Uromyces limonii, aecia, on Limonium humile

Uromyces limonii, aecia, on Limonium humile, enlarged view

An autoecious rust on Limonium species (sea-lavenders), pictured here on Limonium humile (Lax-flowered Sea-lavender). Its hosts are primarily coastal, the more common species being in saltmarshes, and this is necessarily the distribution of the rust. However, it is also recorded inland on cultivated members of the genus. It is reputedly scarce but may be overlooked.

Shown here is the aecial stage, on discrete red to red-brown, swollen spots that tend to extend along the main vein, on leaves in mid-summer. The brown uredinia and black telia occur later in the year.

Photographed at East Head, Sussex, 1986.
