苦苣苔科吊石苣苔属一新异名

2017年，印度学者Joe等基于采自中国藏东南地区的植物标本，发表了合萼吊石苣苔的一新变种Lysionotus gamosepalus W. T. Wang var.biflorus A. Joe, Hareesh&M. Sabu,并且认为该新变种与原变种的主要区分特征包括叶缘稍具锯齿、每个腋生花序仅有2朵花、花冠被毛、具2枚卷曲的退化雄蕊。然而，近年来，笔者基于查阅大量标本和野外考察工作，认为所谓变种的形态特征是在合萼吊石苣苔(Lysionotus gamosepalus W. T. Wang)的变异范围之内，加之分布区完全重叠，生长环境类似，物候期一致，不宜作为变种等级处理。故在此将该变种处理为合萼吊石苣苔的异名。     

Hemiboea purpurea sp. nov. (Gesneriaceae) from a limestone area in Guangxi,China

Hemiboea purpurea Yan Liu & W. B. Xu, a new species of Gesneriaceae from Guangxi, China, is described and illustrated. The new species is similar to H. follicularis C. B.

Two new species and a new series of Elatostema (Urticaceae) from China

The new series Elatostema section Elatostema series Albopilosoides Q.Lin & L.D.Duan (Urticaceae) is described, and two new species of Elatostema, namely Elatostema albopilosoides Q.Lin & L.D.Duan and Elatostema purpureum Q.Lin & L.D.Duan. from south Guizhou province, south‐west China are described and illustrated. Both species were found growing only at the base of a large limestone chamber at an altitude of c. 800 m. Elatostema albopilosoides is morphologically similar to E. albopilosum W.T.Wang, but differs by having female inflorescences with peduncles 10–60 mm long (0–1.5 mm long in E. albopilosum) and receptacles 7–27 mm long, 7–24 mm wide (E. albopilosum: 1–4 mm long and 1–3 mm wide). Elatostema purpureum is also morphologically similar to E. albopilosum, but has stipules 5–6 mm long, 0.8–1.5 mm wide (4–7 mm long, 1.5–2.8 mm wide in E. albopilosum) and leaf blades obliquely elliptical to obliquely oblong‐obovate, 3.5–7.5 mm long and 1.5–2.5 mm wide (obliquely narrowly oblanceolate‐oblong, 12–17 cm long, 3–5 cm wide in E. purpureum:). © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 674–680.     

Tinocladia sanrikuensis sp. nov. (Ectocarpales s.l., Phaeophyceae) from Japan

The new species Tinocladia sanrikuensis sp. nov. H.Kawai, K.Takeuchi & T.Hanyuda (Ectocarpales s.l., Phaeophyceae) is described from the Pacific coast of the Tohoku region, northern Japan based on morphology and DNA sequences. The species is a spring–summer annual growing on lower intertidal to upper subtidal rocks and cobbles on relatively protected sites. T. sanrikuensis has a slimy, cylindrical, multiaxial erect thallus, slightly hollow when fully developed, branching once to twice, and resembles T. crassa in gross morphology. The erect thalli are composed of a dense medullary layer, long subcortical filaments, and assimilatory filaments of 11–35 cells, up to 425 μm long and curved in the upper portion. Unilocular zoidangia are formed on the basal part of assimilatory filaments. The species is genetically most closely related to T. crassa and has the same basic thallus structures but differs in having thinner and longer assimilatory filaments. DNA sequences of the mitochondrial cox1 and cox3, chloroplast atpB, psaA, psbA and rbcL genes support the distinctness of this species.     

云南翠雀花属二新种

该文描述了自云南西北部发现的毛茛科翠雀花属二新种:短葶翠雀花(Delphinium breviscaposum W.T.Wang)和丝苞翠雀花(D.filibracteolum W.T.Wang)。短葶翠雀花与察隅翠雀花(D.chayuense W.T.Wang)在亲缘关系上相近,前者与后者的区别在于短葶翠雀花植株具3条簇生短花葶,总状花序的轴和花梗无毛,小苞片较长,萼片较小,退化雄蕊的瓣片不分裂;丝苞翠雀花与拟长距翠雀花(D.dolichocentroides W.T.Wang)近缘,前者与后者的区别在于丝苞翠雀花的花组成圆锥花序,花梗、萼片和萼距均较短,退化雄蕊的爪无附属物,心皮无毛。     

葡萄属一新名和一新种

描述了自甘肃南部发现的葡萄属一新种,文县蘡薁(Vitis wenxianensis W. T. Wang)。此新种与特产浙江的三出蘡薁[V. bryoniifolia Bunge var. ternata(W. T. Wang)C. L. Li]有很近的亲缘关系,二者可能是由蘡薁(V. bryoniifolia Bunge)衍生而出的一对姊妹群。基于上述认识,将三出蘡薁由变种提升至种的等级,但由于存在一个于1871年发表的种名(V. ternata Baker),因此,必须为三出蘡薁拟定一新名。     

Grateloupia Serra sp. nov. H. W. Wang & Y. Lou (Halymeniaceae,Rhodophyta): a new species previously confused with Grateloupia asiatica in China

A new Grateloupia species from Luxun park, Qingdao Province, North China, was discovered during recent investigations and named Grateloupia serra H. W. Wang &; Y. Lou sp. nov. Morphological observations showed that: (1) the thalli were purple to dark red, cartilaginous and mucilaginous in texture, 15–45?cm in height; (2) the surface of thalli was covered with numerous proliferous branchlets and proliferous branchlets that were dentate when on the main axes; (3) the thalli were 450–550?µm thick, a cortex consisted of 6–8 layers of oblong or rounded cells and a medulla covered by compact medullary filaments; (4) the carpogonial branch was 6-celled and the auxiliary-cell branch was 5-celled, they were typical Grateloupia-type; (5) the internal structure of mature tetrasporangia were cruciately divided, oblong or square in shape. The morphological differences were supported by molecular analyses based on ribulose-1, 5-bisphosphate carboxylase/oxygenase gene (rbcL) sequences. Sequences of four G. serra sp. nov. samples were embedded into the Grateloupia clade and showed no pairwise divergence.
