The genera Racelopus Dozy & Molk., Pseudoracelopus Broth., and Racelopodopsis Thér. form a group sharing a scabrous seta and a strong trend toward reduction in size and structure of the gametophore. They are considered insufficiently distinct from Pogonatum P. Beauv., and the species are accommodated in Pogonatum sect. Racelopus (Dozy & Molk.) Touw, stat. nov., also including P. neo-caledonicum Besch. All species occur in tropical Southeast Asia or adjacent regions and grow in humid evergreen forest. Nine species are recognized that are put in two groups. One group consists of 2 species that are tall colonists characterized by complanate, anisophyllous stems. The other group consists of more or less dwarfed shuttle species. Morphology and distribution of the latter suggest that its ancestors invaded tropical Asia from the Southeast. The paper contains a historical review, a morphological survey of the group, a preliminary discussion of its relationship to other groups in Pogonatum, general notes on distribution and ecology, a key to ♀ plants, and for each species synonymy, typification of names, description, illustrations, and notes on distribution (illustrated by dots maps), ecology, and various other matters. New reductions are proposed of 12 species and 1 variety, and the following new names or combinations are proposed: Pogonatum philippinense (Broth.) Touw, comb. nov. (based on Pseudoracelopus p. Broth.), P. misimense (Bartr.) Touw comb. nov. (based on Pseudoracelopus m. Bartr.), P. iwatsukii Touw, nom. nov. (based on Racelopus acaulis Mitt.), P. petelotii (Thér.) Touw, comb. nov. (based on Pseudoracelopus p. Thér.), P. camusii (Thér.) Touw, comb. nov. (based on Racelopodopsis c. Thér.), and P. piliferum (Dozy & Molk.) Touw, comb. nov. (based on Racelopus pilifer Dozy & Molk.).

No significant interpopulation variation in chromosome size or the location of centromeres and constitutive heterochromatin could be found in Marchantia polymorpha s. lat. The karyotype of M. polymorpha L. s. lat, as well as of M. plicata Nees et Mont. and M. berteroana Lehm. et Lindenb. comprises six metacentric, two submetacentric and one m-chromosome. The m-chromosome differs in size and structure in male and female plants. The only other difference found among the populations examined is in the location of the nucleolar organizer, which is on a small metacentric chromosome in all except a Japanese specimen where it occurs on the m-chromosome. Speciation in Marchantia subg. Marchantia seems not to have involved major chromosome rearrangements. Constitutive heterochromatin, as defined by Giemsa C-banding, is present in small quantities but does not provide enough cytological markers by which to assess the hybrid status of M. polymorpha s. str., or the distinctions between M. polymorpha s. str., M. aquatica (Nees) Burgeff and M. alpestris (Nees) Burgeff.

The peristomes of twenty-one species were studied by scanning electron microscopy. These represent eight of the fourteen genera included in the Orthotrichaceae by Vitt. Among the genera studied, Orthotrichum, Ulota, Zygodon, and Schlotheimia have diplolepideous peristomes with alternate segments. The peristomes of three species of Drummondia have a 2: 3 haplolepideous cell pattern. In species of Groutiella and Macromitrium in which the peristome is not differentiated as separate teeth the cell patterns indicate that divisions in the peristomial layers during development are significantly more disorganized than in most arthrodontous mosses. The peristome of Pleurorthotrichum is diplolepideous except that the endostome segments lack a median vertical line on the dorsal surface as is characteristic of other diplolepideous endostomes. The phylogenetic significance of peristome variation in the Orthotrichaceae is as yet unclear.

The 27 species and several infraspecific taxa of Frullania (Hepaticae) are confirmed for Seram Island, in which 2 species and 4 varieties are newly described and further 19 species were not known previously from the island. The Frullania flora of Seram shows an affinity to that of New Guinea, rather than that of Malay Archipelago (excl. New Guinea). Short comments are given on phytogeography, altitudinal distributions and competitive association of the species.

The sporeling pattern of Blasia pusilla L. is typified by endosporic development, from globose protonemata through segmentation of cuneate apical cells. The exospore is not ruptured until apical derivatives which exhibit the typical merophyte divisions of the adult plant give rise to young lateral lobes and Nostoc auricles. When grown under three different light and temperature regimes, only rates of germination and development are altered. No germ tubes were formed under any of these environmental conditions, even though germ tube production has previously been reported for this taxon.

The chemical content of the lichen species Cetraria islandica has been studied. Concentration of a chloroform-methanolic extract led to the isolation of fractions containing hydrocarbons, fatty alcohols, fatty acids, keto-acids, dicarboxylic, acids, sterols, mono-, sesqui-, di- and triterpenoids, and some aromatic compounds. The C17-alkadiene, linoleic- and linolenic acid, ketostearic acid, Protolichesterinic acid and fatty acids similar to Protolichesterinic acid were found as the main constituents of the lichen extract. Most of the detected compounds are new for this lichen species. Our results also revealed some unknown constituents.

We established suspension cultures of spherical cells from the moss, Barbula unguiculata. The cells remain in an undifferentiated callus state after repeated subcultures for more than two years on a solid or in a liquid medium, which is a modification of Murashige-Skoog's medium without plant hormones. Two stable cell lines were obtained, one of which utilizes either ammonia or nitrate (NA-cells) and the other utilizes only ammonia (AS-cells). The cells of the two lines grew actively in the light with concomitant synthesis of chlorophyll, but their growth required the presence of glucose in the culture media. Their growth in the light was only partly inhibited by DCMU (dichlorophenyldimethylurea) in the concentration which completely inhibited photosynthetic oxygen evolution. Both NA- and AS-cells required the presence of an organic acid, such as that in the Krebs cycle, or the presence of CaCO3, for their growth on ammonia, but the growth of NA-cells on nitrate did not require such additions. Cells of the two lines could grow and increase their mass in the dark with definite synthesis of chlorophyll, but protonema-formation did occur during growth in the dark.
