Abstract

: Fusion, sculptures and ornamentation of the corolla pieces of 17 species of Papilionoideae. The species of subfamily Papilionoideae present flowers with a complex architecture, with elaborated petals in which it has been documented the presence of auricles and callosities, appendixes or spurs that joint the pieces of the corolla and also microsculpturings on the wings. In this study, we analyze the morphology of the petals of 17 species of Papilionoideae (Leguminosae) native of Salta province, Argentina. The lower margins of the keel were fused in all of the species, through different types of fusion of epidermal cells. Only a few species presented fusion in the upper margin of the keel. All the species showed sculpturings in the petals, which would joint some of the pieces of the corolla. They also exhibit ornaments or microsculpturings in the basal region of the adaxial surface of the wings that may act as a grip for pollinators when they land on the flower. The petals of the Papilionoideae flowers presented characteristics that could restrict the type of pollinator able to activate the different mechanisms of pollination that allow them to access the rewards enclosed by the keel.

17种凤蝶科花冠碎片的融合、雕塑和装饰

: 17种凤蝶科花冠片的融合、雕刻和装饰。Papilionoideae亚科的物种呈现出具有复杂结构的花朵，精心制作的花瓣中有记录的耳廓和胼胝，连接花冠碎片的阑尾或刺，以及翅膀上的微雕刻。本研究对原产于阿根廷萨尔塔省的17种凤蝶科(Papilionoideae，豆科)的花瓣形态进行了分析。所有种类的龙骨下缘均通过不同类型的表皮细胞融合而融合。只有少数种在龙骨上缘出现融合。所有种类的花瓣上都有雕刻，这些雕刻会连接花冠的一些碎片。它们在翅膀正面的基部也有装饰或微雕刻，当传粉者降落在花上时，这些装饰或微雕刻可能是它们的抓地力。凤蝶科花的花瓣表现出的特征可能会限制传粉者的类型，这些传粉者能够激活不同的传粉机制，从而使它们能够获得龙骨所包含的奖励。

期刊介绍： Bol. Soc. Argent. Bot. publishes original scientific works from the whole spectrum of Plant Biology (structure, anatomy, development, physiology, cytology, genetics, evolution, ecology, paleobotany, palynology, ethnobotany, etc.) in the diverse vegetable organisms and related groups (mycology, ficology, lichenology, briology, etc.), both in basic and applied aspects. Taxonomic works (of systematics, phylogeny, monographs, revisions, lectotypifications, nomenclatural acts, descriptions of taxa), phytogeographic and phytosociological works (survey and classification of vegetation at different spatial scales and without restriction of methodological approaches) are considered for publication. Contributions that address complete phytogeographic units or sub-units and those that fill gaps in knowledge of vegetation in little-known territories are especially welcome. Extensions of geographical areas are published only when it comes to new citations for a country. Checklists and lists of annotated plants are not published. Articles submitted for publication must be original and must not have been submitted to another publisher or previously published (print or electronic format). Submissions of papers already published in another language will not be accepted (autoplagio for translation).
