Discussion

The undifferentiated marginal cells of the leaf base and the large abaxial solid papillae near the leaf tip distinguish Aloina hamulus from A. rigida, which, in addition, has a strongly twisted and longer peristome. The ovoid-cylindric capsule and abaxially papillose leaves distinguish this species from A. aloides var. ambigua. Young leaves should be checked when papillae are not evident in mature leaves.
