A recent molecular phylogenetic analysis of the Caesalpinia group demonstrated that it comprises 26 genera, but the recognition of a putative 27 genus, , remained in doubt. This study presents a phylogenetic analysis of ITS and five plastid loci revealing a robustly supported monophyletic group representing the Ticanto clade, sister to the morphologically distinct genus . Based upon this evidence, along with a morphological evaluation, the genus is here reinstated. Descriptions are provided for all nine species of , together with a key to the species, maps, and colour photographs. Nine new combinations are made: (Hand.-Mazz.) R. Clark & Gagnon, (L.) R. Clark & Gagnon, (S. J. Li, Z. Y. Chen & D. X. Zhang) R. Clark & Gagnon, (Metcalf) R. Clark & Gagnon, R. Clark & Gagnon, (Hemsl.) R. Clark & Gagnon, (Craib) R. Clark & Gagnon, (Champion ex Benth.) R. Clark & Gagnon and (S. J. Li, D. X. Zhang & Z.Y. Chen) R. Clark & Gagnon. The final major question in the delimitation of segregate genera from within and the Caesalpinia group is thus resolved.
最近对云实属的分子系统发育分析表明，它包含26个属，但一个假定的第27个属的认定仍存疑问。本研究对ITS和五个质体基因座进行了系统发育分析，揭示了一个得到有力支持的单系类群，代表了Ticanto分支，它是形态上不同的属的姐妹群。基于这一证据，结合形态学评估，此处恢复了该属。文中提供了该属所有九个物种的描述，以及物种检索表、分布图和彩色照片。提出了九个新组合：(Hand.-Mazz.) R. Clark & Gagnon、(L.) R. Clark & Gagnon、(S. J. Li, Z. Y. Chen & D. X. Zhang) R. Clark & Gagnon、(Metcalf) R. Clark & Gagnon、R. Clark & Gagnon、(Hemsl.) R. Clark & Gagnon、(Craib) R. Clark & Gagnon、(Champion ex Benth.) R. Clark & Gagnon和(S. J. Li, D. X. Zhang & Z.Y. Chen) R. Clark & Gagnon。因此，从云实属和云实亚科中划分出不同属的最后一个主要问题得到了解决。
