1. The present notes on Teijsmanniodendron are based on a study of the spec- imens from Herbarium Bogoriense and the Herbarium of the Singapore Botanic Garden. <br /> 2. The taxonomic value of the principal characters and their variation are discussed. Each of the species recognized is annotated.<br /> 3. A delimitation and subdivision of the genus in two sections,  Plurifoliolatae Kosterm.  and 'Unifoliolatae Kosterm  is proposed. <br />4. A key to the 12 species and 1 variety distinguished, is included. 5. One new species is provisionally described (but not named), and one new variety, Teijsmanniodendron pteropodum var. auriculatum Kosterm, is published.<br /> 6. The following new combinations are made: Teijsmanniodendron coriaceum B. Clarke) Kosterm,, T. hollrungii (Warb.) Kosterm. T. holophyllum (Bak.) Kos- term, T.novoguineense (Kan. &amp; Hatus.) Kosterm., T. sarawakanum (H. H. W. Pears.) Kosterm., T. smilacifolium (H. H. W. Pears.) Kosterm., and T. subspieatum (Hallier f.) Kosterm. <br />7. The genus Xerocarpa H. 3. Lam (non Spach) is rejected; its only species, X. avicenniaefoliola H. J. Lam, is referred to Teijsmanniodendron ahernianum (Merr.) Bakh. In addition, the following reductions are made: Teijsmanniodendron mono- phyllum Kurata = T. hollrungii (Warb.) Kosterm.; Vitex bankae H. J. Lam = T. ahernianum (Merr.) Bakh., V. bogoriensis H. J. Lam = T. ahernianum (Merr.) Bakh.; V. koordersii H. J. Lam t= T. pteropodum (Miq.) Bakh.; V. tetragona Hallier f. = T. sarawakanum (H. H. W. Pears.) Kosterm.; V. venosa H. J. Lam = T. coriaceum (C. B. Clarke) Kosterm. Possible identity of T. longifolium (Merr.) Merr. and T. bogoriense is suggested: the identity of T. simplicifolium Merr. and T. smilacifolium (H. H-, W. Pears.) Kosterm. is indicated as probable.<br /> 8. Vitex subspicata Hallier f. and V. holophylla Bak. included by Lam in vitex hollrungii Warb. are reinstated as distinct species of Teijsmanniodendron.
