Trees or shrubs, with yellow wood, evenly pinnate leaves, the leaflets ob- 

 cordate, the spinescent stipules persistent or deciduous, the showy yellow 

 minutely bracted flowers in loose axillary racemes. Calyx-tube very short, its 

 5 segments imbricated, somewhat unequal. Petals 5, oblong, spreading, some- 

 what unequal. Stamens 10, distinct ; filaments pilose at the base ; anthers all 

 alike. Ovary short-stipitate, 2-3-ovuled; style filiform; stigma terminal, small. 

 Pod flat, membranous, oblong or lanceolate, not dehiscent along the sutures, 

 but splitting through the middle of the valves. Seeds transverse, oblong; endo- 

 sperm none; cotyledons 2-lobed. [Greek, bloodwood.] Two known species, the 

 following typical. 



1. Haematoxylum campechianum L. Sp. PI. 384. 1753.

 ing branches, the trunk ridged, the bark smooth and light gray, the twigs 

 slender. Stipnlar spines 5-15 mm. long; leaves petioled, 5-10 cm. long; 

 petioles very short; leaflets 2-4 pairs, chartaceous, cuneate-obovate, 1-3 cm. 

 long, finely many -veined, usually rather deeply emarginate, shining above; 

 racemes several-many-flowered, short-peduncled, 2-5 cm. long; pedicels fili- 

 form, spreading, 4-6 mm. long; calyx 34 mm. long, its segments oblong-lanceo- 

 late, acute, unequal; petals obtuse, 4-6 mm. long; stamens about as long as the
