, S. quitoense is a part of the leptostemonum clade
Clade
A clade is a group consisting of a species and all its descendants. In the terms of biological systematics, a clade is a single "branch" on the "tree of life". The idea that such a "natural group" of organisms should be grouped together and given a taxonomic name is central to biological...

. Within this clade, S. quitoense belongs to the Lasiocarpa clade. Other species within this clade include: S. candidum, S. hyporhodium, S. lasiocarpum, S. felinum, S. psudolulo, S. repandum and S. vestissimum.

Other plants bear morphological similarity to S. quitoense, but they may or may not be closely related. Some of these plants are: S. hirtum, S. myiacanthum, S. pectinatum, S. sessiliflorum and, S. verrogeneum. Many of these plants, related or not, can be confused with S. quitoense. Furthermore, Solanum quitoenses physical traits vary from plant to plant, making identification challenging: at least three varietals (with spines, without spines, or a third variety known as baquicha, which features red-ripening fruits and smooth leaves) are known to occur. One characteristic that is unique to S. quitoense is the ring of green flesh within the ripe fruit.The only related fruit to have green flesh is the cultivated variant of Solanum lasiocarpum
Solanum lasiocarpum
Solanum lasiocarpum, otherwise known as Indian nightshade, is a plant that produces edible fruit. Its flowers are white and its fruits are pale yellow. S. lasiocarpum is native to temperate Asia, tropical Asia and the pacific....

Agriculture

The naranjilla has been proposed as a new flavouring for the global food industry, but it fares poorly in large-scale cultivation, presenting an obstacle to its wider use. Its fruit, like tomatoes, is easily damaged when ripe, so is usually harvested unripe. The fruits are found at markets. It is common for locals to make beverages by adding sugar and water to the freshly squeezed fruits. Locals will also add salt to the fresh fruit, cut it into pieces, and eat it.

. The ripe fruit can be attacked by fungus fairly easily, so it is often picked unripe to avoid rotting.

Hybrids are an increasingly popular solution to the nematode pest problem. Solanum quitoense has been hybridized with other plants, most commonly with S. sessiliflorum
Solanum sessiliflorum
Solanum sessiliflorum or Cocona is a tropical shrub belonging to the Solanaceae family. The cocona plant has sturdy branches and huge, serrate and hairy leaves. Cocona closely resembles a number of close relatives, including naranjilla and pseudolulo. It can be distinguished from those plants by...
