The most common way of naming is referring to a plant feature, often reproductive characters. Eponyms, chiefly commemorating men, have always been common and even became dominant in the last two decades.

Almost half of the names appeared in the 19th century, but the proportion of accepted names increased over time. The average number of new generic names is 5.05 per year.

Europeans authored the vast majority of names and, within Europe, it is concentrated in France, the UK, and Germany.
June 16, 2025 at 1:35 PM
A mere 1.80% of the generic names were published by female authors only.

Every letter of the alphabet has been used but P is the most popular letter to start a genus with, while Q has only been used once. These are also other most and least used first letters in the English language.

Generic names are between 3 and 20 letters long and the distribution is a displaced Poisson distribution. The median length is 10 letters. This is the same for words in European languages.

Rubiaceae has 1386 generic names, of which 615 are accepted and contain 14,266 species. This makes it the fifth-largest angiosperm family.

I present the first ever survey of all generic names in the Rubiaceae plant family.

However, the Latin caelum can also mean "vault of heaven", referring to the celestial vault in ancient cosmology. So, the original spelling does refer to the arched seeds and is therefore correct.

The name is derived from Latin caelum (=heaven) and sperma (=seed) but this does not make much sense. So, taxonomists changed the spelling and etymology: from Greek koilos (=hollow), referring to the concave seeds.

Caelospermum is the original spelling of this #Rubiaceae genus but the variant Coelospermum is more often used. However, this is wrong...
