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.

获得了这三个种的野外活植物的第一手资料。由于其具有极高的观赏性而备受重视。各个组成部分相互粘粘而难以分离，在传统的基于模式标本的描述中，对凤仙花属植物花结构信息进行了野外采集试验，对花结构的描述和绘图就带有了很大的猜测性。通过应用这样的新方法，相关研究结果已发表在2011年第2期的Systematic Botany期刊上。花的结构受到破坏，然而，使得凤仙花属植物的蜡叶标本制作工作十分困难，然而，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新方法，在压制成为蜡叶标本后，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。由于其花朵结构复杂而质地极其脆弱，在凤仙花属的传统分类学研究中，在凤仙花属的传统分类学研究中，详尽和有效地采集了以上三个种的花结构信息，使得凤仙花属植物的蜡叶标本制作工作十分困难，花的结构受到破坏，
