Sapotaceae Sideroxylon (Bumelia) lanuginosum ssp. oblongifolium
Sideroxylon lanuginosum Michx. ssp. oblongifolium (Nutt.) T.D. Pennington

This species has a more southern (ssp. lanuginosum) and western (ssp. oblongifolium) range, compared to lycioides, but overlapping (FNA 8, K). It may be more concentrated in relatively mesic habitats, where ranges overlap (W). S. lanuginosum differs in having persistently hairy twigs and wooly-tomentose leaves (versus more or less glabrate), and smaller fruits (ca. 6-8 mm long versus 10-15 mm). Ssp. oblongifolia occurs widely in the lower Mississippi watershed, but has not been verified in Ky. or Tenn. (Ch, K). It was reportedly collected ca. 1979 by R. Hannan & L. Phillippe (KSNPC) at Floyd's Woods in MCLE, but the plant has not been relocated in the herbarium or field (M). Early records of the largely maritime southeastern species, S. tenax L., might have been based on lanuginosa (M). There has been some confusion among these and other taxa, especially in regions of overlap, and hybridization is suspected; see keys and notes in FNA 8, Y and W.
