Abstract

ABSTRACT Riella affinis Howe & Underwood is a rare species that is thus far known from eight populations worldwide. Only half of these were recorded in the last 50 years and none were recollected since first reported. Study of a Spanish population of R. cossoniana Trab., recorded in 2002 from Las Lomas, Malaga province, revealed that it belongs to R. affinis. The correct identity of the populations, which had not been available for study, was already suggested by reproductive and ecological characteristics of the plants mentioned in the original publication. The three main lagoons from the Las Lomas endorheic system, where the plants had been recorded, were sampled and living plants of R. affinis were found in Viso lagoon whereas culture of sediments yielded plants of this species from Viso and Caja lagoons. Riella affinis is new to continental Europe and the new Spanish populations are described and illustrated in detail. Riella cossoniana is excluded from Malaga province. Riella affinis is classified as critically endangered (CR) globally and for Spain; the new Iberian populations should be targeted for conservation. An identification key to the currently recognised European species of Riella Mont. is included.

文章标题欧洲大陆新发现的亲缘梨科植物Howe & Underwood的完整描述与保护评价

Howe & Underwood Riella affinis Howe & Underwood是一种稀有物种，目前在全球共有8个种群。其中只有一半是在过去的50年里被记录下来的，而且自第一次报告以来没有一个被回忆起来。一个西班牙大鼠种群的研究。2002年在马拉加省拉斯洛马斯记录的一种名为R. affinis的昆虫。原始出版物中提到的植物的生殖和生态特征已经表明，这些种群的正确身份尚未可供研究。在记录了该植物的Las Lomas内源性系统的三个主要泻湖中进行了取样，在Viso泻湖中发现了活的affinis植物，而沉积物培养则在Viso和Caja泻湖中发现了该物种的植物。Riella affinis是欧洲大陆的新物种，新的西班牙种群被详细描述和说明。Riella cossoniana被排除在马拉加省之外。在全球和西班牙被列为极度濒危(CR);新的伊比利亚种群应该成为保护的目标。目前已确认的Riella Mont欧洲物种的鉴定关键。包括在内。
