Three new species of Eleocharis are described from southern Brazil. Eleocharis pauciglumis is a member of Eleocharis subg. Limnochloa and is similar to E. acutangula. Eleocharis atrobrunnea and E. parvispicula belong to Eleocharis subg. Eleocharis sect. Eleogenus and are similar to Eleocharis flavescens and E. sellowiana. Morphological descriptions, illustrations, information on habitat, and keys...
Eleocharis cryptica (Cyperaceae), known from pine-oak forest in Durango, Mexico, is described and illustrated. It belongs to Eleocharis subg. Eleocharis ser. Tenuissimae and can be distinguished by its diminutive size, with culms 2–13 mm long (including spikelets 1.3–1.7 mm long), and the folliform prolongations of its upper sheaths. It is the smallest species of Eleocharis thus far known.
Systematic study of several species complexes inEleocharis subgen.Limnochloa resulted in the discovery of a new South American species,E. steinbachii. This new species is closely related toE. acutangula, differing in features of the perianth bristles, achene, tubercle, and narrow neotropical distribution. A description and illustration of the new species is provided along with a key to separate it...
New geographic records ofEleocharis obtusetrigona from the Galapagos islands, Guatemala, and El Salvador are reported. A description and illustration ofE. obtusetrigona are provided, along with a key to separate it from other Central and South American species ofEleocharis subg.Limnochloa with which it has been frequently confused.
