Abstract

Piper alwynii M. A. Jaram. (Piperaceae), a new species occurring in sandstone outcrops of the Cordillera del Cóndor at the border of Ecuador and Peru, is here described and illustrated. Morphologically it shows similarities to species in the Radula clade. Piper alwynii is similar to P. purdiei C. DC. but differs in having leaves pinnately nerved within the lower two thirds of the midvein, nerves pubescent on the abaxial surface, villous peduncles, and spikes 2–2.7 cm long. An identification key for 32 northern South American Piper L. species with small (≤ 10 cm) leaves is presented.

期刊介绍： Novon is a quarterly, peer-reviewed botanical journal whose purpose is to publish articles establishing new nomenclature, including new taxa and new names, for vascular plants and bryophytes. Short papers typifying existing names may also be accepted. Lengthy revisions that primarily describe and discuss known species, while publishing nova incidentally, are not appropriate for Novon. Articles may be written in English or Spanish.
