摘要

摘要:对龙舌兰(Agave convallis)和龙舌兰(A. dissimulans)的分类进行了讨论和澄清。研究结果表明，与小圆叶蝉名称相关的两个释4号标本不是重复的(它们有不同的采集日期)。1905年2月5日的第4批标本(条形码MO-1128755;MO标本编号3346866)是A. convallis的原型，而另一个发布4号标本的日期为1905年2月12日(条形码MO-1256267;MO标本号3346867)为模式型。我们确认了A. dissimulans这个名字的lectotyptype，其中一个标本的年份为1905年2月11日(条形码MO-1128757;MO标本编号3346870)。另一个版本81的标本，也是1905年2月11日(条形码MO-1128758;MO标本号3346869)，为等异型。第82号版本的分类状态，其日期也为1905年2月11日[条形码MO-1256273;MO标本号3346871]，为模式型。这里提到的所有释出标本都保存在密苏里植物园的植物标本室。为了完整起见，我们还参考了龙舌兰(Agave kerchovei Lem)这个名字的类型化，并澄清了它的词源。本种是小圆蝽和假蝽的近亲。

Notes on the Typification and Nomenclature of Agave dissimulans Trelease, Agave convallis Trelease, and Agave kerchovei Lem. (Asparagaceae: Agavoideae / Agavaceae)

Abstract: The typification of the names Agave convallis Trelease and A. dissimulans Trelease is discussed and clarified. We show that the two Trelease 4 specimens associated with the name A. convallis are not duplicates (they have different collecting dates). The Trelease 4 specimen dated 5 February 1905 (barcode MO-1128755; MO specimen number 3346866) is the lectotype of the name A. convallis, while the other Trelease 4 specimen dated 12 February 1905 (barcode MO-1256267; MO specimen number 3346867) is a syntype. We confirm the lectotypification of the name A. dissimulans, with one of the two Trelease 81 specimens dated 11 February 1905 (barcode MO-1128757; MO specimen number 3346870). The other Trelease 81 specimen, which is also dated 11 February 1905 (barcode MO-1128758; MO specimen number 3346869), is an isolectotype. The typification status of Trelease 82, which is also dated 11 February 1905 [barcode MO-1256273; MO specimen number 3346871], is that of syntype. All the Trelease specimens mentioned here are held in the Herbarium of the Missouri Botanical Garden (MO). For the sake of completeness we also refer to the typification, and clarify the etymology, of the name Agave kerchovei Lem. This species is a close relative of A. convallis and A. dissimulans.
