10/3/2005: Amazing cactus

"Did you know there was a Botany Photo of the Day?" Magilla asked while sending this image along. Noted.

IotD is proud to be one of the net's "X of the X" sites, and this "brain cactus" makes the day because it's beautiful. In a wider shot, it's not quite so beautiful, but still interesting:

BPotD explains that the brains are a "morphological variant of the species Mammillaria elongata DC., or golden star cactus. The distinct morphology of this and other brain cacti, known as cristate or crested growth, is caused by an apical meristem gone awry."

I hate it when my apical meristem goes awry.

By the way, some more techie jargon! The first image up there is another one of those images that really is hard on the JPEG format. The original from the BPotD was over 300K in size - massive. It could only reasonably compress to about half that size for the above display. (I rehost the images locally so I don't use people's bandwidth, and so that the IotD remains over time even when people's hosted images go away.) It's because of the many colors and many small but detailed shapes in the image; they don't compress well.
