad, and their cells are 
quite disconnected from each other and dorsifixed near the base or taper into a 
slender attachment to the filament.
