Leaf with (a few) special glands on the lamina

The following is a list of native or naturalised species which, at least some of the time, possess this spot-character.

This spot character covers cases where a usually small number of distinctive glands are borne on the lamina. An example is the pair of glands which occur near the leaf base in Macaranga mellifera (see image).

It is not intended to include cases where there are pellucid gland dots throughout the lamina (spot charcter 719) or cases where the lamina is covered with glands beneath (spot character 755).
