摘要马蓝属(Strobilanthes Blume s. l.)是爵床科第二大属,全世界约400种,分布于亚洲的热带和亚热带地区。我国有116种,是中国爵床科种数最多的属,主要分布在华南和西南地区。马蓝属自建立以来,就有广义和狭义之争,在属的范围、属下系统上存在争议。本研究在野外考察和查阅国内外40多个标本馆的基础上对国产广义马蓝属进行了分类修订。 花粉形态在爵床科植物分类上具有非常重要的意义,自Lindau根据花粉形态特征建立了爵床科第一个分类系统以来,就受到广泛关注。Bremekamp根据花粉形态及种子特征将马蓝属细分为54个属,他的分类处理备受争议。本研究观察了国产马蓝属90种的花粉形态,根据花粉形状、表面纹饰、萌发孔及沟的特征,将国产马蓝属植物的花粉分成球形和长球形两大类。这两种类型的花粉分别又可进一步分为6个类型和8个类型。花粉形态特征不支持Bremekamp对马蓝属进行细分为54个属的处理,应将马蓝属处理为广义的概念。 确认我国有马蓝属植物115种1变种,另有引种1种广泛在热带地区广泛栽培,澄清了一些种类的分类学问题,给出了各种的分种检索表,对每种的形态特征、分布进行了描述,并引证了查阅过的凭证标本。根据花序、苞片、花萼、雄蕊及胚珠数目等将将国产马蓝属分为30组。澄清了安龙花属Dyschoriste Nees在中国的分布记录。原记载产中国的安龙花属Dyschoriste Nees并不产中国,记载的安龙花D. sinica H. S. Lo实际上是马蓝属的种类。描述了16个新种,发现中国新记录种11个,给出了15个新组合,纠正前人的错误鉴定8个,归并了28个名称为异名,5种列为存疑种。
其他摘要The genus Strobilanthes Blume s. l. is the second largest genus in the family Acanthaceae and consists of about 400 species distributed in Tropical and Subtropical regions of Asia. It is the largest genus in Chinese Acanthaceae and consists of 116 species and one variety distributed in S and SW China. It was disagree Pollen morphology plays the important roles in taxonomy and classification of the family Acanthaceae. Lindau established a system of the family based on the pollen morphology. Bremekamp splited the genus Strobilanthes into 54 genera based upon the characters of Pollen grains and the seeds. Bremekamp’s system was critical by many taxonomists. In the present paper, the pollen morphology of 90 species from China in Strobilanthes were investigated. The pollen morphology of Chinese Strobilanthes can be divided into two class of globose and ellipsoid that are subdivided into six types and eight types respectively. The results showed that Bremekamp’s system is not supported and suggested that the broadest concept of Strobilanthes should be recognized. Based on the field investigation and examination the specimens in more than 40 herbaria, Chinese Strobilanthes Blume s. l. is revised. There are 116 species including one cultivated species and one variety are recognized from China. According to the characters of inflorescence, bracts, calyx, stamens and ovule number, the Chinese species are placed into 30 sections. Dyschoriste Nees was reported from China by Lo with describing a new species D. sinica H. S. Lo. After axamination the type material, it reveals that D. sinica H. S. Lo is a member of the genus Strobilanthes Blume and the genus Dyschoriste Nees should be deleted from Flora of China. Sixteen new species are described. Eleven species are newly reported from China. Fifteen new combinations are proposed. Eight misidentified species are corrected. Three specieswere wrongly reported from China.. Twennty-eight names are reduced to the synonymy and the status five names are uncertain.
