No. 1  Jian Li, Xin Hong, Fang Wen & Li-Jiao Yan: Primulina pseudoroseoalba (Gesneriaceae), a new species from a karst cave in Guangxi, China

Ann. Bot. Fennici 51: 86–89.

ABSTRACT

Primulina pseudoroseoalba Jian Li, F. Wen & L.J. Yan , a new species of Gesneriaceae from China, is described and illustrated. It is morphologically similar to P. roseoalba, but differs in the leaf blade being broadly ovate to elliptic, and its margin entire and abaxially glabrous; peduncle bing much shortere; and bracts being ovate to orbicular-ovate, glabrous inside. P. pseudoroseoalba J is rare and currently known only from a karst hill in Guangxi, China.

Systematic Botany 39(3): 965–974.

ABSTRACT

Based on morphological and molecular data, three new species of the Old World Didymocarpoid Gesneriaceae, Petrocodon laxicymosus, P. longgangensis and P. pseudocoriaceifolius, are described and illustrated from Guangxi, China. The three new species are most similar to P.  coriaceifolius, differing by their texture, size, and shape of leaves, size and pubescence of inflorescence and corolla, anther shape, and pistil length. Additionally, Primulina guangxiensis, one of two species included in Primulina before its recent recircumscription, was unexpectedly found to be nested within Petrocodon in our ongoing phylogenetic analyses, prompting us to make the new combination Petrocodon guangxiensis. The four species of Petrocodon treated here are all rare, known only from a single or a few localities of limestone karsts in Guangxi.

Phylogenetic placements of Petrocodon laxicymosus, P. longgangensis, P. pseudocoriaceifolius, and Primulina guangxiensis are highlighted. Bootstrap values (LB/PB) greater than 50% are shown. Thick lines denote a strongly supported clade with LB and/or PB greater than 95%. Dashed lines indicate clades collapsed in the majority rule consensus tree of MP analyses. B.

Jiangxi Forestry Science and Technology 42(1): 37–38.

ABSTRACT  Three newly recorded species of Primulina (Gesneriaceae) from Jiangxi province, represented by P. xiuningensis (X.L. Liu & X.H. Guo) Mich. Möller & A. Weber, P. danxiaensis (W.B. Liao, S.S. Lin & R.J.Shen) W.B.Liao & K.F.Chung and P. depressa (Hook. f.) Mich. Möller & A. Weber were reported.  P. xiuningensis was collected from Wuyuan county of Jiangxi province; P. danxiaensis was collected from Xingguo county and Ningdu county of Jiangxi province; P. depressa was collected from Dishuiyan of Guangfeng county of Jiangxi province.
