material in the Kew Herbarium, however, shows hat the two 
species are not nearly related.

This plant is the source of the Mexican “ lignum nephriticum,” 
a wood celebrated in Europe from the sixteenth century. 
Remarkable fluorescent phenomena are displayed by an infusion 
of the wood, to which various medicinal virtues have been 
attributed. A complete account is given by W. E. Safford,
