Leaf Leaf blades in Hapaline are either thin-textured or thick and leathery. They vary in shape from ovate to hastate. Posterior lobes are present in all species, although lacking from some individuals of H. appendiculata Ridl. Hapaline displays two distinct growth types which are linked to the thickness of the leaf blades.
New growth is marked by leaf emergence and abundant flowering.
Leaf blade variegation, in the form of irregular and diffuse silver grey to pale green blotches, has been reported in H. appendiculata , H. benthamiana , H. brownii and H. colaniae . All Hapaline species have white spathes occasionally tinged green or greyish pink. The spathe is always divided into two zones with the upper part flattened and erect to reflexed and the lower part clasping. The inflorescence is borne on a short to long, green to grey-pink mottled peduncle. After fertilization it thickens and bends downwards, bringing the developing fruits to soil level.
