2000 Taiwan Toxic Plants 2 Sets - Special Issue 414
On September 8, 2000, a special postage stamp series was issued: Taiwan Toxic Plants 2 Sets. They are in pristine condition without discoloration.
Toxic plants are found throughout the plant kingdom, with the majority of them spreading in rural areas, campuses, parks, gardens, and roadsides. In order to raise awareness and prevention of poisonous flowers and plants, and to avoid accidental ingestion or contact poisoning, the General Post Office selected four commonly seen toxic plants as the theme: (1) Arum lily, (2) Hippomane mancinella, (3) Abrus precatorius, and (4) Nerium oleander. They were printed as a set of "Toxic Plants Stamps," consisting of four stamps. The stamp series was planned by Mr. Zheng Yuanchun, head of the Botany Division of the National Taiwan Museum.
Here is a brief description of the designs:
(1) Arum lily: A perennial herbaceous plant resembling garlic or scallions, with purple or blackish-purple outer scales on the bulb and linear leaves. It blooms in autumn with a spadix inflorescence protected by a spathe. The petals are red with undulating edges, and the stamens and pistil are elongated. The entire plant is toxic, with the flowers and tubers being the most poisonous.
(2) Hippomane mancinella: An evergreen small tree with distinct bark patterns and abundant white latex throughout the plant. The leaves are inversely lanceolate or obovate and clustered at the end of branches. It blooms in summer with terminal inflorescences, and the fruits are oval and about the size of eggs. It is often planted as a landscape tree along roadsides but the entire plant is toxic, with the fruit being especially poisonous. There have been cases of fatal poisoning from consuming half a fruit kernel.
(3) Abrus precatorius: A deciduous climbing shrub. It flowers from spring to summer with butterfly-shaped corollas in white or pinkish colors, in raceme inflorescences. The pod is flat and elongated, bright red in color, with a cap-like black spot at the hilum, which is quite distinctive. The roots and dried stems and leaves can be used to make tea, but the seeds contain highly toxic proteins, posing a lethal risk if ingested in large quantities.
(4) Nerium oleander: A tall evergreen shrub. The leaves are arranged in whorls of three to five, leathery, narrow lanceolate or linear, with sharp tips. It blooms from early summer to early autumn with terminal corymbose inflorescences, and the corolla is tubular and bell-shaped, available in three colors: peach, pink, and white. The fruit is a cylindrical follicle with hairy seeds. The entire plant is highly toxic, and the smoke from burning the branches and leaves is also toxic.
