Two new species of Aloe in Kenya

Summary: Aloe springatei-neumannii, from southwestern Kenya, has soft maculate leaves and flowers with an abrupt constriction above the ovary, which are characters that are typical of the Series Saponariae. It is close to A. wollastonii, but is distinguished mainly by the fewer inflorescence branches, and the yellow flowers with floral bracts much shorter than the pedicels. Aloe tegetiformis, from a mountain in northern Kenya, has profusely branching prostrate stems and grows into a dense mat overlying rocks or soil. It is related to A. morijensis, which is typically a tall scrambling plant with larger leaves and larger inflorescences.

Aloe rendilliorum: a new species in northern Kenya

Summary: Aloe rendilliorum is a small shrubby species with unspotted rough-textured leaves and a sparsely branching panicle of pink flowers. It is closely related to A. archeri and A. tugenensis, but is a smaller plant and occurs further north, in the territory of the Rendille people.
