The Rhinegold & the Valkyrie (1910) cover and title pages illustrations by Arthur Rackham
Aloe capitata var. quartziticola is from the highlands of central Madagascar, and is one of the most cold-tolerant species from that country. Its flowers do not open first at the bottom and then progress upward like those of most aloes; upper flowers often open first. The third photo is from a couple of week back when the flowers were still in bud; at that stage they are more orange.
