Each leaf is narrow, 2-20cm long (exceptionally up to 100cm) and 0.5-3mm wide; they can be either evergreen, winter deciduous, or dry-season deciduous. They broaden to a swollen base up to 5mm wide where they attach in clusters to a bulb-like, underground rhizome characteristic of most quillwort species, though a few (e.g. ''I. tegetiformans'') form spreading mats. This swollen base also contains male and female sporangia, protected by a thin, transparent covering (velum), which is used diagnostically to help identify quillwort species. They are heterosporous. Quillwort species are very difficult to distinguish by general appearance. The best way to identify them is by examining the megaspores under a microscope

 ==About genus ''Isoetes''==
-'''''Isoëtes''''', also written '''''Isoetes''''' and commonly known as the '''quillworts''', is the genus of plants in the class [[w:Isoetopsida|Isoetopsida]] and order '''Isoetales'''. The order Isoetales is sometimes placed in the class Isoetopsida, sometimes in the Selaginellopsida or Lycopsida. They are considered "[[w:fern ally|fern allies]]". There are about 140-150 species, with a [[habitat::w:cosmopolitan|cosmopolitan distribution]] but often scarce to rare. Some [[w:botanist|botanist]]s split the genus, separating two South American species into the genus '''''Stylites'''''.

 ==Habitat and Geographical Distribution==
