These cactus have a topknot of stiff bristles that are distinctively different than the regular cactus spines. They only seem to develop when the cactus is mature. Maybe they are a sign of old age? I love the shape and color of cactus even if they don't have any flowers. I guess that is a good thing since I live in the desert.
Hi James,
ReplyDeleteThis cactus looks very unique and makes me smile.
