Which genus, Menispermum or Solenopsis, has a name most similar to that of the family to which it belongs?
Menispermum Menispermum (moonseed) is a small genus of deciduous climbing woody vines in the moonseed family (Menispermaceae). Plants in this genus have small dioecious flowers, and clusters of small grape-like drupes. The name, moonseed, comes from the shape of the seed, which resembles a crescent moon. The word "Menispermum" is derived from the Greek words "mene", meaning moon, and "sperma" meaning seed. The common name moonseed is also applied to some other species in the related genus "Cocculus".
Mesangiospermae Mesangiospermae (core angiosperms) is a group of flowering plants (angiosperms), informally called "mesangiosperms". They are one of two main clades of angiosperms. It is a name created under the rules of the "PhyloCode" system of phylogenetic nomenclature. There are about 350,000 species of mesangiosperms. The mesangiosperms contain about 99.95% of the flowering plants, assuming that there are about 175 species not in this group and about 350,000 that are. While such a clade with a similar circumscription exists in the APG III system, it was not given a name.
