Kegeliella, which it resembles vegetatively. Same size. Same thin textured plicate leaves, green on the upper surface and purple below. So I was startled in December to see five erect spikes with extraordinary flowers. Notice the lip in the 12 o'clock position; and the dark downy hairs on the spike and pedicels. (Sorry about the grainy blue-grey images. Did I mention that we've had 16 weekends in a row of rain?)
It first appeared in Europe in 1897 when Friedrich Carl Lehmann (19th century Prussian mining engineer, amateur naturalist and plant collector. More about his fascinating life here.) posted plants, drawings and a herbarium specimen to England. The original Latin name, Sievekingia shepheardii, was published with a description by R.A. Rolfe (distinguished botanist at the Kew herbarium and founder of the Orchid Review) in 1915. Soterosanthus is a monotypic genus--just one species.
