|discussion=<p>Species 1.</p><!--
--><p><i>Rhodotypos</i> is an Asian mesophytic shrub that shares several characteristics with the western North American desert shrub <i>Coleogyne</i>, including opposite leaves, 4-merous, terminal, solitary flowers, ovaries with lateral (adaxial) styles, and a distinctive inner, rimlike or sheathlike torus extension that surrounds the ovaries and occasionally bears some of the stamens. The fruit of <i>Rhodotypos</i> is drupelike during development, but dries at maturity while retaining a shiny, smooth exocarp; it can be considered a modified drupelet.</p><!--
--><p>With <i>Coleogyne</i>, <i>Kerria</i> and <i>Neviusia</i>, they form Kerrieae of subfam. Amygdaloideae, an alliance recognized by G. K. W. Schulze-Menz (1964) but in the Rosoideae.</p>
