My PhD project aims to resolve taxonomic relationships in East African members of the genus Kalanchoe Adans., a genus of succulent and herbaceous shrubs native to Africa, Madagascar, Arabia as well as Brazil and tropical Asia. I will examine species and infraspecific concepts in two species complexes viz. Kalanchoe lateritia and Kalanchoe nyikae, evaluate utility of species of Kalanchoe in relation to phylogeny, and establish the conservation status of the genus Kalanchoe in Kenya, using an integrated molecular methods and morphological trait-based analysis.
