Frequent in the forest. Seasonal behavior uncertain. Flowers at least from December to July, especially from March to June. The fruits probably mature mostly from April to September, especially in the rainy season. A variable species, it has been identified by C. E. Smith under three other names as well, including G. guidonia (L.) Sleumer, G. kunthiana Adr. Juss., and G. tonduzii C. DC. It can be reported with certainty that G. tonduzii does not occur on BCI and furthermore that there is but a single species in this complex thus far collected on the island. The pubescence of the ovary, used in distinguishing G. glabra and G. guidonia, is at best a poor character.
