一种新的Epipactis,来自南部喀尔巴山脉的Bucegi自然公园ROSCI0013,描述了罗马尼亚中部。在东南部发现了三个中等规模的Epipactisbucegensis种群(总共65-70个人),公园的亚高山地区。为了正确描述和区分新发现的分类单元与其他罗马尼亚Epipactis,直接从活体植物和花卉中测量了37个形态特征。此外,还包括详细的分类处理和描述,以及相应的彩色照片和线条图插图。Epipactisbucegensis是一种专性自交物种,部分类似于Epipactismuelleri,它在茎上叶子的基础分布上有所不同(与中位数分布);近乎直立的叶片姿势(与水平传播,向下拱形);披针形渐尖,黄绿色叶子(与椭圆形细长,鲜绿色的叶子);缺乏中胚层的二部唇瓣(vs.三方唇瓣);深红色,宽,卵形细长,扁平性低性障碍(与深棕色到黑色带圆形的下性交);三角形,白色表皮,顶点急剧变细(与心形,带钝角的黄绿色表皮,圆形顶点);和两个分开的,紫色,金字塔形愈伤组织(与两个紧密放置,衰减,轻度皱纹,黄绿色愈伤组织)。Epipactisbucegensis很容易与所有其他欧洲Epipactis类群区分开来,缺乏中胚层的宽唇瓣。此外,有关其分布的信息(地图),栖息地,生态学,提供物候和自然保护联盟保护评估。
A new species of Epipactis from Bucegi Natural Park ROSCI0013, Southern Carpathians, Central Romania is described. Three medium-sized populations of Epipactis bucegensis (65-70 individuals in total) were discovered in the south-eastern, subalpine area of the park. To properly describe and distinguish the newly found taxon from other Romanian Epipactis, 37 morphological characters were measured directly from living plants and flowers. Moreover, a detailed taxonomic treatment and description with corresponding colour photos and line drawings illustrations of the holotype are also included. Epipactis bucegensis is an obligate autogamous species that partially resembles Epipactis muelleri, from which it differs in the basal distribution of leaves on the stem (vs. median distribution); near-erect leaf posture (vs. horizontally spread, arched downwards); lanceolate-acuminate, yellowish-green leaves (vs. oval-elongate, vivid-green leaves); bipartite labellum lacking the mesochile (vs. tripartite labellum); crimson-red, wide, ovoid-elongated, flattened hypochile (vs. dark-brown to black roundish hypochile); triangular, white epichile with a sharply tapering apex (vs. heart-shaped, greenish-yellow epichile with obtuse, roundish apex); and two wide-apart, purple, pyramidal calli (vs. two closely placed, attenuated, mildly wrinkled, greenish-yellow calli). Epipactis bucegensis is easily distinguished from all other European Epipactis taxa by the bipartite, wide labellum that lacks the mesochile. In addition, information regarding its distribution (maps), habitat, ecology, phenology and IUCN conservation assessments are provided.
