Lectotypification, epitypification and history of the name Plagiothecium neglectum Mönk. (Plagiotheciaceae)

description In the protologue of Plagiothecium neglectum, Mönkemeyer (1927) does not indicate any herbarium specimen as a type. The author only gave a short description and attached a figure illustrating selected features of this taxon. The original materials from the Mönkemeyer collection were deposited in the HBG herbarium; however, it is not currently possible to determine their location. Furthermore, one specimen of P. neglectum, currently known from the original Mönkemeyer collections, was found in the Herbarium B (B 30 0105646). The features given in the diagnosis of this taxon are consistent with those of the lectotype of Stereodon nemoralis Mitt.; only the leaf apex from Figure 207c (Mönkemeyer 1927) is different and thus suggests mixed material. According to Art. 9.1 of the Shenzhen Code, Figure 207c represents a holotype of P. neglectum. However, due to differences in the leaf apex and according to Art. 9.3 of the Shenzhen Code, the part representing the apex should be excluded from the holotype, and the remainder of Figure 207c is consequently designated as a lectotype of the name P. neglectum. However, because the lectotype does not include a complete set of significant distinguishing features, an epitype (B 30 0105646) was designated.
