茄屬為一種類多且形態多變的大屬，包含了近75%的茄科植物，臺灣已紀錄的有20種，最近我們在東部蘭嶼進行植物調查時發現另一新紀錄植物——宮古茄（Solanum miyakojimense Yamazaki & Takushi），該種原為琉球宮古島之特有種，發表於1991年。本文提供該種的形態描述、描繪圖與彩色圖片。

Solanum is a large and morphologically diverse genus comprising almost 75% of the species in the family Solanaceae. Twenty species were recorded in Taiwan. Solanum miyakojimense Yamazaki & Takushi was published in 1991 as an endemic species in Miyako Islands, Ryukyu. A careful examination of herbarium collections supplemented by field studies confirmed the occurrence of this species in Lanyu, Taiwan. In this report we provide the description, line drawings, and colored photographs taken from the natural habitat to aid in identification of this species.
