Notes On Neotropical Amanoa (Euphorbiaceae), W. John Hayden
Notes On Neotropical Amanoa (Euphorbiaceae), W. John Hayden
Biology Faculty Publications
Lectotypes are designated for Amanoa caribaea Krug & Urban and A. guianensis Aublet; presumed syntypes of the latter taxon are shown to be heterogeneous by inclusion of a previously unrecognized species. Four new species of Amanoa are described: A. congesta from French Guiana and northeastern Brazil; A. gracillima from Manaus, Brazil; A. nanayensis from Amazonian Peru and adjacent Colombia and Brazil; and A. neglecta from French Guiana and Surinam. Amanoa sinuosa is proposed as a new name for the later homonym A. robusta Leal. A key to the 13 neotropical species is presented.
Dudleya Cymosa Subsp. Costafolia (Crassulaceae), A New Subspecies From The Southern Sierra Nevada, Tulare County, California, Jim A. Bartel, James R. Shevock
Dudleya Cymosa Subsp. Costafolia (Crassulaceae), A New Subspecies From The Southern Sierra Nevada, Tulare County, California, Jim A. Bartel, James R. Shevock
Aliso: A Journal of Systematic and Floristic Botany
Dudleya cymosa subsp. costafolia, a new subspecies from the southern Sierra Nevada, Tulare County, California, is described and illustrated. Along with bright yellow flowers, the cespitose plant produces numerous, small rosettes with rib-shaped linear to linear-oblanceolate leaves, which are unique to the subspecies. The authors have searched numerous other rock outcrops, especially limestone, in the general area for additional plants with no success. Dudleya cymosa subsp. costafolia evidently is restricted to a solitary limestone outcrop north of the South Fork of the Middle Fork of the Tule River.
Monardella Stebbinsii (Lamiaceae), A New Serpentine Endemic Species From The Northern Sierra Nevada, Plumas County, California, Clare B. Hardham, Jim A. Bartel
Monardella Stebbinsii (Lamiaceae), A New Serpentine Endemic Species From The Northern Sierra Nevada, Plumas County, California, Clare B. Hardham, Jim A. Bartel
Aliso: A Journal of Systematic and Floristic Botany
Monardella stebbinsii (Lamiaceae ), a new species from the northern Sierra Nevada of Plumas County, California, is described and illustrated. Characterized by ovate leaves, multiple verticillasters per infiorascence, a matlike habit, reddish papery bracts, and purplish-red leaves with a soft white pubescence, the species is not closely related to any other species of the genus. The new species is apparently restricted to the central portion of a serpentine outcrop located north and east of the confluence of the North Fork of the Feather River and its East Branch.
