Macrifoliae (the climbing-aloes) is a genus of succulent plants in the subfamily Asphodeloideae, comprising seven species found in Southern Africa.

They are typically multi-branched climbing or sprawling shrubs, with long spindly stems and a large woody base on the ground.

These characteristics, as well as their soft, narrow, triangular leaves whose lower part ensheathes the stem, make them easy to distinguish.

Further west, the Fynbos vegetation of the neighbouring Western Cape is subject to frequent fires, making it relatively inhospitable for Aloes.

In contrast, the species from drier regions with low, sparse, fynbos vegetation tend to be more "decumbent", rambling along the ground - with no need for their leaves to be recurved.

[5] Due to their hardiness and the wide range of flower colours, these slender succulents have become popular ornamental plants in South African gardens.
