Aotus

Elegant little greenhouse evergreen shrubs, with yellow flowers, and simple, linear-subulate leaves, revolute at the margins, alternate or nearly opposite, or three in a whorl. They should be grown in a compost of equal parts loam, sand, and peat, with a little charcoal, and the pots should be well drained. Cuttings of half-ripened wood, made in April, root freely in sand, under a bell glass.
