sumatrae

Sumatrae is a linguistic form derived from Sumatra, the Indonesian island. In Latin, Sumatrae most commonly appears as the genitive singular of the proper noun Sumatra, used to indicate origin, possession, or association in phrases preserved in Latin texts. It is not an English name for a place or people, and there is no modern administrative or political entity known as Sumatrae.

Beyond Latin grammar, the sequence Sumatrae may appear within taxonomic or historical nomenclature as a descriptive epithet indicating that a specimen or feature originates from Sumatra. In such cases, sumatrae functions as a Latin gloss rather than a distinct term; modern taxonomic practice typically uses "Sumatran-" or "Sumatrensis" as the expected epithet in English-language works, depending on the gender of the generic name.

Because it is a grammatical form rather than a separate concept, Sumatrae is usually encountered only in scholarly, historical, or linguistic contexts rather than in everyday use. For further information about the island itself, see Sumatra.
