In science, beauty. In beauty, science. Daily.

Cleistocactus strausii

Cleistocactus strausii

Botany Photo of the Day will have brief written entries on weekends, holidays and my vacations from April through September. – Daniel

Monika F (aka monika & manfred@Flickr) is the contributor of today's photograph (original via the BPotD Flickr Pool). Thank you!

Native to high altitudes of Bolivia and Argentina, silver torch cactus will grow as tall as yesterday's BPotD, big bluestem (to 3m). An image of the tall, columnar appearance (and more information) is available via Wikipedia.


Thank you for offering the Botany Photo of the Day. =o)

I just have to comment on this strange creature. The hair and the red flowers just add to the weirdness. It looks very similar to the "old man" cactus in New Mexico. All in all, it is different!

The "Old Man" cactus is Cephalocereus senilis, no wonder it looks similar.

At first glance, I thought this was a chicken and thought, "Why are they putting animals on a botanical site?" (My computer is slow.)

Cleistocactus klay-sto-kak-tus. From Gk. kleistos [closed] and Cactus q.v., the flowers are tubular and nearly closed at the mouth. strausii strows-ee-ee After Strauss. Dictionary of Plant Names, Coombes.

High altitude cacti - very cool. I seem to remember some wonderful footage on a long ago Nova program - Hummingbirds feeding from these flowers during the day and then settling down to torpor ( to get through the sub-freezing nights. Time lapse of the morning sun moving down the spires and melting the frost as well as showing the hummers arousing from torpor. What an amazing world up there! (down here too!).
There were also some great shots of Darth Vader flying by on a chicken...

I thought it was a new improved "Dalek".

Wow what an interesting plant. At a quick look it looked like some sort of an animal. I really look forward to seeing different pictures.
Thank you for such a nice picture.


At first, I thought they were finger puppets.

Good photo, thanks !!

looks like a creature from a Dr. Seuss book. Really cool plant!

There is a debate going on that Cleistocactus with the straight edged flowers like this one is really Cleistocactus nivosus not C. strausii or are the 2 really 1 in the same. Anyone have knowledge or opinions on this? Thanks
