47. ERYTHRINA Linnaeus 



Trees, usually with prickly branches, the leaves 3-foliolate, the petio- 

 lules with prominent glands at their tips. Flowers large, red, in dense 

 racemes. Calyx oblique, spathe-like, finally splitting to the base, or cam- 

 panulate and 2-lipped. Petals very unequal, the standard longer than the 

 kefel and wings. Upper filament free nearly to the base, or more or less 

 connate with others. Ovary many-ovuled; style incurved. Pod linear, 

 swollen, contracted between the seeds or flattened at one end. (Greek 

 "red" in allusion to the large red flowers.)

1. E. indica Lam. Dap-dap (Tag., Vis.). 



A diciduous tree reaching a height of 15 m, the branches and branchlets 

 stout, armed with short, few to many, sharp prickles. Leaflets broadly 

 ovate, 8 to 18 cm long, somewhat acuminate, base broad or subrhomboid. 

 Racemes terminal, pubescent, dense, up to 25 cm long. Flowers large, 

 numerous. Calyx about 4 cm long, minutely 5-toothed at the tip, mouth 

 very oblique. Petals bright-red, thestandard 7 to 9 cm long, the wings 

 and keel subequal, shorter than the calyx. Pod 10 to 25 cm long, 1.5 to 2 

 cm in diameter, distinctly constricted between the seeds. (Fl. Filip. 

 pi. 217.) 



Common, fl. Jan.-Apr., quite or partly leafless at time of flowering; 

 throughout the Philippines, especially near the sea. India, through Malaya 

 to Polynesia. 



2. E. fusca Lour. (E. ovalifolia Roxb.). 



A tree reaching a height of 10 m, the trunk with large, conical protu- 

 berances, the branchlets and sometimes the petioles with small scattered 

 prickles. Leaflets oblong or elliptic-oblong, 8 to 15 cm long, acute or 

 obtuse, base acute or rounded. Racemes 10 to 20 cm. long. Calyx pubes- 

 cent, 2-lipped, about 1 cm long. Petals dull-purplish-red, the standard 

 about 4 cm long, rounded or emarginate, the keel about one-half as long, 

 the wings somewhat shorter than the keel. Pods subcylindric, 10 to 25 cm 

 long, about 1.5 mm wide, 6- to 11-seeded, apiculate. (Fl. Filip. pi. 326.) 



In open wet lands, fl. Jan.-Feb.; widely distributed in the Philippines. 

 India, through Malaya to Polynesia. 



3. E. subumbrans (Hassk.) Merr. Dap-dap (Tag.). 



A tree reaching a height of 15 m, unarmed or with- few prickles. 

 Leaflets ovate, acuminate, base rounded or subacute, 7 to 14 cm long. 

 Racemes pubescent, in the upper axils; about 10 cm long. Calyx pubescent, 

 about 8 mm long, 2-lipped. Petals red, the standard about 3 cm long, the 

 keel and wings subequal, less than one-half as long. Pod flat, indehiscent 

 and seedless in the lower one-half, bearing 1 to 3 seeds at the tip, 10 to 12 

 cm long, with a elongated slender stalk. (Fl. Filip. pi. SiS, E. lithosperma.) 



A single specimen in the old botanical garden fl. Oct.-Feb.; widely dis-
