Hymenolobium spp. of the family Leguminosae (subfamily Papilionoideae), the legume or pea family
I was told by Paul van Rijckevorsel that in Brazil the name "angelim" can be applied to several coarse woods in the family Leguminosae and that usually angelim pedra will refer to Hymenolobium petraeum, however, there are at least 2 other species in the genera Hymenolobium plus 3 in the genus Andira, and a couple more random species from other genera, all of which use the name angelim pedra and I have no great confidence as to which of them are displayed on this page unless explicitly stated.
