Confirming the identity of two enigmatic "spiny solanums" (Solanum subgenus Leptostemonum, Solanaceae) collected by Jean-Baptiste Leschenault in Java.

ABSTRACT: Taxonomic revision of the tropical Asian species of Solanum revealed two names, Solanum poka Dunal and Solanum graciliflorum Dunal, whose identities were uncertain and whose application has always been tentative. Material collected in Java at the beginning of the 19th century by Jean-Baptiste Leschenault de la Tour and used to describe these taxa has not been found, despite extensive searches in European herbaria. We here stabilise use of these names by comparing herbarium specimens and drawings of original material made by the artist Toussaint François Node-Véran. Detailed descriptions with synonymy, preliminary conservation assessments and specimen citations are provided for both species. Lectotypes are designated for all names (including synonyms) and epitypes designated for Solanum poka and Solanum graciliflorum to stabilise usage.

A new species of spiny Solanum (Solanaceae) from Peru.

Project description:A new species of Solanum is described from Peru. Solanum junctum S. Stern & M. Nee, sp nov. is a member of the Torva clade of the spiny solanums (Leptostemonum clade). The narrow corolla lobes and recurved prickles of Solanum junctum are similar to species in the Micracantha clade, but Solanum junctum differs in its branched inflorescences and upright green fruits. These characteristics are shared with other members the Torva clade; within this section Solanum junctum is morphologically most similar to Solanum subinerme and Solanum poinsettiifolium. Solanum subinerme has larger flowers, longer cauline prickles, and often has long straight prickles on the adaxial leaf surface that are lacking in Solanum junctum. Solanum poinsettiifolium has fewer spines, dense white tomentum on the abaxial leaf surfaces, stout unbranched inflorescences, and more extensive interpetalar corolla tissue than Solanum junctum.

Four new non-spiny Solanum (Solanaceae) species from South America.

Project description:Four new species of "non-spiny" Solanum from South America are described. Solanumlongifilamentum Särkinen & P.Gonzáles, sp. nov. (Morelloid clade) is widespread from Ecuador to Bolivia and is most similar to Solanummacrotonum Dunal from Central and northern South America. Solanumantisuyo Särkinen & S.Knapp, sp. nov. (Morelloid clade) is found on the eastern Andean slopes in Ecuador, Peru and Bolivia and is most similar to the widespread lower elevation species Solanumpolytrichostylum Bitter. Solanumarenicola Särkinen & P.Gonzáles, sp. nov. (Morelloid clade) is found in low elevation habitats on the eastern Andean slopes and in Amazonia of Peru and Bolivia and is most similar to the higher elevation species Solanumaloysiifolium Dunal of Bolivia and Argentina. Solanummariae Särkinen & S.Knapp, sp. nov. (Potato clade) is endemic to Cajamarca Department in Peru, and is most similar to the widespread Solanumcaripense Dunal. Complete descriptions, distributions and preliminary conservation assessments of all new species are given.

A revision of the Solanum elaeagnifolium clade (Elaeagnifolium clade; subgenus Leptostemonum, Solanaceae).

Project description:The Solanum elaeagnifolium clade (Elaeagnifolium clade) contains five species of small, often rhizomatous, shrubs from deserts and dry forests in North and South America. Members of the clade were previously classified in sections Leprophora, Nycterium and Lathyrocarpum, and were not thought to be closely related. The group is sister to the species-rich monophyletic Old World clade of spiny solanums. The species of the group have an amphitropical distribution, with three species in Mexico and the southwestern United States and three species in Argentina. Solanum elaeagnifolium occurs in both North and South America, and is a noxious invasive weed in dry areas worldwide. Members of the group are highly variable morphologically, and this variability has led to much synonymy, particularly in the widespread S. elaeagnifolium. We here review the taxonomic history, morphology, relationships and ecology of these species and provide keys for their identification, descriptions, full synonymy (including designations of lectotypes) and nomenclatural notes. Illustrations, distribution maps and preliminary conservation assessments are provided for all species.

From introduced American weed to Cape Verde Islands endemic: the case of Solanum rigidum Lam. (Solanaceae, Solanum subgenus Leptostemonum).

Project description:A Solanum species long considered an American introduction to the Cape Verde Islands off the west coast of Africa is identified as Solanum rigidum, a member of the Eggplant clade of Old World spiny solanums (Solanum subgenus Leptostemonum) and is probably endemic to the Cape Verde Islands. Collections of this species from the Caribbean are likely to have been introduced from the Cape Verde Islands on slave ships. We discuss the complex nomenclatural history of this plant and provide a detailed description, illustration and distribution map. The preliminary conservation status of Solanum rigidum is Least Concern, but needs to be reassessed in light of its endemic rather than introduced status.

On the identity and typification of Solanum brasilianum Dunal (Solanaceae).

Project description:Solanum brasilianum Dunal was described by Dunal in 1813 with reference only to an illustration in an 18th century work by Leonard Plukenet. The plate is difficult to interpret and no explicitly related specimens were available so the name Solanum brasilianum has long been regarded as "unresolved" and has never been used. Material matching the Plukenet plate was discovered in the herbarium of the University of Oxford (OXF) by Stephen Harris during his study of the English privateer William Dampier's Brazilian collection. The specimen is referable to a common Brazilian Solanum that is a member of the Torva clade, Solanum paniculatum L., making Solanum brasilianum Dunal a heterotypic synonym. We lectotypify Solanum brasilianum here, and designate an epitype using the Dampier material from OXF.

Two new South American species of Solanum section Crinitum (Solanaceae).

Project description:Two new species of Solanum section Crinitum are described here. Solanum falciforme Farruggia, sp. nov., closely resembles Solanum crinitum and Solanum lycocarpum, but differs by the presence of falcate trichomes on the young growth. It is endemic to the cerrado and adjacent woodlands of Distrito Federal, Bahia, Goiás and Minas Gerais, Brazil. The other species, Solanum pseudosycophanta Farruggia, sp.nov., has close affinities to Solanum sycophanta butdiffers from the latter in having prominent long-stalked stellate hairs along the stem, calyx, petiole and the adaxial surface of the leaf, in contrast to Solanum sycophanta which is glabrous or pubescent with sessile to short-stalked multangulate hairs. This species is narrowly distributed in tropical montane forests of northern Peru and southern Ecuador.

Two new non-spiny Solanum (Solanaceae) from the Gran Chaco Americano and a key for the herbaceous glandular-pubescent solanums from the region.

Project description:The Gran Chaco Americano is a major savanna woodland system in South America that harbours great plant and animal diversity. Two new herbaceous species of the Morelloid clade of Solanum (largely corresponding to the traditional Solanum section Solanum) are described here from the Bolivian Chaco. Both species are morphologically similar to a group of related species with glandular pubescence and enlarged, foliaceous calyces that includes Solanum atriplicifolium Gillies ex Nees, Solanum nitidibaccatum Bitter, Solanum physalifolium Rusby, Solanum sarrachoides Sendtn. and Solanum tweedianum Hook. Solanum woodii Särkinen & S.Knapp, sp. nov. is unusual in the Morelloid clade in having tapering anthers on short filaments, and is superficially similar to the unrelated Solanum anomalostemon S.Knapp & M.Nee from dry forests in Peru. Solanum michaelis Särkinen & S.Knapp, sp. nov. is distinct in its enlarged calyx with a short tube and long lobes that apparently reflex at fruit maturity. Both new taxa are illustrated, their conservation status assessed, and their distributions mapped. We also provide a key to the glandular-pubescent herbaceous Solanum species of the Chaco vegetation to aid in identification of these taxa.

Two new non-spiny Solanum species from the Bolivian Andes (Morelloid Clade).

Project description:Two new Bolivian species are described from the Morelloid clade of Solanum (section Solanum in the traditional sense). Solanumalliariifolium M.Nee & Särkinen, sp. nov. is found in montane forests between 1,900 and 3,200 m and is morphologically most similar to Solanumleptocaulon Van Heurck & Müll.Arg., also from montane forests in southern Peru and Bolivia. Solanumrhizomatum Särkinen & M.Nee, sp. nov. is found in seasonally dry forests and matorral vegetation in lower elevations between 1,300 and 2,900 m and is most similar to Solanumpygmaeum Cav., a species native to sub-tropical Argentina but introduced in subtropical and temperate areas worldwide.

A revision of the "African Non-Spiny" Clade of Solanum L. (Solanum sections Afrosolanum Bitter, Benderianum Bitter, Lemurisolanum Bitter, Lyciosolanum Bitter, Macronesiotes Bitter, and Quadrangulare Bitter: Solanaceae).

Project description:The African Non-Spiny (ANS) clade contains 14 species of mostly large canopy lianas or scandent shrubs confined to Madagascar (10) and continental Africa (4, with with one species reaching the southern Arabian peninsula). Members of the clade were previously classified in sections Afrosolanum Bitter, Benderianum Bitter, Lemurisolanum Bitter, Macronesiotes Bitter and Quadrangulare Bitter, and were throught to be related to a variety of New World groups. The group is an early-branching lineage of non-spiny solanums and characters shared with other vining New World solanums are homoplastic. The 14 species of the group occupy a wide range of habitats, from wet forests in western Africa to savanna and dry forests of southern Madagascar and dune habitats in South Africa. Many members of the group are highly variable morphologically, and habit can vary between shrub and canopy vine in a single locality. We here review the taxonomic history, morphology, potential relationships and ecology of these species; we provide keys for their identification, descriptions, full synonymy (including designations of lectotypes and neotypes) and nomenclatural notes. Illustrations, distribution maps and preliminary conservation assessments are provided for all species.
