New combinations, rank changes, and nomenclatural and taxonomic comments in the vascular flora of the southeastern United States. II
As part of ongoing efforts to understand and document the flora of the southeastern United States, a number of taxonomic changes at generic, specific, and infraspecific rank are made. We also discuss
A step‐by‐step protocol for meiotic chromosome counts in flowering plants: A powerful and economical technique revisited
TLDR
A detailed protocol for choosing, staining, and squashing angiosperm pollen mother cells will hopefully demystify and reinvigorate a powerful and once commonplace botanical technique that is available to researchers regardless of their location and resources.
New combinations, rank changes, and nomenclatural and taxonomic comments in the vascular flora of the southeastern United States. IV
As part of ongoing efforts to understand and document the flora of the southeastern United States, we propose a number of taxonomic changes and report a distributional record. In Rhynchospora
A clarification of the name Carex hypsipedos C.B.Clarke (Cyperaceae) and a new name for the South American Carex section Acrocystis taxon
TLDR
Details of Carex hypsipedos from Peru, corresponding to Clarke’s original description, are provided, and the Carex sect.
Studies in the vascular flora of the southeastern United States. VII
As part of ongoing efforts to understand, document, and conserve the flora of southeastern North America, we propose two new species, the recognition of a usually synonymized variety, the acceptance
The true identity of Marshallia grandiflora, an extinct species, and the description of Marshallia pulchra (Asteraceae, Helenieae, Marshalliinae)
TLDR
Morphologic and biogeographic data clearly separates two species within the previous concept of M. grandiflora and M. pulchra, and Cytological data is given for M. legrandii, including the first report of B-chromosomes in the genus.
2'-hydroxy-5,9-dimethyl-2-(3-methyl-2-butenyl)-6,7-benzomorphan (pentazocine) hydrochloride hydrate.
TLDR
A comparison of the bond lengths and torsion angles shows a side-chain orientation similar to that of cyclazocine but unlike that of naloxone.
Observations on the Relationship Between Above- and Below-Ground Anthocyanin Production in Galax urceolata (Poir.) Brummitt Growing in Sun-Exposed and Shaded Locations
TLDR
Significant more anthocyanins in leaves and rhizomes of plants from sun-exposed locations compared to plants from shaded locations, but no differences in carbohydrate concentrations are found, contradict the paradigm that light is always required for Anthocyanin production, and suggest the possibility of some form of communication between leaves and Rhizomes with respect to anthOCyanin content.
NEW EXOTIC ADDITIONS AND OTHER NOTEWORTHY RECORDS FOR THE FLORA OF NORTH CAROLINA
Thirty exotic taxa are reported from northwestern Nor th Carolina. These taxa are either new additions to the vascular flora of the state, provide voucher substantiation for reports in Weakley
Taxonomy and geographic distribution of Carex lucorum var. austrolucorum (section Acrocystis, Cyperaceae)
TLDR
Based on multivariate analyses and analyses of variance of measured characters, allopatry, and previous studies revealing differences in achene micromorphology, chromosome differences, and flavonoid chemistry,Carex lucorum is elevated to species status as C. austrolucorum.
