Family/Plant species ST/EI (a) Site (b) Habitat (c) Adiantaceae Adiantum
The filicalean genera Matonia, Dennstaedtia, Adiantum
, and Pteridium occur in a pectinate arrangement at successively more distal nodes below a clade that consists of Cyathea + Acrostichum as sister group to Onoclea + Polypodium.
Ferns in the mesic woods include Adiantum
pedatum, Athyrium pycnocarpon, Botrychium virginianum, Cystopteris protrusa, Dryopteris goldiana, Dryopteris carthusiana, Onoclea sensibilis, and Polystichum acrostichoides (rare).
The low elevation riparian habitat is directly threatened by invasive plants such as Adiantum
raddianum, Blechnum appendiculatum Willd.
In many freshwater springs and oases near the Dead Sea in Israel and Jordan and in the southern Sinai, Adiantum
capillus-veneris grows on dripping water in shady places with the orchid Epipactis veratrifolia.
In the same paper, details of this chemical cell wall were presented for Adiantum
Since his review, a good light micrographic illustration of a stage 2 foliar endodermis in Adiantum
appeared in Wylie (1948).
Biogeographic disjunction between eastern Asia and North America in the Adiantum
Similarly detailed descriptions have been provided for the shoot apices of Histiopteris, Hypolepis, Dennstaedtia, Adiantum
, and Osmunda (Imaichi, 1977, 1980, 1982, 1984, 1988).
Spore abortion is a key character that provides evidence of hybridization (Moran, 2004), and it has been found in many hybrids in different genera such as Adiantum
(Moran and Watkins, 2002; Rojas-Alvarado and Herrera-Martinez, 2012), Asplenium (Rojas-Alvarado and Chaves-Fallas 2010), and Polystichum (Barrington 1985).
