897. Symphyotrichum Vahlii

Abstract

SummarySymphyotrichum vahlii (Gaudich.) G. L. Nesom (Compositae: Astereae: Symphyotrichinae) is described and illustrated, and the species is provided with an expanded synonymy that includes type citations, known types, and supplementary comments. Notes are provided on cultivation and propagation. Comments are also made on the historical collections representing this species, both as types and early collections, and relating these to early circumnavigations. The likelihood that Thinobia araucana Phil., of the monotypic Thinobia Phil., is this species is also discussed.

1078. Solidago nemoralis Aiton: Compositae

“…Although Solidago nemoralis is a relatively late flowerer, and is almost one of the last prairie plants at Wakehurst Place in flower, it partly coincides with several other Compositae, and in a border setting can contrast well with a number of lilac/rose/purple‐flowered species listed by Hind (2023), such as the later flowering Vernonia missurica Raf. (see Hind & Langhorne, 2023), Eurybia spectabilis (Aiton) G. L. Nesom (see Hind & Lambkin, 2023a), Symphyotrichum laeve (see Hind & Lambkin, 2023b), Liatris aspera Michx. (see Hind & Lambkin, 2023c), and several others.…”

“…Along with Eryngium yuccifolium Michx. (Umbelliferae) (see Rix & Lambkin, 2023), it stood tall above much of the remains of most prairie plants along with a few plants of other members of the Compositae, Symphyotrichum laeve (L.) Á. Löve & D. Löve (see Hind & Lambkin, 2023), Coreopsis lanceolata L. (see Hind et al, 2023) and the odd stem of Vernonia missurica Raf. (see Hind & Langhorne, 2023), before the autumnal and early winter weather started to batter everything down—or perhaps the all too frequent deer may have been responsible.…”

1079. Symphyotrichum laeve (L.) Á. Löve & D. Löve: Compositae

“…This is now considered a synonym of S. novi-belgii-the generitype. Symphyotrichum contains just over 90 species (Nesom, 2000), largely North American (with 77 species), two widespread pantropical species, a few South American species (see Hind & Strange, 2018).…”

“…Somewhat late in the flowering season, Symphyotrichum laeve (L.) Á. Löve & D. Löve (Compositae: Astereae: Symphyotrichinae), the so‐called smooth aster or the glaucous Michaelmas daisy and the subject of this plate, with its often modest stature and bluish‐violet capitula, stands in somewhat stark contrast to a backdrop of the yellows of Solidago nemoralis Aiton (see Hind & Lambkin, 2023a), Coreopsis lanceolata L. (see Hind et al, 2023) and Rudbeckia hirta L. (see Hind & Lambkin, 2023b), the white Parthenium integrifolium L. (see Hind & King, 2023) (all in the Compositae), and the architectural whitish‐flowered Eryngium yuccifolium Michx (Umbelliferae) (see Rix & Lambkin, 2023).…”

Species Delimitation in the Symphyotrichum subulatum Group (Asteraceae) Reveals a New Species in Central Mexico

“…Comprising . 100 species of herbaceous annual or perennial plants, Symphyotrichum is one of the most diverse genera in the eastern US flora and extends across North America, South America, Mexico, the Caribbean, and eastern Eurasia (Everitt et al 2007; Hind and Strange 2018). Despite being the largest and most familiar genus within the subtribe Symphyotrichinae, Symphyotrichum remains the most problematic, with a complex taxonomic history including understudied but putatively widespread hybridization and polyploidy (Brouillet et al 2006; Vaezi and Brouillet 2009).…”
