Surrounded by water on all sides, Taiwan, although having a land area of only 36,000 square kilometers, has great diversity of topography and climate. With the different combinations of topography and altitude, tropical, temperate zone and arctic plants can all be found here. According to statistics, there are over 4,000 native vascular plant species (including ferns and flowering plants) in Taiwan, which make it a botanical treasure trove. In order to raise understanding and consciousness about the importance of conserving these native species, Chunghwa Post has asked Cheng Yuan-chun, the head of the Department of Botany at the National Taiwan Museum, to plan a set of three stamps on Taiwan's native flowers. Two stamps will have the denominations of NT$5.00, and the remaining one a denomination of NT$12.00. The designs of the stamps follow:
(1)Ludwigia octovalvis (NT$5.00):
Ludwigia octovalvis, a wetland member of Onagraceae, is an annual/biennial aquatic plant that can be found throughout the lower altitude areas of Taiwan in wetland habitats such as rivers, swamps, ponds, lakes and rice paddies. The plant has a woody base, which often gives it a shrub-like appearance. The leaves are linear to nearly ovate. It bears yellow flowers throughout the year.
(2)Hygrophila pogonocalyx (NT$5.00):
A member of Acanthaceae, Hygrophila pogonocalyx is a perennial aquatic plant. It has erect square columnar stems and lanceolate leaves in opposite pairs. Its flowers have light purple labiate corollas. It flowers from the middle of fall to early spring. In the entire world, wild stands of Hygrophila pogonocalyx exist only in the lower altitude areas of central and southern Taiwan.
(3)Titanotrichum oldhamii (NT$12.00):
A member of Gesneriaceae, Titanotrichum oldhamii is a perennial plant native to Taiwan. It is a common sight in rockery and by mountain creeks in humid low- to middle-altitude areas throughout the island. Titanotrichum oldhamii has elliptical or narrow ovate leaves that are tapered at the ends. In late fall it blooms yellow bell-shaped flowers one after another. The throat of the flower has dark brown nectar guides.
