臺灣植物誌之觀察（22）──筋骨草屬（唇形科）

Notes on the Flora of Taiwan (22)-- The Genus Ajuga L. (Lamiaceae)

本文訂正臺灣產筋骨草屬植物為4種，分別為網果筋骨草（Ajuga dictyocarpa Hayata），日本筋骨草（A. nipponensis Makino），矮筋骨草（A. pygmaea A. Gray）和臺灣筋骨草（A. taiwanensis Nakai ex Mmurata）及一新歸化種匍伏筋骨草（A. decumbens Thunb.）。文中比較各種的外部形態、花粉特徵、染色體數目和地理分佈等特徵。並提供檢索表做為鑑定之用。在染色體數目方面，除網果筋骨草為2n=64外，其餘種類皆為2n=32。

Four native species of Ajuga L. (Lamiaceae), i. e., A. dictyocarpa Hayata, A. nipponensis Makino, A. pygmaea A. Gray, and A. taiwanensis Nakai ex Murata and one naturalized species, A. decumbens Thunb. are recorded in Taiwan. SEM micrographs of pollen grains, chromosome counts, a key to species, species descriptions, and distribution maps are provided. The chromosome number of all species is 2n = 32 except A. dictyocarpa Hayata of which is 2n = 64.
