The great need for adequate documentation of germplasm collections, including accurate geographic location, needs again to be stressed. We discuss 3 reported stations for teosinte (Zea spp.,
Toward Target 2 of the Global Strategy for Plant Conservation: An Expert Analysis of the Puerto Rican Flora to Validate New Streamlined Methods for Assessing Conservation Status1
Two systems that efficiently use available data to assess conservation status were tested against a provisional International Union for Conservation of Nature and Natural Resources (IUCN) Red List analysis to evaluate the native seed plant species of Puerto Rico and it was demonstrated that both systems efficiently identify species at risk.
Nickel hyperaccumulation in populations of Psychotria grandis (Rubiaceae) from serpentine and non-serpentine soils of Puerto Rico
