Molecular Phylogeny and Cryptic Morphology: A Combined Approach to Taxonomic Novelties inPolycarpaea(Caryophyllaceae) from Vietnam

“…As in previous analyses of the reproductive morphological characteristics of the genus Polycarpaea in Vietnam, Gagnepain [6,7] terminal, compound cyme sparsely with a 3.0-5.0 cm long; bracts paired, scarious, triangle, apex apiculate to attenuate, fimbriate along the margins, bifid or slightly bifid, white, ca. 1.5-1.6 mm long, 0.8-1.5 mm wide.…”

“…Vegetative parts and flowers were observed under a light microscope and color photographs were taken with a camera. Based on field investigation and specimen examination, all vegetative and reproductive characters of the plant material were checked taxonomic key and descriptions of Polycarpaea , which were provided from Vietnam [6, 7], [2]; from China [3]; from Malaysia [8]. The features of the new species were verified by consulting herbarium specimens at Herbaria (HN, VMN, IBSC, K, KUN, and P).…”

“…The features of the new species were verified by consulting herbarium specimens at Herbaria (HN, VMN, IBSC, K, KUN, and P). Botanical terminology of the description was followed by Gagnepain [6, 7], Bakker [8], Ho [2], Cowie [9], and Arya [11, 12].…”

“…It is widely known, and aspects of its morphological characters are often considered to be diagnostic for an herbaceous annual or herbaceous perennial in habit. Notable plants belonging to Polycarpaea have very similar vegetative and reproductive characteristics, such as dichotomously branched herbs, sometimes woody at the base, leaves opposite and often with developed axillary buds, which give the presence of whorls, stipules scarious, inflorescences a cyme, terminal provided with scarious bracts, sepals scarious, petals structurally similar to the sepals, stamens 5, style simple, stigma punctate to globular, capsule 3-valved [6, 7, 8, 9, 10, 11, 12]. However, the characters used for the most common classification of Polycarpaea are based on characteristics of the stipules, petals, sepals, ovaries, and fruits.…”

A New Combination in Polygala (Polygalaceae) for Southeast Asia

“…The use of the name P. ciliata was mistaken because that name correctly refers to a quite different taxon which had already been transferred to Salomonia by De Candolle (1824) as S. ciliata (L.) DC. Gagnepain (1909) treated Poly gala ciliata sensu Wight as consisting of three varieties. Variety typica has the syntypes Wallich 4177 and Thomson s.n.…”
