Saguaro. Fasciation. White-winged dove. And Stevie Nicks.

First I encountered this photo of an absolutely awesome Saguaro cactus (at L'oeil ouvert, via).  The caption was in French, so I had to Google Translate it to find this info about the plant:

The French naturalist and historian Leon Diguet realized six scientific expeditions in Mexico between 1893 and 1913... With a few prints in the world, this picture offers a spectacular example of a species of cacti: the Giant Cardon, about 8 meters high and about 10 tons.

I still wondered if it could be a manipulated image, because these are famously-slow-growing plants - it's said to take up to 75 years to develop a single side arm.  Some take on unusual shapes; here is a cristate ("crested") crown -

- a phenomenon that occurs secondary to "fasciation":

... a condition of plant growth in which the apical meristem, normally concentrated around a single point, producing approximately cylindrical tissue, becomes elongated perpendicularly to the direction of growth, producing flattened, ribbon-like, crested, or elaborately contorted tissue. The phenomenon may occur in the stem, root, fruit, or flower head.

Wikipedia illustrated the phenomenon with a photo of a wildflower:

- and I suddenly realized that I had seen the same type of anomaly two summers ago while hiking, but had no idea what was going on -

(I had assumed it was some kind of mutation, and made plans to return to the site later in the fall to collect seeds, but didn't have a chance to go).

But back to the saguaro.  I remembered from old nature films that the major pollinators are bats:

There are a number of floral characteristics geared toward bat pollination: nocturnal opening of the flowers, nocturnal maturation of pollen, very rich nectar, position high above the ground, durable blooms that can withstand a bat's weight, and fragrance emitted at night. One additional evidence is that the amino acids in the pollen appear to help sustain lactation in bats...

- but one link also listed daytime pollinators as bees and... white-winged doves.  And, of course, I couldn't hear that without thinking of Stevie Nicks' Edge of Seventeen.  Until this moment I had always assumed that the "white-winged dove" in her lyrics was an imaginary creature (her lyrics sometimes tend to be rather mystical and obscure):

The clouds... never expect it... when it rains.
But the sea changes colours...
But the sea... does not change.

And so... with the slow... graceful flow... of age
I went forth... with an age old... desire... to please
On the edge of... seventeen

Just like the white-winged dove... sings a song...
Sounds like she's singing...
Ooo baby... ooo... said ooo

Re the genesis of this song, she was in Australia when she heard the news that John Lennon died.  She returned to Phoenix, where she was familiar with the white-winged dove.  While there she was present when her uncle John died at night, which prompted this part of the lyrics -

In a flood of tears
That no one really ever heard fall,
Oh I went searchin' for an answer...
Up the stairs... and down the hall
I did not find an answer... but I did hear the call
Of a nightbird... singing...
Come away... come now...

"The white-winged dove in the song is a spirit that is leaving a body, and I felt a great loss at how both Johns were taken..." She explains it all in this VH1 Storytellers segment, which is the best way to close this blog for the night.  The resolution isn't good for fullscreen, but you can still crank up the audio...  Enjoy.

You learn something every day.
