nerved, these often obscured, granular punctate and green 

 above, but not pubescent, except sometimes along the margin 

 or at the junction with the petiole, the under side red, pubes- 

 cent, with short curved hairs, or occasionally merely granular; 

 spikes very long and slender, commonly as long or longer than 

 the rest of the plant.

Peperomia 



Another species from Kauai, which cannot be satisfactorily 

 placed, was first collected at about 3000 feet elevation, on the 

 ridge west of the Hanapepe river, where it was found growing 

 at the base of trees. The plants from this place are small, 

 less than six inches high. The stems are usually simple, but 

 sometimes branched above, slightly channeled, pubescent 

 throughout. The leaves are on short petioles, opposite, or in 

 threes, about an inch in length, thin, lanceolate, with tapering 

 base, three-nerved, or the upper appearing as if one nerved, 

 hairy on both faces. The spikes are terminal, single, slender, 

 the rachis strongly angled, glabrous, on sparingly pubescent 

 pedicels. Above Waimea, Kauai, at 4000 feet elevation, larger 

 specimens were collected, which also appear to belong here.
