@ARTICLE{TreeBASE2Ref14928, author = {Philip D. Cantino and Steven J. Wagstaff and Richard G. Olmstead}, title = {Caryopteris (Lamiaceae) and the conflict between phylogenetic and pragmatic considerations in botanical nomenclature.}, year = {1998}, keywords = {}, doi = {}, url = {http://www.jstor.org/stable/2419511}, pmid = {}, journal = {Systematic Botany}, volume = {23}, number = {3}, pages = {369--386}, abstract = {The delimitation of Caryopteris (Lamiaceae) exemplifies the conflict between the representation of monophyletic groups and pragmatic concerns in Linnaean classification. Cladistic analyses of nonmolecular (mainly morphological) data and chloroplast DNA (rbcL and ndhF) sequences were performed to test the monophyly of the eastern Asian genus Caryopteris. The results corroborate earlier studies indicating that Caryopteris is either para- or polyphyletic. If paraphyletic, other genera whose sister groups lie within the currently accepted limits of Caryopteris include Trichostema, Rubiteucris, and probably Ajuga, Schnabelia, and Amethystea. Because phylogenetic resolution is too poor to refer all of the species of Caryopteris to well supported clades, a choice must be made between recognizing a paraphyletic genus or several monotypic ones, three of which would comprise morphologically quite similar species. A compromise solution is adopted in which three new genera are described (Pseudocaryopteris, Discretitheca, and Tripora), the latter two monotypic, and four species of Caryopteris are transferred to other genera, one of which may not be monophyletic. Nine new combinations are provided: Discretitheca nepalensis, Pseudocaryopteris bicolor, Pseudocaryopteris foetida, Pseudocaryopteris paniculata, Rubiteucris siccanea, Schnabelia aureoglandulosa, Schnabelia nepetifolia, Schnabelia terniflora, and Tripora divaricata. For comparative purposes, an alternative classification is provided that employs de Queiroz and Gauthier?s phylogenetic system of nomenclature. Using this system, no new names are required, and all supraspecific taxa are both monophyletic and easily recognizable.} }
