The Lycaste skinneri var. alba is the national flower of Guatemala, this flower is also know as the Monja Blanca or The White Nun Orchid.
Lycaste flowers, like all orchid blooms, have three petals and three sepals. The petals are typically yellow, white, or orange, and the sepals are yellow, orange, green, or reddish brown. The petals and sepals may be marked sparsely or densely with red, reddish purple, purple, or reddish brown spots. The lip (ventral petal) may be very similar to the other two petals, as in Lycaste aromatica or Lycaste brevispatha, or colored quite distinctively, as in several subspecies and varieties of Lycaste macrophylla. Most Lycaste flowers are medium in size, averaging about 5 to 10 cm, but Lyc. schilleriana is 16-18 cm across. Some Lycaste blooms have a unique fragrance - the scent of Lyc. aromatica has been variously described as cinnamon or clove. The blooms of the species Lyc. cochleata, consobrina, and cruenta also have a pleasant scent.
This orchid is a rare flower in the Verapaz district of Guatemala, symbolizing peace, beauty and art. A decree by General Jorge 1, in 1934 made the white nun as the national flower. Since then its commercialization has been prohibited.
