Dr. Gray recognizes six North American species of this 
genus: A. ¢triloba, Dunal; A. parviflora, Dunal; A. grandifiora, 
Dunal; A. cuneata, Shuttleworth, (which is probably A. reticu- 
fata, Chapm.);.A. angustifolia, n. sp., (Uvaria pygmea, Torr. 
and Gray, in part), and A. pygme@a, Dunal. The fruits of the 
southern shrubby species have been but rarely collected, and are 
much needed in herbaria. The petals of Aszmina are not truly 
valvate in aestivation.as was formerly supposed, but when fully 
grown their summits are more or less imbricated.

This is an amusing and interesting account of personal ex-_

Near the mouth of San Telmo Cajion were found “ beautiful 
specimens of Dr. Parry’s Harfordia,” and localities for many 
other interesting plants are noted.
