Arbuscular mycorrhizal colonization in field-collected terrestrial cordate
gametophytes of pre-polypod leptosporangiate ferns (Osmundaceae, Gleicheniaceae, Plagiogyriaceae, Cyatheaceae).
The vine variety has leaves that are green measured 4-5 cm wide and 9-10 cm long with acute tips and cordate
to acute base.
5-5 mm, cuculus cordate
to orbicular, bent around the stamens, 11-13 X 6-7 mm; stamens yellow, 6-7.
asiatica was describe as having a rounded apex leaves, deeply cordate
stipulate base and petiole of height of about 20 cm.
Leaf blade oblong-elliptic to elliptic-ovate, 13-45 cm long; base asymmetrical in sympodial leaves, cordate
to deeply auriculate, the biggest lobe half or completely overlapping the petiole; pinnately veined with 8-16 secondary veins; ciliate and minutely pubescent on both surfaces.
At this time, almost 50% of gametophytes were cordate
or slightly asymmetric in shape (Fig.
Besides, it has apex acuminate, base cordate
, margin entire or dentate, sub coriaceous, fulvous tomentose, 7-nerved at base.
Leaf shape changed from cordate
to a slightly elongated cordate
by the increase in length particularly at wavelengths shorter than 449 nm and the general decrease in width at all treatments except the shortest wavelength interval.
On older trees, the leaves are generally 5-15 cm long, unlobed, cordate
at the base and rounded to acuminate at the tip, and serrated on the margins.
cordifolia have orbicular leaves, rounded or cordate
at base, often bullate, usually green; inflorescence spherical at first, usually becoming umbraculiform with spreading branches; flowers mostly spreading or erect, broadly campanulate; petals broadly ovate to orbicular, abruptly contracted into the claw (Yeo, 1966).
Subcordate to subcircular, slightly longer than wide, 39 [micro]m long, 32 [micro]m wide; operculum cordate
, almost covering the orifice and obscuring the lingula, 26 [micro]m long, 22 [micro]m wide.
have 3 varieties including Puk Bung Thai (bigger stem, cordate
leaf), Puk Bung Jeen (green stem, hastate leaf) and Puk Bung Dang (greenish purple stem).
