A taxonomic revision of Schlechterella (Periplocoideae, Apocynaceae)

Generic delimitations in tuberous Periplocoideae (Apocynaceae) from Africa and Madagascar.

BACKGROUND AND AIMS The number of genera included in Apocynaceae subfamily Periplocoideae is a matter of debate. DNA sequences are used here as an independent dataset to clarify generic relationships and classification of the tuberous periplocoid genera and to address the question of the phylogenetic interpretation of pollinia formation in Schlechterella. METHODS Representatives of nearly all...

TAXONOMIC REVISION OF THE CYPERUS SUBGENUS CYPERUS IN IRAN

The genus Cyperus belongs to tribe Cypereae, subfamily Cyperoideae and family Cyperaceae that is the largest genus in this family after Carex. The classification of genus Cyperus is still unsettled because of morphological variations and therefore, makes determination of subgenera boundaries and species difficult. In Flora Iranica (KUKKONEN 1998) this genus was divided to six subgenera. In this...

Vessel grouping patterns in subfamilies Apocynoideae and Periplocoideae confirm phylogenetic value of wood structure within Apocynaceae.

This study contributes to our understanding of the phylogenetic significance and major evolutionary trends in the wood of the dogbane family (Apocynaceae), one of the largest and economically most important angiosperm families. Based on LM and SEM observations of 56 Apocynoideae species-representing all currently recognized tribes-and eight Periplocoideae, we found striking differences in vesse...
