In 1788 Walter described three species ofSalix inFlora Caroliniana. HisSalix pentandra is the same asS. caroliniana, andS. alpina andS. occidentalis are the same asS. tristis Aiton (1789).Salix alpina is a later homonym ofS. alpina Scopoli (1722), and must be rejected, butS. occidentalis is the earliest legitimate name forS. tristis and takes precedence.
Morphological variation was analyzed in the endangeredBetula uber and sympatric dark-barked tree birches,B. lenta andB. alleghaniensis, to determine the extent of differences among the three taxa. Univariate and multivariate analyses of leaf and fruit characters indicated that the three taxa are morphologically distinct, thatB. uber is more similar toB. lenta than toB. alleghaniensis, that intermediates...
A new species,Simaba cavalcantei, is described and illustrated. It is considered to be intermediate between sectionsGrandiflorae andFloribundae and is distinguished from potentially sympatric species in a key to the species occurring north of the Amazon River.
One new name is proposed and eleven new combinations are made inCampomanesia andPimenta. Lectotypes are selected forC. eugenioides var.desertorum, C. phaea, andP. racemosa var.hispaniolensis, var.ouza, and var.terebinthina.
Salvia raveniana Ramamoorthy, resemblingS. purpurea Cav. [S. sect.Purpureae (Epling) Epling], but differing in deeply sulcate stem, long unbranched terminal racemes, many-flowered verticils, the nature and color of pubescence (very white) of calyx contrasting with a red corolla that dries purple, the reflexed, revolute lower lip of corolla, the number of papillae in the corolla tube (2), and the...
The synapotypic feature of seriate leaf cell papillae positioned on cell lumina and directed over the longitudinal cross walls alliesBryowijkia with the Trachypodaceae. The Hedwigiaceae consist of four closely related genera, and excludesRhacocarpus, a genus best placed in its own family, the Rhacocarpaceae. These taxa all belong in the Leucodontineae (Isobryales) and are not related to either the...
Twenty-two new varietal combinations are made for the treatment of the genusPanicum of the Southeastern United States. The following 3 new combinations are made in the subgenusPanicum:Panicum rigidulum var.elongatum, P. rigidulum var.pubescens, P. rigidulum var.combsii. The following 19 new combinations are made in the subgenusDichanthelium:P. strigosum var.glabrescens P. strigosum var.leucoblepharis, P. dichotomum...
A new tribe,Deppeeae, in subfamily Rubioideae Verdc. of the Neotropical Rubiaceae is described. It is easily distinguished by the presence of raphides, contorted or modified alternative aestivation of the corolla, numerous small ovules, and placenta attached to the middle of the septum. Three genera are known to be members of the tribe,Deppea, Schenckia, andOmiltemia. A hypothetical phylogenetic tree...
The nameSalix conifera Wangenh. is considered and its identity is shown to be the same as the hybridS. discolor × humilis. It is lectotypified by Wangenheim's figure supplemented by his description and diagnosis.
Chromosome number determinations were made from 407 wild or transplanted individuals and seedlings representing 65 taxa and hybrids inEuthamia andSolidago. The following are first reports:Euthamia remota, 2n=9II;Solidago leavenworthii, 2n=54;S. mollis, 2n=36;S. mollis var.angustata, 2n=36;S. rigida var.glabrata, 2n=9II;S. sempervirens var.azorica, 2n=9II; andS. sparsiflora, 2n=54. Most species have...
The University of Utah donated fungi from the A. O. Garrett Herbarium to the New York Botanical Garden (NY) in 1982. Most specimens are members either of the Ustilaginales or Uredinales (Basidiomycotina). Biographical data are given for some of the most important regional collectors represented: Albert O. Garrett, George L. Zundel, Seville Flowers, Marcus E. Jones, and Patrick J. O'Gara. Other contributors...
Malpighia romeroana var.nayaritensis is described from Nayarit, México, andM. albiflora subsp.antillana andM. nummulariifolia subsp.oblongifolia from the West Indies.
Four night-blooming water-lilies ofNymphaea subgenusHydrocallis,N. conardii, N. lingulata, N. novo-granatensis, andN. prolifera, are described from the American tropics.
A new species ofQuararibea, remarkable in its diminutive size, “palmoid” growth form, very large oblanceolate-obovate leaves, and cauliflory, is described and illustrated. (Se describe e ilustra una nueva especie deQuararibea, muy notable por su tamaño, diminuto, su forma de crecimiento palmoide, sus hojas oblanceoladas-obovadas y muy grandes, y su estado caulifloro.)
Dion tomasellii sp. nov. occurs with an interrupted distribution from Guerrero to central Sonora. It is characterized by falcate to subfalcate leaflets. The populations from Sonora and northern Sinaloa are segregated asD. tomasellii var.sonorense on the basis of their narrower and glaucous leaflets.
Retrorsely barbed aristae on a few immature disk achenes ofCoreopsis insularis (Brandegee) S. F. Blake, together with its other characters, suggest that the species would be better treated asCoreocarpus insularis.
Mimosa dalyi is described from eastern Bolivia, figured, and shown to be a carpologically modified member of seriesLeptostachyae, but also congeneric withSchranckiastrum. The defective protologue ofSchranckiastrum is analyzed and its one species transferred toMimosa asM. insignis (Hassler) Barneby.
