the Danish surname Jessen is probably the origin, although there's also at least one town named Jessen in Germany. There is a botanist
Karl Friedrich Wilhelm Jessen (1821-1889) who describes a number of species in
Deutschlands Graser und Getreidearten 1863.
Gustav Karl Wilhelm Hermann Karsten (4 years older than Jessen) describes the palm as
Jessenia in 1857 in the journal
Linnaea; Ein Journal für die Botanik in ihrem ganzen Umfange. Jessen published 45 names to Karstens 701
