4. Dandelions in Central Asia
- Creator:
- Kirschner, Jan, Štěpánek, Jan, and Klimeš, Leoš
- Type:
- article and TEXT
- Subject:
- Central Asia, Compositae, Lactuceae, Ladakh, Taraxacum, and taxonomy
- Language:
- English
- Description:
- A taxonomic revision of Taraxacum sect. Leucantha Soest is presented. Species in this section are mainly characterized by the pale bordered and appressed outer involucral bracts, achenes covered with subsparse coarse spinules, thick cylindrical cone and a relatively short, thicker rostrum, and often white or pale yellowish flowers. They occur in subsaline wet meadows and steppe depressions over a large area including Mongolia, South Siberia, NE, N and W China, Tibet, the Western Himalayas, Tadzhikistan, Kyrgyzstan and E and NE Kazakhstan. Eighteen species are recognized, seven of them described as new: Taraxacum niveum from the Altai and Dzhungaria, T. candidatum centred in Ladakh, Tadzhikistan and Kyrgyzstan, T. album from Kyrgyzstan, T. flavidum from Mongolia and Transbaikalia, T. occultum from East Mongolia, T. virgineum from Ladakh, India, and T. inimitabile from Gobi-Altai, Mongolia. An analysis of syntypes of the names T. dealbatum Hand.-Mazz. and T. sinense Dahlstedt is given. For the safe interpretation of the name T. luridum, epitype was designated. All the species are agamospermous but sexuality and diploidy is documented for a few Transbaikalian plants of the section Leucantha.

5. Dandelions in Central Asia: a revision of Taraxacum section Stenoloba
- Creator:
- Kirschner, Jan and Štěpánek, Jan
- Type:
- article and TEXT
- Subject:
- agamospermy, Altai, Compositae-Lactuceae, China, Mongolia, Siberia, Taraxacum, and taxonomy
- Language:
- English
- Description:
- On the basis of rich material from Asia, a recently described group of dandelions, Taraxacum sect. Stenoloba Kirschner et Štěpánek, is revised taxonomically. Four previously described species are recognized: T. sinomongolicum, newly typified, T. mongoliforme, with a lectotype replacing the original holotype now not extant, and a new epitype, T. scariosum, a new combination of Leontodon scariosus Tausch, replacing the frequently confused names, T. asiaticum, newly typified, and T. stenolobum, and T. multisectum, a taxon for the first time compared with other members of the section. Three new species are described: T. abax occupies a large range from S Siberia and Mongolia to NE China, T. abalienatum and T. odibile are known from Mongolia and SE Siberia. Taraxacum abax and T. abalienatum represent core species of the section Stenoloba, whilst T. odibile exhibits a mixture of characters of sections Stenoloba and Leucantha. All the known members of the section Stenoloba are agamosperms. Taraxacum mongoliforme, T. abax and T. scariosum proved to be triploid with 2n = 24. This account includes detailed descriptions and an identification key.

6. Dandelions in Central Asia: Taraxacum sect. Suavia
- Creator:
- Kirschner, Jan and Štěpánek, Jan
- Type:
- article and TEXT
- Subject:
- agamospermy, the Altai, Kyrgyzstan, Mongolia, Taraxacum, and taxonomy
- Language:
- English
- Description:
- On the basis of the authors’ collections and cultivated material from Asia, a recently described group of dandelions, Taraxacum sect. Suavia, is revised. In addition to three species described previously (T. haneltii, T. sumneviczii and T. formosissimum), six new species from Mongolia and Kyrgyzstan are recognized. Three of them, T. suave, T. stupendum and T. margaritarium, possess most of the features characterizing the section Suavia, one, T. suasorium, is regarded as intermediate between sections Suavia and Leucantha, whilst the remaining two, T. nobile and T. venustius, exhibit some characters of another related section (T. sect. Stenoloba). The members of the section Suavia are agamospermous. Detailed descriptions, drawings and an identification key are given.

7. Differentiation between diploid and tetraploid Centaurea phrygia: mating barriers, morphology and geographic distribution
- Creator:
- Koutecký, Petr, Štěpánek, Jan, and Baďurová, Tereza
- Type:
- article, model:article, and TEXT
- Subject:
- Centaurea sect. Jacea, Centaurea phrygia, Centaurea melanocalathia, flow cytometry, geographic distribution, multivariate morphometric analysis, nomenclature, polyploidy, reproductive isolation, and taxonomy
- Language:
- English
- Description:
- Karyological variation, reproductive isolation, morphological differentiation and geographic distribution of the cytotypes of Centaurea phrygia were investigated in Central Europe. Occurrence of two dominant cytotypes, diploid (2n = 22) and tetraploid (2n = 44), was confirmed and additionally triploid, pentaploid and hexaploid ploidy levels identified using flow cytometry. Allozyme variation as well as morphological and genome size data suggest an autopolyploid origin of the tetraploids. Crossing experiments and flow cytometric screening of mixed populations revealed strong reproductive isolation of the cytotypes. Multivariate morphometric analysis revealed significant differentiation between the cytotypes in several morphological characters (pappus length, length and colour of appendages on involucral bracts, involucre width). The cytotypes have a parapatric distribution with only a small contact zone: diploids occupy the whole of the Central and North European geographic range of the species except for the major part of the Western Carpathians, whereas tetraploids are confined to the Western Carpathians and adjacent areas, both cytotypes co-occurring only in a limited area of intra-montane basins of the Western Carpathians. Based on this array of data, taxonomic treatment of the cytotypes as autonomous species is proposed. The name Centaurea phrygia is applied to the diploids and the name C. erdneri belongs to the tetraploids; nomenclature of hybrids with C. jacea is also resolved.

- Type:
- text and corpus
- Subject:
- tectogrammatics, treebank, parallel corpus, and noisy texts
- Language:
- English and Czech
- Description:
- Syntactic (including deep-syntactic - tectogrammatical) annotation of user-generated noisy sentences. The annotation was made on Czech-English and English-Czech Faust Dev/Test sets. The English data includes manual annotations of English reference translations of Czech source texts. This texts were translated independently by two translators. After some necessary cleanings, 1000 segments were randomly selected for manual annotation. Both the reference translations were annotated, which means 2000 annotated segments in total. The Czech data includes manual annotations of Czech reference translations of English source texts. This texts were translated independently by three translators. After some necessary cleanings, 1000 segments were randomly selected for manual annotation. All three reference translations were annotated, which means 3000 annotated segments in total. Faust is part of PDT-C 1.0 (http://hdl.handle.net/11234/1-3185).
