Comments:
- A main diversification area of Puya extends in the Paramo and high Andean grasslands from Colombia to NW Argentina, including species adapted to temperate to cold tropical conditions (Smith and Downs 1974) A second, less explored diversification region involves the subtropical, humid to semiarid forests and valleys of Bolivia and NW Argentina (Vasquez and Ibisch 2004), which has recently added several new species (e.g. Vasquez and Ibisch 2004, Ibisch and Gross 1998) to the already long list of Bolivian Puya species (Kromer, 1999). The purpose of the present paper is to describe a new species found at the border between Bolivia and Argentina belonging to the latter diversification area.
Distribution and habitat: The new species grows on rocky slopes of the Bermejo River gorge that builds the Bolivia-Argentina frontier, in the Tucumano-Bolivian forest, between 500 and 1,000 m elevation in an area with annual rainfall of 1,500-2,000 mm concentrated in the November-April period. —See J.
