imposing in comparison with transplanted beds or groups; they also commence 
flowering as the early bulbs are fading, a season when there very generally exists a 
^scarcity of flowers out of doors for a month. When sown in summer, they do not 
last long, the generality of their roots being small and fibrous ; they are, in conse- 
quence, apt to get scorched by the sun ; but when sown in autumn or very early in 
the spring, they allow the season to get sufiiciently advanced for substituting in 
their stead Geraniums, Petunias, &c. ; these, if well selected, will last the whole 
season. We kept some plants of CoUinsia hicolor in pots during the winter, and 
they looked exceedingly lively through the months of February and March, a 
desirable addition at that season. 
The genus is dedicated, by Dr. Lindley, to the name of Mr. Zaccheus Collins of 
Philadelphia, a gentleman of talent as a Botanist and Mineralogist. The specific 
name hicolor alludes to the two distinct colours in the flower, viz., the dark blue of 
the lower lobes of the corolla, and white of the upper.
