 but hard. (Cont., M'. I.) 



4. DELONIX Eaf. Unarmed trees with smooth bark. Leaflets relatively 

 small and numerous: blades narrow. Sepals much shorter than the petals. 

 Blades of the petals mainly flabellate, all long-clawed. Pod elongate-linear, 

 flat, the valves woody. 



1. D. regia (Boj.) Eaf. Tree or shrub with a wide top: larger leaves with 

 20-50 pinnae; leaflets numerous, the blades linear-oblong, 4-10 mm. long: 

 sepals 22-26 mm. long: petals 5-7 cm. long, red or orange; blades broader 

 than long, crisped : pods linear, commonly 3-5 dm. long. — Spr. 



The ROYAL-poiNCiANA grows in hammocks and pinelands in southern peninsular 

 Florida and the Keys. It is native of Madagascar. The whitish or yellowish wood 

 is close-grained and heavy, but soft and weak. Also known as Flame-tree. (^V.I.) 



5. POINCIANA [Tourn.] L. Erect mostly unarmed shrubs or trees. 

 Leaflets usually few and relatively large: blades rather broad. Sepals much 

 shorter than the petals. Blades of the short-clawed petals not flabellate. 

 Pod flat, narrow, the valves leathery. Seeds flattened. 



1. P. pulcherrima L. Small tree or shrub: leaflets numerous; blades oblong 

 to cuneate, 15-25 mm. long: sepals 1.5-16 mm. long: corolla mainly red; 

 standard 25-27 mm. long: filaments 40-45 mm. long: pods 9-13 cm. long. —

The Barbados-flower, a native of the West Indies, grows in hammocks and 

 pinelands in southern peninsular Florida and the Keys. The wood has not yet been 

 studied. (W. I.) 



6. TAMAEINDUS [Tourn.] L. Unarmed trees. Leaves relatively small: 

 leaflets numerous: blades rather narrow. Sepals 4. Petals 5, but 2 of them 

 rudimentary. Stamens 3, the filaments united to about the middle, alternating 

 with 3 minute staminodia. Ovary elongate. Pod indehiscent, succulent within. 

 1. T. indica L. Tree with spreading branches: leaflets 18-36, 1-2 cm. long,
