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. ─ 56°

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

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

(12° most of them open again)

(2° 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)

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,
