 DRIMIA. 



A small genus of uninteresting Cape of Good Hope 

 bulbs formerly included in the genus Lachenalia. The 

 flowers are small and not conspicuous. This genus is 

 only mentioned, like many others, to caution amateurs 

 against its cultivation. 



DUTCH BULBS, OR HOLLAND BULBS. 



This term is applied by the trade, to such bulbs as 

 are largely grown in Holland, and includes Hyacinths, 

 Tulips, Crocus, Crown Imperials and Narcissus, all but 

 the latter being grown almost exclusively in that country. 



ELISENA. 



This genus contains but one cultivated species, E. 

 longipetala, a native of Peru, and allied to Pancratium. 

 The flowers are borne in clusters on a slender scape 

 nearly three feet in height, and closely resemble those of 

 the Ismene. Its pure white, delicately formed flowers, 

 have a pleasing fragrance, and are worth all it costs to 

 produce them. They require greenhouse treatment, to 

 be kept very wet when in active growth, and perfectly 

 dry when at rest. 



ERANTHIS. 



Winter Aconite. 



A small genus of tuberous-rooted, hardy herbaceous 

 plants, natives of Italy and Siberia.
