Solanum nelsonii^[1] (often misspelled Solanum nelsoni), common names pōpolo^[2] and Nelson's horsenettle,^[3] is an annual to perennial plant in the Solanaceae family, part of the Solanum or nightshade genus. This poisonous plant is endemic to the Pacific Islands. It grows low to the ground in sandy soil.

Solanum nelsonii was listed as an endangered species by the U.S. Fish and Wildlife Service on September 30, 2016.^[4]

Nelson's horsenettle was first described by Michel Félix Dunal. The scientific name Solanum nelsonii has also – invalidly – been given to two other species of nightshade:

S. nelsonii of Zipp. based on Span. is the S. violaceum described by Ortega.
S. nelsonii of Correll is S. oxycarpum.

Several varieties of Nelson's Horsenettle have been described, but they are not usually considered valid anymore:

Solanum nelsonii var. acuminatum F.Br. in Christophersen & Caum

Not to be confused with S. acuminatum as described by Ruiz & Pavón Jiménez.

Solanum nelsonii var. caumii F.Br. In Christophersen & Caum
Solanum nelsonii var. intermedium F.Br. in Christophersen & Caum

Not to be confused with S. intermedium as described by Otto Sendtner in C.F.P. von Martius.

Solanum nelsonii var. thomasiifolium Seem.^[5]

Not to be confused with S. thomasiifolium.
