There are 2 spp. of Ismene subg. Pseudostenomesson, I. vargasii and I. morrisonii, which seem to differ largely on the basis of tube length. These are very high elevation green-flowered taxa with flowers that resemble a Clinanthus sp. (formerly Stenomesson in part). For a review see: Meerow, A. W., C. L. Guy, Q-B. Li, and J. R.
