“…The trichomes in both of the species described here are multangulate-stellate, however they differ from those illustrated in Roe (1968Roe ( , 1971 in that some of the three to five primary trichome rays often bear another set of two to three stellate rays, and those can also be rebranched ( Fig. 1A; Table 1).…”

“…The terminology used to describe the sympodial branching pattern of the species follows that of Child and Lester (1991) and Bohs (1994) and has been used previously in Lycianthes (Dean 2004, Dean et al 2017. Trichome terms are taken from Roe (1968Roe ( , 1971) and follow current usage in the Solanaceae (Sampaio et al 2014), although some current papers use the term multiangulate trichome rather than multangulate trichome (used by Roe and used here).…”

Two new species of Lycianthes (Capsiceae, Solanaceae) from Mexico and Guatemala

Two cloud forest species of Lycianthes are newly described: L. breedlovei from the state of Chiapas, Mexico and L. fredyclaudiae from the state of Baja Verapaz, Guatemala. Both species have orange-brown, multangulate-stellate trichomes in which the rays of the trichome are rebranched, white to pale lilac flowers (with darker violet-purple lobes in L. breedlovei), and unequal stamens. Morphologically, they resemble L. hortulana of Honduras, but both new species have previously been misidentified as L. cuchumatanensis. This article provides species descriptions, maps of geographic distributions, drawings of trichomes, and images of the flowers and specimens of the two new species, as well as a comparison chart of morphological characters used to separate L. breedlovei and L. fredyclaudiae from similar species.

Three new species of “non-spiny" Solanum are described from Peru and Ecuador, and a revised description for Solanum verecundum M. Nee is presented. Solanum kulliwaita S. Knapp, sp. nov. (Dulcamaroid clade) is endemic to the Department of Cuzco in southern Peru, and is most similar to the recently described Solanum sanchez-vegae S. Knapp of northern Peru. Solanum dillonii S. Knapp, sp. nov. (Brevantherum clade) is found in southern Ecuador and northern Peru in the Amotape-Huancabamba phytogeographic zone, and is morphologically similar to the widespread Solanum riparium Ruiz & Pav. Solanum oxapampense S. Knapp, sp. nov., (also of the Brevantherum clade) is endemic to the Oxapampa region (Department of Pasco) of central Peru, and is similar to and segregated from Solanum verecundum M. Nee of Peru and Ecuador. Complete descriptions, distributions and preliminary conservation assessments of all new species are given.

“…Solanum mauritianum Scopoli (Solanales: Solanaceae), commonly known as bugweed (South Africa), woolly nightshade (Australia and New Zealand) or tobacco bush (Australia), is a perennial tree native to South America, particularly northeastern Argentina, southern Brazil, Paraguay and Uruguay . Solanum mauritianum has become naturalized in Africa, Australasia, India and islands in the Atlantic, Indian and Pacific oceans, presumably via the Portuguese trade routes in the early 16th century . The tree has reached invasive status in several countries .…”

BACKGROUND The South American tree Solanum mauritianum Scopoli (Solanaceae) is a problematic invasive plant in numerous tropical, subtropical and temperate regions around the globe. Because conventional management approaches are not cost‐effective, biological control provides an alternative approach. Gargaphia decoris Drake (Tingidae) is currently used as a biological control agent in South Africa and New Zealand. Considering the importance of climate in the establishment and success of a biological control agent, this study used ecological niche models (ENM) to identify areas where S. mauritianum is a problematic invader and where suitable conditions exist for G. decoris. Additionally, the climate niche dynamics of G. decoris were investigated and ENMs projected worldwide for the year 2050 were built. RESULTS Our results indicate that most of the countries where S. mauritianum is problematic have suitable climatic conditions for G. decoris, and that the species can survive in climates with temperatures lower than those in its native range. For future climates, ENMs predict wider regions with favourable climatic conditions for G. decoris. CONCLUSION Considering the results of this study, the prospects of using G. decoris as a biological control agent are good under current and future climates. Introduction of this agent could be considered in affected countries where it has not been released. © 2019 Society of Chemical Industry
