“…Nutrient‐acquisition strategies are likely to vary among the approximately 280 lupine species worldwide. The unifoliate lupines in southeastern United States show phylogenetic affinity with the Old World lupines (Drummond, 2008; Eastwood et al, 2008), and several of these produce cluster roots and grow on dunal and/or open sandy, relatively infertile soils (Isely, 1986) (Fig. 5).…”

Lupines (Lupinus species; Fabaceae) are an ancient crop with great potential to be developed further for high-protein feed and food, cover crops, and phytoremediation. Being legumes, they are capable of symbiotically fixing atmospheric nitrogen. However, Lupinus species appear to be nonmycorrhizal or weakly mycorrhizal at most; instead some produce cluster roots, which release vast amounts of phosphate-mobilizing carboxylates (inorganic anions). Other lupines produce cluster-like roots, which function in a similar manner, and some release large amounts of carboxylates without specialized roots. These traits associated with nutrient acquisition make lupines ideally suited for either impoverished soils or soils with large amounts of phosphorus that is poorly available for most plants, e.g., acidic or alkaline soils. Here we explore how common the nonmycorrhizal phosphorus-acquisition strategy based on exudation of carboxylates is in the genus Lupinus, concluding it is very likely more widespread than generally acknowledged. This trait may partly account for the role of lupines as pioneers or invasive species, but also makes them suitable crop plants while we reach "peak phosphorus".

“…In North America the collections of drift disseminules on Floridia shores do not include Vigna. Most probably this is because both V. luteola and V. marina are native to this region (Isely, 1986). An origin in Africa is possible but unlikely.…”

“…This G. erecta specimen was otherwise annotated only by Anita F. Cholewa in 1986, erroneously as a probable isotype of G. brachypoda . When Isely (1986) mentioned that G. brachypoda could be a “freak form” of G. erecta , he also stated that there were “two Chapman sheets [of G. brachypoda ] at NY” and that G. brachypoda had pedunculate inflorescences, unlike this G. erecta specimen. Ward and Craighead (1990) speculated G. brachypoda was “probably an aberrant form” of G. erecta , and later Ward and Hall (2004) also stated that G. brachypoda was “based upon two A.W.…”

“…However, the descriptions of a decumbent (Vail 1895, Small 1903, Small 1933), ascending or sprawling (Isely 1986), procumbent (Nesom 2015), or prostrate habit (Nesom 2017) for G. brachypoda appear to be based on speculation from specimens and not field observations. While it was conjectured that it was impossible for G. brachypoda to be erect because its type specimens had stems to 37 cm long (Nesom 2017), another collection identified as G. brachypoda ( Anderson 15642 [FSU, GA]) with stems well over 40 cm long described on its label “robust, erect plants with limited twining” and was noted to be very similar to the type specimens of G. brachypoda (Franck 2017a, Nesom 2017).…”

Typifications for Galactia purshii and G. volubilis (Fabaceae)

The pervasive difficulties encountered with studying Galactia in the eastern USA necessitate additional typifications to stabilize the taxonomy. Galactia purshii is lectotypified here as the earliest available but overlooked name for a fairly common species of the Atlantic Coast and peninsular Florida. Galactia volubilis is epitypified here since the characterization of the species has been limited by its lectotype being an illustration. A lectotype is designated for Galactia pilosa var. angustifolia, a form with narrow leaves here considered synonymous with G. volubilis.
