Abstract The species in Ledebouria sect. Resnova are revised, with an identification key, full nomenclature, descriptions, ecological notes, and illustrations. Sect. Resnova is defined by its deeply campanulate flowers with tepals shortly connate basally and erect throughout or spreading distally; biseriate stamens with white, filiform filaments; sessile or subsessile ovary; and diagnostic seeds, obliquely obovoid with an inflated and invaginated raphe, and a finely puberulous-echinulate testa. Five species are recognised, divided between the monotypic ser. Lachenalioides, diagnosed by larger flowers with multi-nerved tepals, and ser. Resnova, with smaller flowers and uni-nerved tepals. Species in ser. Resnova are distinguished primarily by the presence or absence of hairs on one or both surfaces of the leaves, and by the presence or absence of a pseudopetiole. The new species Ledebouria hardyi J.C.Manning is described for a collection of plants from near Burgersfort in Limpopo with mostly solitary, markedly pseudopetiolate foliage. The species in sect. Resnova are geographically and ecologically separated by altitude and climate. A revised subtribal classification is provided for Massonieae, based on available phylogenetic hypotheses. Three subtribes are recognised: the monotypic Merwillineae is described for the genus Merwilla and is diagnosed by its white ovary and beige seeds; the genus Schizocarphus is transferred to join Ledebouria in Ledebouriinae, which is weakly diagnosed by the development of multiple inflorescences in some species and a flexuous scape; and Lachenaliinae is included within Massoniinae, which comprises all remaining genera in the tribe and is diagnosed by its few to many subglobose seeds per locule and often tunicated bulbs. This classification replaces existing hypotheses, which are inconsistent with available morphological and phylogenetic data.

Ledebouria 教派的系统学。Resnova（风信子科：Scilloideae：Massonieae），具有新的Massonieae亚部落分类

摘要 Ledebouria sect 中的物种。Resnova 进行了修订，带有识别码、完整的命名法、描述、生态注释和插图。教派。Resnova 的定义是它的深钟状花，花被片基部短合生并直立或向远端蔓延；双列雄蕊具白色丝状花丝；无柄或近无柄卵巢；和诊断种子，斜倒卵球形，具有膨胀和内陷的中缝，和一个细密的有微柔毛的种皮。五个物种被识别，分为单型系列。Lachenalioides，由具有多神经花被片的较大花诊断，和ser。Resnova，具有较小的花朵和单神经花被片。系列中的物种。Resnova的主要区别在于叶子的一个或两个表面上是否存在毛发，以及假叶柄的存在与否。新物种 Ledebouria hardyi JCManning 被描述为来自林波波省 Burgersfort 附近的一组植物，其主要是单生的、明显的假叶柄。科中的物种。Resnova 在地理和生态上因海拔和气候而分离。根据可用的系统发育假设，为马尾松亚科提供了修订的亚部落分类。识别出三个亚部落：单型 Merwillineae 被描述为 Merwilla 属，并通过其白色子房和米色种子进行诊断；Schizocarphus 属被转移到 Ledebouriinae 中加入 Ledebouria，通过在某些物种中发育多个花序和弯曲的花序而弱诊断；和 Lachenaliinae 包含在 Massoniinae 中，它包括部落中所有剩余的属，并通过每个室中很少到许多近球形的种子和经常被囊肿的球茎来诊断。这种分类取代了现有的假设，这些假设与可用的形态学和系统发育数据不一致。
