Bonnetia duidae Kobuski & Steyermark, Jour. Arnold Arb. 29: 411. 1948.

Type. Shrub 4-5 ft tall, leaves in terminal rosette, coriaceous, deep rich olive green above, yellow or golden green below, petals deep rose; dry ridge top, summit Cerro Duida at 1700—1900 m alt, 1 Sep 1944, Territorio Amazonas, Venezuela, Julian A. Steyermark 58186 (holotype F, isotypes [fragments] NY).

Neogleasonia duidae is known only by the type collection which consists of the holotype and several packets of fragments. By virtue of similarity of leaf form and venation (noted by Kobuski & Steyermark in Kobuski, 1948), the species has been tentatively placed in Neogleasonia. Relationship to Bonnetia lanceifolia, as indicated by these authors, is not borne out in view of the fuller understanding of generic delimitation as is now possible. Neogleasonia duidae is the only element of the genus that has pubescent leaves and inflorescence.
