DOWNINGIA. 
{Dedicated by Doct. Torrey, to tle late A. J. Downing.J 
Downingia élegans.—Elegant Downingia.—A beautiful 
tender annual, with delicate foliage, and rich blue flowers 
in great profusion ; six inches high; in July and August. 
D. pulchélla.—Pretty Downingia.—It is a pretty flow- 
ering tender annual, of very humble growth, only rising 
a few inches high. The flowers are rather larger than D. 
elegans, blue, with a broad white spot at the centre, 
stained with arich yellow. The flower is about half an 
inch across. Its delicacy of growth will prevent its 
spreading rapidly through the country. 
When grown in pots in the green-house, both are very 
beautiful. 
The Downingias are natives of California and are gen- 
erally called Clintonia, by florists; a name given by 
Douglas, who did not know that it had already been ap- 
plied to another genus.
