The "white stuff" on the leaf does not rub off on fingers like mildew would. It instead appears to be made of a number of fine hairs. And there are very small black things inside those hairs!

The first pix is is a 30X microscope view, with the camera pix through the eyepiece enlarged. I've scraped back some of the white hairs with a microscope probe, which revealed this black "surprise". The diameter of the black "surprise" is 0.25 mm. It turns out the black surprise was just minute soil particles, except for the first pix which indeed was just a hole in the leaf; see comments below.

I looked at some other leaves yesterday morning at 9:00 a.m., and when I looked at them again at 10:00 p.m. that night, 13 hours later, similar black dots had emerged from the small white hairs as the leaf dried and shrank. Those turned out to be soil particles too.

This was so cool... I turned the bend and saw a jackrabbit coming down the path. Since we were on a 10-ft. wide levee, there were only two ways to go - either forward or back. After considering it for a moment, he came straight for me and passed only a couple feet from where I was standing. So fast! So cool!

Description

Some rather scruffy-looking Common Mallow (Malva neglecta), photographed in a patch of mulch at Varian Park in Cupertino, CA. Note that there are two photographs in the set of poctures documenting this specimen - the lead shot (Shot 1.1), which provides a view of the plant in situ; and the remaining shot (Shot 1.2), which provides a closeup of one of the flowers and some surrounding leaves.

In identifying this plant, I made the following observations:

1) This specimen has bisexual flowers consisting of 5 sepals; 5 petals, a single pistil, and numerous stamens. The 5 petals are partially fused together to fom a corolla tube that is radial in its symmetry. The pistil has a superior ovary at one end 5 linear stigmas at the other. Finally, the stamens' filaments have fused together around the pistil, almost enclosing it completely. Together, all of these traits place this specimen firmly within the Mallow Family (Malvaceae).

2) This specimen is also an annual forb with axillary flowers, with up to 10 flowers per leaf axil. Inside each flower, one can see the anthers arranged in a single series near the top of the filament tube, just below the linear stigmas. Outside the flower, subtending the calyx, are three tiny bractlets that are generally free from each other (verified in the field, difficult to see in the photos). The stems of the plant are prostrate to erect. Together, all of these traits place this specimen firmly within the genus Malva.

3) Finally, for this specimen, sepals are about 4mm long, while the petals are around 8mm long (= 2x length of the sepals). The petals are white to pale lialc pink, with veins that are not darker than the base color of the petals. Together, these traits identify this specimen as Common Mallow (Malva neglecta), a non-native plant originally from Eurasia that has become more or less naturalized in northern California. It is also known as Dwarf Mallow.

Bull Mallow (Malva nicaeensis), photographed at the Stevens Creek Tidal Marsh in Mountain View, CA. Note that there are 5 photographs in the set of pictures documenting this specimen:

Shot 1 - Provides a closeup of an open flower and a recently closed one. Petals are 10mm long and about 8mm wide.

Shot 2 - Provides a closeup of a leaf (upperside only). Note that the leaves can easily reach 10cm near the base of the plant. This is a cauline leaf, so it is closer to 6cm at its broadest point.

Shot 3 - Provides a shot of one of the specimen's stems, so one can see the alternate arrangement of the leaves and the axillary arrangement of the flowers.

Shot 4 - Provides a closeup shot of the seed capsule. Note how the calyx encloses the seed capsule completely; also note how the bracts subtending the calyx remain attached to it, even as they enclose the seed capsule inside.

Shot 5 - Provides a wide shot, showing the plant in situ in its environment. This specimen is already about 5 feet tall, and I have seen other specimens of M, niccaensis get even taller.
