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.
