Wynn or Wynn cassia was registered as a variety in Queensland in 1984. The genus was originally Cassia rotundifolia, hence it derived its name as Wynn cassia. It has small seed size 253,000 seeds/kg and is high in forage yield e.g. 7t dry matter could be obtained. There is no evidence of Rhizobium specificity and it nodulates readily with cowpea inoculums. It can be readily eaten by cattle and sheep without any sign of toxicity and is remarkably free of pests and diseases. It grows well with grasses. It may have high tannins prior to maturity, thus may not be as palatable initially.
- Growth habit – it has typically ovate shaped leaflets. It is very good drought tolerant and can produce good forage in spring through autumn. The growth habit is indeterminate and can withstand grazing pressure.
- Adaptation – most suited to areas with 600mm or higher rainfall but can be damaged by waterlogging for prolonged periods. Leaves can be frost damaged, but the plant regenerates easily and makes good recovery.
Seeds are light brown, rectangular shaped and flattened laterally – up to 470,000 seeds/kg
- Bare seeds at 2-4kg/ha
- Coated seeds at 3-6kg/ha
