--><p>In the following keys and descriptions, three trichome types are defined as follows. Simple grappling-hook trichomes have a cylindric stalk that is unbarbed except at the apex, which terminates with four (or sometimes fewer) retrorse barbs. Complex grappling-hook trichomes have a tapered stalk that is retrorsely barbed along its length and capped usually by four retrorse barbs. Needlelike trichomes have swollen bases resting on a pedestal formed by a ring of epidermal cells, are relatively long and pointed, and bear antrorse barbs or knobs along their length.</p><!--
--><p>Leaf blade intersinus distance is measured across the leaf blade between opposite sinuses; for leaves with entire margins, it is the width of the leaf blade. Anther papillae and seed coat anticlinal wall shape can be observed at 10/x magnification; greater magnification (30–40/x) is needed to see seed coat cell papillae in species with numerous small papillae.</p>
