Citrus Pages photo copyright

Citrus Pages has at present about 1500 citrus-related photos provided by over 35 institutions and individuals, many of whom have taken photos exclusively for this site. Photos may be downloaded for private use only. They may not be printed or published on other websites without prior consent of the copyright owner. I am contractually unable to give permission to use photos owned or taken by third parties and requests should be addressed to the copyright owner directly. 

I can only authorize the use of my own photos and will do so for certain non-commercial purposes. In this case a link or reference to Citrus Pages is required and the credit © Jorma Koskinen must be shown. Please send photo requests to
Citrus Pages.

The first three organisations, two in California and one in France, made it originally possible
to create Citrus Pages with their generous support and apparently inexhaustible
supply of high quality citrus photographs.

University of California, Riverside
UCR College of Natural and Agricultural Sciences

The Citrus Variety Collection of the University of California has given Citrus Pages permission to
use their photographs. The Citrus Experiment Station and its Citrus Variety Collection were
established in Riverside in the early 1900s to support the needs of the developing citrus
 industry in Southern California. Today UCR has expertise in many disciplines, yet the
Citrus Variety Collection, consisting of two trees each of more than 1000 different
citrus types, remains one of the premier citrus germplasm collections in the
world and a valuable university resource. The university retains the
copyright of their pictures, which are marked

  UCR Citrus Clonal Protection Program

The California Citrus Clonal Protection Program (CCPP) is part of the Department of Plant Pathology
at the University of California at Riverside and is a cooperative program with the citrus growers of
California, represented by the Citrus Research Board, the California Department of Food
and Agriculture and the United States Department of Agriculture. This program serves
both researchers and growers by providing a safe mechanism for the introduction
of citrus varieties from around the world and then maintains these varieties in a
protected, disease tested collection of important fruit and rootstock
varieties that serve as as a primary source of propagating
materials for California. Their pictures are marked:

French National Institute for Agricultural ResearchINRA France

The French National Institute for Agricultural Research has given Citrus Pages permission to use
the photographs of the citrus collection in their agricultural research centre in San Giuliano
 on the island of Corsica in the Mediterranean. The centre was established in 1958 and
has a collection of more than 1000 citrus types, four trees of each type, including
over 240 types of mandarin. FNIAR

varieties. It builds on the classification of Tanaka which, while not universally accepted, has the

Sorting Citrus names  

For those who are puzzled by the various Latin names of plants and especially citrus fruit
the University of Melbourne site of multilingual plant names is warmly recommended.
You will find alternative names not only in Latin but in dozens of
other languages and scripts as well.

However, those who are interested in the recent developments in the botanical names and
classification of citrus fruit should take a look at the Citrus Classification page.
Comments and suggestions are welcome.
