reaction to cold temperature
For the final post of this series on Cereus blooms, of the four buds two failed to fully open after the weather turned cold in late September/Early October. Here is the failed bloom from the same opening bud featured in the last Cereus posting.

soon to open
Here is a continuation of the previous Cereus posting, the ultimate macros of a bloom on the edge of opening.

evening preparation
Almost bursting open, the third of four flower buds of our Night Blooming Cereus caught one October evening just before opening. The black background is repurposed anit-weed ground cover material.
Here is a series of flash photographs at varying apertures and angles. The white rods are emerging anthers, the pollen-containing tips of long stamens seen in my previous postings of the open flowers.

Source of popular name?
In an earlier posts the popular name of this plant, “Night Blooming Cereus” was introduced as incorrect, still there must be some truth in the name, I believe it is found in the developing flower stalk and bud.
“Cereus” is from the Greek word for candle. Don’t these developing flower stalks, resemble a candle and the bud a flame?
Here’s the flower from an earlier bloom this season.

Seconds after taking this shot, at f/4, I changed the f-stop to 29 and captured these blossoms with the environment in focus (yesterday’s posting). At f/4 focus is a challenge and I was not happy with the detail of the foreground blossom.

I am in the experimentation phase of learning the new camera, so in spite of the 100% file size increase I turned on the Dual Pixel Raw feature. The two photos are from the same file. My impression is the adjustment improved the foreground flower details. Is it my imagination?
Land snail
Hepatica blossoms are the focal point here. Two land snail shells rested fortuitously below, a white and dark brown. The white shell (Scientific Name: Neohelix albolabris) is seen here. In life, the shell aperture reflective lip gives the species name, from Latin root words “albo” (white) and “labris” (lip), and the popular name, “Whitelip.” Look closely to see a series of ridges, an identifying feature apparent in this specimen. There was a live specimen in our yard, just yesterday. Busy with chores, no camera at hand.

Groupings, 1 flora and 1 dangerous
Hepatica positioned perfectly above the trail, sprouting from moss, a grouping of the plant and flowers.
Scientific Name: Hepatica nobilis var. obtusa. I found the two land snail shells this session, I identified it as Neohelix albolabris, and positioned it in this shot to lend interest. In a future posting you will see the shell where it was found.
Six unrelated young adults, all female and without masks, not following social distancing guidelines, passed as a group just before I set up for this shot. I heard them coming and made plenty of space between them and me. COVID-19 testing in Tompkins continues to find several positive cases each week.
Finding an appropriate combination of settings for this grouping was a puzzle. My goal was to bring the flowers and surrounding into focus with intermittent breezes. The f-stop needed to be high to accommodate the depth with minimal exposure duration as the flowers moved in the slightest breeze. The solution was a high ISO (2500) and f-stop (32), yielding a 1/3 second exposure (Not fast). The compromise was patiently waiting for a break in the breezes.
Just opened wind-flowers
Just opened flowers on long hairy stems, tiny anemones. A crawl and tripod we needed to capture these. The scene scale is revealed by the dried leaves from last autumn.
I call these anemones from the disputations among taxonomists. All agree there is some relationship and differ in the degree. Classifications add a designation “tribe” before genus (hepatica). Alternatively, the genus is designated Anemone instead of Hepatica . A common name for anemones is “wind-flower” for how the flower is sensitive to a slight breeze, on these long stems.
This is the first hepatica capture of the session. There was no breeze at this time and the ISO is 800, f-stop 29 (lending some definition of the background, less than I’d expect) and a relatively slow exposure of 1/4 second. The 100 mm macro lens on a tripod mounted camera.
Wildflower Groupings
Red Trillium are early bloomers, along with Hepatica. I often photograph them together. Click me for a 2019 Red Trillium post of photographs from 2007 taken in Fillmore Glen Park.
Here we have two photographs from the end of the April 20, 2020 session. I finished a series of macro Hepatica and, tired (emotionally, not physically) and not wanting to step up the slope, captured the following grouping of a single Red Trillium, lit by a bolt of sunlight, White Hepatica, fern and the budding White Trillim from yesterday’s post. Not the same trillium, a continuation of all the individuals in bud.
These were 15 feet or so up the slope above the South Rim Trail. I used the 100 mm macro lens, with the spring breezes ISO set to 2500, f/5.6 for a 1/200 exposure.
Not far away, also upslope, was this flower grouping against a moss covered log. Park forestry leaves fallen trees in place to return to the soil. Camera settings are the same.
