Taxitheliellarevisited and a new form of leaf cell outgrowth in Sematophyllaceaesensu lato

“…Fabroniaceae: A familial placement in Fabroniaceae, as suggested by Dixon (1935), seems unlikely, as there are no pluripapillose leaf cells observed in any bona fide species of Fabroniaceae. Also according to Câmara & Magill (2009), Cox et al (2010, and Câmara & Buck (unpublished data, 2011), Fabroniaceae, as currently circumscribed, is polyphyletic, and the possible synapomorphy (for Fabronia and Ischyrodon), which is the presence of wavy-walled exothecial cells, is absent in Taxitheliella.…”

“…Since its inception, this poorly known genus has been placed in different families, such as Sematophyllaceae (Dixon, 1935), Hypnaceae (Tan et al, 2000;Interactive Malesian Moss Database, 2009), Pylaisiadelphaceae (Goffinet & Buck, 2004;Goffinet et al, 2009), and is listed as Fabroniaceae in TROPICOS (www.tropicos.org). Dixon (1935) had considered its only species (T. richardsii) closely related to the genus Taxithelium, and therefore a member of the family Sematophyllaceae sensu lato.…”

“…Dixon (1935) had considered its only species (T. richardsii) closely related to the genus Taxithelium, and therefore a member of the family Sematophyllaceae sensu lato. His opinion was basically influenced by the presence of multiple leaf cell outgrowths, a distinctive character in Taxithelium.…”

Epiphytic Mosses in the Humid Mountain Forests of the Sierra Madre Oriental, Mexico — Species Richness, Rarity and Composition

“…Richards in 1932. According to Dixon (1935) who described the genus, the plants grow on rotten logs and lianas in forest undergrowth and form vivid green patches. The lowland rainforests of Malaysian Borneo are very rich in plant species and include several rare Malesian mosses, for example Fissidens beccarii (Hampe) Broth., and Chionoloma longifolium Dix., both of which are known from the single type collection.…”
