Dunal (1852) maintained as separate the genera Lycopersicon Mill. and Cyphomandra Sendtn., both now subsumed in a monophyletic Solanum (see Bohs 2005; Peralta et al. 2008).

Abstract. Aerosol particles are essential constituents of the Earth's atmosphere, impacting the earth radiation balance directly by scattering and absorbing solar radiation, and indirectly by acting as cloud condensation nuclei. In contrast to most greenhouse gases, aerosol particles have short atmospheric residence times, resulting in a highly heterogeneous distribution in space and time.
