ABSTRACT A new species of Gymnosiphon Blume (Burmanniaceae), G. mayottensis Cheek, sp. nov. is formally described from Mount Bénara and Mount Mtsapéré on the island of Mayotte in the Comores. This is the first named species of the genus published from the Comoro Islands. The new species resembles G. longistylus (Benth.) Hutch. in the six long, filamentous, stigma appendages, two arising from each of the three styles, also in the absence of an underground tuber or thickened rhizome; it differs in that the bracts are appressed to the rhachises, and about equal in length to them (not patent, and < ¼ as long), the outer tepals turn rapidly from white to translucent at anthesis (not remaining white), the inner perianth lobes are absent (not present and conspicuous), the stigmas are broader than long, held horizontally and are united along their lateral margins (not longer than broad, pendulous, free from each other along their lateral margins). The new species is known from two forest sites, both with threats, and less than 50 individuals are known. Accordingly, it is assessed as Critically Endangered (B1ab(i-iv), B2ab(i-iv), D) using the IUCN 2012 standard. The new species is illustrated by colour photos and line drawings, and mapped.

ABSTRACT Gossia N. Snow & Guymer from New Caledonia as revised here comprises 30 taxa. Nine new species are proposed, including: Gossia angustifolia sp. nov., G. bourailensis N. Snow, sp. nov., G. conduplicata sp. nov., G. kaalaensis sp. nov., G. katepahiensis sp. nov., G. mandjeliaensis sp. nov., G. ngaensis sp. nov., G. ouazangouensis, and G. ramiflora sp. nov. Ten new subspecies are proposed: two in Gossia aphthosa (Vieill. ex Brongn. & Gris) (G. a. subsp. longipedunculata N. Snow & Munzinger, subsp. nov. and subsp. austro-orientalis N. Snow & K. Gandhi, subsp. nov.), and eight in Gossia clusioides (Brongn. & Gris) N. Snow (G. c. subsp. avanguiensis subsp. nov., G. c. subsp. bleuensis subsp. nov., G. c. subsp. callmanderiana subsp. nov., G. c. subsp. maoyana subsp. nov., G. c. subsp. ploumensis N. Snow, comb. et stat. nov., G. c. subsp. rembaiensis subsp. nov., G. c. subsp. taomensis subsp. nov., and G. c. subsp. tiebaghiensis subsp. nov. The new combination Gossia conspicua (Vieill. ex Guillaumin) N. Snow, comb. nov. is made; a second-stage lectotype and epitype are selected for Gossia diversifolia (basionym Eugenia diversifolia Brongn. & Gris); a lectotype is selected for Eugenia heckelii Pancher & Sebert, which here is reduced to synonymy under G. vieillardii (Brongn. & Gris) N. Snow; and a lectotype is selected for Eugenia cataractarum Guillaumin, which here is reduced to synonymy under G. kuakuensis (Baker f.) N. Snow. Myrtus pulchrefolius Guillaumin is reduced to synonymy under Gossia alaternoides. The Australian species Gossia byrnesii N. Snow & Guymer is synonymized under Eugenia reinwardtiana DC. The treatment provides a key to and descriptions of all known New Caledonian taxa and includes comments on distributions, distribution maps, ecology and phenology. Illustrations are provided for nearly all taxa and digital images of living material are presented for several. With this revision, Gossia now comprises 45 species and ten subspecies.

RÉSUMÉ Une espèce nouvelle appartenant à la famille des Rubiaceae, Psychotria niauensis Butaud & J.Florence, sp. nov., est décrite de l'atoll soulevé de Niau dans l'archipel des Tuamotu en Polynésie française. Morphologiquement isolée en Polynésie française, cette nouvelle espèce se rapproche de P. leiophylla Merr. & L.M. Perry de la Mélanésie et de la Polynésie occidentale, espèce convergente dans sa morphologie avec plusieurs Psychotria L. récemment transférés dans le genre Eumachia DC. Une analyse des caractères diagnostiques séparant les deux genres a confirmé leur appartenance au genre Psychotria, en raison de leurs fruits de couleur rose, pourpre ou violet, de l'existence d'un pore apical dans le pyrène lisse et de la présence d'un pigment tégumentaire soluble à l'éthanol. Psychotria niauensis sp. nov. se distingue de P. leiophylla par ses inflorescences à pédoncule primaire plus long dépassant 3,5 cm de longueur, des pyrènes ovoïdes (vs. subellipsoïdaux à subglobuleux) et plus petits de 3 mm de diamètre et enfin, des pétioles plus courts inférieurs à 1 cm. Elle se distingue de toutes les autres espèces de Polynésie orientale par la présence d'inflorescences comportant plus de 50 fleurs, par ses fleurs de moins de 7 mm de diamètre, par ses fruits violets à maturité, par ses pyrènes lisses sur la face dorsale et par son écologie particulière puisque se développant sur substrat calcaire. Seule représentante du genre aux Tuamotu, connue par moins de 80 pieds et menacée notamment par l'urbanisation à proximité de sa population principale, cette espèce est considérée comme «En danger» [EN] selon les critères de l'UICN.

ABSTRACT Cinnadenia Kosterm. (Lauraceae) consists of three species, namely, C. paniculata (Hook.f.) Kosterm. which occurs in India and Bhutan, C. liyuyingii (H.Liu) de Kok & Sengun, comb. nov. from Northern Vietnam and South China and C. malayana Kosterm. which is endemic to Peninsular Malaysia. All species are rarely collected and consequently Cinnadenia is a poorly known genus. The genus is revised here with a summary of its taxonomic history, key, full descriptions, distribution map, conservation assessments, ecological data, and a delineation of its key morphology. Cinnadenia liyuyingii, comb. nov. which was previously placed in Litsea or as a synonym of C. paniculata, is moved here to Cinnadenia for the first time.

ABSTRACT The occurrence of Echinops siculus Strobl, previously considered endemic to Italy, is for the first time reported from the Balkan Peninsula based on plants collected in Corfu (Greece). Morphological similarities with other taxa of Echinops L. recorded in Greece are briefly discussed. Presence of Echinops albidus Boiss. & Spruner is excluded from Italy, E. spinosissimus Turra subsp. neumayeri (Vis.) Kožuharov is confirmed for Albania. Further notes concerning the occurrence of these three species on the Ionian Islands are provided. The names of the three taxa are lectotypified.

ABSTRACT Scilla hakkariensis, sp. nov. (Asparagaceae), described herein as a new species to science, is endemic to the eastern Anatolian region of Turkey. It is related to S. libanotica Speta and S. mischtschenkoana Grossh., but clearly differs from them based on the morphological differences presented in the species description. Specifically, it is easily distinguished from both of them by its seeds without elaiosome. In addition, the conservation status, a distribution map, and notes on the biogeography and ecology of the new species are given.

ABSTRACT We recognize 30 species of the pantropical genus Xylopia L. from Madagascar and an additional three species from the Mascarene Islands. Of the six sections of the genus, three are represented in the region: sect. Xylopia, sect. Verdcourtia, and sect. Stenoxylopia. All species are endemic, and many are microendemics of conservation concern. The greatest species richness occurs in humid forests below 1000 m. Taxonomic review supports the hypothesis that the genus dispersed to Madagascar from continental Africa five times. Ten new species are described: Xylopia anomala D.M.Johnson & N.A.Murray, sp. nov., X. australis D.M.Johnson & N.A.Murray, sp. nov., X. carinata D.M.Johnson & N.A.Murray, sp. nov., X. galokothamna D.M.Johnson & N.A.Murray, sp. nov., X. lokobensis D.M.Johnson & N.A.Murray, sp. nov., X. longirostra D.M.Johnson & N.A.Murray, sp. nov., X. marojejyana D.M.Johnson & N.A.Murray, sp. nov., X. ravelonarivoi D.M.Johnson & N.A.Murray, sp. nov., X. retusa D.M.Johnson & N.A.Murray, sp. nov., and X. sclerophylla D.M.Johnson & N.A.Murray, sp. nov. An identification key, technical descriptions, illustrations, and distribution maps are provided.

A large colony of duckweeds (Araceae: Lemnoideae) grows on the constantly wet, vertical wall of the rock shelter behind the Llanos de Cortes waterfall of the Potrero River, Guanacaste province, Costa Rica, the first such case ever documented. Its unique hygropetric environment is described. The colony covers several square meters distributed in several different patches, and consists almost entirely of Wolffiella oblonga (Phil.) Hegelm., with much fewer individuals of Lemna valdiviana Phil. and L. aequinoctialis Welw. This also constitutes the first case of the genus Wolffiella Hegelm. growing in a hygropetric manner (an extremely rare condition for duckweeds) and the first record of W. oblonga in Costa Rica.
一大片浮萍(天南星科:浮萍科)生长在哥斯达黎加瓜纳卡斯特省波特雷罗河上的Llanos de Cortes瀑布后面的岩石掩蔽处的不断潮湿的垂直墙壁上，这是有史以来第一个有记录的案例。描述了其独特的湿环境。这个群落占地几平方米，分布在几个不同的斑块上，几乎完全由长尾狼菌(Wolffiella oblonga)组成。Hegelm。在美国，lena valdiviana Phil的个体要少得多。和水蛭。这也构成了Wolffiella Hegelm属的第一例。以吸湿方式生长(对浮萍来说是一种极其罕见的情况)，并且在哥斯达黎加首次记录了W. oblonga。

This also constitutes the first case of the genus Wolffiella Hegelm. growing in a hygropetric manner (an extremely rare condition for duckweeds) and the first record of W. oblonga in Costa Rica.","PeriodicalId":55556,"journal":{"name":"Adansonia","volume":"1 1","pages":"193-200"},"PeriodicalIF":0.8,"publicationDate":"2019-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74373381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The names Arctotis staticifolia Poir. and Arctotis tenuifolia Poir. were validly published by Jean Louis Marie Poiret based on material collected from “Cap de Bonne-Esperance” and stated to be lodged in the Herbier Desfontaines. No original material for Arctotis staticifolia has been traced. The protologue is inconsistent with any known Arctotis L. species and previous treatment of A. staticifolia as a synonym of Gazania linearis (Thunb.) Druce var. linearis is not supported. The protologue for Arctotis staticifolia is most consistent with a narrow-leaved taxon of Dimorphotheca Vaill. ex Moench and specifically D. nudicaulis (L.) DC. var. graminifolia (L.) Harv. A neotype for Arctotis staticifolia is designated consistent with our interpretation and the name is formally placed in the synonymy of Dimorphotheca nudicaulis var. graminifolia. Arctotis tenuifolia Poir. has previously been treated as a synonym of Dimorphotheca nudicaulis var. graminifolia. Original material was located and the name Arctotis tenuifolia Poir. is here lectotypified and is placed in the synonymy of Ursinia tenuifolia (L.) Poir. subsp. tenuifolia. Arctotis tenuifolia Poir. is a later heterotypic homonym of Arctotis tenuifolia L. and is therefore nomenclaturally illegitimate. A lectotype is designated for Sphenogyne tenuifolia (L.) DC. var. heterochroma Harv., a synonym of Ursinia tenuifolia subsp. tenuifolia.
这些植物的名字是树齿蕨(Arctotis staticifolia Poir)。和牛蒡。由让·路易·玛丽·波烈根据从《波恩-埃斯佩兰斯角》收集的材料有效地出版，并声称存放在赫比尔·德方丹。静止叶牛蒡的原始资料尚无记载。这一物种的起源与已知的任何一种都不一致，也不符合以往将其作为Gazania linearis (Thunb.)的同义词的处理。不支持生成var. linearis。静止叶大狐猴的起源与Dimorphotheca Vaill的一个窄叶分类群最为一致。ex Moench，特别是D. nudicaulis (L.)直流。谷草变种哈里。与我们的解释一致的是，一个新种被指定为staticifolia，并将其名称正式放置在Dimorphotheca nudicaulis var. graminifolia的同义词中。牛耳草。以前被认为是Dimorphotheca nudicaulis var. graminifolia的同义词。对原始材料进行了定位，并命名为牛蒡。是这里的lectotyptype和被放置在Ursinia tenuifolia (L.)的同义词。Poir。无性系种群。tenuifolia。牛耳草。是后来的异型同音词，因此在命名上是非法的。为细叶凤花(l.s henogyne tenuifolia)指定了一个选型。直流。异色的;，是小叶蕨亚属的同义植物。tenuifolia。
