The classification of the generic segregates of Phrygilanthus (= Notanthera) of the Loranthaceae

  • B. A. Barlow
  • D. Wiens


The taxonomic composition ofPhrygilanthus has long been a source of confusion. Until recently the genus was considered to be distributed from Mexico, Central and South America, to Australia, New Guinea, and the Philippines. Analyses of floral morphology, inflorescence structure, life form, fruit type, and especially chromosome numbers indicate thatPhrygilanthus, as classically circumscribed, is a highly heterogeneous and artificial assemblage containing elements now referable to the following ten genera:Cecarria, Desmaria, Gaiadendron, Ligaria, Muellerina, Notanthera, Psittacanthus, Struthanthus, Tripodanthus, andTristerix. Phrygilanthus itself is nomenclaturally illegitimate and must be replaced by Notanthera. A synopsis of the genera segregated from thePhrygilanthus group is included. A key to the New World genera of Loranthaceae is also appended as well as a nomenclator indicating the present generic status of taxa at one time or another assigned toPhrygilanthus. One genus,Cecarria, is described as new; five new combinations are made:Cecarria obtusifolia (Merr.) Barlow,Psittacanthus palmeri (Wats.) Barlow & Wiens,Struthanthus panamensis (Rizzini) Barlow & Wiens,Tristerix aphyllus (DC.) Barlow & Wiens, andTristerix grandiflorus (Ruiz & Pavon) Barlow & Wiens.
