P. san-joseanum C. DC. Shrub or small tree, usually ca 2 (3) m tall, +/- glabrous; branches often black when dry. Petioles to 6 cm long, vaginate-winged to blade; blades thin, round-ovate, sharply acuminate, usually cordate at base, 8-20 cm long, glabrous except at margin, drying with pellucid dots, the veins 9-13, palmate. Spikes usually 10-16 cm. long, 2-4 mm thick in fruit; peduncles ca 1 cm long; bracts rounded, densely ciliate with long white trichomes (+/- contiguous in spiral arrangements). Fruits obpyramidal, smooth, depressed-truncate at apex; stigmas 3, linear, deciduous. Croat 4582, 6908. Occasional, in clearings. Showing little seasonal flowering behavior, which is no doubt beneficial to its weedy, invading nature. Most flowering commences sometime after the first rains (usually in July) and continues into the earliest part of the dry season, occasionally to the end of the dry season. The fruits develop quickly, most maturing in the late rainy and early dry seasons. Cut parts are strongly and pleasantly aromatic.
