This genus was established by M. Cavanilles, a 
Spanish botanist of the last century, in honour of his 
countryman Lopez. Coronata, from the Latin, in 
allusion to its crown of flower buds. 
This pretty annual exhibits its delicate blossoms 
when only two or three inches high; and continues 
growing, flowering, and seeding, till it attains the 
height of as many feet. 
The protection of the anther is very nicely ef- 
fected by its enclosure in a little white appendage, 
growing immediately beneath it; an appendage 
which Linneus would call a nectary; a distinction 
we prefer to either petal or abortive stamen. When 
the flower opens, the stamens acquire a tendency to 
rise ; whilst the nectary, clasping the anther, as per- 
tinaciously holds it down ; till at length the warmth, 
by contracting the exposed parts of each antagonist, 
occasions the stamen to extricate itself with a spring 
or leap. As this liberation occurs when the anther 
is matured, its sudden action serves to disperse the 
pollen. 
Sow seeds in the borders in March. Those shed 
from the plant frequently vegetate in spring.
