Distribution and habitat. – Tannodia cordifolia occurs in Madagascar and in the Comoro Islands ( Mayotte). In Madagascar, it occurs in the North around the Marojejy massif, Daraina and Ankarana, and also in the Southwest around the Analavelona massif. This species is present in dry and subhumid tropical forest.

Observations. – The type specimen of Amyrea maprouneifolia bears only fruit, and thus has lost the petals that serve to most easily distinguish Tannodia from Amyrea . However, the specimen’s tripliveined leaves and slightly verrucose, densely pubescent fruit would be unique in Amyrea but are typical of nearly all species of Tannodia . The 5 calyx lobes persisting beneath the fruit and the broadly obtuse leaf base mark the specimen as a small-leafed example of T. cordifolia .

On one fruit of the isotype of T. grandiflora var. myrtifolia at MO, parts of the 5 calyx lobes diagnostic (within Madagascan Tannodia ) of T. cordifolia can be discerned, pubescent and ciliate as in typical specimens, whereas T. grandiflora was described as having two glabrous sepals. All other morphological features of Service Forestier 23353 also accord with T. cordifolia Baill.
