strong>When morphology and molecules tell us different stories, part 2: Pinnatella homaliadelphoides (Neckeraceae), a new moss species from China and India</strong
Article
  • Dec 2010
Pinnatella homaliadelphoides Enroth, S. Olsson, S. He, Shevock & D. Quandt (Neckeraceae, Bryophyta) is illustrated and described from China and India. Morphologically, it differs strongly from all known species of Pinnatella, but shares many features characteristic of Homaliadelphus Dixon & P. de la Varde (Miyabeaceae). The generic placement is therefore evaluated by molecular methods. Sequence data from the plastid rps4-trnT-trnL-trnF cluster as well as the rpl16 group II intron and the nuclear ITS1 & 2 place Pinnatella homaliadelphoides sister to P. foreauana Thér. & P. de la Varde, both sharing the same general geographical distribution range.

Phylogenetic relationships in the ‘Pinnatella’ clade of the moss family Neckeraceae (Bryophyta)
Article
  • Apr 2010
The family Neckeraceae is composed of three distinct clades, of which two, i.e. the Neckera and Thamnobryum clades, are well defined. The third clade, consisting of species belonging to Caduciella, Curvicladium, Handeliobryum, Himantocladium, Homaliodendron, Hydrocryphaea, Neckera, Neckeropsis, Pinnatella, Shevockia and Taiwanobryum, is the focus of this study. Based on sequence data from the trnS-rps4-trnT-trnL-trnF plastid cluster and the rpl16 intron as well as from nuclear ITS1&2, the phylogenetic relationships of these genera are reconstructed. The nearest relatives of this clade are resolved shedding more light on the evolution of the family. The generic composition of the clade and its individual genera are discussed; polyphyly requires redefinition of Pinnatella, Neckeropsis and Homaliodendron. The positions of Touwia and Homalia within the family are addressed in an additional analysis based on more extensive sequence data, and the corresponding new combinations are made. Several further taxonomic changes are proposed, including Circulifolium gen. nov., comprising the former Homaliodendron exiguum and H. microdendron.
