Abstract. Isoetes L. is a pteridophyte which
belongs to Isoetaceae. It has various habitats of submersed, amphibious,
terrestrial and alpine. It has two type of spores; megaspore and microspore. Isoetes
was divided to four sections by the criteria of megaspore by N. E. Pfeiffer

in Isoetes. The flap-like portion of ligule protects young leaf
primordium, whereas the basal glossopodium is large, complicated and remain
embedded in leaf tissue and functions as a haustorial structure. The ligule is
comparable to the prophyll of monocots and ochreole of Equisetum.

Abstract. Phylogenetic trees derived from nuclear

e.g., an Australasian clade, a southern Africa clade, and a clade
containing species from Europe, northern Africa, and western North America.

Phylogenetic relationships of Isoëtes (Isoëtaceae) in China as revealed
by nucleotide sequences of the nuclear ribosomal ITS Region and the second
intron of a leafy homolog. American Fern Journal 94 (4): 196-205. Abstract:
Isoëtes is an ancient lycopod lineage with a highly conserved morphology
that provides few morphological characters to resolve the phylogeny of its
species. Species appear to have evolved by divergence and allopolyploidy. The
basic diploids I. hypsophila, I. taiwanensis, and I. yunguiensis
and the tetraploid I. sinensis occur in China. Analysis of ITS sequences
indicates that the Chinese Isoëtes species are part of an Australasian
clade including I. brevicula from Western Australia and I. kirkii
from New Zealand. Two distinct cloned sequences of the second intron of a leafy
homolog were recovered from I. sinensis supporting the hypothesis that I.
sinensis is an allotetraploid. One of the I. sinensis cloned
sequences was similar to the I. taiwanensis sequence and the other
cloned sequence was similar to the I. yunguiensis sequence identifying I.
taiwanensis and I. yunguiensis as the likely parents of I.
sinensis. Other cloned sequences recovered from I. sinensis were
recombined parts of the two distinct sequences. Morphological evidence
supporting an allotetraploid origin of I. sinensis is found in its
larger microspore size and intermediate megaspore texture compared to I.
taiwanensis, and I. yunguiensis.
