Vegetatively this plant looks different from the other forms of Aloe capitata, particulaly as it ages. But even when young, this one tends to have shinier greener leaves and is definitely a slower growing plant, requiring I think full sun to be truly happy while the other forms will grow happily in some shade. As it matures, it develops a trunk, up over 5' tall (up to 12' in Madagascar), though at current rate of growth in my garden I dont really expect to live long enough to see much of any trunk at all. It is a nice, attractive seedling, though.
2011 Aloe of Madagascar book gives this a new species, Aloe cipolinicola, which makes a lot of sense to me.

This species doesn't thrive in excessive heat like that experienced in the Phoenix area during the summer. It seems these higher elevation Malagasy Aloes (inexpectata, droseroides, pronkii, conifera, madecassa, capitata var. cipolinicola, cryptoflora, etc.) suffer "heat rot" when the temperatures are consistently at, near or above 110 degrees. They're used to cooler temperatures in their native habitat and tend to fail after a few years unless kept indoors or in a greenhouse with a cooling system in Phoenix. It will love California much more!

A. cipolinicola has been elevated to species status. It is a tree aloe. I have grown this from seed here and it is a great plant. it flowers in cold wet months and is brought into greenhouse when it is flowering.
With light the leaf margins are bright red with armor. The flower is capitate form.
Aloe ballyi (the "rat aloe") is a species of flowering plant in the family Asphodelaceae, native to Kenya and Tanzania.
This species of Aloe forms tall, slender stems of up to 6 meters. The leaves are long, slender, and mostly straight - only recurving slightly towards the tips. Dead leaves do not long remain on the stem, unlike in the case of most aloes. Unlike most aloes, the "rat aloe" is poisonous. 
The flowers are only mildly tubular, with their segments united for 1/3 of their length.
It is native to the Eastern Arc Mountains and coastal forests of Kenya and Tanzania. This rare aloe grows in the bush with acacias and succulents.

Tall East African tree aloe, usually unbranched, to nearly 20 feet with advanced age. Leaves are channeled and recurved on older plants, and they give off a smell reminiscent of rats or mice when broken. Inflorescences are multibranched, often re-branched, with bicolored flowers that are red in bud and turn yellow when they open.
This is one of three poisonous aloes from East Africa (along with ballyi and ruspoliana) with this particular odor and toxic leaf sap containing alkaloids. Of the other two plants, ballyi is most similar at a distance, also being a generally solitary tree, though it differs in various floral and fruit features. The inflorescence of A. ballyi is somewhat oblique (not erect), the flowers are red or red-orange (not yellow when they open), and the fruit is shiny (not dull).
