中文摘要 | 本文報導臺灣特有的百合科新種植物:高山油點草(Tricyrtis ravenii)。它屬於油點草屬Hirta組,該組過去已發表的植物僅毛油點草(特產日本),臺灣油點草(產臺灣及硫球)以及毛果油點草(特產臺灣)三種。由於高山油點草外表略似臺灣油點草,典藏於臺灣各標本館的高山油點草標本幾乎全都被訂名為後者;但野外採樣及實驗溫室栽培植物形態觀察顯示這兩種植物的花部特徵,習性,海拔分佈等都有許多明顯差異,因此發表高山油點草為新種。本文提供高山油點草的分類處理,線繪圖,野外照片及花部之顯微特徵,染色體核型分析以及臺灣的地理分布圖,並製做油點草屬Hira組的檢索表,以利辯識。 |
英文摘要 | Tricyrtis ravenii (Liliaceae) is reported here as a new species endemic to Taiwan. It belongs to sect. Hirate, which comprises three species heretofore, namely T. hirta (Japan mainland, mainly on the Pacific side), T. formosana (aiwan and Iriomote, Japan) and T. lasiocarpa (Taiwan). Bearing a superficial resemblance to Tricyrtis formosana, specimens of T. ravenii in most herbaria were near always erroneously annotated as the former or its synonyms such as T. stolonifera. Careful morphological studies of these plants both from the field and in the experimental greenhouse reveal that they differ from t. formosana significantly in floral details, habit, occur at higher elevations and deserve recognition of a new species. A taxonomic treatment, line drawings, field and micro-photographs of epidermal characters, karyotype analysis, and a map showing their distribution on this island is provided. A key is prepared to aid in the identification of all four species of Tricyrtis sect. Hirtae. |
