The annual species of Datura are readily grown from 

 ^ **"■ seeds sown on a hot-bed ; the young plants being transferred 

 singly, as soon as possible, to small pots, preparatory to transplanting to 

 the open border. The shrubby species — Brugmansias — are propagated 

 by means of cuttings, made from the young shoots taken in spring, with 

 a heel of older wood. These are inserted in sandy soil and treated to 

 bottom heat. Any light sandy soil will suit the whole genus. The 

 shrubby section require greenhouse treatment, giving them a fair 

 amount of heat in summer, but much less in winter, when their chief 

 requirements are to be kept cool and dry. They should be severely 

 pruned every spring. They may be planted out to form large specimens 

 or grown in pots as standards. During the flowering period food should 

 be supplied in the form of manure water.

 spoon-shaped, so deeply cut as to make the calyx almost five-parted. 

 The corolla is funnel-shaped ; and the five unequal stamens are attached 

 somewhere about the middle of the tube. The two-celled ovary supports
