Abstract: Zanthoxylum nitidum, known as Liang-Mian-Zhen in China, is a traditional Chinese medicinal plant used to treat traumatic injury, rheumatism, paralysis, toothache, stomach ache, and venomous snake bites. Two varieties of the species have been described and three morphological types have been reported within the original variety. However, taxonomic delimitation and molecular markers for distinguishing these varieties and types within this species remain unknown. Since different populations exhibit varying chemical compositions, easy identification of intraspecific taxa is crucial. We collected 420 individuals from 38 natural populations, 3 samples of standard medicinal material, and 17 folk-medicine samples to perform classification and identification within Zanthoxylum nitidum. Four distinct genetic clusters (A, B, C, and D) were highly supported by the nuclear barcode. Two distinct chloroplast clusters (A1 and A2) were further detected within A, and three others had one-to-one correspondence with the remaining nuclear clusters. Molecular identification showed that the 17 folk samples comprised A1, A2, B, and D, while the 3 standard samples belonged to A2. The internal transcribed spacer (ITS) region and rbcL gene are proposed as barcodes for rapid and accurate identification of the different Liang-Mian-Zhen lineages in China. This study highlights the importance of accurate taxonomic delimitation in combination with rapid and accurate molecular identification of medicinal plants.

Haplophyllum ermenekense (Rutaceae), a new species from Turkey https://phytokeys.pensoft.net/article/24241/ PhytoKeys 111: 119-131

DOI: 10.3897/phytokeys.111.24241

Authors: Deniz Ulukuş, Osman Tugay

Abstract: A new species of Haplophyllum, Haplophyllum ermenekense (Rutaceae) is described and illustrated in line drawing. It grows on stony slopes of Ermenek town, Karaman province, in southern Turkey. It is compared with the closely related species H. myrtifolium. H. ermenekense is distinguished from the morphologically similar H myrtifolium chiefly by sepal shape, petal size, capsule size, presence of capsule hair and appendage form. On the other hand, the seed coat and pollen grains surface of H. ermenekense and H. myrtifolium are demonstrated in SEM photographs. In addition to the detailed description, the illustration, distribution map, conservation status and ecology of the new species are also provided.

Reduction of the Hawaiian genus Platydesma into Melicope section Pelea (Rutaceae) and notes on the monophyly of the section https://phytokeys.pensoft.net/article/21363/ PhytoKeys 91: 125-137

DOI: 10.3897/phytokeys.91.21363

Authors: Marc S. Appelhans, Kenneth R. Wood, Warren L. Wagner

Abstract: Platydesma, an endemic genus to the Hawaiian Islands containing four species, has long been considered of obscure origin. Recent molecular phylogenetic studies have unequivocally placed Platydesma within the widespread genus Melicope as sister to the rest of the Hawaiian species of Melicope. This makes submerging Platydesma into Melicope necessary. We make the necessary new combinations: Melicope cornuta (Hillebr.) Appelhans, K.R. Wood & W.L. Wagner, M. cornuta var. decurrens (B.C.Stone) Appelhans, K.R. Wood & W.L. Wagner, M. remyi (Sherff) Appelhans, K.R. Wood & W.L. Wagner, and M. rostrata (Hillebr.) Appelhans, K.R. Wood & W.L. Wagner. An additional species that has been recognized within Platydesma should now be recognized under its original name M. spathulata A. Gray. All Hawaiian species belong to Melicope section Pelea. Our molecular phylogenetic studies also showed that in addition to merging Platydesma into section Pelea, five species described from New Caledonia need to be excluded from the section in order to achieve monophyly of section Pelea.

A new species of Raputia (Rutaceae) from the Selva Central of Peru https://phytokeys.pensoft.net/article/20136/ PhytoKeys 89: 73-84

DOI: 10.3897/phytokeys.89.20136

Authors: Robin Fernandez-Hilario, Robert Arteaga

Abstract: Raputia codo-pozuzoensis Rob. Fernandez & Arteaga, sp. nov. (Galipeinae, Rutaceae), a new species endemic to the Huanuco region, in the Selva Central of Peru, is described and illustrated here. The new species differs from other species of Raputia by the combination of 5–7-foliolate leaves (a new characteristic for the genus) and longer petioles. A key to the four Peruvian species of Raputia is presented.

On the identity of Blanco’s Cissus frutescens and its correct name in Melicope (Rutaceae) with neotypification of Cissus arborea Blanco https://phytokeys.pensoft.net/article/5847/ PhytoKeys 58: 81-85

DOI: 10.3897/phytokeys.58.5847

Authors: Marc Appelhans, Jun Wen

Abstract: The names Cissus frutescens and C. arborea have a long history of confusion. Cissus frutescens Blanco belongs to the genus Melicope (Rutaceae) and we herein correct a nomenclatural mistake made by T.G. Hartley in the revision of Melicope. The name Melicope confusa (Merr.) P.S. Liu was accepted for this taxon by Hartley. However, Cissus frutescens Blanco represents the earliest name for this entity and a new combination, Melicope frutescens (Blanco) Appelhans & J.Wen is herein proposed. Neotypification of Cissus arborea Blanco is also provided.
