Type
Brazil. Bahia, Igreja Velha. Blanchet 3456 (lectotype G!, designated by Sleumer 1954 [photo. F!, GH! neg. 7448]; isolectotypes B!, BM!, NY!).
Morphology General Habit
Shrub 3 - 4 m tall
Morphology Leaves Leaflets
This species is characterised by possessing leaflets very similar to those of E. incana (sparsely rufous-pubescent beneath and glabrescent above with serrate to denticulate margins), but with revolute margins that cause parts of the lamina to fold over in herbarium material
Morphology Reproductive morphology Inflorescences
Young inflorescence ferruginous, peduncle and pedicels greenish-red
Morphology Reproductive morphology Flowers Tepal
Tepals cream within, ferruginous oin the outside
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens reddish to brown
Morphology Reproductive morphology Flowers Gynoecium Style
Style green
Morphology Reproductive morphology Flowers Gynoecium Ovary
Fused hypogynous glands, and a rufous velutinous ovary.
Distribution
Only known from the state of Bahia.
Phenology
Flowering in January and July.
Note
Only a small number of specimens are known of this species and are insufficient to determine whether E. bahiensis should be considered a subspecies of E. incana. The distribution of both species are separated by almost 2000 km, but certain facets of E. bahiensis, especially the leaves, are reminiscent of E. incana. Both species share a densely hairy ovary, fused hypogynous nectaries and a similar leaf and inflorescence indumentum. The principle differences are the long inflorescences, frequently surpassing the leaf rhachis in length, the revolute leaflet margins, and the velutinous ovary indumentum of E. bahiensis.
