== Plant structure ==
''K. beharensis'' is an evergreen shrub, tall.〔"Kalanchoe beharensis (Velvet leaf)." ''Backyardgardener.com.'' 5 May 2009 .〕 The stem is about long, and is slender and knotted. Leaves are olivaceous in color, triangular-lanceolate shaped, decussately arranged with leaf margins that are doubly crenate. Each leaf is about long and wide. The bottoms of the leaves are glabrous and they are covered with a woolly hair towards the apex. The leaf hairs are brown, and tips of the teeth are darker. The hairs on the stem, younger leaves, and petioles are white. A sign of older leaves is concavity on the upper surface. Inflorescences are high, forming a branched corymb. Flowers are on short pedicels (stalks). The calyx is 7 mm long with lobes that are oblong and acuminate. The corolla tube is urn shaped and 7 mm long.〔Jacobsen, Hermann. ''A handbook of succulent plants: descriptions, synonyms and cultural details for succulents other than Cactaceae.'' London: Blandford Press, 1960.〕 Blooming occurs from spring to summer, and flowers are small and yellowish.〔Lemke, Cal. “Kalanchoe beharensis - Elephant's Ear Kalanchoe.” ''University of
Oklahoma Department of Botany and Microbiology.'' 1998-2008. 1 May 2009 .〕 The type of trichome present on the leaves of Kalanchoe, vary among the different species. The different types of trichomes are an indicator of adaptation to a particular environment. On the leaf blade of the beharensis species there are tichomes of the non glandular, bushy three-branched type. This type of trichome is dead with evidence of tannin. Beharensis trichomes are also characterized by striped cuticular ornamentation on their surface. Glandular trichomes are also present on beharensis species leaves, with more on petioles than on leaf blades, and more on the top of the leaf as opposed to the bottom.〔Chernetsky, Mykhaylo, and Elizbieta Werysko-Chmielewska. “Structure of Trichomes from the Surface of Leaves of Some Species of Kalanchoe Adans.” ''ACTA Biologica Cracoviensia Series Botanica'' 47/2 (2005): 15-22.〕
