| 개요 | 향용머리는 잎이 주걱형 혹은 타원형으로 가장자리가 거치가 있어 잎이 선형이고 전연인 용머리와 구별된다. 또한 벌깨풀은 향용머리에 비해 잎이 심장형의 넓은 원형으로 쉽게 구별할 수 있다. 향용머리는 중국, 유럽 등에서도 원예용으로 재배되고 있거나, 약용식물로 이용되고 있으며(MartínezVazquez et al., 2012), 국내 유입은 재배식물 또는 관상용으로 식물원이나 화원에 도입된 후 국내에 정착한 것으로 생각된다Plants annual, branched herbs, Stems numerous. (6−)22−45 cm long, simple or branched, usually erect or ascending; internodes 3−4.7 cm long; sparsely covered by short minutely retrorse hairy hairs, purplish. Leaves basal cauline leaves withering early, oblong to ovate-triangular, 1.7−2.4 cm long 0.8−1.2 cm width, margin crenate to dentate; obtuse at apex, usually attenuate or rarely cordate at base, on both surfaces with a short eglandular indumentum, petiole as long as blade, 1.2−1.8 cm long, shorter upward; upper blades lanceolate to linear-lanceolate, 1.4−2.1 cm long 0.4−0.9 cm width, yellow glandular, sparsely minute hairy on vein, apex obtuse, base rounded to broadly cuneate, margin triangular-dentate or sparsely serrate, with basal teeth sometimes spinescentdenticulate, with spines. Inflorescence with petiolate to subsessile bracts, oblong to lanceolate, 0.2−0.8 cm long 0.1−0.5 cm width, weakly crenate at margin with spines, usually equaling or longer than sepals, sparsely appressed hairy. Verticillasters six flowered in the node, loose, in 5−12 upper nodes of stems and branches; pedicels 3−5 mm long, horizontal after anthesis; Calyx bilabiate, tubular, nearly actinomorphic, gibbous at base, 7−10 mm long, golden glandular, pubescent especially basally, purple veined, 2-lipped to 2/3 its length, teeth unequal, 1.5−2.5 mm long; upper lip 3 teeth divisions 1/ 4−1/3 of lip, teeth subequal, triangular-ovate, apex acute; loewr lip 2-lipped, lanceolate mucronate teeth, hispidulous, puberulent hairs outside, interior surface of calyx teeth hirsute and with pilose hairs inside, rest glabrous. Corolla medium bluish purple, 1.5−2.5(−3.2) mm long, dilated beyond throat, the tube exserted from calyx, white pubescent outside annulate or hemi-annulate inside toward base upper lip short navicular, ca. 1/4 as long as tube; lower lip 3.8−5.2 mm long, middle lobe of lower lip dark purple spotted; filaments filiform, glabrous; anther 2-locule, elliptical, parallel. Pistil 1; ovary 4-locule; style gynobasic, 3.9−5.2 mm long, exserted, 2-cleft at apex. Nutlets 1.8−2.3 mm long and wide, oblong, apex truncate, with a prominent V-shaped attachment scar, smooth, balckish brown. |
