Oaks on Postage Stamps

The late Stelian Radu, one of the early members of the IOS, wrote an article in International Oaks no. 3 (1993) about postage stamps that featured oaks: "The Oaks in Philately." It was based on his own collection, which focused on stamps related to trees and forests, and it included some illustrations in black and white. I thought it might be interesting to update the article to include other stamps with oaks, using the research capabilities that the internet now offers, and to illustrate them with color reproductions. The project became a bit of a rabbit hole, as it turns out that in addition to the stamps that Stelian had not included, a large number of countries have issued oak-related stamps since he wrote the article. It might be easier to list the countries that haven't done so! You can see the result of the research below.

I found a total of 100 stamps that prominently featured an oak tree, oak leaves, or acorns. As might be expected, Quercus robur is by far the most philatelic oak, chosen by many European countries. But there are some interesting rarities: kudos to Costa Rica for putting the rare Q. brenesii on a stamp; a few countries have highlighted their endemic species, or at least species that would be endemic or nearly so before they were synonymized; Germany issued two poignant post-war stamps in which oaks eloquently symbolize the hope of new beginnings; an oak cultivar has made it on to a stamp (issued by Belgium, of course); and surely the prize for rarity goes to Abkhasia, who put two oak fossils on their stamps. Interesting to note that countries in oak diversity hotspots like Mexico, China, and South East Asia are surprisingly absent.

This de facto state in the South Caucasus, recognized by most countries as part of Georgia, is the only country to put Quercus fossils on their stamps: Q. kodorica and Q. sosnowskyi, both described by Georgian/Russian (Soviet) paleobotanist Alfred Alekseevich Kolakovsky (1906–1997).

One of a series of 17 stamps issued in 1936 to commemorate two thousand years since the birth of Horace. Each of the stamps includes a quotation from the classical poet's work. This stamp depicts a Q. ilex (holm oak) and an eagle, with the inscription "duris ut ilex". The quotation is taken from Book IV of Horace's Odes. The passage from which it is taken reads:

Gens, quae cremato fortis ab Ilio
iactata Tuscis aequoribus sacra
     natosque maturosque patres
     pertulit Ausonias ad urbes,

duris ut ilex tonsa bipennibus
nigrae feraci frondis in Algido,
     per damna, per caedes ab ipso
     ducit opes animumque ferro. 

It has been translated by A.S. Kline as follows:

Their race, still strong despite the burning of Troy,
brought their children, sacred icons, and aged
fathers, tossed about on Tuscan seas,
to the towns of Italy, as some oak,

rich in its dark leaves, high on Mount Algidus,
trimmed back by the double-bladed axe, draws strength
and life, despite loss and destruction,
from the very steel itself. 

Duris ut ilex

Issued in 1958, this stamp commemorates the 10th anniversary of the Italian Constitution. It shows an oak (Q. petraea?) with a vigorous new shoot, symbolic perhaps of a new beginning.

One of a series of two stamps showing "hundred-year-old trees" (the other is an Olea europea): Q. infectoria. The subspecies that is found in Cyprus is known as Q. infectoria subsp. veneris, for some authors Q. boissieri. It is difficult to make out the text on the stamp in the low-resolution image available, but it appears to say "Quercus infectoria ssp. Cyprus Oak". Cyprus oak is one of the common names of this taxon, also known as Aleppo oak, gall oak, and dyer's oak.

Dubok Russia


Issued in 1966 to commemorate the 600th anniversary of the city of Guernica. The stamp features the Árbol de Guernica (in Basque Gernikako Arbola, "Tree of Guernika"), a Q. robur that symbolizes traditional freedoms for the Biscayan people, and by extension for the Basque people as a whole. It has been replaced five times since the first was planted in the 14th century, using seedlings grown from the tree's acorns. The tree depicted on the stamp was the third, re-planted in 1860, which survived the Bombing of Guernica in 1937 but had to be replaced in 2015 because of a fungus.

United States of America

Commemorating the 300th anniversary of the state of Connecticut, this 1935 stamp depicts the Charter Oak, an unusually large Q. alba growing on Wyllys Hyll in Hartford, Connecticut in the U.S., from around the 12th or 13th century until it fell during a storm in 1856. According to tradition, Connecticut's Royal Charter of 1662 was hidden within the hollow of the tree to thwart its confiscation by the English governor-general. The oak became a symbol of American independence and is commemorated on the Connecticut State Quarter. For Connecticut's tercentennial, it was depicted on a commemorative half dollar as well as on this stamp.

Charter Oak USA

Quercus alba was also selected for one of a series of four stamps issued in 1978 featuring U.S. trees.
