A student from the University of Oregon, at present collecting in the park, expects to obtain fully five hundred, and possibly seven hundred, species. Seven species were reported as being from Crater Lake only, but a report from the national herbarium invalidates one determination and two others are reported from one station in northern California, while another is found in this region, but outside the park boundaries. The remaining three are Colomium mazama, Cov., Arinaria pumicola, Cov. and Leib, and Eucepahlus covellii, Greene.
