Description:
Bushy herb 0.7-1.2 m tall usually with a perennial rootstock, usually densely pubescent with retrorse non-glandular hairs mixed with a few erect glandular ones; leaves ovate to angularly ovate, 5-16 x 4-10 cm, almost entire, or shortly irregularly lobed, the lobes entire.
Flowers 14-20 cm long; corolla white, usually tinged pink or lavender on the limb; lobes 5, not separated by sinuses, the intervening tissue developed into 5 further short angular lobules; stigma usually above the level of the anthers (rarely equal or below).
Capsule deflexed, globose, 2.5-3.5, rarely only 1.5 cm diam. (excluding the spines), breaking irregularly; spines numerous, slender, sharp, all about equal in length, much less than half the length of the capsule; seeds yellow-brown, sometimes greyed, 5-5.8 mm long.

Uses:
Occasionally grown as an ornamental but not widely recorded as a weed. Distrib: Usually found in small populations close to gardens (sometimes derelict) where originally cultivated, especially in the Mannum-Sedan area (MU region).
Taxonomic notes:
A variable species sometimes approaching D. inoxia in characters of calyx, style length, fruiting calyx base and length of the capsule spines but always, distinguished because of the presence of non-glandular hairs and the secondary lobes of the corolla limb which are shorter than the acuminate main lobes with which they alternate.
