Sideroxylon lycioides is characterized generally by elliptic leaves and glabrous twigs and leaves. Varieties and segregate species have been recognized based on variation in leaf size and shape, leaf apex, and fruit size and shape. As observed by A. Cronquist (1945c), most of these characters exhibit continuous variation among collections throughout the range of S. lycioides. Because of this pattern of variation without marked morphological gaps, we recognize no infraspecific variants. T. D. Pennington (1990) proposed that S. lanuginosum, S. lycioides, S. reclinatum, and S. tenax are closely related and that this complex of species is morphologically distinct from neotropical species of Sideroxylon.
