measuring herbarium specimens

Depends on how long it is.  A flexible ruler can be used unless it is really tightly curved.  You can always fit a piece of string to the curve and measure the string.  And, there is a gizmo (I can't recall the name) that has a little wheel that keeps track of distance as it is rolled along (just like the ones used by surveyors).  I once used such a device to record lengths of shorelines from maps (too many years ago to want to count).  Or, you can get a digitizing tablet with a "mouse" that will let you trace lines and store the length of the traced line.
