The iodite ion, or iodine dioxide anion, is the halite with the chemical formula IO−
2. Within the ion the Iodine exists in the oxidation state of +3.
Iodite anion
[edit]Iodites (including iodous acid) are highly unstable and have been observed[1] but never isolated.[citation needed] They will rapidly disproportionate to molecular Iodine and Iodates.[2] However, they have been detected as intermediates in the conversion between iodide and iodate.[3][4]

Iodous acid is acid form of the iodite ion, with the formula HIO2.
Other oxyanions
[edit]Iodine can assume oxidation states of −1, +1, +3, +5, or +7. A number of neutral iodine oxides are also known.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
