COMMENTS
In Africa, Bizot (1965, 1973) and Yu et al. (2011) treated five species as synonyms of G. tomentosa. G. thraustophylla, an old Cameroon species, was described by Müller (in Brotherus 1897), noted that “speciei praecedenti M. sarcotrichum Müll. Hal. (accepted name: Groutiella tomentosa) quoad foliorum structura omuino conveniens”. The differences between G. thraustophylla and G. sarcotrichum (accepted name: G. tomentosa) were “sed statura multo giaciliore; ramulis laxius dispositis, foliis crispulo-imbricatis, summo apice ramuli tantum indistincte spiraliter contortis, dorso rugulosis dignoscenda” (Müller in Brotherus 1897). The variation of the charateristics mentioned is all within the concept of G. tomentosa. Here we treat G. thraustophylla as a synonym of G. tomentosa.
Brotherus described the leaves of Groutiella subgoniorrhyncha as being “oblongo-lanceolata, sensim auguste acuminate, acumine saepe diffracto”, the characters of leaf shape, apex are all identical to the ones of G. tomentosa. We confirmed Brotherus’ description based on the type specimen; therefore, we treat it as a synonym of G. tomentosa.
The diagnostic characters for Groutiella tomentosa are the fragile, cuspidate to stoutly subulate leaves and the papillose basal leaf cells. The long, fragile subulae of the upper leaves are usually wider and fewer in the specimens from Africa than from other places (e.g. Magill 11432, Magill & Pócs 10960). G. reesei is the only other species with fragile leaf apex in the genus, the differences between them can be found in discussion of G. reesei. G. tuberculata B.H. Allen & I.H. Holz another species in the genus with papillose basal leaf cells, but the papilla of itis much more obvious than G. tomentosa, meanwhile it never has a fragile apex.
There are some differences between the upper and lower leaves in G. tomentosa. The upper leaves are narrowed to a long, fragile subula (to 1 mm long). While the lower leaves usually have acute, non-fragile tips, which are similar to the leaves of G. chimborazensis, but G. chimborazensis never has a long, fragile leaf apex.
