This beautiful evergreen shrub with glossy dark green leaves is well worth culti- 
vation. If once established it would probably endure the very trying conditions of 
low altitudes in the southern part of the State. It grows naturally in crevices of lime- 
stone cliffs and probably would need an open soil containing considerable disinte- 
grated limestone. Its large scarlet beans are said to be poisonous, which would be 
a drawback to its use as a decorative plant.
