The emergent macrophyte Montrichardia linifera (Arruda) Schott (Alismatales: Araceae), a rekindled old friend from the Pacific Slope of lower Central America and western Colombia Nord. J. Bot. (IF 0.734) Pub Date : 2020-09-10 Orlando O. Ortiz, Alicia Ibáñez, Edwin Trujillo‐Trujillo, Thomas B. Croat
The genus Montrichardia are among the most remarkable emergent macrophytes in tropical wetlands. It occurs exclusively in the Neotropics and contains two living species, M. linifera (Arruda) Schott and M. arborescens (L.) Schott. Montrichardia linifera has been reported mainly in the Amazon basin (southern Venezuela to Guyana, Brazil, Ecuador and Peru), whereas M. arborescens occurs in Central America

Genetic diversity and population structure of an invasive plant species differ in two non‐native regions with differing climate and invasion success Nord. J. Bot. (IF 0.734) Pub Date : 2020-09-02 Tanvir‐Ul‐Hassan Dar, Basharat Ahmed Bhat, Anzar Ahmad Khuroo, Sushil Verma, Shahid Ul Islam
One of the fundamental questions in invasion biology is why an alien species successfully invades one region but fails to do so in another region. In this regard, the recently emerging molecular ecology tools have made it possible to understand the genetic basis of invasion success and/or failure of alien species in different regions. Here we report the results of studies of the population genetic

Palmorchis triquilhada sp. nov. (Orchidaceae; Neottieae) from the Brazilian Amazon Nord. J. Bot. (IF 0.734) Pub Date : 2020-08-23 Ricardo Leite Ferreira Filho, Felipe Fajardo Villela Antolin Barberena
The Neotropical genus Palmorchis (Orchidaceae) contains 38 species distributed from Nicaragua to Peru, including northern Brazil. The genus is characterized by whitish or greenish tubular flowers with morphologically similar sepals and petals, a generally trilobed lip basally adnated to the gynostemium, and a gynostemium with a more or less curved apex. Here, a new species of Palmorchis belonging to

Continuous petal variation in Epimedium tianmenshanense (Berberidaceae), a taxon endemic to western Hunan, China Nord. J. Bot. (IF 0.734) Pub Date : 2020-08-18 Yanqin Xu, Hua Huang, Yong Jiang, Yiming He, Renqing Li, Xiaofang Huang
In the protologue, Epimedium tianmenshanense (Berberidaceae), a species endemic to western Hunan, China, was described as ‘flower small, 0.2–0.4 cm diam., inner sepals white, petals as long as inner sepals or a little shorter than the latter, spur very short, ca 5.0 mm’. However, both morphological characteristics and molecular evidence suggest that E. tianmenshanense is closely related to E. baojingense

Nutlet morphology in the tribe Elsholtzieae (Lamiaceae) Nord. J. Bot. (IF 0.734) Pub Date : 2020-08-18 Yun‐Chang Jeon, Tae‐Soo Jang, Suk‐Pyo Hong
A comprehensive study on nutlet morphology on 46 taxa from the tribe Elsholtzieae was conducted using stereomicroscopy, light microscopy and scanning electron microscopy. The objectives were to evaluate the nutlet characteristics in a systematics context and to provide additional evidence for taxon delimitation. The nutlet shape varied from elliptical, widely elliptical, spheroidal and ovate to pyriform

Oreocharis argentifolia (Gesneriaceae), a new species from the karst region in southeastern Yunnan, China Nord. J. Bot. (IF 0.734) Pub Date : 2020-08-18 Lei Cai, Zhi‐Ling Dao
A new species of Gesneriaceae, Oreocharis argentifolia Lei Cai & Z.L.Dao from Mengzi City, Yunnan Province, China, is described and illustrated. The new species is morphologically most similar to O. panzhouensis Lei Cai, Y.Guo & F.Wen in plant habit, number of stigma lobes and stamens, and the shape of the calyx, but differs in the shape of the leaf blade, indumentum, shape and color of corolla and

Nomenclatural notes and typification of names in the mangrove tribe Rhizophoreae (Rhizophoraceae) of India Nord. J. Bot. (IF 0.734) Pub Date : 2020-08-18 Saikat Naskar
The nomenclatures of the taxa of the mangrove Rhizophoraceae of India have been scrutinized and 20 names are lectotypified or neotypified. In addition, the holotypes of some names are located for the first time with clarifications provided. Since natural hybridization is common in Rhizophoraceae, its consequences for the correct application of names is also briefly discussed.

Bredia reniformis (Melastomataceae), a new species from Guangxi, China Nord. J. Bot. (IF 0.734) Pub Date : 2020-08-18 Chun‐Mei He, Si‐Jin Zeng, Shu‐Wan Li, Yi‐Hua Tong
Bredia reniformis, a new species of Melastomataceae from Guangxi, China, is described and illustrated. Bredia reniformis is similar to B. plagiopetala (C. Chen) R. C. Zhou & Ying Liu and B. gracilis (Hand.‐Mazz.) Diels by having axillary inflorescences and flowers with eight isomorphic stamens, but differs from the latter two in having glandular‐puberulous indumentum, reniform calyx lobes and shortly

Impatiens bomiensis (Balsaminaceae), a new species from Xizang, China Nord. J. Bot. (IF 0.734) Pub Date : 2020-08-18 Yang‐Cheng Peng, Shuai Peng, Ning Yang, Zhi‐Gao Xu, Yi‐Yan Cong
Impatiens bomiensis, a new species of Balsaminaceae from Bomi County, Xizang, China, is described and illustrated. This new species is similar to Impatiens fragicolor based on morphological characters and molecular data, but differs in the shape of the lower sepal, the dorsal petal and the number of globose glands at petiole base.

Dichorisandra forzzae sp. nov. (Commelinaceae) from Espírito Santo State, Brazil, with notes on the Dichorisandra acaulis group Nord. J. Bot. (IF 0.734) Pub Date : 2020-08-18 Quélita S. Moraes, Marco O. O. Pellegrini, Anderson Alves‐Araújo
The Dichorisandra acaulis group has its circumscription broadened to include two additional species, viz. D. oxypetala and the herein newly described D. forzzae. Dichorisandra oxypetala has previously not been included in this morphological group due to its deviant vegetative morphology. However, its reproductive morphology is congruent with the D. acaulis group and, thus, it is here included as a

Key to the determination of taxa of Lemnaceae: an update Nord. J. Bot. (IF 0.734) Pub Date : 2020-08-13 Manuela Bog, Klaus J. Appenroth, K. Sowjanya Sree
Species of Lemnaceae have a high potential for fast biomass production, and this is increasingly gaining attention among researchers in basic plant sciences as well as among entrepreneurs for feed, food and energy production. Hence, the correct identification of the species being used for different duckweed research and applications is becoming indispensable. Here, we present an updated identification
