Autorité : La plupart des bases de données sont ambigues sur l'autorité de ce nom "Schomb. ex Benth.", "R.H.Schomb. ex Benth." ou "M.R.Schomb. ex Benth."? D'après Molino et al. (2022): "In their recent revision of Paloue, Redden et al. (2018) cite the basionym of P. princeps, Elizabetha princeps with the authorship “M.R.Schomb. ex Benth.”, and give the type “Guyana. 1839 (fl., fr.). R. Schomburgk s.n. (holotype: K!; isotype: F!)”. However, the original material collected in 1839 and reported by Hooker in 1840 was collected by Robert (Hermann) Schomburgk, not his younger brother (Moritz) Richard who first arrived in Guyana in 1841. Further, the specimen mentioned as isotype by Redden et al. (2018) (F, V0057797F) is a fragment of a lost B specimen (photo F neg. N° 1560). If this specimen was collected by Richard Schomburgk, as the label seems to indicate, then it cannot be part of the original material."

(LT: K000264886) [ex hb. Benth.; "Holotype, Elizabetha princeps Schomb. ex Benth., det. R.S. Cowan, 10/1975"; désigné comme lectotype par R.S. Cowan in Fl. Guianas, Ser. A, 7: 29. 1989 (première étape), puis par Molino et al. in Adansonia, 44(26): 533. 13/12/2022 (seconde étape)]; ILT: K000264887 [ex hb. Benth.], K000264888 [ex hb. Hook.]).
Matériel non original !:
Guyana, mont Roraima, 1841, Schomburgk s.n. [probablement R.H. Schomburgk II.210 = M.R. Schomburgk 133] (B détruit [photo: F neg. 1560; fragment: V0057797F).

If this specimen was collected by Richard Schomburgk, as the label seems to indicate, then it cannot be part of the original material. Among the three original specimens of Elizabetha princeps R.H.Schomb. ex Benth. at K, two are in Herbarium Benthamianum. One of them (K000264886) has a label “Holotype, Elizabetha princeps Schomb. ex Benth., det. R.S. Cowan, 10/1975” and is here designated as lectotype. The other two (K000264887, in Herbarium Benthamianum, and K000264888, in Herbarium Hookerianum) are isolectotypes."
