|discussion=<p>The low, broad fruit of <i>Allionia choisyi</i> resembles a small, clinging tick, hence the Spanish name “garapatilla.” Occasionally the fruits are strongly convex, others may have four moderately slender teeth; in either case the fruits are intergradient to the few-toothed, strongly convex fruits of <i>A. incarnata</i>. Such plants are most commonly found in southeastern Arizona and in arid south-central Texas. Plants with fruits shaped as those in <i>A. choisyi</i>, with glands on the concave surface with tall stalks but with entire or nearly entire, curved, lateral ribs occur occasionally in South America. Collectors have noted that <i>A. choisyi</i> plants hug the ground more closely than those of <i>A. incarnata</i>. Throughout much of its range in North America, <i>A. choisyi</i> has leaves with strongly pleated-undulate blades. Very small, pale pink to white flowers are also more common in <i>A. choisyi</i>, especially in Mexico.</p><!--
--><p>In the flora area <i>Allionia choisyi</i> is usually an annual. In Mexico, plants often appear to be perennial.</p>
