|discussion=<p><i>Aloina bifrons</i> is readily identified by the hyaline hair of the leaf apex and the poorly developed costa that is only evident toward the leaf base, but inconspicuous in the distal half of the leaf. No other North American species of the genus exhibits a piliferous leaf apex.</p>
