Philippine Stamp: Yellow Bell (Allamanda)

Allamanda, also known as Yellow Bell, Golden Trumpet or Buttercup Flower, is a genus of tropical shrubs or vines belonging to the dogbane family (Apocynaceae).

The genus Allamanda is native to South and Central America. Their year-round production of large, bright flowers have made the Allamanda popular ornamentals.

A woody, evergreen shrub with vigorous growth, Allamanda may reach a free-standing height of 2 metres or more. The leathery leaves are lancelike, pointed, and may either be opposite or in whorls of three or four. The yellow, trumpet-shaped flowers are 5-7.5 centimetres in diameter; cultivated forms tend towards larger blooms which may also be white, purple, pink or orange in colour. Their scent may be described as delicate and fruity.

Philippines Stamp: Adelfa (Nerium)

Nerium oleander is an evergreen shrub or small tree in the dogbane family Apocynaceae, toxic in all its parts. It is the only species currently classified in the genus Nerium. It is most commonly known as oleander, from its superficial resemblance to the unrelated olive (Olea), but has many other names. It is so widely cultivated that no precise region of origin has been identified, though southwest Asia has been suggested. The ancient city of Volubilis in Morocco took its name from the old Latin name for the flower. Oleander is one of the most poisonous of commonly grown garden plants.

Philippine Stamp: Kalachuchi (Plumeria)

Plumeria (common name Frangipani) is a genus of flowering plants of the family that includes Dogbane: the Apocynaceae. It contains 7-8 species of mainly deciduous shrubs and small trees. They are native to Central America, Mexico, the Caribbean, and South America as far south as Brazil but have been spread throughout the world's tropics.

In the Philippines and Indonesia, Plumeria, which is known Cebuano and Tagalog as calachuchi, is often associated with ghosts and graveyard. Plumerias are often planted on cemetery grounds in both countries.
