辨析
This species may be conspecific with Liparis makinoana Schlechter, from Japan, given that the descriptions of the two coincide. In Japan, the name L. makinoana has been misapplied to different taxa (e.g., by Tsutsumi & Yukawa, Bull. Natl. Mus. Nat. Sci., Tokyo, B, 34: 89-94. 2008).This species may be conspecific with Liparis makinoana Schlechter, from Japan, given that the descriptions of the two coincide.

宝岛羊耳蒜栽培
地生种可用腐殖土4份。沙和碎苔藓各1份组成基质盆栽；附生种可用树皮块、木炭、风化火山岩、蛇木屑等基质盆栽。
旺盛生长时期每1-2周施一次复合肥，浓度0.05%-0.1%；生长时期要求充足的水分供应，秋季温度下降时逐步减少浇水。在休眠期，盆栽基质保持微干，停止施肥。
中温或高温环境栽培；有休眠期或无休眠期。羊耳蒜属植物与一般的兰花相比，需要较阴的环境，并保持较高的空气湿度。
