Arb. Alpina , Blackberried Alpine Arbutus; with

Hydrangea. Gen. char. — -Cal. five cleft ; coi 5 . five 
petaled ; caps, two- celled, two-beaked, inferior, open- 
ing between the styles. 
Hyd. Arhorescens, Shrubby Hydrangea ; with a 
woody stem. A native of Virginia, and long an inha- 
bitant of some gardens in England. 
Hyd. Hortensis, Garden Hydrangea ; with elliptical, 
serrated, very smooth leaves, and equal stamens. This 
magnificent plant, which, from being so common, ceases 
to be admired, is remarkable for the changes in the pro- 
gress of flowering. The blossoms are at first green, 
then rose- coloured, and, last of all, green a second 
time ; and the plant which has produced red flowers 
one year, shall send forth blue flowers the next, al- 
though treated in the same , manner. It is a native of 
China and Japan, where it is also cultivated for the 
sake of its beauty, and was introduced from China to 
the gardens at Kew in 1790.
