52 ADDISONIA 
When in flower this plant presents an exceedingly beautiful 
object. The myriads of bright-colored flower-heads spreading in 
all directions often nearly hide the rest of the plant from view. 
Another species of Pithecolobium grows naturally in Florida. 
It is Pithecolobium Unguis-cati or, as it is popularly known, 
cat’s-claw. Both the botanical name and common name have 
reference to the spines with which the plant is armed. The black- 
bead received its common name from the small bead-like seeds it 
bears. It and the cat’s-claw grow together on the Florida Keys; 
but the cat’s-claw alone extends northward on the western coast of 
the peninsula, while the black-bead alone occupies the eastern coast. 
The specimen from which the accompanying illustration was 
made was brought to the New York Botanical Garden from southern 
Florida by N. L. Britton in the spring of 1904, and flowered in the 
conservatories in November, 1907.
