Hi all, A web search turned up the web site http://www.sysbot.org/ and an abstract of a publication Systematic Botany: Vol. 25, No. 4, pp. 708–726 (2000) "Phylogeny of the American Amaryllidaceae based on nrDNA ITS sequences" Alan W. Meerow, Charles L. Guy, Qin-Bao Li, and Si-Lin Yang Which I can only read as the abstract, since I don't subscribe to that journal. Worsleya is not mentioned in the abstract. Alan does note in the abstract that "Within the hippeastroid clade, the tribe Griffineae is resolved as sister to the rest of Hippeastreae. " which suggests that Hippeastrum is not an acceptable genus name for what we refer to as Worsleya rayneri or procerum. Other publications from Alan have put Worsleya and Griffinia in the tribe Griffineae, as far as I can recall at the moment. See the link at the bottom of the web page http://shieldsgardens.com/amaryllids/… Based on the DNA work, it appears that there is no way this species can be included in the genus Hippeastrum. We can safely use either Worsleya rayneri or Worsleya procerum to refer to this plant without fear of being misunderstood.
