The Epacridaceae is one of the families that dominate Australian heathlands, environments prone to disturbance events such as fire and seasonal drought. To investigate the role of fire-related cues in breaking seed-dormancy mechanisms in the Epacrida

The leaf epicuticular waxes of all genera within the Epacridaceae have been studied. Amorphous wax and three structured wax types, namely plate, ribbon and tube wax are described and their occurrence within genera surveyed. The distribution and devel

A geographic survey of 14 south-west Tasmanian sedgeland-heaths revealed that soil organic matter is related to: water content: total nitrogen (N): total and exchangeable sodium (Na), calcium (Ca) and magnesium (Mg); exchangeable potassium (K) cation

The sequence of anthocyanin accumulation during flower development in four flower-colour mutants of Pisum and in Lathyrus odoratus var. Chloe, shows a progression from methylated to unmethylated anthocyanidins, and the replacement of 3- O -rhamnoside

The diagnostic character set used in erecting the two species Ranunculus decurvus and R. concinnus, when applied to a wider collection of specimens, does not separate them unambiguously. These characters are variable, subject to habitat modifications

Cyanidin 3-glucoside has been identified in five species of Podocarpaceae. In addition, pelargonidin 3-glucoside was isolated from Microcachrys tetragyna Hook., and cyanidin 3-rutinoside from Podocarpus lawrencii Hook.

Estimates have been made of the quantitative contribution of each of the determinant factors, photoperiod, vernalization, and colysanthin (a presumed inhibitor of flower initiation formed in the cotyledon), in regulating flower initiation in the late

Changes in soluble protein and in peroxidase, esterase, and amylase enzymes during development of the pea plant (P. sativum) have been investigated using a horizontal method of acrylamide gel electrophoresis. Both qualitative and quantitative variati

Investigations of the flowering behaviour of peas led Paton and Barber (1955), Sprent and Barber (1957), and Barber (1959) to propose the presence of a mobile flower-delaying substance, "colysanthin", in cotyledons of late-flowering varieties. Moore
