의문1 : 민들레는 어디로 갔을까요?
정리를 해놓고 보니 흰민들레와 비슷하게 총포가 위로 향하고 꽃이 노랗게 피는 민들레(Taraxacum platycarpum)가 없어졌습니다.
학명으로 여기저기 검색을 해보고 이명까지 다 뒤져봐도 흔적이 없습니다.
그렇다면 꽃은 서양민들레보다 약한 황색으로 피고 총포가 위로 향하는, 소위 토종민들레는 어디에 속하는 것일까요?
의문2 : 서양민들레의 정체는??
서양민들레의 학명인 Taraxacum officinale를 검색하다가 뜻밖의 상황에 맞닥뜨렸습니다.
Taraxacum officinale라는 학명은 특정 종이 아니고 민들레속 민들레절(Taraxacum sect. Taraxacum)에 속하는 식물들의 통칭이라는 겁니다.
유럽에는 민들레절에 1,000여종의 식물이 확인되었다고 하고 중국의 FOC에는 Taraxacum oblongatum, Taraxacum rhodopodum, Taraxacum yinshanicum의 3종이 여기에 속한다고 합니다.
"The name Taraxacum officinale is generally used to cover the diversity of this section. Until recently, the effective lectotypification restricted the usage of this name to what is most often called T. sect. Crocea M. P. Christiansen, a northern and alpine section. A corrected typification, returning the name to the most common usage (in the sense of T. sect. Ruderalia) was published recently (Kirschner & Štěpánek, Taxon 60: 219. 2011). From now on, the name T. officinale in its broad sense may be used for what is here treated as T. sect. Taraxacum (T. sect. Ruderalia), and the older records under T. officinale usually belong to this section, which is widespread in China."
서양민들레에만 수없이 많은 종이 있다는데 우리가 서양민들레라고 하는 것의 정확한 학명은 무엇일까요?
Herbs 8-25 cm. Petiole usually narrow; leaf blade mid-green, oblanceolate, 6-15 × 2-3.5 cm, subglabrous to sparsely arachnoid, pinnatilobed, pinnatisect, or rarely undivided; lateral lobes 3 or 4 pairs, broadly triangular, obtusely deltoid, or broadly linear, patent to recurved, distal margin sparsely dentate or entire, apex obtuse; interlobes broad, sometimes spotted dark purple, margin entire to sparsely dentate; terminal lobe broadly triangular, apex broadly obtuse. Scapes single or rarely branched with an ascending side scape, brownish green, equaling to slightly overtopping leaves, scattered arachnoid but densely arachnoid below capitulum. Capitulum 3-4 cm wide. Involucre mid-green, 1-1.2 cm wide, base ± rounded. Outer phyllaries 9-15, mid-green to pale green, ± not imbricate, linear-lanceolate to narrowly lanceolate, outermost ones 6-9 × 0.8-2.5 mm and ca. 1/2 as long as inner ones, loosely appressed, distinctly veined, border indistinct, paler green to membranous, often suffused pink, and 0.1-0.3 mm wide, margin ± densely ciliate, apex with a green or purplish thick horn to 1.5 mm; inner phyllaries 1.1-1.5 cm, apex flat to corniculate. Ligules yellow; outer ligules outside striped grayish purple; inner ligules with blackish to purple apical teeth. Stigmas pale green. Anthers polliniferous; pollen grains irregular in size. Achene ± brown to grayish brown, 4.2-4.6 × 1.1-1.3 mm; body tuberculate throughout, apically densely tuberculate-squamulose, gradually narrowing into a subconic 1-1.2 mm cone; beak 7-10 mm. Pappus yellowish, ca. 6 mm. Fl. spring, occasionally also to late summer. Agamosperm. 2n = 24*.
● Abandoned fields, grasslands, along paths and roads; 800-2000(-2800) m. Anhui, Fujian, Guangdong, Guizhou, Hebei, Heilongjiang, Henan, Hubei, Hunan, Jiangsu, Jilin, Liaoning, Nei Mongol, Shaanxi, Shandong, Shanxi, Sichuan, Xizang, Zhejiang.
The stated distribution of Taraxacum mongolicum is based on the report in FRPS (80(2): 34. 1999), but material has not been revised and can only be confirmed for Hebei, Shanxi, Sichuan, and Xizang. However, the reported occurrences in Gansu, Qinghai, Taiwan, and Yunnan are improbable, and material under that name in herbaria from these provinces belongs to other taxa.
For Taraxacum mongolicum var. caninum and T. mongolicum var. laeve see the discussion of T.sect. Mongolica, above.
Herbs 12-40 cm tall, robust. Petiole narrow; leaf blade deep green, narrowly oblanceolate, (6-)10-18 × 2-4 cm, arachnoid, margin subentire, dentate, shallowly lobed, or rarely to deeply pinnatisect; lateral lobes 3-5, broadly triangular, recurved; interlobes (when developed) with margin entire. Scapes brownish green, overtopping leaves, white arachnoid but whitish to brownish tomentose below capitulum. Capitulum 4-5 cm wide. Involucre 1-1.3 cm wide, base ± rounded. Outer phyllaries 14-19, subimbricate, ovate-lanceolate to ovate, 8-15 × (2.5-)3-4.5(-6) mm, appressed to loosely so, not distinctly veined, median part blackish green, with a whitish green to whitish 1-2 mm wide border, margin conspicuously densely whitish ciliate and blackish callose below apex (sometimes surface arachnoid in upper ca. 1/3); inner phyllaries 1.5-1.7 cm. Ligules yellow; outer ligules outside striped faintly purplish gray. Stigmas blackish to dark green. Anthers without pollen or polliniferous; pollen grains irregular in size. Achene grayish brown to light brown, (4.5-)5.5 × 1.5-2 mm; body spinulose-squamulose in upper ca. 1/3, tuberculate below, ± abruptly narrowing into a thick subcylindric 1.2-1.4 mm cone; beak ca. 9.5 mm. Pappus yellowish dirty white, 7-9 mm. Fl. summer. Agamosperm.
● Subalpine meadow slopes; 1900-3000 m. Gansu, Hebei, Shanxi.
The report ofTaraxacum platypecidumfor a number of additional provinces and for Korea and Japan (FRPS 80(2): 43 1999; Higher Pl. China 11: 778. 2005) is probably incorrect. However, although not yet seen by the authors among the specimens studied, the species should be looked for in the mountainous provinces adjacent to Hebei and Shanxi.
흰털민들레가 있기는 있는 것일까요? 첨부한 영문기재문의 마지막부분에 "한국과 일본에서도 보고되었는데 아마도 오류일 것이다"라고 단정적으로 말하고 있네요. 중국에서도 허베이와 산시성근처에만 있다네요.
