摘要：来自坦桑尼亚和安哥拉湿润 miombo 林地的新种 Argyrella richardsiae Veranso-Libalah 和 G.Kadereit, sp.。十一月（野牡丹科，野牡丹科），进行了描述和说明。虽然广泛分布的白银银藻也出现在坦桑尼亚和安哥拉东北部，但理查银银藻在形态上与仅产于喀麦隆西北部的斑布银银藻最相似，但不同之处在于整个植物上的腺毛毛被（与其他银银藻物种中星状和腺毛的混合物）、叶片边缘有锯齿。 （相对于 A. bambutorum 的整个边缘）和侧神经在中途变得微弱并且永远不会到达叶尖（相对于 A. bambutorum 的明显侧神经从基部到顶端）。根据 IUCN 红色名录类别和标准，建议将理查氏菌列为濒危 (EN) 初步保护状态。还包括所有阿吉里拉物种的分类学索引和分布图。
Abstract A new species from the wet miombo woodlands of Tanzania and Angola, Argyrella richardsiae Veranso-Libalah & G.Kadereit, sp. nov. (Melastomataceae, Melastomateae), is described and illustrated. Although the widespread Argyrella canescens also occurs in Tanzania and northeastern Angola, A. richardsiae is morphologically most similar to Argyrella bambutorum known only from the Northwest of Cameroon, but differs by its indumentum of glandular trichomes on the entire plant (versus a mixture of stellate and glandular trichomes in other species of Argyrella), leaf-blades with serrulate margins (versus entire margins in A. bambutorum) and lateral nerves that become faint mid-way and never reach the leaf apex (versus conspicuous lateral nerves percurrent from the base to the apex in A. bambutorum). A preliminary conservation status of Endangered (EN) is proposed for A. richardsiae following the IUCN Red List Categories and Criteria. A taxonomic key and distribution map of all Argyrella species is also included.
