66 Nov. 8 (Sunday To Andover, N.J. and Killatinimes beyond Stillwater with Edwards. At White Pond, Andover: Pellaea glabella, Asplenium cryptolepis, Eleocharis rostellata, Rynchospora capillacea, Seleria verticillata. At Killalenny Mt.: Orectophyllum Ura-Urai, Betula Jeffreyana, Nov. 28. (Saturday). Continued E. palustris group in western U.S. E. xypidiformis can be readily traced from Mexico through Texas and north to N.E. Utah, and in a modified form through a large part of Wyoming. It is merely a phase of the soft-stemmed plants and occurred in Mexico with colored to dark spikelets. This E. xypidiformis runs into the "perlonga" phase of the Mexican boundary and orientates northwards with E. macro- tochys and the soft-stemmed twisted plants which Thoreenje and Bark have called E. torta, ending up, in part in the normal-spike variation of E. torta found in Kansas. The Clarkes + Wyoming material, mostly with hard-ened seeds, is structural to plants of eastern Oreg & Washington. All this material seems to form a high species. 1) California material (scales) running into E. perlonga in low country of middle California.
