SAXIFRAGACEAE. 75 
JAMESIA. 
(Family Saxifragaceae). 
Shrubs: deciduous. Twigs 
rounded or slightly 4-sided, with 
quickly exfoliating bark: pith 
moderate, rounded, pale brown, 
continuous. Buds_ solitary, ses- 
sile, with 1 pair of white-hairy 
scales, the terminal rather large, 
the lateral small or suppressed. 
Leaf-scars opposite, narrowly U- 
shaped, white-ciliate, low, meeting: 
bundle-traces 3, small:  stipule- 
sears lacking. (Hdwinia). 
Winter-studies of Jamesia 
americana are given by Schneider, 
f. 190. 
The woody genera which are as- 
sembled here as representing the 
family Saxifragaceae in accord- 
ance with the views of excellent 
botanists, are considered by others 
to differ too greatly for this union 
with the herbs, to which they would restrict the name Saxi- 
fragaceae. These authors employ the family name Iteaceae 
for the genus Jtea, Grossulariaceae for Ribes, and Hydran- 
geaceae for the remainder. 
Both Jamesia and Edwinia commemorate Edwin P. James, 
the discoverer of the plant. The first had been used earlier 
for what is not considered a tenable genus: the second was 
given under the principle that a name once used pertains 
always and exclusively in its first meaning. 
Twigs at first light brown and hairy. J. americana.
