 jointed to the nodes. Leaves mostly opposite, stipulate, pinnate, or 2-3- 

 foliolate, the leaflets entire. Stipules persistent. Flowers perfect, axil- 

 lary, peduncled. Sepals usually 5, distinct, or united by their bases. 

 Petals the same number as the sepals, or none. Stamens as many as the 

 petals, or 2-3 times as many, inserted on the base of the receptacle, the 

 alternate ones sometimes longer; anthers versatile, longitudinally dehis- 

 cent; filaments usually with a small scale at the base or near the middle. 

 Ovary 4-12-celled; style terminal; stigma usually simple; ovules 1-nu- 

 merous in each cavity, pendulous or ascending. Fruit various. About 20 

 genera and 160 species, widely distributed in warm and tropical regions.

 evenly pinnate leaves of few broad leaflets, I'-IA' long, and large clusters of 

 blue flowers, is occasional in gardens, A tree at Pembroke Hall Avas about 30° 

 high in 1913, 



Zygophyllum foetidum Schrad. & Wendl., Bean Caper, South African, a

 celled, sometimes crested. Ovules solitary in each cavity, nearly orthotro- 

 pous. Fruit of 2-3 pulpy or hard dilipes, or sometimes capsular or nut- 

 like. Seeds pendulous; endosperm wanting; embryo with thick often un- 

 equal cotyledons. About 60 genera and 700 species, in warm and tropical 

 regions. Most of the species of Malpighia bear stinging hairs. 



Malpighia punicifolia L., French Cherry, West Indian Cherry, of 

 tropical America, a shrub, or small tree up to 15° high, with rather thin, ob- 

 long to obovate, obtuse, short-petioled leaves l'-3' long, axillary cymes of 

 small pink flowers, followed by scarlet or red drupes 5"-8" in diameter, 

 pleasantly acid and edible, is frequently grown in gardens. 



Malpighia setosa Spreng., recorded, with doubt, by Lefroy. has similar
