Pieter Groenhart
Pieter Groenhart (February 21, 1894 – November 3, 1965) was a Dutch lichenologist known for his research into tropical Asian lichens. Born in Ilpendam, he became a teacher in 1916 and taught in several local elementary schools. In 1926 he moved to Java, where he became a teacher at the Agricultural School in Malang, from 1926 to 1932. Soon after, he studied biology at the University of Utrecht (1932–1935), and then started to study lichens at the Rijksherbarium in Leiden, from 1935 to 1936. He returned to teaching in Malang until 1940, when he was transferred to a Government school at present-day Bogor. In 1942, Groehnhart was imprisoned in an internment camp, where he stayed until his release in 1945. After returning to the Netherlands, he continued his studies of lichens, becoming especially interested in the genus '' Cryptothecia''. Species named in his honor include '' Ocellularia groenhartii'' (Hale 1975), '' Cryptothecia groenhartii'' (Makhija & Patw. 1994), and '' Rino ...

Cryptothecia Groenhartii
''Cryptothecia'' is a genus of white to greenish crustose lichens that grow on bark, wood, or leaves. in tropical or subtropical areas worldwide. It has a conspicuous prothallus that develops around its periphery which can be bright red in some species, hence the common name wreath lichen. The main vegetative body (thallus) lacks a cortex (ecorticate and is often immersed in the substrate or byssoid (whispy, like teased wool). The medulla is white, well defined, and often peppered with calcium oxalate crystals. Ascomata are not well defined, being cushions of soft white mycelium immersed in the medullary tissue, hence the name from the Greek ''krypto'' = "to conceal" and ''theke'' = "a container or sheath". There are about 45 described species in the genus according to one source, and 75 species according to another. The genus is in the family Arthoniaceae. It contains '' Trentepohlia'', a green alga, as its photobiont partner. Two species have been described in North America.B ...

Lichen
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms .

They come in many colors, sizes, and forms and are sometimes plant-like, but are not s. They may have tiny, leafless branches (); flat leaf-like structures ( |
Internment Camp
Internment is the imprisonment of people, commonly in large groups, without charges or intent to file charges. The term is especially used for the confinement "of enemy citizens in wartime or of terrorism suspects". Thus, while it can simply mean imprisonment, it tends to refer to preventive confinement rather than confinement ''after'' having been convicted of some crime. Use of these terms is subject to debate and political sensitivities. The word ''internment'' is also occasionally used to describe a neutral country's practice of detaining belligerent armed forces and equipment on its territory during times of war, under the Hague Convention of 1907. Interned persons may be held in prisons or in facilities known as internment camps (also known as concentration camps). The term ''concentration camp'' originates from the Spanish–Cuban Ten Years' War when Spanish forces detained Cuban civilians in camps in order to more easily combat guerrilla forces.
