Diptych

A very simple narrative, a diptych, a pastoral in which the author narrates the birth of Christ […] first as it has impressed the rich countryman Asveer, then as it has been seen by the skeptic Nicodemus.

“Vegetation of the Sonoran Desert” is the first volume of a diptych “Vegetation and Flora of the Sonoran Desert,” for which Ira L. Wiggins is to write the companion volume on the flora.
