Strong Commelinaplants, about 40-70 days old should be put in bright light for 1-2 hours enclosed in a polythene bag.
Select a leaf from a Commelinaplant and use the scalpel to cut out a piece of leaf about 5mm wide and 20 mm long, avoiding the midrib, as shown in the diagram.

What is the derivation of the name of the genus Commelina?
Linnaeus wrote "Commelina has flowers with 3 petals, 2 of which are showy, while the third is not conspicuous, from the 2 botanists Commelin, for the third died before accomplishing anything in botany.

Asiatic Dayflower, Commelina communis(Site not responding. Last check: 2007-07-10)
There are also three native Carolina species of Commelina, all of which at least superficially resemble Asiatic Dayflower.
It is this "community" growth pattern (below right) that gives rise to the scientific epithet of C. communis.
The genus name Commelina recognizes the work of Dutch botanists Johan and Caspar Commelin, brothers represented by the two large blue petals; in a sort of botanical cruelty joke, a third brother who made no scientific contributions is memorialized by the dayflower's insignificant third petal.
