Acis fabrei

Acis fabrei is a small bulbous perennial plant. Each bulb produces one to four narrow leaves, 2 to 5 mm wide and up to 20 cm (8 in) long, averaging around 17 cm (6.7 in). The leaves appear before the flowers. Flowering takes place in late spring with the flowers held considerably below the top of leaves. There is usually a single flower to each stem (peduncle), with six white tepals, 10–11 mm long, carried on a stalk (pedicel) 5–11 mm long. The flower bud is enclosed in a spathe that is divided into two segments. The style is slightly longer than the six stamens. The smooth black seeds are 2–3 mm long. The whole plant dies down in early summer.

As of 2007, Acis fabrei was only known from four populations in the Vaucluse department in south-east France, around Mont Ventoux and the River Nesque. All the populations are within 20 km (12 mi) of one another. Plants are found in eroded soils poor in organic matter, such as terra rossa, in rocky glades, grassy areas and under Quercus pubescens.
