摘要:

SUMMARY1The main taxa of the genusDactyliaare surveyed, illustrating the range of species and subspecies occurring in the group.2The phenotypic characters in nineteen populations, including diploids and tetra‐ploids, were analysed in detail; there were large genetic differences between the populations.3The within‐population correlation of characters was studied and found to vary independently.4The heritability of some taxonomically‐important morphological characters was measured, e.g. panicle length, flag‐leaf length, and lemma apex. Each was highly heritable, and capable of independent response to selection.5The between‐population correlation of morphological characters was studied. The components of panicle size, flag‐leaf length, and lemma apex were related, showing a similar trend in diploids and tetraploids.6The significance of the trend of variation is discussed in relation to taxonomy an

SUMMARYOn the basis of further investigation and literature previously unobtainable, the correct names and synonymy of certain palmelloid planktonic green algae is considered to be as follows:1Coenococcus planctonicusKorsh. (Radiococcus planctonicusLund.).2Coenococcus pelagicus(Teil.) comb.nov. (Radiococcus pelagicaTeil.).3Cecidochloris adnata(Korsh.) comb.nov. (Chlorophysema adnataKorsh.;Cecidochloris stichogloeaeSkuja).4Gemellicystis neglectaTeil. non Bourr.(Tetraspora imperfectaKorsh.;Gemellicystis neglectaTeil. sensu Bourrelly (1959);G. lundiiBourr.).5Gemellicystis planctonica(Woronich.) comb.nov.

摘要:

SUMMARYPycnolejeunea, in recent years, has become an admixture of species belonging to diverse genera:Nipponolejeunea, Tuyamaella, Cheilolejeunea, SiphonolejeuneaandStrepsilejeunea.Its history, delimitation and affinities, at times remote, to these genera, have been discussed. An analysis of the various species of‘Pycnolejeunea’recently monographed by Hoffmann (1935) shows that the large majority of these species do not belong toPycnolejeunea, but demonstrate unmistakable affinities withCheilolejeuneaemend. Schuster (1955); these species have been accordingly transferred toCheilolejeunea, under subgenus nov.Xenolejeunea.BothPycnolejeuneas.str. andCheilolejeuneasubg.Xenolejeuneashow remarkable variation in their stem anatomy and the form and structure of lobule, and this has necessitated their division into several sections; such variation within each genus is discussed.A similar study of the remaining species of‘Pycnolejeunea’sensu Stephani et Hoffmann is de
