I believe this plant may have been incorrectly moved to Strobilanthes,
Purple Waffle Plant (Hemigraphis Snow White)
or that another plant should be moved also ('Exotica'):
Purple Waffle Plant (Hemigraphis 'Exotica')

Tracing SW's history, it's a sport of the plant that Engelmann's (Exotic Angel / Costa Farms) has always sold as H. alternata, the "purple waffle plant," Hemigraphis alternata 'Exotica.'
The patent: https://www.google.com/patents...
Their catalog page showing that 3 of the plants are cultivars of the same species, and that they also sell H. repanda:

Their other cultivar seen on the page is sold as 'Belgian Waffle' and also has a patent:

EA/CF is not known for being a resource for plant names, so alternata may or may not be the correct species name for these 3 cultivars ('Exotica', 'Snow White' and 'Belgian Waffle',) but they are the same plant, whatever its' name.

Thanks for pointing out the parentage connection between these three plants. Purple Waffle Plant (Hemigraphis 'Exotica') does appear to be a cultivar of unknown species by most sources I've found. Since both Snow White and Belgian Waffle (just added) are sports of 'Exotica' I've edited the entries to show Hemigraphis alternata as an also sold as name. If evidence surfaces indicating 'Exotica' is a species H. alternata plant the parentage field data will give us a trail to correct all three entries.
