Discussion:In the Costa Rican collection the stem shows two lines of pubescence between the glabrous areas. The following Central American collections have a densely tomentose exterior on the stipular sheaths, but the upper internodes of the stems are pubescent in two lines between the glabrous areas, and tend towards the f pubescens of var andina: Costa Rica (Skutch 3039; L. Williams, Molina, T. P. Williams & Gibson 28591; L. Williams, Jiménez & T. P. Williams 24319); Panama (R. S. Williams 835).
