HYMENOOALLIS. 133 



Hymenocallis, 



A very handsome genus of Amaryllidaceous plants, requir- 

 ing stove temperature to grow them in. They are admirably 

 adapted for cutting purposes where fine, sweet-scented, pure 

 white flowers are required. They should be grown in a 

 compost of loam and sand with a little leaf mould added. 

 There are several other species in cultivation, but those 

 enumerated below will be found the most useful for general 

 purposes. They are generally found in gardens under the 

 name of Pancratium, but these two genera are now proved to 

 be quite distinct. 



H. fragrans. — This, the freest flowering species, should be 

 grown by every one. The leaves are braadly-lanceolate from 

 eighteen to twenty-four inches in length and four to six inches 

 in breadth. Flowers produced in many flowered umbelf, 

 pure white in colour, and deliciously sweet-scented. Native 

 of West Indies. 



H. macrostephana. — A very beautiful species, having leaves 

 two to three feet long, two to three inches broad ; flowers 

 produced in umbels, containing six to ten blooms, pure white, 

 sweet-scented, corona funnel-shaped, two inches long by about 

 two inches in breadth ; segments linear, half an inch broad. 



H. speciosum. — This species is similar in habit to the 

 above, the leaves being, however, broader and less undu- 

 lated at the edges. It produces umbels of large pure white 

 flowers with long and gracefully arched segments, which are 

 broader and have more substance than H. fragrans. Native 

 of West Indies. 



Impatiens. 



To this genus belong many beautiful species, some of 

 which have been introduced to our gardens, but again lost.
