Melilotus Taurica — Little shoots at base of stems of last year shoot, with very small leaves looking like a clover.— The terminal leaflet turns up so as to stand vertically & only in 1 case was it turned at all laterally; the 2 lateral leaflets turn upwards, so as to stand vertically but do not touch — sleep much more like a clover than in Melilotus — Mem. case of M. messanensis.—

Feb 16. observed in Hot-House again & case is true.

Mel.

Mel. macrorrhiza & petitpierreana — young leaves go to sleep only in part like the mature ones, & some of the smallest like clovers.
