Columnea pilosa Van Houtte, ca 1840	Columnea pilosa Van Houtte, ca 1840s

These prints appear to be from the same plate, but in different editions of Horto van Houtteana -- note the inverted curve of the publication name to the left, and the slightly different arrangement of the text at the bottom.  I find the differences in the hand coloring used to finish the two plates particularly interesting.
