Navia grafii Steyermark & Holst[as Navia grafii Steyerm. & B. Holst]

Diagnose: —A Navia phelpsii foliis adultis tantum prope basin serrulata, inflorescentia haud digitata, bracteis paullo minute serrulata, bracteis exterioribus brevioribus 3-4.2 cm longis 0.9-1.5 cm latis, foliis brevioribus 18-23 cm longis 1.9-2 cm latis minus attenuatis, sepalis lineari-lanceolatis acuminatis 17-19 mm longis infra medium 3 mm latis recedit.

Observations: —This species is apparently variable as to amount of indument, spininess of leaves and floral bract margins, and leaf texture. Navia trichodonta is not clearly distinct from N. phelpsiae, and the two should perhaps be combined.
