This splendid plant came up among some Mexican 
seeds presented to the Horticultural Society by J. S. 
Mill, Esq. 1 i 
Its appearance was so entirely that of Zinnia violacea, 
that till it lowered its beauty was not suspected; and this 
unfortunately took place at so late a period of the recent 
rainy, sunless season, that we fear no good seeds of it were 
saved. hb o»

* Named in honour of John Gottfried Zinn, a- professor of Botany at 
Góttingen; born in 1727, died in 1759. He is chiefly remarkable for 
having made some experiments to ascertain the cause of the irritability of 
plants. He asserted that the leaves of Desmanthus virgatus would move 
exactly the same in a damp, cold, dark cellar, as beneath the influence of 
the sun; whence he concluded it to be a vital phenomenon.
