Neckera humilis

Neckera humilis View in CoL ( Fig. 4 E–J)

Pellucid area around the bud is usually apparent, in some cases almost reaching the axil of the N+3 leaf ( Figs. 4E, I). Outermost proximal branch leaves are mainly arranged along the border of the pellucid area. They are often compound and their parts are well spaced one from another, so it is sometimes difficult to find out that two or more foliose structures are parts of the same leaf, and some assignings can be challenged ( Fig. 4H). One foliose structure marked ‘!’ in Fig. 4E stands behind the circle in which other proximal branch leaves are arranged, thus representing paraphyllium of Leskea - type as was defined by Spirina et al. (2020). Dormant branch buds in Neckera humilis look more variable in shape and size of proximal branch leaves compared to N. douglasii : some of them are very long and their phyllotaxis is sometimes questionable.
