Leptostelma maximum D. Don in Sweet, Brit. Fl. Gard., ser. 2, 1 [vol. 4 of whole work]: 38 (March 1830). Type: A native of Mexico; a plant of which was obtained by Mr Hunnemann, in the Autumn of 1827, from the Berlin Botanic Garden, for Robert Barclay, Esq. in whose collection it flowered last Autumn. ... Note: Teles et al. (2008) have suggested that the type may well be in B, which if true it is unlikely to be extant. It is more likely that if a specimen was made it would have been in either David Dons collection (which is supposed to be in BM) or in Sweets own collection which is largely in CGE. However, two other points are worth considering. Firstly, Robert Barclay, who died in October 1830, had an extensive garden and, bearing in mind the suggested date for the flowering of this plant (c. 1829) it is likely that Don described it from that material. Secondly, there is a specimen in K (ex herb. Benthamianum of two flowering branches and one large leaf) which has Erigeron maximum/Hort Soc. Hort. Lond 1830/Leptostelma gigantea/D. Don MSS! written in Benthams hand on the sheet. This suggests that Bentham was aware of Dons manuscript, although it appears that Don changed the name. Since there is a suggestion that the plant used for drawing the plate in the British Flower Garden was a perennial it is highly likely that it is the same stock as Barclays.

Note: Very strangely, Solbrig (1962: 12) cited Gardner 4923Ž'' as the basis for Erigeron schuchtii var. minor Baker, having already cited this collection as the type of Erigeron scaberrimum Gardner. Baker (1882: 28) mentioned this Gardner collection agains the typical species, not this variety and, incidentally, Baker most certainly did not cite this species (just Erigeron schuchii Schultz Bip. but under the species synonymy), nor this variety under it; Baker actually described the variety as new. Schultz Bipontinus name, a nom. nud., was provided as E. schchtii in Linnaea 22: 571 (1849), referring to Regnell I. 202.

Note: This species was described too late to include in the transfers recently made by Hind (2008)[2009], but would, following generic concepts employed by me, clearly be included in Vernonia.
