Population Divergence and Evolution of the Hawaiian Endemic Sesbania tomentosa (Fabaceae)

Figure 1. Examples of several Sesbania tomentosa morphotypes examined in this study, identified by geographical population: (A) trailing lower branches in ash dunes at Pepeiau, Hawai‘i; (B) slender erect stems at Kū‘ē‘ē, Hawai‘i; (C) long pale green-grey leaflets and orange flowers at Waiaka‘īlio, Hawai‘i (M. ); (D) deep red flowers at Pu‘u Koa‘e, Kaho‘olawe (K. Wood); (E, F) Hylaeus bee exiting flower and dissected flower showing stigma and stamens from Kīpuka Nēnē (M. ); (G) small arborescent at Pu‘u Pīmoe, Maui; (H ) large arborescent at Kawela, Moloka‘i; (I) silky leaves and procumbent growth at Mo‘omomi, Moloka‘i; (J) pale red flowers and glabrous leaves at Mānā, Kaua‘i (D. Burney); and (K) erect shrub at Polihale, Kaua‘i (N. Tangalin). Photographs by D. Cole unless otherwise noted.
