SILVA OF NORTH AMERICA. 
RUBIACEX. 
Two species are found within the territory of the United States; one 
of these is a small tree, and the other a shrub‘ which also inhabits the West Indies and Mexico. 
Guettarda has few useful properties. 
The bark of some of the American species is occasionally 
employed as a tonic and febrifuge, and the powdered bark of the Old World species has been found 
valuable in the treatment of ulcers and wounds.’ 
A few of the species are cultivated for ornament, 
particularly Guettarda hirsuta, which is often planted in tropical gardens on account of the delightful 
fragrance of its pure white flowers. 
The genus was named for Jean Etienne Guettard,? a distinguished French botanist and min- 
eralogist.

8 Jean Etienne Guettard (1715-1786) was born at Etampes, and 
at an early age became distinguished for his observations on the 
habits of plants, which obtained his admission into the Académie 
des Sciences in 1743 and made him known to Linneus. Later he 
abandoned botany and devoted himself entirely to mineralogy, which 
he studied in many European countries. Guettard was one of the 
first naturalists to appreciate the value of mineralogical maps, of 
which he constructed several. He is the author of Observations 
sur les Plantes, published in two volumes in 1747, of five volumes of 
Mémoires sur differentes parties des Sciences et Arts, and of many 
papers published in the Memoirs of the French Academy.
