Phylum: Magnoliophyta - Class: Liliopsida - Order: Orchidales - Family: Orchidaceae
This orchid is one of the most common and widespread in the Mediterranean.
Ophrys lutea grows to around 40cm and each lax inflorescence can carry up to 10 large flowers. The sepals and petals are greenish-yellow and the lip of the flower has a broad bright yellow border surrounding a reddish brown centre which has a grey or blue speculum forming a W-shape. In favoured habitats this plant forms large colonies.
This orchid is reported from many southern European countries but there is much confusion with smaller-flowered subspecies. Ophrys lutea is easily recognised in the Iberian Peninsula where it is most common, particularly in the south. In the Algarve region of Portugal it is very common and occurs in large numbers. As in other areas a smaller-flowered subspecies is recorded - Ophrys lutea subsp. galilea but it is extremely rare in the Algarve but more widespread in eastern Europe where it is known by other names - Ophrys sicula and Ophrys phryganae.
Ophrys lutea grows in coastal areas in alkline substrates. Open sunny positions on abandoned farm terraces, on roadside verges and in poor grassland are good places to look.
This orchid flowers from the end of February to the end of April.
The specimens shown above were photographed in Portugal on the Algarve during March.
