Judul: The Biodiversity of Hornwort (Anthocerotophyta) in Mount Slamet
Abstrak: Hornworts (Anthocerotophyta) are one of the three divisions of nonvascular plants. Hornworts are easily recognized based on the structure of thalloid gametophyte so that it is similar to the thalloid liverworts, but hornworts generally have cells with 1-8 chloroplasts per cell, and a long cylindrical sporophyte structure similar to horns. Hornworts are generallly found in open and humid habitats such as along the edges of hiking trails in mountain forests. The hornworts in Java to date are reported to number 28 species, however only one species has been reported occurs in the area of Mount Slamet, Central Java. This research was conducted to inventory diversity, providing the key identification and description of the hornworts species of Mount Slamet. Specimens of hornworts were collected along the hiking trail of Mount Slamet in three locations, namely Baturraden (Banyumas Regency), Gunung Malang (Purbalingga Regency), and Guci (Tegal Regency). Morphological and anatomical observations of tha specimens are carried out for the purposes of species identification. Characters in the gametophyes and sporophytes are used to develop keys and descriptions of species found in the area of Mount Slamet. The observed specimens are deposited at the Herbarium Bogoriense (BO). The gametophyte of hornworts species found in this study have thallus varied from small to large, either rosette or strap-shaped, light green to dark green. The transverse section of talus has parenchyma tissue with mucilage cavities or solid (without mucilage cavities). The cells of the talus have 1-8 chloroplasts per cell with or without pyrenoids. The sporophytes have a short to long involucrum with a smooth to rough surface, the capsule when ripe is black or yellow to orange red, the stomata on the epidermis of the capsule wall are present or absent. Spores are either unicellular or multicellular; grey to black, yellow in color or hyaline; with or without chloroplasts. The distal and proximal surface of spores have various ornamentation. Triradiate markings on the proximal surface of spores are prominent or obscure. Pseudoelaters are linear, either unbranched or branched, or in the form of spiral bands, consisting of 1-5 short or long cells, and either hyaline to brown in color. The identification of 120 hornwort specimens from Mount Slamet yield six species. One of them, Dendroceros difficilis, has previously been reported found in Baturraden Mount Slamet and was rediscovered in this study. Accordingly, the other five species, namely Anthoceros punctatus, Folioceros fuciformis, Phaeoceros carolinianus, Phaeoceros exiguus, Dendroceros difficilis, Megaceros flagellaris are new records for Mount Slamet. In fact, one of them, Phaeoceros exiguus, is a new record for Malesia. All of the hornworts species of Mount Slamet, except the epiphytic Dendroceros difficilis that found on tree bark or braches, are found on various terrestrial substrates such as soil, rocks, roots and trunks of dead trees in various moish habitats which has slightly closed canophy such as in mountain forests, or in the open vegetation such as around the waterfalls, along the banks of streams, and agricultural land., Lumut tanduk (Anthocerotophyta) merupakan satu dari tiga divisi tumbuhan tidak berpembuluh.

Abstrak: Tropical forests have higher diversity of bryophytes species than other regions in the world. Diversity and abundance of bryophytes depend on the altitude. This study aims to inventory the diversity of bryophytes of Mount Lawu and their distribution based on the altitude and type of substrate. Sampling was carried out along a hiking trail of Cemoro Sewu. Total of 85 species (34 families, 56 genera), consist of 55 species of mosses (17 families, 35 genera), 28 species of leafy liverworts (15 families, 19 genera), one thalloid liverworts, and one hornworts species were found in the study. Dicranaceae (19 species, seven genera) and Bryaceae (eight species, four genera) have higher much of species. Those mosses were found mostly terrestrial growing on rock substrate. Bryophytes distribution evenly on upper mountain zones as well as at sub-alpine zone. The diversity of leafy liverworts more higher in the mountain zone (2000-3000 masl) than in sub-alpine zone (3000-3265 masl).
