Discussion

  • Bactris martiana is diagnosed by its 46-60 pinnae per side, regularly arranged, spreading in the same plane, linear or linear-lanceolate, and 45-70 x 2-3 cm, pistillate flowers with a staminodial ring, and congested, irregularly and narrowly obovoid, purple black fruits 3.5- 5.5 x 2- 2.5 cm. Henderson (1995) recognized a broadly conceived B. concinna, with three varieties, of which this one was called Baetris concinna var. concinna. Here these are recognized at the specific level. This species is named for Carl von Martius, pre eminent student of palms. (Henderson, A.J., Bactris (Palmae) in Flora Neotropica Monographs 79. 2000)A

Use Record

  • Bactris martiana A.J.Hend.: The mesocarp, known locally as carne (meat) in the Pacaya-Samiria National Reserve, has an intriguing flavor because it is sweet, but with a hint of tartness. (Smith, N., R. Vásquez, and W. H. Wust, Amazon river fruits. Flavors for Conservation. 2007)
