This species is another of the Sinningias with an interesting growth habit. The stems frequently have just one leaf, and bloom directly from the tuber — sometimes in the absence of any foliage.
This species has been confused with S. defoliata, even though they are not closely related. The resemblance in habit is due to evolutionary convergence.
This species has a tuber with “fingers” — extensions from which the stems grow.
