Abstract:
ABSTRACT Dicranoloma reflexum and Dicranella coarctata are mosses from Dicranaceae family. This study was purposed to identify bioactive compounds contained from both species. Dicranoloma reflexum and Dicranella coarctata collected form Cangar forest, Batu, East Java. Mosses was rinsed, dried and crushed into powder. Extraction was performed using maceration method with n-hexane, acetic acid, and methanol solvent. Compounds obtained then identified using Gass Chromatography Mass Spectra. Result showed that n-hexane, acetic ethyl, and methanol extract of Dicranoloma reflexum contained 61, 16, and 58 compounds respectively. Main component of each extract was 1-octadecene, phenol, and 9-octadecanoic acid. N-hexane, acetic ethyl, and methanol extract of Dicranella coarctata contained 5, 38, and 23 compounds respectively. Main component of each extract was thiosulphuric acid, E-15 heptedecenal, and n-hexadecanoic acid.Key words : Dicranaceae, bioactive compounds

D. austroscoparium, D.�diaphanoneuron and D. leichhardtii are endemic to Australia, while D. plurisetum and D. obesifolium are endemic to New Zealand. Moreover, D. platycaulon, D. fasciatum and D. trichopodum are endemic to the region. D. daymannianum and D. fasciatum are newly reported from Australia. All recognised species are described and illustrated and distribution maps and a key to the species have been provided.

Abstract:
The Holomitrium-complex (consisting of Holomitrium, Eucamptodontopsis, and Schliephackea) is a group of closely related genera in the Dicranaceae characterized by five features: 1. a strong single costa, 2. well developed alar cells, 3. long, sheathing perichaetial leaves, 4. erect capsules, and 5. undivided peristome teeth. Holomitrium sinuosum is newly described. Dicranoloma brittonae is transferred to Eucamptodontopsis. Holomitrium standleyi is a synonym of H. arboreum. Breedlovea chiapensis is a synonym of Holomitrium pulchellum and the genus Breedlovea is placed into the synonymy of Holomitrium.

Abstract:
Populations of Dicranoloma billardierei (Brid) Par., D. dicarpum (Nees.) Par., D. menziesii (Tayl.) Par. and D. platycaulon (C. Muell) Dix, from two pockets of cool temperate rainforest within the Yarra Ranges National Park (Cement Creek and Myrtle Loop), were sampled for a period of two years to establish their reproductive biology. The population dynamics within quadrats of D. billardierei, D. menziesii and D. platycaulon at Cement Creek also was investigated over a two year period, through the seasonal recording of shoot loss and/or gain, The four species of Dicranoloma were dioicous and sexually dimorphic, with dwarf males epiphytic on the female plants. Antheridia were initiated before archegonia and required ca, 6 months to reach maturity, compared with 1 to 2 months for archegonia. More archegonia than antheridia occurred per inflorescence and were more variable Fertilization occurred during winter in D. billardierei and summer/ autumn in D. menziesii and D. platycaulon. The duration of the sporophyte cycle of D. menziesii was 12 months, shorter than that of D. billardierei and D. platycaulon which lasted for a period of 18 months to 2 years. In the latter two species an overlap of sporophyte generations occurred. This was particularly pronounced in D. billardierei as sporophytes remained in the swollen venter maturation stage for a period of 6 months. The duration of the sporophyte cycle could not be ascertained as few fruiting stems of D. dicarpum were found. All four species of Dicranoloma regenerated from fragments cultured in the laboratory, and only two of the species showed evidence of production of asexual propagules in the field. Dicranoloma dicarpum was found to produce gemmae, an observation which had not been recorded before, and most of the leaves on stems of D. platycaulon had detached subulas. Shoot loss was minimal in all four species, and when it did occur, (eg D. billardierei) it was attributed to disturbance by animals. Within quadrats there was an increase in shoot density which resulted from the development of innovation(s) and/or side branches rather than from the recruitment of new plants from spores or the regeneration of asexual propagules. The four species of Dicranoloma investigated were robust, perennial mosses and formed an important component of the bryophytes found within the study area. Dicranoloma menziesii was the predominant species establishing on a variety of substrata, particularly as an epiphyte on Nothofagus cunninghamii The other species were more selective in their choice of substratum. Dicranoloma platycaulon was found exclusively on the trunks of myrtle beech and D. billardierei on fallen logs and exposed roots. Dicranoloma dicarpum which was not common, grew as an epiphyte on myrtle beech and on rocks.
