Morphology of the Morelloid Clade of Solanum. A Most species are found in disturbed habitats in the wild (S.douglasii, Ochoterena et al. 979) B small “spinose” processes are common on herbaceous stems in many species of black nightshades (S.emulans, Nee 61357) C glandular hairs are present in some species of morelloids (S.pruinosum, Amith 30248) D small stellate flowers in lateral inflorescences that are developmentally terminal characterise the clade (S.emulans, Nee 61357) E orange-red fleshy berries of S.corymbosum in highly branched inflorescences (Särkinen et al. 4604B) F black fleshy berries of S.nigrum (Nijmegen accession A44750150) G stone cells (also known as sclerotic granules or brachysclerids, L side of photo) are found in the fruits of most species of the Morelloid Clade and are round in shape as compared to the tear-drop shaped or ellipsoid seeds (R side of photo) (the African species S.umalilaense Manoko, Nijmegen accession A24750133) H stone cells are easy to see in herbarium specimens of some taxa (e.g., S.sarrachoides, Blom 2s.n. BM001207745). Photos by S. Knapp, T. Särkinen, and G. van der Weerden (previously published in “PhytoKeys 106”).
