Polytrichales
Polytrichaceae is a common family of mosses. Members of this family tend to be larger than other mosses with a thickened central stem and a rhizome. The leaves have a midrib that bears photosynthetic lamellae on the upper surface. Species in this group are dioicous. Another characteristic that identifies them is that they have from 32 to 64 peristome teeth in their sporangium.

Dawsonia (plant)
''Dawsonia'' is a genus of acrocarpous mosses. ''Dawsonia'', along with other members of the order Polytrichales, are taller than most mosses and have thicker leaves. Their sporophytes have conducting systems analogous to those of vascular plants. ''Dawsonia superba'' is found in New Zealand, Australia and New Guinea. '' D. longifolia'' is found in the Philippines, Indonesia, Malaysia, and Australia. There is uncertainty as to whether ''D. superba'' and ''D. longifolia'' are actually distinct species. Etymology ''Dawsonia'' was named in honor of Dawson Turner (1775–1858), distinguished cryptogamist and friend of Robert Brown, who named the genus in 1811. Description Height Moss gametophytes lack internal transport tissues, which, coupled with the absence of cuticles, leads to the water-loss characteristic of bryophytes. As bryophytes can only grow when hydrated, the lack of conducting tissue restricts most mosses, even in relatively wet habitats, to a low stature. Ho ...

Max Fleischer (painter)
Richard Paul Max Fleischer (4 July 1861, Lipine in Oberschlesien, Kingdom of Prussia – 3 April 1930, Menton, France) was a German painter and bryologist. As a botanist, he is remembered for his work with Javan mosses. Biography He took art classes in Breslau, qualifying as an art teacher in 1881. He furthered his studies in Munich and Paris, where his interest in natural sciences grew. He subsequently moved to Zurich in 1892 in order to study geology. In the latter part of the 1890s, he was invited by botanist Melchior Treub to Java as an illustrator. On Java, along with his artistic duties, he collected regional botanical specimens and conducted investigations of the island's mosses. During his time spent in the Dutch East Indies, he also learned the technique of creating batik prints from vegetable dyes.JSTOR Global Plants (biogra ...

Itatiella
''Itatiella ulei'' is a species of moss in the family Polytrichaceae. It is the only species in the genus ''Itatiella''. The Polytrichaceae is a common family of mosses that does not have close living relatives. Its small size and the inflexed leaf apex characterize ''Itatiella ulei''. When this species grows directly exposed to sun at high elevations, it presents a similar aspect but can be distinguished based on the distal lamella cells which are single and rhombic. Description ''Itatiella ulei'' is dark green to brown 10-25mm long plant. Just like other moss, this plant divides into two parts, which are sporophyte and gametophyte. The stems are brown, straight and forming tufts. The rhizome is pale-brown and facing down on the ground. Leaves are 2.5-4.0mm long and oblong-lanceolate in shape. This plant has hexagonal-quadratic cells that are thick walled. This plant is dioicous which means gametophytes produce sperm or eggs but never both. The perichaetium that surrounds the ...

Polytrichum
''Polytrichum'' is a genus of mosses — commonly called haircap moss or hair moss — which contains approximately 70 species that cover a cosmopolitan distribution. The genus ''Polytrichum'' has a number of closely related sporophytic characters. The scientific name is derived from the Ancient Greek words ''polys'', meaning "many", and ''thrix'', meaning "hair". This name was used in ancient times to refer to plants with fine, hairlike parts, including mosses, but this application specifically refers to the hairy calyptras found on young sporophytes. A similar naming related to hair appears in Old Norse, ''haddr silfjar'', "hair of Sif", goddess from Norse Mythology, wife of the god Thor. There are two major sections of ''Polytrichum'' species. The first — section ''Polytrichum'' — has narrow, toothed, and relatively erect leaf margins. The other — section ''Juniperifolia'' — has broad, entire, and sharply inflexed leaf margins that enclose the lamellae on the upper lea ...
