 S. Eu. B.M. 27. — One of the best annuals for the home 

 border. Each plant covers a ground space of 2 ft., and 

 blooms continuously throughout the summer. Flowers 

 remain open all day during pleasant weather. There 

 are many variously striped and spotted forms of this 

 popular annual, none of which surpasses the type in 

 beauty. A variety with pure white fls. is attractive. 

 Other well marked horticultural forms are : Var. vit- 

 tita, prettily striped with blue and white. F.S.3:298. 



from seed : stem trailing or twining, 4-5 ft. long : fls. 

 golden. Valuable as a greenhouse climber and for

COOPfiEIA (after Joseph Cooper, English gardener). 

 .\iniiriiUiih'ii-i'ip. A genus of only two or three species 

 iif ttiicicr. Ijullious plants from Texas, with the habit of 

 Zephyrauthes but night-blooming (which is anomalous 

 in the order), and with erect anthers, while those of the 

 latter are versatile. The Hs. are fragrant, solitary, 2 in. 

 or more across, waxy-white, tinged red outside, and 

 more or less green within. The Ivs. appear with the fls. 

 in summer. They are long, narrow, flat and twisted. 

 The bulbs should be taken up in autumn and stored 

 during the winter in dry soil. Culture easy and like 

 Zephyranthes. Lately a new and little-known plant 

 has been offered by the trade, C. Oberwetteri, with 

 "bright green " fls.
