Vandeae

Vandeae is a subtribe within the tribe Vandeae, a large and diverse group of orchids (family Orchidaceae). The subtribe is characterized by monopodial growth (growing from a single stem that elongates over time), often with strap-shaped leaves, and flowers frequently possessing a spur.

Characteristics

Members of the Vandeae subtribe typically exhibit the following characteristics:

• Growth Habit: Monopodial, meaning they grow from a single, continuously growing stem.
• Leaves: Often leathery and strap-shaped, arising from the stem along its length. Some species may have cylindrical or terete leaves.
• Flowers: The flowers are often showy and diverse in color, shape, and size. A prominent feature in many species is the presence of a nectar spur, a hollow extension of a floral part (usually the lip) that contains nectar.
• Roots: Aerial roots are common, enabling the orchids to attach to substrates like trees (epiphytes) or rocks (lithophytes). These roots also absorb moisture and nutrients from the air.
• Pollination: Vandeae orchids employ a variety of pollination strategies, often highly specialized to attract specific insect or bird pollinators.

Genera

The Vandeae subtribe encompasses a substantial number of genera, including but not limited to:

• Vanda (the type genus)
• Aerides
• Ascocentrum
• Neofinetia
• Rhynchostylis

Distribution

Vandeae orchids are primarily found in tropical and subtropical regions of Asia, Australasia, and Africa. They thrive in diverse habitats, from rainforests to more open woodlands.

Cultivation

Many Vandeae orchids are popular among orchid enthusiasts due to their attractive flowers and relatively easy cultivation (although some species can be challenging). They generally require bright, indirect light, good air circulation, and regular watering, allowing the roots to dry out slightly between waterings.

Taxonomy

The classification of orchids is an active area of research, and the boundaries and relationships within the Vandeae subtribe may be subject to change as new data becomes available through molecular and morphological studies.
