* So named by Scopoli, in honour of his learned friend Leonard Sesler, 
a Physician and Botanist, who contributed to Vitaliano Donati’s Natural 
History of the Adriatic Sea ; published in 1750. The species, eight of which 
are enumerated in Loudon’s Hortus Britannicus, p. 29, were formerly part of 
the genus Cynosurus. See Loud. Encycl. of Plants.
