Did you know?
The genus Lechea was named by Linneaus for Johan Leche (1704-1764), a Swedish botanist who taught in Finland. He is regarded as the father of meteorology and space research in Finland for his early measurements of air temperature (at the suggestion of Anders Celsius) and documentation of the northern lights. So the next time you are looking at Lechea on a hot day think of Dr. Leche. The species name refers to the very long narrow leaves of the basal shoot.

State Ranking Justification [-]
There are 18 existing populations but only four of these are in good condition with substantial numbers for good viability. Five populations need to be resurveyed to obtain more information about condition and numbers. There are seven historical occurrences.
