Nyctaginaceae are one of the most diverse families in core Caryophyllales. The most diagnostic character of the family is a persistent anthocarp derived from a calyx-like perianth. Anthocarp morphology is highly variable across the family, but its evolution is poorly studied. We investigate anthocarp evolution in Nyctaginaceae through extensive anatomical studies (159 species from 28 genera representing six of seven tribes) and phylogenetic character state reconstructions. We found highly diverse anthocarp anatomy across Nyctaginaceae, with most traits analysed evolving multiple times throughout the family. The representatives of three early-diverging clades of Nyctaginaceae (Leucastereae, Boldoeae and Colignonieae) possess a calyx-like anthocarp with simplified anatomy. The so-called ‘glands’ in Nyctagineae and Pisonieae are emergences, whereas wings originate by accrescence of perianth segments, elongation of the ribs and outgrowths (emergences) of anthocarp mesophyll. Anthocarp anatomy can be considered as a generic-level feature in Colignonieae, Pisonieae, Bougainvilleeae and Nyctagineae. The most dramatic transitions from perianth to anthocarp involve the shrivelling and abscission of the upper perianth part and the maintenance of the basal modified perianth portion that originated in the clade comprising Colignonieae and sister clades.
Zaika MA, Kilian N, Jones K, Krinitsina AA, Nilova MV, Speranskaya AS, Sukhorukov AP (2020) Scorzonera sensu lato (Asteraceae, Cichorieae) – taxonomic reassessment in the light of new molecular phylogenetic and carpological analyses. PhytoKeys 137: 1-85.
Abstract: Scorzonera comprises 180–190 species and belongs to the subtribe Scorzonerinae. Its circumscription has long been the subject of debate and available molecular phylogenetic analyses affirmed the polyphyly of Scorzonera in its wide sense. We provide a re-evaluation of Scorzonera and other related genera, based on carpological (including anatomical) and extended molecular phylogenetic analyses. We present, for the first time, a comprehensive sampling, including Scorzonera in its widest sense and all other genera recognised in the Scorzonerinae. We conducted phylogenetic analyses using Maximum Parsimony, Maximum Likelihood and Bayesian analyses, based on sequences of the nuclear ribosomal ITS and of two plastid markers (partial rbcL and matK) and Maximum Parsimony for reconstructing the carpological character states at ancestral nodes. Achene characters, especially related to pericarp anatomy, such as general topography of the tissue types, disposition of the mechanical tissue and direction of its fibres, presence or absence of air cavities, provide, in certain cases, support for the phylogenetic lineages revealed. Confirming the polyphyly of Scorzonera, we propose a revised classification of the subtribe, accepting the genera Scorzonera (including four major clades: Scorzonera s.str., S. purpurea, S. albicaulis and Podospermum), Gelasia, Lipschitzia gen. nov. (for the Scorzonera divaricata clade), Pseudopodospermum, Pterachaenia (also including Scorzonera codringtonii), Ramaliella gen. nov. (for the S. polyclada clade) and Takhtajaniantha. A key to the revised genera and a characterisation of the genera and major clades are provided.
Sukhorukov AP, Liu P-L, Kushunina M (2019) Taxonomic revision of Chenopodiaceae in Himalaya and Tibet. PhytoKeys 116: 1- 141.
The composition of many Chenopodiaceae genera in different parts of Himalaya and Tibet has been insufficiently known or contradictory. A revision of the family in Himalaya including Bhutan, Nepal, parts of India (Himachal Pradesh, Jammu and Kashmir, Sikkim, and Uttarakhand) and Tibet (Xizang, China) is presented for the first time. Altogether, 57 species from 20 genera are reported, including three species new to science (Agriophyllum tibeticum, Salsola austrotibetica, and Salsola hartmannii). Atriplex centralasiatica, Corispermum dutreuilii,and Salsola monoptera are identified as new records for India, and Chenopodium pamiricum is recorded in China for the first time. Dysphania ambrosioides and Sympegma regelii are recorded for Xizang. The generic and species keys, species distributions (including maps) and taxonomic notes are provided. We indicate for the first time that the presence of short yellow hairs is the remarkable morphological characteristic of the genus Grubovia.Evident heterocarpy and heterospermy is found in Dysphania for the first time (Dysphania tibetica). Agriophyllum pungens, Atriplex crassifolia, Atriplex laciniata, Atriplex sagittata, Axyris amaranthoides, Axyris hybrida, Bassia indica, Corispermum korovinii, Dysphania schraderiana (=Chenopodium foetidum auct.), Halocharis violacea, and Suaeda microsperma are excluded from the species list. Neobotrydium corniculatum is synonymized with Dysphania kitiae, Neobotrydium longii with Dysphania himalaica, and Neobotrydium ornithopodum seems to be conspecific with Dysphania nepalensis. Corispermum ladakhianum is a new synonym of Corispermum tibeticum. Amaranthus diandrus is added to the synonyms of Acroglochin persicarioides, and Bassia fiedleri, previously considered as conspecific with Grubovia dasyphylla, is added to the synonymy of Bassia scoparia. Lectotypes of Anabasis glomerata (≡Halogeton glomeratus), Halogeton tibeticus (=Halogeton glomeratus), Amaranthus diandrus (=Acroglochin persicarioides), Chenopodium tibeticum (≡Dysphania tibetica), Corispermum dutreuilii, Corispermum falcatum, Corispermum lhasaense, Corispermum pamiricum var. pilocarpum (=Corispermum gelidum, syn. nov.), Corispermum tibeticum, Kochia indica (≡Bassia indica), Kochia odontoptera (≡Bassia odontoptera) and Salsola monoptera are selected. Out of 53 native elements, 42 are restricted in their distribution to Himalaya and Tibet at altitudes 2000–4500 m above sea level. The greatest taxonomic diversity of the Chenopodiaceae is represented in Jammu and Kashmir (India) and Xizang (China) with a continuous decrease in the number of species southwards.

The genus Paramollugo with the type species Paramollugo nudicaulis (≡Mollugo nudicaulis) has recently been described after molecular investigations. Here we report two new endemic Malagasy species: Paramollugo simulans and P. elliotii, and transfer a forgotten New Caledonian endemic Mollugo digyna to Paramollugo (P. digyna). Consequently, the number of Paramollugo species in the Eastern Hemisphere is increased from three to six. Almost all genus representatives (except P. nudicaulis, which has a wide distribution in Southern Asia, Arabia and tropical Africa) are endemic to Madagascar, Somalia, or New Caledonia. Since the type of seed coat ornamentation is crucial for species delimitation, a diagnostic key with new taxonomically significant carpological characters and other new traits is provided for all the herbaceous Paramollugo. The distribution patterns of P. nudicaulis s.str., P. simulans and P. elliotii are presented.

Two new combinations are published here after establishment of the new generic classification of Molluginaceae based on molecular phylogeny (Thulin et al., 2016). Mollugo pentaphylla L. var. rupestris T.Cooke from Western Ghats (India) is raised to the rank of species within the genus Trigastrotheca F.Muell. (T. rupestris (T.Cooke) Sukhor.). Mollugo pentaphylla var. rupestris is lectotypified. All investigated Caribbean specimens of Paramollugo nudicaulis (Lam.) Thulin (previously Mollugo nudicaulis Lam.) differ from the Old World specimens in seed coat ornamentation, and therefore we assume that P. nudicaulis s.str. is absent in the Caribbean region. Pharnaceum spathulatum Sw., described from the West Indies and previously synonymized with Mollugo nudicaulis Lam. or Paramollugo nudicaulis, is a basionym for the new combination within Paramollugo (P. spathulata (Swartz) Sukhor.). A list of synonyms of P. spathulata including Paramollugo navassensis (Ekman) Thulin and Mollugo bellidifolia (Poir.) Ser. is provided.

After a detailed investigation of original material concerning Chenopodium pallidum Moquin-Tandon (1840: 30), which is a part of Jacquemont’s collection from India (Herbarium P), we can state that all these specimens indeed belong to Atriplex Linnaeus (1753: 1052). The “Eastern India” (Fr.: “Indes Orientales” after Jacquemont, 1834), where the plants were collected, applies to the territories of present-day West Bengal, Uttar Pradesh, Delhi, Rajasthan (northern part), Uttarakhand, Himachal Pradesh, Jammu & Kashmir, Punjab (India, Pakistan), and bordering parts of Xizang (China). The plants known as A. schugnanica are the best match to the Jacquemont’s specimens due to aphyllous or bracteose (not leafy) inflorescence. According to Art. 11 of ICN (McNeill et al. 2012), the name Chenopodium pallidum appears to be an older name at specific rank for Atriplex schugnanica Iljin (1936: 123), and thus a new combination is proposed in the present paper. Atriplex pallida (Moq.) Sukhor. is present in Northern India (Jammu & Kashmir, Uttarakhand states). Besides, new Chenopodium species (C. harae), previously named Chenopodium pallidum, is described from Nepal, with further evident records for adjacent Indian states.
