Flowers hermaphrodite, 4-merous. Calyx-tube slender, cylindric, 
dilated at the top, articulated below the top of the ovary and breaking 
at the articulation at the end of flowering. Petals entire or divided to 
the base into 2 or 3 narrow segments, erect, fleshy, each segment sur- 
rounded by a crown of stiff erect hairs arising from the base. Stamens 
4, inserted in 1 whorl in the upper part of the calyx-tube, almost ses- 
sile and not exserted, alternating with the calyx-lobes; anthers linear, 
Ovary sessile ; disc absent or very inconspicuous; style very slender, 
arising laterally; stigma capitate. Fruit small, dry, surrounded by 
the persistent base of the calyx-tube. Seed somewhat compressed, with 
hard smooth testa ; endosperm scanty ; embryo with thick cotyledons. 
—Shrubs or undershrubs of ericoid habit with, usually, long virgate 
branches. Leaves alternate, opposite or whorled, small, leathery, 
narrow. Flowers white, red or yellow, solitary or rarely two together
