Matilda has been evaluated in field trials in Victoria, South Australia, New South Wales, and Western Australia. Cultivar development in Victoria consisted of seed multiplication after limited roguing of off-types, based on plant and seed morphology. Matilda is a lentil of the subspecific macrosperma type and is recognised as a green, brown, or yellow lentil. It has a semi-erect growth habit during the vegetative phase. Matilda may show slight anthocyanin pigmentation in the stem, which is somewhat square and can be ribbed at the angles.
Leaves are pinnate and occasionally end in a rudimentary tendril.
Flowering is indeterminate. Seeds are biconvex with a uniform light green to very light brown testa colour without marbling or speckling. Cotyledon colour is pale yellow. Matilda has been evaluated in field tests in Victoria since 1988. Matilda has outyielded the standard green lentil cv.
