Merger of Betula tatewakiana (Betulaceae) from northern Japan with northeast Asian B. ovalifolia based on ploidy level PhytoKeys (IF 1.225) Pub Date : 2020-12-23 Yuki Shiotani; Tomoko Fukuda; Elena A. Marchuk; Ekaterina A. Petrunenko; Pavel V. Krestov; Svetlana N. Bondarchuk; Yoko Nishikawa; Takashi Shimamura; Yoshiyasu Fujimura; Koh Nakamura
It has been controversial whether Betula tatewakiana, a dwarf birch distributed in Hokkaido of northern Japan, is an endemic species or a synonym of B. ovalifolia broadly distributed in northeast Asia. The endemic hypothesis is based on the idea that B. tatewakiana is diploid while B. ovalifolia is tetraploid and that they are separated based on the ploidy level; however, no chromosome data have actually

Typifications in neotropical Sapotaceae PhytoKeys (IF 1.225) Pub Date : 2020-12-21 Anderson Alves-Araújo; Quélita dos Santos Moraes; Renara Nichio-Amaral; Victor Santos Miranda
Sapotaceae is historically known as having a tricky and challenging taxonomy due to tangled morphologic heterogeneity. Consequently, this resulted in a large number of described genera and binomials. After Pennington’s Flora Neotropica work, several of those nomenclature issues were resolved. Nevertheless, many binomials remain unsolved and up for typification. Thus, following the International Code

Typification of Juniperus pingii W.C.Cheng (Cupressaceae) PhytoKeys (IF 1.225) Pub Date : 2020-12-10 Yong Yang; Jean Hoch
W.C.Cheng validly published the name Juniperus pingii W.C.Cheng in 1944 by providing a validating Latin diagnosis in de Ferré (1944), but he failed to cite any specimen. He repeated the publication of the name in 1947 with the same Latin diagnosis; he thus published an isonym “J. pingii” under Art. 6 Note 2. Cheng (1947) lectotypified the name J. pingii when he designated W.C.Cheng 1015 as the “type”

The segetal flora of Italy: an occurrence dataset from relevés in winter cereals and allied crop types PhytoKeys (IF 1.225) Pub Date : 2020-10-02 Emanuele Fanfarillo; Marta Latini; Mauro Iberite; Giovanna Abbate
The segetal flora of winter crops includes mostly native or archaeophyte annual species that are often strong specialists of their habitats. Threatened by the intensification of agriculture, segetal flora is particularly valuable from a perspective of biodiversity conservation and evolution. Moreover, it contributes to maintain biodiversity in agroecosystems and provides several ecosystem services

Diplodiscus latifii (Malvaceae-Brownlowioideae), a new species from Sabah, Malaysia PhytoKeys (IF 1.225) Pub Date : 2020-10-02 Richard Cheng Kong Chung; Engkik Soepadmo
A new species of Diplodiscus is described and illustrated from one collection made in lowland mixed dipterocarp forest in Sabah, Malaysia. Conspicuous by its twig colour, leaf shape and indumentum, it is probably allied to D. longifolius, but differs in sufficient characters (shape, indumentum, apex and venation of blade, flower bud shape and size, petal diameter, ovary shape and fruit shape and size)

Astilbe uljinensis (Saxifragaceae), a new species from South Korea PhytoKeys (IF 1.225) Pub Date : 2020-09-29 Ami Oh; Sea-Hee Han; Byoung-Un Oh
A new species Astilbe uljinensis B.U.Oh & H.J.Choi is described from Gangwon-do and Kyeongsangbuk-do in South Korea based on its morphological characteristics and distributional pattern. A. uljinensis is easily distinguished not only from three other Astilbe species in South Korea, but all other species in the genus by possessing a green young rachis, dense long whitish glandular hairs on the young

On the Leucanthemopsis alpina (L.) Heywood growing in the Illyrian region PhytoKeys (IF 1.225) Pub Date : 2020-09-15 Salvatore Tomasello; Kamil Konowalik
Leucanthemopsis alpina (L.) Heywood (Asteraceae, Anthemideae) is a small, caespitose plant growing in high alpine environments in all the main southern European mountain ranges. However, the species status in the Balkan Peninsula (and especially in the Dinaric Alps) is not very well known. Surrounding this area, different L. alpina subspecies are found in the Eastern Alps and in the Carpathians. These

Cluster analysis of karyotype similarity coefficients in Epimedium (Berberidaceae): insights in the systematics and evolution PhytoKeys (IF 1.225) Pub Date : 2020-09-15 Lin-Jiao Wang; Meng-Di Gao; Mao-Yin Sheng; Jie Yin
In order to evaluate the genome evolution and systematics, karyotype analysis of mitotic metaphase chromosomes in 51 taxa of Epimedium and two species of Vancouveria was conducted. The 53 taxa were clustered, based on their karyotype similarity coefficients. Results showed that the 53 taxa studied were all diploid with 12 chromosomes (2n = 2x = 12). Each taxon had one pair of satellites located on

Rediscovery of Angiopteris tonkinensis (Marattiaceae) after 100 years, and its revision PhytoKeys (IF 1.225) Pub Date : 2020-09-15 Ting Wang; Bo Xiao; En-De Liu; Khang Sinh Nguyen; Jie-Qiu Duan; Kang-Lin Wang; Yue-Hong Yan; Jian-Ying Xiang
The border area between south-eastern Yunnan, China and northern Vietnam is one of the regions with richest biological diversity including that of the fern genus Angiopteris (Marattiaceae). Based on the analysis of morphology and DNA sequences of multiple chloroplast regions (atpB, rbcL, rps4-trnS spacer and trnL-F spacer), we revised Angiopteris tonkinensis (Hayata) J.M.Camus and proposed a new combination

A new taxon within Biscutella laevigata L. (Brassicaceae) endemic to calamine areas in southern Poland PhytoKeys (IF 1.225) Pub Date : 2020-09-08 Małgorzata Wierzbicka; Maria Pielichowska; Olga Bemowska-Kałabun; Adam Rostański; Paweł Wąsowicz
A new taxon Biscutella laevigata subsp. woycickii (Brassicaceae) is described from southern Poland. The taxon is similar to B. laevigata subsp. gracilis, but differs in having thin, light-green rosette leaves very densely covered by simple non-glandular trichomes, smaller seeds and the ability to tolerate and accumulate high amounts of heavy metals. This new taxon is supported by results of cultivation
