Inferences of biogeographical histories within subfamily Hyacinthoideae using S-DIVA and Bayesian binary MCMC analysis implemented in RASP (Reconstruct Ancestral State in Phylogenies).
Biogeographical analyses reveal that subfamily Hyacinthoideae has originated in sub-Saharan Africa, and indicates an early dispersal event to the Mediterranean region followed by a vicariance event, which resulted in Hyacintheae and Massonieae tribes.
Sagittanthera (Hyacinthaceae, Urgineoideae), a new buzz pollinated genus from the Eastern Cape Province of South Africa

This study shows that the current concept of M. echinata, including M. angustifolia and M. lanceolata as synonyms, includes two unpublished species which are here described as M. pseudoechinata andM.
Massonia inaequalis (Asparagaceae, Scilloideae), a distinct new species from South Africa
Asparagaceae subfamily Scilloideae, tribe Hyacintheae is alternatively regarded as Hyacinthoidae, a treatment the authors favour.
Systematic Position of Three Little Known and Frequently Misplaced Species of Hyacinthaceae from Madagascar
Supporting evidence is found that U. volubilis is not a member of the subfamily Urgineoideae but belongs to theSubfamily Ornithogaloideae with strong affinity to the Stellarioides/Albuca/Coilonox clade.
