Abstract

Lectotypes are designated here for the following nine validly published names: Jasminum alongense, J. anodontum, J. eberhardtii, J. harmandianum, J. lang, J. laxiflorum, J. pierreanum, J. rufohirtum, and J. sinense. Jasminum lang is reinstated as a distinct species.

2. Plastome analysis unveils Inverted Repeat (IR) expansion and positive selection in Sea Lavenders (Limonium, Plumbaginaceae, Limonioideae, Limonieae)

Abstract

The genus Limonium, commonly known as Sea Lavenders, is one of the most species-rich genera of the family Plumbaginaceae. In this study, two new plastomes for the genus Limonium, viz. L. tetragonum and L. bicolor, were sequenced and compared to available Limonium plastomes, viz. L. aureum and L. tenellum, to understand the gene content and structural variations within the family. The loss of the rpl16 intron and pseudogenisation of rpl23 was observed. This study reports, for the first time, expansion of the IRs to include the ycf1 gene in Limonium plastomes, incongruent with previous studies. Two positively selected genes, viz. ndhF and ycf2, were identified. Furthermore, putative barcodes are proposed for the genus, based on the nucleotide diversity of four Limonium plastomes.

Botany, QK1-989
Abstract

Capparis kbangensis Sy & D.V. Hai, a new species from Kbang District, Gia Lai Province, Vietnam, is described and illustrated. The new species is morphologically similar to Capparis versicolor but differs by several characters such as emarginate leaf apex, hairy margin of sepals, smaller fruits, and fewer seeds per fruit. Its ecology and conservation status are provided along with a taxonomic key to the closely allied species.
