Actually, this is almost exactly the same in zoology.  The only difference
is, a lectotype in botany may be derived from the same *individual* as the
original type (in zoology, it would still be regarded as the holotype),
whereas in zoology the lectotype is selected from a series of specimens
examined by the original author (syntype series).  In other words,
lectotypification serves the same fundamental purpose in botany as in
zoology (selecting a name-bearer among material examined by the original
author), but the "units" of typification may differ (as in typification in
general).
