DO]WNINGIA. 



[Dedicated by Doct. Torrey, to tlie late A. J. Downing.] 



Downingia Regans, Elegant Downingi.% A beautiful 

 tender annual, with delicate foliage, and rich blue flowers 

 in great profusion ; six inches high ; in July and August. 



D. pulchella, 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 a rich 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. 



DRACOCEPHALUM. DRAGON'S HEAD. 



[From Greek words, signifying a dragon's head, because the flowers are fan- 

 cied to resemble one.]

 pink flowers ; in July and August.
