Description
This subfamily includes several genera, including small bushes reaching a meter in height ( Cneorum ), creeping and clinging plants ( Harisonia ) and small trees ( Bottegoa , Cedrelopsis and Ptaeroxylon ) [3] .
Evolution and phylogenesis
The subfamily Spathelioideae is the first detached taxon within the root family and can be described as a sister taxon in relation to Rutaceae sensu stricto [3] . According to reports, Spathelioideae appeared on the African continent at the end of the Cretaceous , followed by dispersion towards the Mediterranean , Madagascar and South Asia . The appearance of Spathelioideae in South America is associated with a period when the distance between this continent and Africa was relatively small (end of the Cretaceous) [4] . A study aimed at identifying synapomorphies for this taxon indicates that the common ancestor of Spathelioideae probably had leaves with secretory cavities and oil cells and flowers showing haploemonia [5] .
Classification
Under the family includes 6-7 births: [6]
- Bottegoa Chiov.
- Cedrelopsis Baill.
- Cneorum L.
- Dictyoloma A.Juss.
- Harrisonia r.Br. ex A.Juss.
- Ptaeroxylon Eckl. & Zeyh.
- Spathelia L.
The genus Dictyoloma is sometimes allocated to a separate subfamily Dictyolomatoideae .
