The tribe Gardenieae in the restricted delimitation proposed by Bremekamp and Verdcourt is wood anatomically homogeneous. The genera of the Ixoreae studied by me also agree with each other in wood structure. Within the tribe Mussaendeae in the delimitation accepted by Schumann the wood anatomy shows much variation. The tribe becomes more homogeneous, if some of the genera included in this tribe by Schumann are removed. The systematic position of some genera, which in the literature are said to be related to Gardenieae, Ixoreae or Mussaendeae, is discussed in the light of similarities and differences in the wood anatomy.
