Sinningia sulphurea

[Dennis Kramb]

Formerly known as Sinningia sp. 'Bahia' for the region of Brazil in which it was discovered, the official name Sinningia sulphurea was published a couple months ago.  Of the 75-ish species in the genus it's one of the few yellow-flowered ones.

I don't have the other species that is named in this article, but some friends here in the USA are growing it.
