  • Artificial hybridization in Hawaiian Wikstroemia (Thymelaeaceae)
    American Journal of Botany, 1991
    Co-Authors: Stephanie S. Mayer
    Abstract:

    Crosses were performed within and between 19 Hawaiian populations of the mostly dioecious woody shrub Wikstroemia. These populations are from a variety of habitats on the six major islands and are morphologically diverse. The populations are referrable to eight of the 12 species recognized by Peterson. Almost all hybrid combinations produced seeds, and seed-set was not significantly different among three categories of hybrids (within population, between populations on the same island, and between populations on different islands).

  • Nomenclatural Notes on American Thymelaeaceae
    Novon: A Journal for Botanical Nomenclature, 2010
    Co-Authors: Zachary S Rogers
    Abstract:

    The nomenclatural status of all published plant names applicable to American Thymelaeaceae at the rank of genus and below is evaluated. Thirty-two of the 256 published names at specific and infraspecific ranks require effective typifications. Lectotypes are designated for 29 names: Daphne lagetto Sw., D. macrophylla Kunth, D. occidentalis Sw., D. pillopillo Gay, Daphnopsis bogotensis Meisn., D. brasiliensis Mart., D. caracasana Meisn., D. caribaea Griseb. var. ecuadorensis Domke, D. coriacea Taub., D. decidua Domke, D. ekmanii Domke, D. ericiflora Gilg & Markgr., D. longifolia Taub., D. longipedunculata Gilg ex Domke, D. longiracemosa Gilg ex Domke, D. martii Meisn., D. purpusii Brandegee var. ehrenbergii Domke, D. racemosa Griseb., D. sessiliflora Griseb. ex Taub., D. zamorensis Domke, Goodallia guianensis Benth., G. guianensis var. parvifolia Benth., Lagetta funifera Mart. & Zucc. (epitype also designated), Linostoma albifolium Barb. Rodr., Lophostoma bolleanum Domke, Schoenobiblus coriaceus Domke, S. daphnoides Mart., S. ellipticus Pilg., and S. peruvianus Standl. Neotypes are designated for three names: Daphnopsis crassifolia (Poir.) Meisn. var. eggersii Krug & Urb., D. pseudosalix Domke, and D. selerorum Gilg.

  • a revision of malagasy gnidia Thymelaeaceae thymelaeoideae 1
    Annals of the Missouri Botanical Garden, 2009
    Co-Authors: Zachary S Rogers
    Abstract:

    Abstract A systematic revision of Gnidia L. is presented based on an analysis of morphological data. The circumscription of the genus adopted here includes Lasiosiphon Fresen. and excludes Atemnosiphon Leandri and Dais L. Six new combinations are made for species previously recognized as Lasiosiphon: G. ambondrombensis (Boiteau) Z. S. Rogers, G. hibbertioides (S. Moore) Z. S. Rogers, G. humbertii (Leandri) Z. S. Rogers, G. linearis (Leandri) Z. S. Rogers, G. occidentalis (Leandri) Z. S. Rogers, and G. perrieri (Leandri) Z. S. Rogers. Two names, G. daphnifolia L. f. and G. linearis, are resurrected from synonymy with L. madagascariensis (Lam.) Decne. and L. decaryi Leandri, respectively, and now pertain to more broadly circumscribed species. One new species, G. neglecta Z. S. Rogers, is described. These changes result in the recognition of 14 species, all endemic, making Gnidia the largest genus of Malagasy Thymelaeaceae. Lectotypifications are provided for 15 names: Dais gnidioides Baker, G. danguyana Lea...

  • daphne hekouensis Thymelaeaceae a new species from china
    Annales Botanici Fennici, 2008
    Co-Authors: Meide Zhang, Zachary S Rogers, Yumin Shui, Wenhong Chen, Rongmei Zhang
    Abstract:

    Daphne hekouensis H.W. Li & Y.M. Shui sp. nova (Thymelaeaceae) from China (Yunnan Province, Hekou County) is described and illustrated. The new species with its axillary inflorescence and 5-lobed white calyx tube is most similar to D. axillaris, but can be easily distinguished by the larger leaves (13-21 X 5-8 cm), longer calyx tubes (15-25 mm), larger-elliptic or oblong calyx lobes (10-15 x 3-4 mm), and upper whorl of stamens located 3-4 mm below the mouth of the tube.

  • typification of plant names in Thymelaeaceae published by linnaeus and linnaeus filius
    Taxon, 2006
    Co-Authors: Zachary S Rogers, Mark A Spencer
    Abstract:

    Twenty four lectotypes, and three neotypes are designated for 27 plant names (25 at species rank and two at varietal) belonging to the family Thymelaeaceae and published by Linnaeus and Linnaeus filius. Epitype specimens are designated for three of the lectotypes. Of the species names, three were first published by J. R. & G. Forster and became the nomenclatural basis of names adopted by Linnaeus filius. All type choices made here are intended to support current usage of their respective names.

  • a new species of malagasy gnidia and the lectotypification of octolepis decalepis Thymelaeaceae
    Adansonia, 2006
    Co-Authors: Zachary S Rogers
    Abstract:

    Deux recoltes recentes de la foret de Bemangidy-Ivohibe (SO de Madagascar, N de Fort-Dauphin) representent une espece non decrite de Gnidia L. (Thymelaeaceae). Cette nouvelle espece, decrite ici sous le nom G. razakamalalana Z.S.Rogers, se distingue particulierement des autres especes malgaches de Thymelaeaceae par ses tres longs tubes floraux organises en inflorescences terminales uniflores. Une illustration et le statut provisoire de conservation accompagnent la description. Une lectotypification est egalement indiquee pour Octolepis decalepis Gilg (Thymelaeaceae), synonyme taxonomique de la variete africaine continentale O. casearia Oliv. var. casearia.
