Senecioneae is the largest tribe ofAsteraceae, comprised ofca. 150 genera and 3,000 species. Approximately one-third of its species are placed in Senecio, making it one of the largest genera of… Expand
Patterns and causes of incongruence between plastid and nuclear Senecioneae (Asteraceae) phylogenies.
- P. Pelser, A. Kennedy, +4 authors L. Watson
- Biology, Medicine
- American journal of botany
- 1 May 2010
One of the longstanding questions in phylogenetic systematics is how to address incongruence among phylogenies obtained from multiple markers and how to determine the causes. This study presents a… Expand

The number of Rafflesia species (Rafflesiaceae) reported for the Philippines has grown explosively from two before 2002 to ten or eleven presently. We present an overview of the current knowledge of… Expand
The evolution of pyrrolizidine alkaloid biosynthesis and diversity in the Senecioneae
Pyrrolizidine alkaloids are characteristic secondary metabolites of the Asteraceae and some other plant families. They are especially numerous and diverse in the tribe Senecioneae and form a powerful… Expand
