A shrub or small tree growing on the strand with gray velvety branches, yellow 
flowers, and necklace-like pods with joints separated by narrow necks. Leaves odd- 
pinnate with 7 or 8 pairs of leaflets, which are shortly stalked and often alternate, 
4cm. long, broadly oval, obtuse and rounded at both ends, pubescent; flowers rather 
large, pedicels as long as the calyx, jointed near the top, rather closely arranged in 
stout, erect, stalked racemes about 15 cm. long; needle-like bracts deciduous; calyx 
somewhat inflated, velvety, segments very small; pod covered with velvety down, 
5 to 15 em. long, long-stalked; seeds nearly globular, pale brown, 9.5 mm. in diameter. 
This plant is not common in Guam. It grows sparingly on the windward side of 
the island on the sandy beach between Pago and Talofofo. It is widely spread on 
tropical shores. The natives had no vernacular name for it and said that it had 
recently appeared on the island. 
All parts of the plant, but especially the bark of the root and the seeds, are bitter 
and yield a poisonous alkaloid called sophorine. In the Malay Archipelago the pul- 
verized seeds are used as a specific for dysentery and cholera and as an antidote after 
having eaten poisonous marine animals. Padre Blanco says that the seeds are purg- 
ing.¢ Two of them are almost too drastic for a dose in tertian fever. They area 
common remedy among the natives of the Philippines for disorders of the stomach 
and were at one time a popular remedy for cholera morbus.
