	abstract = {The name Isoetes pedersenii H.P. Fuchs (Lycophyta), a species known only from the Mburucuy{\'a} National Park, Corrientes, Argentina, is validated. Observations were carried out on herbarium material with stereoscopic, light and scanning electron microscopes. The species is described and typified. A diagnosis and discussion about its distribution and its relationship with the morphology of other species of Isoetes are provided.},

	abstract = {The morphology and wall ultrastructure of megaspores and microspores of Isoetes sehnemii that grows in Brazil were analyzed as part of the study of the Isoetaceae present in Southern South America. The observations were performed with light, scanning and transmission electron microscopes. The megaspores are trilete, 350-450μm in equatorial diameter. The surface is reticulate. In section, the sporoderm is 100μm thick including the ornamentation. The wall is composed of a siliceous perispore, which consists of short fused flatten, elements forming a three-dimensional mesh. The exospore has two zones of different structure. The endospore is fibrillar. The microspores are monolete, 21-27μm in equatorial diameter. The sporoderm is composed of a sporopollinic rugulate perispore. A space between the para-exospore and the exospore is evident. The exospore is compact. The endospore is fibrillar. The ultrastructural analysis akes hoologies evident concerning structure and organization of the layers belo the perispore in both spore types. A possible similarity and stability in the ultrustructure of the present spores and fossils could be also inferred. In addition, there would be a correlation among the plant habitat, the spore ornamentation and the geographic distribution.},

	abstract = {A new species, Isoetes libanotica Musselman, Bolin \&R. D. Bray (Isoetaceae, Lycophyta), is described from Akkar District of northern Lebanon. It is a seasonal terrestrial species of basaltic soils, diploid (2n = 22), with complete velum coverage. Megaspore diameter ranges from 338 to 477 lm with remote, low tuberculate ornamentation and a low to obsolete equatorial girdle; microspore length ranges from 25 to 30 lm, with echinate ornamentation. At the type locality of I. libanotica, two other Isoetes L. species occur sympatrically. These superficially similar Isoetes species can be differentiated from I. libanotica using megaspore characters; I. duriei Bory has larger alveolate megaspores and I. olympica A. Braun has a prominent equatorial girdle. Copyright {\textcopyright} 2011 BioOne All rights reserved.},

	abstract = {Microspore wall morphogenesis of Isoetes piedmontana was studied with SEM and TEM. The microspore wall consists of four layers: Perispore, paraexospore, exospore, and endospore. Immediately after meiosis, the paraexospore forms around the microspore. The exospore forms next between the cell membrane and the paraexospore. Finally, the perispore is deposited on the paraexospore, and the endospore is formed within the exospore. The paraexospore, exospore, and endospore are largely derived from the cytoplasm of the microspore. The sporopollenin materials of the perispore are derived from the secretory tapetal cells along the inner sporangial wall. {\textcopyright} 2011 by The University of Chicago. All rights reserved.},
