摘要:凤仙花属植物是所凤属植重要的分类群之一,
中国科学院昆明植物研究所税玉民研究员带领其研究组针对此问题对凤仙花属植物花结构信息的仙花野外采集方法进行了研究和探索。探索并制定出一套关于凤仙花属植物花结构特征信息野外采集的物传新方法,随着现代信息采集技术的统分进步发展,获得了这三个种的类学野外活植物的第一手资料。使得凤仙花属植物的研究蜡叶标本制作工作十分困难,
相关研究结果已发表在2011年第2期的获新Systematic Botany期刊上。然而,进展在凤仙花属的昆明传统分类学研究中,全世界约900种,植物在凤仙花属的所凤属植传统分类学研究中,现代传统分类学研究对植物材料和植物特征结构信息描述的仙花准确性要求越来越高,可以得到野外活植物结构特征的物传准确而详实的第一手资料。通过应用这样的新方法,由于其具有极高的观赏性而备受重视。花的结构受到破坏,然而,在压制成为蜡叶标本后,对花结构的描述和绘图就带有了很大的猜测性。使得凤仙花属植物的蜡叶标本制作工作十分困难,各个组成部分相互粘粘而难以分离,通过以新发表的三个种Impatiens aconitoides, I. purpureifolia以及I. rugata为例,由于其具有极高的观赏性而备受重视。并拍摄了高清彩色照片,由于其花朵结构复杂而质地极其脆弱,在压制成为蜡叶标本后,在传统的基于模式标本的描述中,由于其花朵结构复杂而质地极其脆弱,在野外直接采集活植物特征结构的第一手资料就成了必然要求。对蜡叶标本花的解剖就难以进行。详尽和有效地采集了以上三个种的花结构信息,

Three New Species of Impatiens L. from China and Vietnam: Preparation of Flowers and Morphology of Pollen and Seeds
Abstract
The genus Impatiens (Balsaminaceae) is one of the most difficult genera for making effective herbarium specimens because of its tender and complicated flowers. The preparation of flowers is always one of the most important steps in the collections of Impatiens. The present paper demonstrates a method to prepare flowering specimens of Impatiens in the field. Examples include three new species collected from the Sino-Vietnamese border, viz.Impatiens aconitoides,I. purpureifolia , andI. rugata . The related species I. laojunshanensis, I. apalophylla, and I. clavigera are also sampled using the same preparation method. As to the three new species, their pollen grains and seeds were observed by scanning electron microscopy. Impatiens aconitoides has 4-colpate pollen grains and ovoid seeds with protrusivetype of seed coat, whereasI. purpureifolia andI. rugata have 3-colpate grains and ellipsoidal seeds with reticulate-typed seed coat. Such an integrated approach to include detailed floral characters as well as pollen and seed characters is proposed when new taxa of Impatiens are described.
