Pócs, T.: New or little known epiphyllous liverworts, XI. Otolejeunea subana sp. nov. from Madagascar.

New or little known epiphyllous liverworts. 51 hexagonal, 20-25pm in diameter, with small trigones and here and there with intermediate thickenings. Lobule ovate-lanceolate, approximately twice as long as wide, 240-350 x 120-180 pm, often only in its lower proximal part, inflated. Lobule cells square or elongate quadrangular, 12 x 12-20 pm. Lobule margin in most cases visible and flat. The obsolete lobule teeth, both reduced at the same level, do not really differ from the other lobule margin cells and are recognizable from their position bordering a small, one cell deep incision, with the ovate or sausage shaped hyaline papilla. The latter is fixed to the proximal inner side of the first tooth and is directed in any side. Amphigastria are circular, the widest at their middle (10-16 cells), with slightly crenulate margin. Underleaf lobes triangular, 4-6 cells broad at their basis with the same length, ending in one rounded or triangular cell, sometimes tipped by a hyaline papilla. Sinus between the lobes quadrangular, V or U shaped, medium to wide. Underleaf base with bilobed rhizoid initial disc and with an almost straight insertion line. Rhizoids densely develop, short, colorless. Autoecious. Androecium on short lateral branches or among the sterile leaves of the main stem. Consists of 3-6 pairs of hypostatic male bracts, each with one antheridium. 2-3(-5) amphigastria develop on the lower two third of the male branch. Gynoecium on very short branches near the shoot or branch apex, with one Pycnolejeunea type innovation. Female bracts falcato-spathulate with obtuse apex, very unequal and asymmetric shaped, each with a spathulate lobule of about its half length. Bracteole ellipsoidal ovate, about 2/3 length of the bracts, with very short lobes of rounded apices and with a very narrow sinus. Perianth more or less inflated, 1 mm long and 0.75 mm wide on its top, together with the large, rounded ears. The sinus between the ears obcordate. Perianth cells in average 30 x 20 pm, but quickly diminishing towards the upper end of the ears. Seta articulate, when mature, 1000 pm long and 30-50 pm thick. Capsule slightly ellipsoid, 250300 pm wide and 280-320 pm long with -360 pm long segments. The new species is dedicated to my old friend, Professor János Suba, bryophysiologist, with whom I spent near four decades together at the Botany Department of Eger College, sharing many nice experiences and adventures, always enjoying his kind help and expertise. The new species is obviously related to some other members of the Allorgella subgenus of Otolejeunea. The closest relatives seem to be O. rabenorii Tixier in Madagascar and O. semperiana (Gottsche ex Steph.) Grolle from the Philippines.
