Taxonomie : D'après Luer (Monogr. Syst. Bot. Missouri Bot. Gard., 61: 180-181. 12/1996) synonyme de
Lepanthes wageneri Rchb.f. 1855, mais il ajoute: "The vegetative form described as
L. dalstroemii is considerably larger with elliptical leaves borne by longer ramicauls." Néanmoins Luer (Luer, Monogr. Syst. Bot. Missouri Bot. Gard., 123:
217. 07/12/2012, voir
ici) se ravise ultérieurement: "
Lepanthes dalstroemii Luer was reduced to synonymy as a vegetatively larger variant of
L. wageneri (Luer 1996b). Re-examination of these two taxa shows discrete differences that support maintaining both species.
Lepanthes dalstroemii is very similar to
L. wageneri, but differs with longer, narrowly elliptical leaves borne by longer ramicauls; flowers with petals oblong with a small marginal angle between the lobes, rather than usually broadly oblong without a marginal angle; and a lip with blades with margins irregular rather than minutely pubescent, and an appendix ligulate rather than triangular."
