Venezuela. Monagas: Caicara, 15 May 1952, F. D. Smith 226 (holotype, US [US-2121468]!; isotype, US!, US photo at MO [MO-067514]!, [MO-067514]!)

Habitat and distribution.

Tanaecium apiculatum is known only from the type location, Caicara, Venezuela.

Phenology.

Flowering: May; fruiting (immature): May.

Notes.

This species shares wide infundibular corollas with T. crucigerum , T. cyrtanthum , T. duckei , T. exitiosum , T. kuhlmannii , and T. jaroba , but can be differentiated from these taxa by the leaflets with apiculate apices and cartilaginous margins, and tubular calyces with stellate simple trichomes (Tab. 1 View Table 1 ). Out of these species, Tanaecium crucigerum and T. jaroba are the only ones that also occur in Venezuela. These species can be differentiated from T. apiculatum by the abaxial surface whitish-tomentose in T. crucigerum and abaxial surface glabrous or pubescent in T. jaroba (vs. abaxial surface glabrous in T. apiculatum ).
