Water Hemclock (Cowbane)


















Cicuta maculata
Kingdom: Plantae
(unranked): Angiosperms
(unranked):Eudicots
(unranked): Asterids
Order: Apiales
Family:Apiaceae
Genus: Cicuta
Species: C. maculata


At a quick glance (or until you lean the difference) Water Hemlock looks an awful lot like Queen Anne's Lace ---on speed. (its thinner and somewhat strung out.) First time I saw it, I thought, that's weird, that Queen Anne's Lace grows odd in the shade. (It looks too, a lot like Poison Hemlock and Wild Parsley, but the latter are somewhat less common than QAL.)


As is, Water Hemlock (along with Poison Hemlock) are highly poisonous, so not a good idea to mistake for wild carrot (QAL), wild parsley, or wild parsnip.

.

QAL and Water Hemlock often grow in close proximity and in patches, with the the difference that Water Hemlock seems to prefer the shade and ditches. Along highway 64, from Conway To Mayflower, QAL seems to dominate the open eastern side of the street, while the Water Hemlock sticks to the the western, darker, ditchy, heavily shaded side. I've seen a few Water-Hemlock plants in open pasture, but they seem to be the exception. Beyond that it seems that the Water Hemlock are with us for a shorter period of time, though this year its a long- short time, given the rains.
.

Beyond that, Water Hemlock and QAL share certain structure elements. Both feature bloom clusters within clusters - called "umbels." (Bloom clusters radiating on stems) Think of fireworks, or galaxies ... breaking forth atop of a larger Firework boom. (One difference however, QAL appear to unfold into a disk, while the WH umbel pushes out, from a big-bang disk to a bulbous igloo.

.

WH are just a blast to photograph. In as much as the umbels are very dimensional (and often at various stages of growth), I have pushed the focus vector through a single plant and watched as various umble parts explode as one part sharpens then fades, reaching from cluster to cluster.

Queen Anne's Lace (QAL) Part 1






.







all pics, previous years ... The QAL should be about for another month or three, in assorted stages, but they are just now taking on the quaility of " a lot." And there will be a lot more.

Queen Anne’s Lace

Daucus carota


Kingdom: Plantae
Division: Magnoliophyta
Class: Magnoliopsida
Order: Apiales
Family: Apiaceae
Genus: Daucus
Species: D. carota

Daucus carota: http://en.wikipedia.org/wiki/Wild_carrot

Or
Wild Carrot, or Bird’s nest weed, or (my name) Chalice of Stars:

Watching a QAL in various stages of unfold is its own special treat. It starts as small unfolding wad, with just a hint of purple as the bundle unfolds. As the flower head matures it flattens, then swells, moving from the shape of small pancake, to a pin-cushion.


Then there are the blooms themselves. Like wheels within wheels. You might notice the small bloom-cluster moving away from the pack. It mirrors the overall shape of the larger flower-head.

Even weirder, after getting all big an flowery, the flower pad folds back in, going back into something of its pre-boom shape where it becomes a virtual seed nursery. (Addendum coming)
