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, 7. 
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.
