	abstract = {Isoetes mattaponica is a rare quillwort of freshwater tidal rivers of eastern Virginia with a somatic chromosome number of 2n = 22. Megaspores have low regulate muri on both the proximal and distal surfaces; the girdle is broad. Microspores are echinate-spinose with ornamented spines. Isoetes mattaponica may be one of the parents of several polyploids in the Southeastern United States.},

	abstract = {Isoetes yunguiensis, a basic diploid species with a chromosome number of 2n = 22, is described and illustrated. This species occurs on the Yunnan-Guizhou Plateau in southwest China. It is similar to I. japonica in its appearance and emergent aquatic habit. Herbarium specimens of I. yunguiensis previously have been misidentified as I. japonica. Isoetes yunguiensis differs from I. japonica in megaspore and microspore morphology and chromosome number.},

	abstract = {Despite its ancient origins, worldwide distribution, and adaptation to diverse habitats, Iso{\"e}tes species have a highly conserved morphology, making it difficult to resolve phylogenetic relationships using morphological characters. In this paper, we report the results from various analyses (maximum parsimony, maximum likelihood, and Bayesian inference) for Iso{\"e}tes species from around the world based on nucleotide sequences from the nuclear internal transcribed spacer (ITS) and chloroplast atpB/rbcL intergenic spacer regions. The trees resulting from our analyses of the combined data contain six major well-supported clades (bootstrap >= 90\%, posterior probabilities = 1.00): A clade with possible Gondwanan affinities (I. australis, I. coromandelina, I. panamensis, I. cubana, I. jamaicensis); a South African clade (I. capensis, I. toximontana, I. stellenbossiensis, I. stephansenii); a largely Northern Hemisphere clade (I. nuttallii, I. orcuttii, I. minima, I. dixitei, I. abyssinica, I. olympica, I. longissima, I. velata); an Asian/Australasian clade (I. drummondii, I. gunnii, I. pusilla, I. kirkii, I. muelleri, I. taiwanensis, I. japonica, I. yunguiensis, I. habbemensis); a Mediterranean clade (I. histrix and I. setacea); and a poorly resolved clade consisting of 12 new world species (American species complex). Our results are compared to past classifications and various biogeographical scenarios are explored. {\textcopyright} Copyright 2006 by the American Society of Plant Taxonomists.},
