In fact, H. rosa-sinensis is the national flower of Malaysia. The red colour H. rosa-sinensis is selected for this purpose. Therefore, the frequent appearence of red H. rosa-sinensis in Malaysian stamps is not surprising. In 1979, a set of 7 definitive (state definitive issue) flora stamps was issued by Malaysian postal authority, and one of the flora stamps is H. rosa-sinensis (see below).
One may find that the design of Malaysia stamps to commemorate national day frequently carries H. rosa-sinensis, as such the set of stamps to commemorate 10th anniversary of Independence and 10th anniversary of formation of Malaysia (see the next two sets of stamps below).
In Malaysia, the white colour H. rosa-sinensis (Bunga Raya Putih) is a medicinal plant. The root is used for traditional treatment. The use of Bunga Raya Putih as traditional medicine appeared in a stamp issued in 1998 by Pos Malaysia (see below).
Stamps with image of H. rosa-sinensis were released from time to time to promote tourism in Malaysia (see the next two stamps below).
In 2007, Pos Malaysia issued personalised (corporate) stamps for the first time. Four different designs were issued for both the values 30s and 50s (altogether eight different stamps). One of the four designs of the personalised stamps carries an image of H. rosa-sinensis (see below).
The other countries which have issued stamps on H. rosa-sinensis are Thailand, Taiwan and Russia (see the next three stamps below).
There is another Hibiscus species which has been used as national flower for South Korea - H. syriacus. Japan and South Korea have issued such stamps on this Hibiscus species (see the next two stamps below).
Hibiscus mutabilis is depicted on a flora stamp of Thailand (see below).
One of the beautiful Hibiscus species is H. schizopetalus which is characterized by its divided petals. The shape of its petals is absolutely fabulous. Kiribati issued stamp on this species (see below).
Another common Hibiscus species depicted in stamps is H. calyphyllus. This species appeared in stamps of Tanzania, Pitcairn Islands and Zil Elwannyen Sesel (see the next three stamps).
