Discussion
lb. Tabebuia insignis var pacimonensis Sandwith, Mem. N. Y. Bot. Gard. 9: 365. 1957. Type. Venezuela, Amazonas, Rio Pacimoni, Bassett Maguire et al 36671 (NY). Shrub or small tree. Leaves simple, oblanceolate, obtusely cuspidateacuminate, cuneate-attenuate at base, 8-13 cm long, 3-4.2 cm wide, entire, rigidcoriaceous with revolute margins, the lateral nerves flat and obscure on the almost veinless lower surface, inconspicuously lepidote punctate above and below; petiole 1-1.5 cm long. Inflorescence and flowers as in T. insignis var insignis. Capsule unknown. This distinctive-looking plant, known only from the type, could prove a distinct species. But, as Sandwith noted in describing it, to treat it as more than a variety of T. insignis would be most imprudent without additional material. A simpleleaved collection of T. insignis from Vaupes, Colombia is somewhat intermediate between var pacimonensis and var monophylla and supports the former's retention under T. insignis.
