3. “to discover the taxonomic position (of a plant or animal)’ to ascertain the generic and specific names of (WIII), to identify taxonomically; determined: to be able to identify or determine the genus, species or other taxonomic category to which a specimen or group of specimens belongs; opp. indeterminatus,-a,-um (part.A), q.v.; cf. variable; see ‘infinity sign;’

NOTE: determinate growth: “growth in which the axis being limited by the development of the terminal flower bud or other reproductive structure does not continue to elongate indefinitely (as in a cymose inflorescence and in certain mosses); growth that proceeds only during part of the vegetative season and then ceases” (WIII); (bryophytes) growth that is limited, as in leafy liverworts where the apical cell is used up in producing archegonia” (Crum 1919):
