July 17 / 1881. Smithia Pfundii

Syringed for 4' from beneath with water at 90° & leaflets rose a little, but then pressure was from below — rubbing pulvini of leaflets with needle caused very slight upward & forward movement —

Leaflets both sides protected with bloom.—

July 12' syringed from above leaf for 4' with water at 90° on plant out of hot case, & leaflets certainly rose a little & moved a little forwards or towards apex of leaf. —

July 23d — 2 Plants — 2 leaves on each plant; prepared by w 6 on each leaf (posteriorly to cut off one on each side) by washed with camel-Brush with water at 10° till leaflet well wetted. —

So altogether 12 leaflets (on right-side viewed from apex) with drops of water on, & 12 l washed leaflets with no drops. — Plants in case quite free — leaflets not pinned — Leaflets occasionally dry & occasionally wet — Leaves marked on one plant red wool on other yellow wool.

Drops put on at 11˚. 30' a.m 23d (over)

[69v]

(Smithia)

Aug 2d no effect — Drops temporarily discontinued after morning of 3d till 5th (2 days intermission)

Aug 15th I fancy that most of the leaves which have been wetted look a shade browner.

Sept. 7th I ceased putting on water, which has been continued at first 4 or 5 times & latterly 3 times daily.

Sept 11th The 12 leaves thus treated have been but little injured, yet somewhat injured, as they look a little yellower than the 12 opposite leaflets from which bloom was removed, but have not been at all wetted. —

Oct 10th of '6 of the leaflets now conspicuously yellower than the opposite cleaned ones, on which no water had been out.

3 slightly yellower than do

2 only a trace yellower

1 not at all yellower

Oct 12th. on one leaf, leaflets on both sides fallen off on 2d leaf. 2 which had water fallen off, not opposites

Oct 28 During absence of 2 days almost all leaflets fallen off & I can tell nothing.
