Conservation
With no confirmed records for over 95 years and no details about the plant’s frequency or its habitat, this species can only be categorised as Data Deficient (DD) within IUCN guidelines. It is possible that it is extinct, but the author’s experience of other old records from the Andes suggests this is unlikely to be the case and that this species may be refound after careful, focused search.
Distribution
Endemic to Peru.
Ecology
Nothing is known of its habitat, but it presumably grew in forest.
Morphology Reproductive morphology Inflorescences
Inflorescence formed of a well-branched rather lax thyrse 25 × 8 cm, corolla and capsule densely hirsute with short spreading hairs; calyx lobes filiform, c. 6 mm long, but accrescent to 10 mm; corolla tube c. 9 mm long, the lobes of lower lip free c. 3 mm long
