 Apium graveolens L. var.dulce Mill. - (self-blanching) celery, **Stangensellerie**, with fleshy petioled leaves. \\
 Apium graveolens L. var. secalinum Alef. - Chinese celery, **Schnittsellerie**, with thin stems and leaves that are used as much as the stalks for soups etc.
+"The characteristic odor of celery essential oil is due to a series of phtalide derivatives, of which [[https://en.wikipedia.org/wiki/Butylphthalide|3-n-butylphthalide]] and [[http://www.leffingwell.com/chirality/sedanolide.htm|sedanolide]] are reported to be the major odor components." \\

 "The aroma volatiles of a local variety of celery from Libya were analysed using routine procedures... Unusually, three constituents alone made up ca 70% of the total volatiles, 4,7-dimethoxy-5-(prop-2-enyl)benzo-1,3-dioxolan or apiole (ca 23%), 3-butylphthalide (ca 22%) and 3-butyltetrahydrophthalide or sedanolide (ca 24%). The latter two compounds are known to possess strong characteristic celery aroma." \\

-The essential oil of celery and celeriac, extracted by simultaneous steam distillation-extraction, is dominated by terpenes (28-63mg/kg), with limonene as main constituent (12-37mg/kg), followed by γ-terpinene. Other characteristic compounds present are pyridine, hexanal, furfural, 3-methyl-4-ethyl hexane, and phtalides (2-7mg/kg; 3-n-butylphthalide, neocnidilide = [[http://www.leffingwell.com/chirality/sedanolide.htm|sedanolide]], [[http://webbook.nist.gov/cgi/cbook.cgi?ID=62006-39-7|senkyunolide]]). \\
