Nomenclatural and taxonomic notes on two eastern taxa of the <Emphasis Type="Italic">Primula auricula</Emphasis> complex

Discrepancies and errors in the taxonomic and nomenclatural treatment of Primula auricula complex by Zhang (2002) and Zhang & Kadereit (2004, 2005) are discussed. Investigation of a few hundred P. auricula specimens stored in BP yielded contradictory morphological results compared with those of the above authors. In contrast with the key proposed by them specimens (BP) from Mt Domogledu (Romania) have short, while those from the north Carpathians (Slovakia) have relatively long glandular hairs on the leafmargins. Lectotypes of P. auricula var. serratifolia Rochel ex Borbás and P. auricula var. hungarica Borbás are designated. Nomenclatural errors made by Zhang and Kadereit are corrected, and it is emphasized that the name P. lutea ssp. tatriaca applied for Slovak populations by them is superfluous. Further researches are needed to clarify the taxonomic position of Slovak and Romanian P. auricula populations. Morphological characters considered as distinctive and relevant by Zhang and Kadereit seem to be dependent on the phenological state of plants.

On the taxonomy of Phlegmariurus (Herter) Holub sect. Huperzioides H. S. Kung et L. B. Zhang (sect. nov.) with notes on the infrageneric classification of the genus Phlegmariurus in China

After the genus Phlegmariurus (Herter)Holub was proposed by J. Holub 1964, the repercussions are different, with some botanists accepting it, while others refusing. We take it as a separate genus since the related species from China are distinctly different from those of Huperzia Bernh. The plants of this genus in China are classified into three sections: Sect. Huperzioides H. S. Kung et L. B. Zhang, sect. nov.; Sect. Carinaturus (Herter)H. S. Kung et L. B. Zhang, comb. nov. and Sect. Phlegmariurus. A key to sections is given. The taxonomy on the new section, Sect. Huperzioides, is presented. Thirteen species are reported in China, involving 4 new combinations: Ph. petiolatus (Clarke)H. S. Kung et L. B. Zhang, Ph. cryptomerianus (Maxim.)Ching, Ph. ovatifolius (Ching)W. M. Chu, Ph. nylamensis (Ching et S. K. Wu)H. S. Kung et L. B. Zhang; and 7 names are considered for the first time as synonyms: Huperzia formosana Holub [ = Ph. taiwanensis Ching ], H. austrosinica Ching [ = Ph. petiolatus ], Lycopodium mingchgense Ching [ = Ph. mincheensis Ching ], Ph. mincheensis var. angustifolius C. Y. Ma [ = Ph. mincheensis ], Ph. longyangensis C. Y. Ma [ = Ph. fordii ], Ph. nanus C. Y. Ma [ ＝ Ph. fordii ], Ph. yandongensis Ching et C. F. Zhang [ ＝ Ph.fordii]. One new record in China is found: Ph.hamiltonii.

Studies on the Genus Schizopepon Maxim. (Cucurbitaceae)

The classical and numerical taxonomy, palynology and the geographical distribution of the Genus Schizopepon are dealt with in the present paper. Having commented on various opinions regarding the systematic position of the genus, the present authors consider that C. Jeffrey’s treatment of Schizopepon as a new and monogeneric tribe, Schizopeponeae, should be supported. The gross morphological characters in the genus are assessed from the taxonomic point of view. Some characters, such as stamens with an elongated connective or not, different insertions of ovules and various forms of ovaries and fruits, may be used for distinguishing subgenera. The pollen grains of all the species were observed under light microscope (LM) and scanning electron microscope (SEM). The results show that a strong differentiation has taken place in the pollen of the genus, and in consequence it may be regarded as an important basis for dividing subgenera and species. Especially it should be pointed out that degrees of development of colpi and positions of ora are positively correlated with the external characters used for distinguishing subgenera. According to the morphological and palynological characters, the genus Schizopepon may be divided into three subgenera and eight species: 1. Subgenus Schizopepon: 5 species, S. bryoniaefolius Maxim., S. monoicus A. M. Lu et Z. Y. Zhang, S. dioicus Cogn., S. longipes Gagnep. and S. macranthus Hand.-Mazz.; 2. Subgenus Rhynchocarpos A. M. Lu et Z. Y. Zhang: 1 species, S. bomiensis A. M. Lu et Z. Y. Zhang; 3. Subgenus Neoschizopepon A. M. Lu et Z. Y. Zhang: 2 species, S. bicirrhosus (C. B. Clarke) C. Jeffrey and S. xizangensis A. M. Lu et Z. Y. Zhang. The 8 OTU’s including all the species of this genus and 31 characters, of which 16 are morphological characters and 15 palynological characters, were used in the numerical taxonomic treatment. After standardization of characters, the correlation and distance matrices were computed. The correlation matrices are made to test the various clustering methods. At last, the UPGMA clustering method was selected and its result is shown in the form of phenogram. The result of numerical analysis is similar to that of the classical classification. Schizopepon Maxim. is a genus of East Asia-Himalayan distribution. China has all 8 species and 2 varieties, of which 6 species are endemic. Based on the statistics of spedies number, the distribution centre of the genus is considered to be in the Hengduan Mountains (Yangtze-Mekong-Salwin water divides) and the adjacent areas of the southwest China.
