The type forms stand midway in the species; - the flat phytic extreme being E. xypriopinus from Brack., the lax extreme represented by mountain plants from Wyoming Mountains. Typical E. macrostachya may be characterized as follows: Spikelets with strongly convex scales, usually semi-cartilaginous, the spikelets thus having a series of constructions, much as in Cyperus esculentus, or E. holophila. Inner scale usually very short and more or less convex, either spatulate (see in E. unipennis) or several belted (as in E. folistris. Color usually hardened, sometimes flat. Aster? sheath frequently twisted (as in Tricostatus). Potentially specimens to Carnegie Museum (11 specimens of Elecharis from Utah). Feb 27 (Thursday), Received E. African specimens of Elecharis from Kew. Continued some of the Georgia plants from Sylvester. Xyris antiqua. The most conspicuous Xyris, found just next adjacent to Barrancania, it has a large spike like - heads; and and a non-twisted stalk. Sporobolus tetraphilus Harper. The most conspicuous grass forming very clumps. Pycnothura ramiflora, grows among the clumps of Sporobolus. Polystyla ramosa, and P. cruciata and P. lutea, with Muhlenbergia gramineflie, and Chloris Aliflamus, Oxyrallis piliformos and Eryngium ludovicianum - grow together in profusion. The common Hypericum is H. zygosciculatum, next to Rhea Aliflones providing the most color. The thicket shrubs, Cyrrila racemipera, Cliftonia.
