Entwives
From the One Wiki to Rule Them All, the Lord of the Rings Encyclopedia.
Entwives were female Ents.
Physically they probably looked a lot like their male counterparts but possibly smaller in build. Like the males they looked after the growing things of Middle-earth, but Entwives preferred smaller plant life such as: small trees, grasses, fruit trees, flowers, and vegetables, while males tended the larger trees.
[edit] History
Like all Ents they tended their lands in the vast primordial forests of Middle-earth throughout the Elder Days, but sometime in the distant past, possibly starting in the Second Age they became estranged from their husbands. They moved further East crossing the Great River Anduin and began living in the Brown Lands tending lush gardens; However with the rise of Sauron throughout the Second Age these lands were destroyed. After that they disappeared and everything about them was the subject of rumor and conjecture. It is possible that they went to Shire, because Sam mentions that his cousin saw a walking tree.
[edit] Peter Jackson Movie Trilogy
In The Two Towers, Treebeard tells Merry and Pippin about the Entwives and how they became lost to them. He also asks them if there are Entwives living in The Shire.
