Amsh. var. coriaceaAmsh. - Leguminosae - Papilionoideae, located at Ducke Forest Reserve, including flowering, fruiting and leaf change. The period of time, duration and frequency of reproductive phases are reported, as well as the type of leaf change. The species showed the flowering phase in the dry season. The fruiting phase was observed in the middle of dry season and at the beginning of wet season. The duration of the flowering and fruiting was about 6 and 7 months. In reference to the occurrence of flowering and fruiting both were annual to irregular, although at the individual level the behavior was irregular. Considering the leaf changes the species showed a semi-deciduous pattern during the flowering, in the dry season.
