“…Similarly,J. colorata forms patches of red or brown gametophytes when growing on exposed rock faces, but green patches are found in the shade (Grolle 1971;Allison & Child 1975). The genetic and/or environmental basis for these colour polymorphisms is unknown, and nothing has been documented of the chemical nature or histological location of the red pigment involved.…”

Gametophytes of Jamesoniella colorata (Jungermanniaceae) and Isotachis lyallii (Isotachidaceae) produce red leaves in exposed habitats, but green leaves in shaded environments. To understand the functional significance of this colour polymorphism, the anatomy, pigment composition, optical properties, and kinetics of chlorophyll a fluorescence were compared for red and green gametophytes. Both colour morphs were structurally similar, but the red leaves held unidentified red pigment(s) firmly associated with the cell wall. Green morphs contained more chlorophylls and carotenoids, and had higher ratios of chlorophylls to carotenoids, than did the red morphs. Red leaves absorbed 10% more photosynthetically active radiation, with a maximum at 540 nm, than did the green leaves. Under high irradiance, the red leaves maintained higher apparent quantum efficiencies for photosynthesis, and had larger photochemical and non-photochemical quenching values. The data indicate that red gametophytes have the greater potential to mitigate the damaging effects of high irradiance.

“…The type of G. schizopleura originates from Madagascar (Spruce 1885). Grolle (1968Grolle ( , 1971 lowered several (Austral-)asian taxa to synonyms of G. schizopleura. If two species are actually at hand, the basionym Jungermannia colorata d microphylla Nees should be picked up to name the Asian populations.…”

Transfer of Gottschelia grollei, G. patoniae and Scaphophyllum speciosum to Solenostoma based on chloroplast DNA rbcL sequences

et al. 2009

Maximum parsimony and Bayesian analyses of a chloroplast DNA rbcL dataset indicate a position of Gottschelia schizopleura in Scapaniaceae (Jungermanniales suborder Cephaloziineae). Gottschelia grollei, G. patoniae and Scaphophyllum speciosum are nested in Solenostoma (Solenostomataceae, Jungermanniales suborder Jungermanniideae) and are transferred to this genus. Accessions of G. schizopleura from Africa and Asia are separated by long branches.

IUCN: A decline of populations has occurred in at least part of its distribution area, and more than 20% of its populations have probably disappeared within the last 30 years (three generations).…”
