The flowers of the 2013 collection were all male-sterile, it seems from photos. To do: Look back at preserved material from 1999 collection and see if flowers were male-sterile (comment of 13 July 2013).

This species is very hard to find. It grows in remant patches of native vegetation, and even when you find such a patch you can look for this species and not see it. In other words, even eyes that are highly trained to spot the genus Jaltomata can, at times, not detect this species!

Shrub; leaf blades to 2.7 cm long; inflorescence 6–10 flowered; corolla whitish, crateriform, with 10 green maculae in throat and a purple ring fading in intensity proximal to distal, 5 – 7 mm in diameter, 10-lobed, the lobes and lobules alternating; the stamens very short, included, purple where the filaments meet their expanded bases.
