Selbyana 23(1): 46-56. 2002. MISCELLANEOUS NEW TAXA OF BROMELIACEAE (XVII) HARRY E. LUTHER Mulford B. Foster Bromeliad Identification Center, Marie Selby Botanical Gardens, 811 South Palm Avenue, Sarasota, FL 34236 USA. E-mail: [email protected] ABSTRACT.' Seven new taxa of Bromeliaceae are described: Pepinia neeana from Brazil, Puyajoergensenii from Ecuador, Greigia leymebambana, Pepinia peruana, Pitcairnia arenaria, Pitcairnia campos ii, and Puya pseudoeryngioides from Peru. Miscellaneous new taxa of Bromeliaceae (XVI) appeared in Brittonia 54(4), 2002.
