On the cover: Aloe ribauensis McCoy, Rulkens & Baptista sp. nov., with simple and branched inflorescences, exhibit the characteristic apical tuft of sterile bracts. The reason for this character is currently unclear, but in discussions with Tom McCoy, who has wide experience with birds, the possibility that it is a perch has arisen. The bulb Babiana ringens, which is pollinated by sunbirds (Nectarina spp.), produces a long stretch of similarly sterile, terminal flower stem. This seemingly useless appendage functions solely as a perch, to facilitate pollinator access.
