This species is distinctive in its elliptic leaves and long infructescences sometimes with short lateral branches in the lower part. The reticulate venation of the leaves and the domatia each with a distinct aperture are very much as in T. glabra and T. celebica, to which T. glandulosa appears closely allied.
