Miss. Code § 27-35-61
In assessing land, a description of it as a part of a designated tract or division, shall be held to embrace such part as is the subject of separate ownership, as one tract or division, whether owned by one or several jointly. When part of a designated tract or division shall be sold for taxes, the sale shall pass the title of such part as was the subject of such separate ownership when it was assessed. The sale of a specified number of acres of a tract containing more, or a specified portion of a tract, shall pass an undivided interest in the whole tract equal to the proportion which the number of acres or portion sold bears to the whole tract. When part of a known tract or division of land is assessed by a description which identifies it, any other part of it which is assessed but not so identified, shall be held to embrace all of such tract or division not included in the part identified. Parol testimony shall always be admissible to apply a description of land on the assessment roll, or in a conveyance for taxes, where such testimony will show what land was assessed and sold, and there is enough in the description on the roll or conveyance to be applied to a particular tract of land by the aid of such testimony.
