July 15. 1879— Lupinus luteus

A large no of young plants in 2 Pots — most of them with 2 to 4 leaves & each of them usually with 5 leaflets: — leaflets horizontal at noon— at 9°30' P.m, leaflets all upturned, but the longer leaflets on external side of leaves are more vertical (& many quite vertical) than the shorter & inner leaflets— no trace of bending at summit of petiole, which & base of each leaflets is yellowish, as if forming a pulvinus.— The leaflets can hardly be said to have sub-petioles, for narrow lamina extends to their bases no hardly the base of each is yellowish & may be considered as a kind of subpetiole: I think the cells are here rather smaller— get F. to see— in Spirits a very rudimentary pulvinus, if it can be so called.— If there is any zone of smaller cells on summit of main petiole it is very narrow one.
