This postage stamp issue presents rare flower species found in the patrimony of four botanical gardens in Romania. The stamps were unveiled on 3 July 2015.
On the stamp with the face value of lei 1.00 is illustrated Astragalus peterfii Jav, plant from the species Milkvetch, endemic to Romania and with a pin head habitat, discovered in 1916 near the Suatu village in the Transylvanian Basin. Despite its modest appearance, the species has a particular scientific value by its uniqueness, age and origin. This is found in the Alexandru BorzaBotanical Garden of the Babes ‒ Bolyai University in Cluj-Napoca, founded in 1920 by professor Alexandru Borza. The Botanical Garden is an oasis of greenery and a living laboratory in the heart of the city.
The stamp with the face value of lei 3.30 reproduces the image of Brandza’s Iris (Iris brandzae Prodan), a plant originating in Romania and bearing the name of the doctor and botanist Dimitrie Brandza. A herbaceous perennial plant, it can reach heights of up to 30 – 50 cm. Flowers are terminally located on each stem, and are 4 ‒ 4.5 cm long; they are violet-blue, have their outer perianth-segments lightly colored, with darker violet lines, and their internal perianth-segments are shorter, colored a uniform violet-blue, and strongly keeled. It is a vulnerable and rare plant in Romania’s flora, with a sporadic spread. It can be admired at the Anastasie Fatu Botanical Garden in Iasi, the oldest botanical garden in Romania, founded in 1856 by he who now gives its name, physician and naturalist Anastasie Fatu.
The stamp with the face value of lei 8.10 reproduces the image of the Romanian Peony or Forest Peony (Paeonia peregrina Mill), a plant that is endemic to Romania, endangered and rare, protected by law. The stalk can reach a height of up to 60 cm. The flowers are simple and large (up to 5 ‒ 6 cm), carmine-red in colour. Stamens are in large numbers, have red stalks and yellow anthers. The Romanian Peony beautifies and completes the living patrimony of the Botanical Garden in Galatz, founded in 1990 as a section of a new museum institution, The Natural Sciences Museum Complex Galatz.
The stamp with the face value of lei 9.10 illustrates the Cross Hale (Hepatica transsilvanica Fuss), a rare forest plant, endemic to the Carpathians, unmistakable due to its leaves. These have a long petiole and kidney shaped lamina, divided into three lobes, each divided into other three lobules. The stem can reach up to 20 cm and supports a single flower. The flowers are large and blue. It is a perennial plant that blooms in spring.
