Discussion:
Tabebuia insignis is often locally common in the poorly drained swampy areas where it mostly occurs, and sometimes forms nearly pure stands. It is distinguished by the combination of white flowers with leaves and calyx completely glabrous except for lepidote scales. This species differs most strikingly from T. fluviatilis, the only sympatric species with palmately compound glabrous leaves and white flowers, in having winged wind-dispersed seeds. As here interpreted, T. insignis is vegetatively very polymorphic in leaf texture and number of leaflets. I have accorded varietal recognition to the unifoliolate and simple-leaved entities but have not attempted to recognize the differences in leaflet number, shape, and texture that characterize T. dura, T. roraimae, and other unnamed Guiana shield variants.
