Description

Solanum lesteri distribution Map note

Solanum lesteri (lesteri, in honor of Richard N. Lester, the British botanist who first collected the species) is a woodland plant, native to Mexico, where is is known only from Oaxaca.  Plants range from just over a foot to about 4.5 feet tall.  Fruits long and severely pointed.  Leaves are densely covered with glandular hairs.

This species can survive frosts down to 27.5 degrees F (-2.5 C) (Li 1977).  Vega (1995) found that this species is less frost tolerant than domesticated potato.

Cultivation

I have found seeds of this species easy to germinate using the standard conditions for S. tuberosum.  Seedlings are large and robust compared to most wild species and domesticated varieties.

Crosses with other species

Watanabe (1991) found that 6.3% (which was only 1 plant) of varieties of this species produced 2n pollen and Jackson (1999) found 2-13%, which would be effectively tetraploid and probably 2EBN.
