Description

Trees, 3-20 m high; trunks usually armed with numerous vertically flattened prickles, the branchlets hispidulous, becoming glabrate, usually armed with small sharp prickles. Leaves odd- or rarely even-pinnate, usually conspicuously yel- lowish pubescent, especially below, 25-68 cm long; petiole and rachis sometimes armed with scattered yellowish prickles, more or less canaliculate above, his- pidulous and strigillose; leaflets 15-27, subopposite, elliptic to lanceolate or rarely ovate or obovate, acute and long acuminate apically, inequilateral and more or less acute basally, the margins crenulate and revolute, the blade pellucid punctate throughout, subcoriaceous, strigose above, the midvein hispidulous, paler and hispidulous beneath, especially on the veins, rarely with a few yellowish prickles on the midvein beneath, 3.0-13.5 cm long, 18-57 mm wide, the laterals more or less subsessile, the terminals petiolulate. Staminate panicles axillary and subterminal, congested, to 7 cm long, the branches hispidulous to villose. Stami- nate flowers yellow, the pedicels less than 1 mm long; calyx 5-lobed, less than 1 mm high, the lobes rounded, pubescent; petals 5, elliptic, 1.5-2.0 mm long; stamens 5, exserted, ca. 3 mm long; ovary 1-4-lobed, rudimentary, the styles 1-4. Carpellate panicles axillary, few- to many-branched, 3.5-16.0 cm long, the branches hispidulous to villose to almost glabrate, several often clustered together subapically on a branch to form a compact globose mass. Carpellate flowers with the pedicels less than 1 mm long; calyx 5-lobed, less than 1 mm high; lobes triangular, acute, pubescent; carpels 5, free. Follicles 1-4(-5), globose, brown, roughened with black or brownish punctations, glabrous, ca. 3 mm in diameter; seeds globose, dark brown to black, lustrous, minutely pitted, 2.5 mm in diameter.

known to flower in April and to fruit in March through October and in December. Zanthoxylum setulosum, the most widespread and common species of its genus on the Isthmus, has not been collected in the western third of Panama. It occurs in monsoon forest, mainly on the Pacific side of the Continental Divide. Leaves on young specimens are extremely prickly, more crenate, often less pubescent, and have more pellucid punctations than those of mature individuals. The stems of Erlanson 285 were noted as "hollow and filled with ants." Johnston (1949) has pertinent comments on the morphology of this species, and on its ability to spread into disturbed habitats. It is known as prickle yellow (Bartlett & Lasser 16550) in English, and as acabu, alcabu, or arcabu in Spanish, common names also applied to Z. panamense and other species.
