A Phylogenetic Study Of Arecaceae Based On Seedling Morphological And Anatomical Data, Flor M. Henderson, Dennis W. Stevenson
Aliso: A Journal of Systematic and Floristic Botany
A morphological and anatomical survey was carried out of seedlings of 62 taxa of palms representing all major groups. The data were analyzed using cladistic parsimony analysis. Seedling data were analyzed independently and combined with adult morphological data. Outgroup selection was made within the family using the calamoids and Nypa fruticans; outside the family, the monocot family Dasypogonaceae were used. The analysis with the calamoids and Nypa fruticans as outgroups resolved some of the major groups. The combined analysis, using both seedling and adult data and Dasypogonaceae as the outgroup, provided better resolution. Most of the major groups were …

a whole, strongly supported the mostly African tribe Amaryllideae as sister to the rest of the family, and resolved geographically-based monophyletic groups, but failed to resolve the relationships among several basal lineages in the family (the African Haemantheae and Cyrtantheae, the Australasian Calostemmateae, and the American and Eurasian sister clades). We present analysis of plastid ndhF sequences that fully resolved the major clades of the family. The baccate-fruited Haemantheae and Calostemmateae are sister tribes, and the African endemic Cyrtantheae is sister to them both. This clade is sister to an American/Eurasian clade. We also present preliminary nuclear ribosomal ITS …
