Description
|
Shrub or tree to 7 m high, the branches glabrous or pubescent on young portions. Leaves imparipinnate, with 1-6 pairs of opposite leaflets, the rachis 3-14 cm long and often winged, the leaflets sessile or with petiolules to 1 mm long; lamina of leaflets obovate or elliptic to oblong or oblong-lanceolate, apically acute to rounded or rarely emarginate, occasionally mucronulate at the apex, basally cuneate, 1.5-7.5 cm long, 0.7-3.2 cm broad, having a length/width ratio of 1.3/1 to 3/1, entire or serrate, glabrous to conspicuously pilose, darker and often lustrous above, thickly membranous or subcoriaceous, the secondaries apparent, the reticula- tion obscure or subobscure. Inftorescences paniculate to subracemose, axillary, 1-11.5 cm long, conspicuously hirsute to glabrate. Flowers male or female (a pistillode present in male flowers, staminodes present in female flowers), the pedicels 0.5-3 mm long; calyx-segments 5, deltoid, ca 0.75 mm long, often ciliate marginally; petals 5, ascending, oblong to ovate, apically rounded or subtruncate, white, 1.2-2.5 mm long, often curled outward at the tip; stamens 10, the anthers ovate and 0.5-0.8 mm long in male flowers, the filaments compressed-subulate; disc 10-crenulate; ovary subglobose, ca 1 mm long, the ovule subapical, the style apparently single (the 3 styles confluent), 0.2-0.3 mm long, the stigmas 3, flattended, capitate. Drupes red, 4-6.5 mm long and broad.

Distribution

A native of Brazil (and probably Paraguay), S. terebinthifolius is cultivated in Central America (possibly naturalized in the Canal Zone), Florida, California and in various parts of the Old World.

Note
|
The four Brazilian varieties of S. terebinthifolius recognized by Barkley are based on stem and leaf pubescence, leaflet number and angle of the leaflet apex. Brief examination of Brazilian specimens deposited in MO indicated that these taxa may represent nothing more than different points on a continuum of inter- grading infraspecific variation in leaf and pubescence characters so often encoun- tered in plant species. However, the authors do not assume the competence in the genus required to definitively evaluate the status of these varieties and for this reason they have not been placed in the synonymy of S. terebinthifolius.
