Abstract

Mostly herbaceous, only three of 25 genera reach Nova Scotia. They are typified by the acrid latex contained within, which may be variously coloured. Leaves are alternate and lobed, or toothed. Regular flowers are usually showy, comprising 2–3 sepals, enclosing many stamens and up to 12 petals. They are singly carried atop a peduncle. Fruit is a unilocular capsule, further divided into as many as 20 valves. Photographs donated by Ross Hall, Eugene Quigley and Sean Blaney.
