SOME NEW SOUTH AFRICAN MOSSES

New Locality Records for Some Rare Mosses in Tasmania

There have been more than 640 species of bryophytes recorded for Tasmania, comprised of 282 hepatic species (Ratkowsky 1987) and 361 moss species (Dalton et al. 1991). This number of species is significant when compared to other groups ofland plants and, therefore, the bryophytes represent a major component of the flora (table 1). Since the publication of an annotated checklist of Tasmanian mos...

Analysis of Scale from Some South African

Several samples of evaporator scale collected during the 1993 and 1994 milling seasons were analysed using x-ray diffraction, x-ray fluorescence, scanning electron microscopy and optical microscopy. The results were evaluated in terms ofcurrent knowledgeofevaporator foulingand similar trends were found to those published in the literature. From these results, typical evaporator scale profiles c...

CHROMOSOME COUNTS IN SOME MOSSES OF IRAN

Cytological information is absolutely lacking for the Iranian moss flora (Bryophytes). The present research, dealing with cytological studies on the following five species (including two expressions and one variety) of Iranian mosses, namely, Amblystegium riparium (Hedw.) B.S.G. “brevipes” expression(n=20), A. riparium (Hedw.) B.S.G. “pennellii” expression (n=9, 9+m, 9+2m), A. serpens (Hedw.) B...
