effect among Andromedas and similar shrubs. The flowers are 

 snowy white, and are produced in pyramidal spikes 2ft. to 3ft. 

 high. These bulbs, which should be planted in late summer, 

 should not be interfered with except for purposes of increase. 



Pancratium (Sea Daffodil). — Only one species of this genus 

 is really hardy, and that in favoured situations, such as ad- 

 vocated for Crinums. Indeed, P. illyricum may very well be 

 treated on the lines suggested for the Crinums. Increased by 

 offsets in autumn.

 Valley is the genus here named, several species of which might

 P. imiltifloruin (Fig. 226), the last two having double forms. Though 

 the flowers cannot boast striking colour, they are neat in the 

 extreme, and are, moreover, disposed in such a way that they

 ribbed with red ; and P. pimctatum, white, lilac-dotted. There
