| Olmstead et al. (1999) presented phylogenetic analyses of the Solanaceae based on restriction site variation of the entire chloroplast genome (Olmstead & Palmer, 1992) and DNA sequences of two genes, rbcL and ndhF (Olmstead et al. 1992, 1994; Olmstead & Sweere, 1994). These analyses contained one species of Nolana, and Nolana was deeply nested within the Solanaceae-Solanoideae in a clade with Lycium and Grabowskia (Lycieae). Johnston (1936), on morphological evidence, already had suggested that Nolana shared relationships with both Lycium and Grabowskia. |

 Grabowskia boerhaviifolia is an autodisjunction from the mainland of northern Peru. |
 Grabowskia boerhaviifolia usually inhabits arid and near shore environments. and its leaves are laminar, elliptic-ovate and succulent. |
