Barb Structure

Pennaceous at the upper tip with some plumulaceous (fluffy) structure near the base; barbs show noticeable wear and separation along the left vane

Rachis & Barb Pattern

Central rachis is slender, pale whitish-tan, slightly curved, and flexible; barbs are fine and of medium density
