The name of the genus now before us is derived 
from the Greek words, leptos, slender; and siphon, 
a tube. Its application is evident. 
This is a very pretty newly-introduced annual, 
of humble growth, varying in the colour of its 
flowers, from white to pale pink or purple. It is a 
valuable little plant for flowering early in the sum- 
mer from autumn-sown seeds. The past winter 
has been severe, and most unfavourable to tender 
plants, notwithstanding which we have healthy seed- 
lings of it, growing in an exposed situation, from 
seeds which had been shed from a flowering plant 
last autumn. This may be considered as ample 
proof of its power to withstand any vicissitudes of 
winter ; but the heat of summer, in a dry soil, is 
not very congenial to its luxuriance, therefore a 
rather shady situation should be chosen for spring- 
sown plants, which are intended to flower in Au- 
gust. 
The physiologist may be recommended to exa- 
mine the leaves of this plant, which are deeply di- 
vided into segments, always consisting of an even 
number, as four, six, eight, &c.
