npisoniaA genus of trees and shrubs, of the order Nyctagineæ, type of the tribe Pisonieæ, characterized by the terminal stigma and six to ten exserted stamens. There are about 60 species, mainly of tropical America. They bear opposite or scattered oblong-ovate or lanceolate leaves, small diœcious rose, yellow, or greenish funnel-shaped flowers in panicled cymes, and a rigid or stony, rarely fleshy, elongated fruit (an anthocarp), often with rough and glutinous angles. Several species are trees cultivated for ornament. P. Brunoniana is the New Zealand para-para tree, a hardy evergreen; others are greenhouse shrubs with green flowers, as the flngrigo or cockspur, a rambling prickly bush of the West Indies with glutinous bur-like fruit, forming thickets. See beefwood, 2, corkwood, and loblolly-tree.
