Taxonomy

Former subspecies

In the past this plant was variously considered a variety of other Solanum species. It was included in Solanum glutinosum as var. irazuense by Kuntze (note that there was also a S. irazuense, which is the same as Solanum pubigerum. It was included in Solanum corymbosum of von Jacquin (a valid species), and in S. hernandesii (which is currently Solanum ferrugineum) as var. corymbosum by Dunal – not to be confused with the S. corymbosum of Wight based on Nees (which is the same as the nomen nudum S. vagum of B. Heyne, based on N. Wallich). Like many nightshade species, it was also included in Solanum torvum, in its case by Otto Sendtner as var. schiedeanum.[2]

Former synonyms

There are also a number of now-invalid names where the orangeberry nightshade was considered a distinct species. Many of these are also homonyms of other Solanum taxa:[2]

• Solanum amictum Dunal

S. amictum var. fructipendulum is S. rudepannum.

• Solanum bifidum Sessé & Moc. (non Dunal in DC.: preoccupied)

The S. bifidum described by Dunal in de Candolle is S. lepidotum. That described by de Conceição Vellozo from Dunal in DC. is S. subumbellatum.

• Solanum canescens Pav. ex Dunal (non Blume: preoccupied)

S. canescens as described by Blume is an undetermined species. The S. canescens of L.C. Richard based on Dunal in de Candolle is the S. asperum of L.C. Richard. That described by Kitaibel is S. villosum of Philip Miller.

• Solanum cinerascens Pav. ex Dunal
• Solanum cymosum Ortega

The S. cymosum described by Banks from Dunal in de Candolle is S. viridifolium. The one described by Ruiz & Pavón Jiménez is S. corymbosum of von Jacquin.

• Solanum densiflorum M.Martens & Galeotti

As described by Otto Sendtner in von Martius, S. densiflorum refers to S. piluliferum. As described by Dunal in de Candolle, it refers to the indeterminable S. athroanthum.

• Solanum floccosum M.Martens & Galeotti (non Zipp. ex Span.: preoccupied)

S. floccosum Zipp. ex Span. is an undetermined species. As described by Dunal in de Candolle it refers to S. pachimatium.

• Solanum hartwegii Benth.
• Solanum inaequale Hornem.

S. inaequale of de Conceição Vellozo is S. pseudoquina. The one described by C. Presl is S. lanceifolium of von Jacquin.

• Solanum lambertii Dunal
• Solanum lanceolatum var. sinuatum Dunal
• Solanum leiboldianum Dunal
• Solanum macrophyllum Hort. ex Dunal
• Solanum mexicanum Dunal
• Solanum mexicanum var. albiflorum Dunal

The S. mexicanum described by Willdenow from J.J. Roemer & J.A. Schultes is S. pubigerum. The one described by Sessé & Mociño is S. bulbocastanum.

• Solanum schiedeanum Schltdl.
• Solanum vellereum Schltdl.

Other nomenclature

The taxon S. lanceolatum had also been used for other Solanum species in error. As used by Ruiz & Pavón Jiménez, it refers to Solanum ruizii. The S. lanceolatum of Berthault is Solanum cardiophyllum as described by John Lindley.[2]

Cultivation — invasive species

Solanum lanceolatum is cultivated as an ornamental plant.

It was introduced to California as a garden plant, but has naturalized and ranked a noxious weed there.[3]
