In botany, relating to or having the characteristics of structures with ten seeds or seed-bearing components.
From the prefix 'deca-' (ten) combined with 'sperm' (seed, from Greek 'sperma') plus '-al' (relating to). This botanical adjective emerged in 19th-century descriptive botany.
Seed count is one of the oldest ways botanists classify and identify plants—noticing that a fruit is consistently decaspermal helps distinguish similar-looking species and reveals evolutionary relationships since seed production reflects deep biological differences.
