关于中国薹草属高秆薹草组(莎草科)的分类问题

《中国植物志》中记载的薹草属高秆薹草组包括区别显著的两类植物,一类具有间断的穗状花序和叶状苞片,另一类穗状花序紧密、苞片鳞片状或刚毛状,宜分为两个不同的组：高秆薹草组和卵形薹草组。文中将高秆薹草组和卵形薹草组与近缘的薮薹草组进行了形态学比较,并提供了中国高秆薹草组和卵形薹草组的分类纲要。     

浙江薹草属（莎草科）一新种——近头状薹草

报道了浙江薹草属一新种,即近头状薹草Carex subcapitata X.F.Jin,C.Z.Zheng&B.Y.Ding。新种以秆侧生,叶片狭,小穗1-2个生于各节及小穗雄雌顺序,而与大舌薹草C.grandiligulata K kenth.相近,区别在于苞鞘无毛,小穗宽卵形,近头状,长5-7mm,具4-7 朵雌花,雌花鳞片近卵形,果囊的喙长1.5-2mm。     

福建薹草(莎草科)的考证

在整理和鉴定浙闽薹草属Carex植物的过程中,发现福建薹草Cares fokienensis Dunn较早发表但并未被注意。通过文献查阅、模式标本研究和野外观察,认为闽清薹草C.minqingensis Z．P.Wang、九仙山薹草C jiuxiangshanensis L.K．Dai＆Y.Z．Huang、苍绿薹草C.pallideviridis K．L．Chv（裸名）在果囊和雌花鳞片等鉴别性特征上与福建薹草并没有区别,应该处理为福建薹草的异名。     

中国莎草科一新记录种——菊芳薹草

报道了中国莎草科(Cyperaceae)薹草属一新记录种——菊芳薹草(Carex trongii K.K.Nguyen)。该种分布于我国广西与越南交界地区的石灰岩地区。菊芳薹草与宽叶薹草组(Carex sect.Siderostictae Ohwi)的种类在形态上近似,但以秆中生和果囊密被糙毛而易于区别。提供了菊芳薹草的形态描述和线条图。     

中国薹草属二柱薹草亚属（莎草科）增补

报道了发现于新疆布尔津的一个中国新记录种——卵形薹草Carex leporina L.,提供了其形态描述和线描图。该种因具有雌雄顺序的小穗和鳞片状的苞片而与卵果薹草C. maackii Maxim.近缘,但花序较短、小穗较少而与后者不同。这两种植物隶属于薹草属二柱薹草亚属卵形薹草组subgen. Vignea sect. Ovales。

Carex damiaoshanensis X. F. Jin & C. Z. Zheng,a new species of Cyperaceae from Guangxi,China

Carex damiaoshanensis X. F. Jin & C. Z. Zheng, a new species of Cyperaceae from Guangxi, China, is described and illustrated. This new species resembles C. scaposa C. B. Clarke in its arundinaceous leaves and spikes arranged in a compound panicle, but differs from the latter in having glabrous culms, cauline leaves, and rachises of secondary inflorescences, panicle with fewer secondary inflorescences, and spikes with sparse pistillate flowers. Micromorphology of culms, cauline leaves, peduncles of secondary inflorescences, and achenes under SEM supports the recognition of this new species as well.

Centotheca ganeshaiahiana M. V. Ramana, Alok Chorghe, Prasanna & Sanjappa, a new species from Saddle Peak National Park, north Andaman, Andaman and Nicobar Islands, India is described and illustrated. It is closely allied to C. uniflora Swallen, a Vietnamese species, but differs mainly in shorter culms, leaf blades and inflorescences, longer pedicels, spikelets with 2 fertile florets and lemmas with bulbous based hairs.
