摘要:

An evaluation of the limits and infra‐generic taxonomy of the genusBoykiniaand its allies is presented. In the past,Boykiniahas been split into the following segregate genera:BoykiniaandTelesonix(from North America) andNeoboykiniaandPeltoboykinia(from Japan). The situation is complicated by other closely related genera, the limits of which also need clarification. Narrowly defined, they compriseSuksdorfia, Hemieva, Bolandra, SullivantiaandJepsonia(all from North America) andHieronymusia(from South America). This monograph draws on a variety of sources for information, including a morphological comparison of all taxa, using a wide range of both living and herbarium material, and observations on leaf anatomy, trichomes, pollen grains and seeds; reference is also made to our previously published work on flavonoids, chromosome numbers and breeding relationships. General ecological observations were made during field work in western North America. The results of these investigations confirm that the genera form a closely related group. Much of the evidence combines to suggest the following conclusions.Boykiniaincludes nine species in three sections: sectionBoykinia(B.aconitifolia, B.intermedia, B.lycoctonifolia, B.major, B.occidentalisandB. rotundifolia), sectionRenifolium (B. ruhardsonii)and sectionTelesonix (B. jamesiiandB. heucheriformis). Peltoboykinia (P. tellimoidesandP. watanabei) is recognized as a distinct genus allied to bothSaxifragaandBoykinia. Suksdorfia, expanded to includeHemievaandHieronymusia, has three species:S. violacea, S. alchemilloidesandS. ranunculifolia. Bolandrais very closely related toSuksdorfiabut is retained as a separate genus containing two species,B. californicaandB, oregana. SullivantiaandJepsoniaare accepted as genera related to, but distinct from,Boykini
