Trees. Leaves alternate, with stipules; blades unequally pinnately compound, the leaflets 

 several, alternate, large, the blades broad, entire. Paniclesterminal, large, with spreading 

 branches, many-flowered, the bracts minute, the pedicels short, spreading. Flowers rela- 

 tively small, approximate. Sepals 5, rather broad, imbricate. Petals 5, rather narrow, longer 

 than the sepals, yellow. Stamens 10 ; filaments filiform ; anthers short. Ovary 2-lobed, the 

 carpels united only by the stipes, rounded ; styles slender, distinct, basal ; stigmas capitate. 

 Ovules 2, or said to be sometimes 1, in each carpel. Drupes short, with a thin exocarp and 

 a bony stone. 



Type species, Recchia mexicana Moc. & Sesse. 

 Sepals oblong or nearly so ; petals linear-spatulate ; drupes obovoid. 1. R. bracteata. 



Sepals ovate or suborbicular ; petals oblong ; drupes oval. 2. R. mexicana. 



1. Recchia bracteata (Planch.) Small. 



Rigiostachys bracteata Planch. Lond. Jour. Bot. 6 : 30. 1847. 



A tree with obscurely puberulent twigs. Leaves 1 dm. long or more or sometimes 

 shorter, the rachis narrowly winged, the leaflets mostly 7-11, the blades ovate to oblong or 

 rarely obovate, 1-4 cm. long, obtuse or rounded at the apex, glabrous or sparingly pubes- 

 cent beneath, bright-green above, yellowish-green beneath, short-petioluled ; panicle- 

 branches spreading, like the pedicels obscurely puberulent ; bracts minute, deltoid to 

 deltoid-reniform ; sepals oblong or nearly so, 3.5-4.5 mm. long, ciliolate ; petals linear- 

 spatulate, 13-15 mm. long, not toothed at the apex ; drupes obovoid, fully 1 cm. long. 



Type locality: Mountains of Oaxaca, near the Pacific Ocean. 

 Distribution : Guerrero and Oaxaca. 



2. Recchia mexicana Moc. & Sesse ; DC. Syst. 1 : 411. 1818. 



A tree with decidedly puberulent twigs. Leaves about 1 dm. long or more, the rachis 

 very narrowly winged, the leaflets mostly 5-9, the blades ovate, oval, or oblong-ovate, 2-6 

 cm. long, commonly slightly acuminate, but obtuse, minutely pubescent, especially beneath, 

 deep-green above, paler beneath, short-petioluled ; panicle-branches and pedicels puberu- 

 lent ; bracts minute, nearly reniform ; sepals ovate to suborbicular, 3-4.5 mm. long, cilio- 

 late ; petals said to be oblong, longer than the sepals, subdenticulate at the apex ; drupe 

 oval, about 1.5 cm. long. 



Type locality : Mexico. 



Distribution : Western middle Mexico. 



11. PICRAMNIA Sw. Prodr. 27. 1788. 

 Trees or shrubs, usually with slender curving branches. Leaves alternate, persistent ; 

 blades unequally pinnate, the leaflets few, opposite or alternate, entire, thick or thin- 

 leathery, relatively broad and large, petioluled. Flowers very small, dioecious, in spread- 

 ing or drooping spike-like or raceme-like panicles. Sepals 3-5, narrow, at least, relatively 

 so, slightly united. Petals 3-5, broad or narrow, sometimes with an incurved tip, some- 

 what longer than the calyx, or wanting. Stamens 3-5, reduced to narrow or minute stami- 

 nodia in the pistillate flowers ; filaments slender, unappendaged ; anthers broad. Ovary 

 2- or 3-celled, sessile, the carpel-bodies united. Styles wanting. Stigmas 2 or 3, spreading. 

 Ovules 2 in each ovary-cavity, pendulous. Berries globose, or slightly elongate, with rather 

 juicy pulp. 



Type species, Picrantnia Antidesma Sw. 

 Sepals, petals, and stamens 3 or 4 ; panicle-rachis not branched, except occasionally near the base. 

 Sepals and petals 3. 1- P- Antidesma. 



Sepals and petals 4 ; or petals wanting. 

 Petals present ; panicles elongate. 



Berries glabrous ; leaflets becoming glabrous. 2. P. quale/ nana. 



Berries pubescent ; leaflets permanently pubescent beneath. 3. P. tetramera. 



Petals wanting ; panicles short. 4. P. brachybolryosa. 



Sepals, petals, and stamens 5 ; panicle-rachis simple or branched.
