Sabal minor
Common name
blue-stem palmetto, dwarf palmetto
Description
Stems: Solitary, subterranean, rarely growing upright to 2 m tall. Leaves: Minorly costapalmate,costapalmate:
a fan-shaped leaf with a midrib (costa) extending into the blade, sometimes extending far enough into the blade to cause it to curve (e.g., <em>Sabal palmetto</em>)
, induplicate,induplicate:
Most palm leaflets or leaf segments are obviously folded. If the folds create a V-shape, with the midrib lower than the margins (so that rain might fall "into a valley"), the folding is induplicate.
, grayish green, circular, almost in a single plane or slightly folded, segments stiff and split about half the length of the blade with few or no fibers between segments, tips slightly bifid. Leaf split almost to the costa,costa:
mid-rib or vein
, dividing the blade nearly in half. Petiole unarmed. Flowers and fruits: Inflorescence sparsely branched to two orders, longer than leaves. When ripe, fruits are spherical to ovoid, brown or black drupes to 6-10 mm long.

May be confused with

a fan-shaped leaf with a midrib (costa) extending into the blade, sometimes extending far enough into the blade to cause it to curve (e.g., <em>Sabal palmetto</em>)
, with abundant marginal fibers
Distribution
Native to the southern United States from North Carolina to Texas and northeast Mexico
