Holotype
[GH]. Isotype(s)
[BISH?, GH, P [2 sheets]].
Note: Additional syntype: Remy 595, Ni`ihau. Koutnik made the Ni`ihau collection the lectotype of E. celastroides. Although Boissier did not cite numbers for the Remy collections, it is presumed that they are both number 595. The BISH sheet has neither locality nor number on it, so it cannot be determined whether it is an isolectotype of E. celastroides or an isotype of E. celastroides var. humbertii, if either (RKS, 8/95).
