Crassifolia is quite capable of producing leaves that are 36” long and 30” wide on 36” long petioles. The leathery, deep green leaves (paler on the lower surface) are distinctive not only for their size and shape but also because of their prominent veins. The midrib and numerous primary lateral veins are distinctively raised and this pattern is accented by a massive network of recessed veinlets between the primary veins which result in a somewhat blue effect. On the lower surface (clearly visible because the plant holds its leaves erect), the pattern is even more prominent because the midrib and primary veins are yellowish-green and the veinlets are raised. The basal lobes (12” long and 12” wide on a 30” long leaf) are almost square. The margins of the leaf are very slightly undulated and revolute. It is a highly desirable large, green terrestrial elephant ear.
