New eleocharis (Cyperaceae) from Venezuela

Seven new species of Eleocharis are described based on study of material from the Venezuelan Guayana: Eleocharis alveolaloides, E. atrospiculata, E. ayacuchensis, E. eglerioides, E. liesneri, E. steyermarkii, and E. tenezuelensis. Eleocharis squamigera is represented in the Venezuelan Guayana by a newly described subspecies, E, squamigera subsp. straminea, differing primarily in the pale color of the rhizome scales and glumes. Two new forms are also described, E. debilis forma anomala, differing from the typical form in having 3-branched styles and trigonous achenes mixed with the characteristic 2-branched styles and biconvex ones of this species, and E. geniculata forma brunnea, differing from typical E. geniculata in its brown achenes.
