July 2. 74

Pinguicula

Glands come quite close up to the edge of the leaf but near the edges they are more scattered. The line where the glands begin to be thick is about (30 [illeg] 4°) =. 24 of a millimetre from the edge— = abt 1/50 in

The tracheæ end in narrow border of the leaf (which has a different structure to the rest of the leaf) by a in rounded ends which show spiral markings—

The little border with no glands is .032 of a millimetre = roughly 1/900 inch

Pinguicula Amy July 6th 74

She put flies on, on the 2nd & examined them after "much heavy rain," on the 4th

"I was surprised to see how swept the leaves were many of the flies washed quite away. & the rest under the curled edges. I had put them along the middle of the leaves, except on one leaf where I placed them on the edges, & these were safely tucked under"

July 9 74 Pinguicula lusitanica

Hartnack No 4 [sketch]

The hairs vary in their points from No a & a' to b

They project stiffly over the midrib & grate tho' very slightly under the needle

July 6 /74

Trachea of P communis vulgaris chlorophyll is chiefly collected in the bulbous endings & has a striated 1/2 crystalline look.— The tracheæ are almost all transparent—

July 10. 74 P. vulgaris treated with alcohol till it becomes rather transparent— Cells filled with minute yellow spheres chiefly round walls— Glands shrunk in a peculiar way [sketch] yellow spheres nuclei? large not so spherical & solitary in the margin

[sketch] a (a) upper row nuclei in upper row

[sketch] some bundles quite close to margin

Ppn in bundle-ending

Chloride of G— The margin is 2 rows deep thick but more than 2 wide — Oblong cells (full of purple dots like the ordinary cellular tissue has—) seem wedged in between the upper & lower l row just where they join into the zig zag cells— Glands not shrunk

They form a broken line along

Leaves, green, succulent, "oblong obtuse" Hooker
