Almost 80% of the approved drugs and 67% of the clinical-trial drugs concentrated in 17 and 30 drug-prolific families, respectively, including Fabid and Malvid groups of the Rosidae subclass, the Lamiid and Campanulid groups of the Asterid
subclass, and the Ranunculales order .
A morphological matrix (Table 6) based on the asterid
taxa used by Bremer et al.

flowering plants shows early cretaceous diversification," Systematic Biology, vol.
Plantains (Plantago L.) are widely distributed herbs and shrubs from the asterid
CPT is produced by several plant species belonging to the Asterid

(Coffea canephora and Solanum Sp.) and rosid (Vitis vinifera) clades" BMC Genomics, vol.
The fact that nearly all other species of Austromirini are found on dicot angiosperms (mostly rosid and asterid
flowering plants) suggests that grass affiliation is likely a host switching event.

At least some families even in the most recently derived of the plant clades used in this analysis date to this time, such as, Urticaceae (a member of Rosid 1 in Chase et al., 1993): 90 M.Y.B.P., Rutaceae (Rosid 2): 52 M.Y.B.P., Apiaceae (Asterid
2): 52 M.Y.B.P., Apocynaceae (Asterid
1): 60 M.Y.B.P.
Such divergent clades might have been lost with the evolution of Arabidopsis lineage or gained along with the development o[micro]lineages of rosid and asterid
. The subgroups which are closer show that the genes have originated from the same duplication event.
Both orbicule presence and absence is recorded from the earliest diverging flowering plants up to most recent diversified asterid
However, recently, following the Angiosperm Phylogeny Group III classification, Larsson (2007) showed that the distribution of CPT in plants is restricted to the Asterid
group members only.
