The "Banana" Cactus
This varlety of spineless cactus perhaps does not bear a very striking resemblance to the prototype suggested by its name; but, names aside, there is something curiously interesting about the sprangly form it has taken. It solves the problem of cactus architecture by growing horizontal slabs, then adjusting vertical ones along their upper border,-with a few along the lower border for good measure. Carried a few stages farther, this would give the plant the appearance of a modern steel skyscraper in process of construction.
