corolla, the middle lobe of the lower lip being orbicular, entire, 
and glabrous; and in its glabrous, not tawny-pubescent fruits. 
In H. Lam’s recent treatment of the Verbenaceae of the Ma- 
layan Archipelago certain reductions of proposed new species 
must be made: Vitex curranii H. Lam is identical with Vitex 
aherniana Merr.; Vitex merrillii H. Lam is identical with V. 
longifolia Merr., which in turn is a Teijsmanniodendron perhaps 
not distinct from T. bogoriense Koord.; and Vitex glandulosa H. 
Lam is identical with V. parviflora Juss., of which V. littoralis 
Decne. is a synonym.
