形態特徵

• Perennial herbs. Caudax with clustered leaves and stolons, stolons 6–10 cm long, terete, pubescent.
• Leaves rosulate, opposite, papyriferous, radical leaves with obscure petiole, blade obovate-oblong or spatulate. 3–5 cm long including petiole, 1–2 cm wide, base gradually narrowed, attenuate into obscure petiole. incised or crenate-dentate, apex rounded to obtuse. glabrous or pubescent on both surfaces; leaves on stolons subsessile, opposite, sometimes alternate, obovate, 1–1.5 cm long, 0.5–1 cm wide, apex acute or obtuse, acute-serrate.
• Inflorescence racemose, generally terminal on caudex, rarely at apex of stolons, 5–10 cm long, loosely 5–10-flowered; bracts linear-deltoid, ca. 1.5mm long; pedicels 0.5–1 cm long; calyx campanulate, 5–8 mm long, 5-lobed, lobes deltoid, ca. 3 mm long; corolla purple. bilabiate, spotting type B, 0.5–1.3 cm long, stamens 4, didynamous.
• Capsule enclosed by persistent calyx, globose, 3–4 mm across. Seeds narrowly ellipsoid, ca. 0.5 mm long, brown.
• Chromosome number 2n =6x=60. <li>This species is very similar to <i>M. faurie</i>i, but can be distinguished by its smaller leaves, type B spotting on corolla, 3- or 4-colpate pollen grains and hexaploid karyotype. This species grows in grassy places on the campus of National Tainan Teachers College, in southern Taiwan. It might have been introduced during the planting of ornamentals and become naturalized on the campus. Since our present knowledge of this species is insufficient, further study is needed.</li>
