The Xyridaceae are a family of flowering plants. This family has been recognized by many taxonomists and is known as the yellow-eyed grass family. The APG II system, of 2003 (unchanged from the APG system of 1998), also recognizes this family, and assigns it to the order Poales in the clade commelinids, in the monocots.

Rosulate to caulescent, low and delicate to tall and coarse, perennial to annual, terrestrial (rarely aquatic) herbs, mostly heliophytes of highhydroperiod acidic soils. Roots mostly slender, diffuse-fibrous, with root hairs. Axis sympodial or monopodial.

黄眼草科 Xyridaceae 禾本目 是 单子叶植物 的一个目。 2003年根据「 植物 亲缘关系分类的 APG II 分类法 」将原来分在 莎草目 、 帚灯草目 、 谷精草目 和 鸭跖草目 中的部分 科 合并为一个禾本目。

黄眼草科（学名：Xyridaceae C. Agardh (1823)）是禾本目下一个科，单子叶植物，4属，270种，分布于热带和亚热带地区，大部产美洲，我国只有黄眼草属Xyris L. 1属，6种，产西南部至东部。

The Xyridaceae are distinctive in being perennial or annual herbs with a terminal, scapose bracteate head or dense spike, bracts subtending showy flowers with ephemeral, usually yellow petals. From: Plant Systematics (Third Edition), 2019

Common name: Yellow-eyed Grass Family. As recognized more narrowly (excluding Abolboda, Aratitiyopea, and Orectanthe into the Abolbodaceae), a family of 2 genera and about 300-325 species, nearly cosmopolitan (most diverse in tropical and subtropical regions, and especially South America).

黄眼草科，又名 蔥草科， [1] 包括5 属 约270 种，分布在全球 热带 和 亚热带 地区， 中国 只有1属7种。 本科 植物 为一年生或多年生 草本 植物， 叶 基生，线形，基部有鞘； 花 两性，稍两侧对称； 花萼 和 花冠 3裂； 果实 为 蒴果，3瓣裂。 种子 极少。 鹦山草属 Aratitiyopea Steyerm. & P. E. Berry, 1984. 1981年的 克朗奎斯特分类法 将其列入 鸭跖草目，1998年根据 基因 亲缘关系分类的 APG 分类法 将其分为两 科 —黄眼草科和 阿波波达草科，将生长在 南美洲 的阿波波达草属 植 …

Plants in the Xyridaceae are annual or perennial herbs growing in wetlands or other wet habitats. The leaves grow alternately along the stem in 2 ranks and are set edge-to-stem. The leaves are long and slender, with parallel veins. The flowers are arranged at the tip of the stem in a spike that resembles a cone.
