 Perennial, native to South India and Sri Lanka, introduced elsewhere and commonly cultivated as a crop plant. \\
 Essential oil extracted from the aerial parts is the source of the commercial "citronella oil" which is used as an insect repellent. [[http://www.floridata.com/ref/c/cymb_nar.cfm]]
+Cympogon nardus is the source of **Sri Lanka-type citronella oil**, owning a warm, floral, woody odor with a rose nuance and a fresh topnote of citronellal. Main constituents of the essential oil are citronellal (5%), geraniol (20%), citronellol and geranyl acetate (14%), citronellyl acetate (3%), and limonene (9%).
+It is "...more pleasant than the [[cymbopogon_winterianus_jowitt_ex_bor|Java type]]. useful in fresh, floral compounds for all purposes." \\

 "The steam-distilled volatile oil obtained from partially dried grass (citronella grass) Cymbopogon nardus (Linn.) Rendle (Syn. Andropogon nardus Linn.), cultivated in the Nilgiri Hills at Ooty, India, was analysed by capillary GC and GC–MS. The partially dried grass contained 35 components, of which 29 constituents, comprising 92.7% of the oil, were completely identified. The oil contains 16 monoterpenes (79.8%), nine sesquiterpenes (11.5%) and four non-terpenic compounds (1.4%). The prominent monoterpenes were citronellal (29.7%), geraniol (24.2%), γ-terpineol (9.2%) and cis-sabinene hydrate (3.8%). The predominant sesquiterpenes were (E)-nerolidol (4.8%), β-caryophyllene (2.2%) and germacren-4-ol (1.5%)." \\
