Aug 1st 1878. Cassia f common Greenhouse var. floribunda? & C. neglecta
Pinched & rubbed pulvinus & blades of several leaves, but only one became slightly oblique & this was a terminal leaflet of C. floribunda— So separate leaflets hardly sensitive— when leaf was shaken for 30"— The leaflets became somewhat depressed.—
(C. neglecta did the same with leaflets & shook whole seedlings, but no effect— some of leaflets in latter case slightly approached each other.)
