Mimulus Luteus Greenhouse Plants

Syringed hard on stigma of 7 flowers & none shut & when afterwards touched with needle & blotting Paper did not shut! can cold water of Temp. of room paralyze them? Temp. ─ 56º

One did shut & another partially so I tried 9 flowers.

(At 11º 25' (ie after only 35m) 6 of these flowers shut when touch with fine needle for human hair is not stimulus enough.

(12º most of them open again)

(2º 30' touched the stigma of several with damp blotting-paper all shut up well.)

(N.B during rainy weather I suppose it wd be injurious no for stigma to close over wet pollen, but there is no too good adaptation.) (Try put on water & then pollen.) (Possibly may be adaptation try cold rain)

Mimulus

May 4th The stigma considerably protected by upper part of corolla & could only be touched by obliquely driving rain, & this n never touch it with anything like forces of syringing; so I conclude that occasional closing of stigma of no more use than the closing from heat.— Moreover I put on dry pollen on stigma with drops of water & this made stigma close & they never opened again— & as corolla dropped next day I suppose were fertilised,
