本文提出台灣產裂緣花科裂緣花屬的分類位階訂正，並附有插圖以辨識四個變種。台灣產裂緣花屬植物計有一種四變種，即倒卵葉裂緣花、李棟山裂緣花、圓葉裂緣花及高山裂緣花。其中二變種為新組合的分類群，亦即李棟山裂緣花（Shortia rotundifoila (Maxim.) Makino var. ritoensis (Hayata) T.-C. Huang & A. Hsiao, comb. nov.）與圓葉裂緣花（var. subcordata (Hayata) T.-C. Huang & A. Hsiao, comb. nov.）。

This is a precursory note of the Family Diapensiaceae for the Flora of Taiwan, volume four. Special attention is paid to the revision of the taxonomic rank. One species and four varieties of Shortia are recognized in Taiwan: S. rotundifoila (Maxim.) Makino var. rotundifoila, var. ritoensis (Hayata) T.-C. Huang & A. Hsiao, var. subcordata (Hayata) T.-C. Huang & A. Hsiao, and var. transalpinia (Hayata) Yamazaki. Two varietis are treated under new combinations, i. e. var. ritoensis (Hayata) T.-C. Huang & A. Hsiao, comb. nov. and var. subcordata (Hayata) T.-C. Huang & A. Hsiao comb. nov.
