Abstract:
Over the course of revising the genus Rinorea (Violaceae) from Colombia, field observations and herbarium studies revealed seven new species. Several of the new species described here belong to species complexes that required examination of herbarium material from across the Neotropics. Each of the new species described here have oppositely arranged leaves and belong to Rinoreasect.Pubiflorae, a section restricted to the Neotropics. Two new species are segregated from the R.ovalifolia species complex: Rinoreachiribiquetensis from Chiribiquete National Park in the Colombian Amazon and Rinoreastevensii from the Orinoco River near the border of Colombia and Venezuela. Two new species are segregated from the Rinoreahirsuta species complex: Rinoreagaleanoae-bernalii and Rinoreacogolloi, both from the eastern slopes of the Andean Central Cordillera along the mid-Magdalena River Valley in Colombia. From the widely distributed R.pubiflora species complex, we segregated one new species, Rinoreacallejasii, from southeast Panama and the Chocó in Colombia. In addition to these five new taxa segregated from widely distributed species complexes, we discovered two previously unknown species with affinities to other Neotropical Rinorea. Rinoreaaymardii is described from the Alto Orinoco-Casiquiare Biosphere Reserve in Venezuela and most closely resembles R.melanodonta from Colombia. Rinoreabetancurii is segregated from R.macrocarpa and occurs in the Amazonian Regions of Colombia, Brazil, Peru and Venezuela. In this study, we provide descriptions, illustrations and distribution maps of the new species and make preliminary assessments of the risk of extinction using the IUCN Red List Categories and Criteria. We also furnish an identification key to the species of Rinoreasect.Pubiflorae in Colombia.
摘要:
在修改哥伦比亚的Rinorea属(紫罗兰科)的过程中,野外观察和植物标本室研究揭示了七个新物种。此处描述的几个新物种属于需要检查来自新热带地区的植物标本室材料的物种复合物。这里描述的每个新物种都有相反排列的叶子,属于Rinoreect。Pubiflorae,限制在新热带地区的部分。两个新物种与卵形单胞菌物种群隔离:来自哥伦比亚亚马逊Chiribiquete国家公园的Rinoreachiriibiquetensis和来自哥伦比亚和委内瑞拉边界附近的奥里诺科河的Rinoreastevensii。从Rinoreahirsuta物种复合体中分离出两个新物种:Rinoreagaleanoae-bernalii和Rinoreacogolloi,两者都来自哥伦比亚马格达莱纳河谷中部的安第斯中央山脉的东坡。从广泛分布的R.pubiflora物种复合体中,我们隔离了一个新物种,Rinoreacallejasii,来自巴拿马东南部和哥伦比亚的乔科河。除了这五个新的分类群与广泛分布的物种复合物分开,我们发现了两个以前未知的物种,它们与其他新热带Rinorea具有亲和力。Rinoreaaymardii来自委内瑞拉的AltoOrinoco-Casiquare生物圈保护区,最类似于哥伦比亚的R.melanodonta。Rinoreabetancurii与R.macrocarpa隔离,发生在哥伦比亚的亚马逊地区,巴西,秘鲁和委内瑞拉。在这项研究中,我们提供描述,新物种的插图和分布图,并使用IUCN红色名录类别和标准对灭绝风险进行初步评估。我们还提供了Rinoreect物种的识别钥匙。哥伦比亚的Pubiflorae。
