In sense 2 after scientific Latin acerosus ( Linnaeus Philosophia botanica (1751) iii. 42), which apparently arose from association of the Latin word with either acus needle (u- stem: see acicula n.) or ācer sharp (see acrid adj.). Compare acerote adj. N.E.D. (1884) gives the pronunciation as (æ:sĕrō^u·s) /ˌæsəˈrəʊs/.
