Aloes are NOTORIOUS for self pollination and cross pollination with almost blatant self-indulgence, so many garden aloes tend to be hybrids rather than pure species. Alwyn Berger distributed hundreds and hundreds when he was botanist/ Head Gardener at LA MORTOLLA, and gave away many more seeds collected from the rockeries and gardens there. While the plant illustrated shows some similarities to Aloe mitriformis its leaves look too narrow to be considered mitre-like.
