REMARKS

Turraea fockei can be recognized by its suborbicular leaves with domatia, solitary orange to pink flowers (rarely by two) with four petals and its tomentose calyx with bright yellow hairs ( Fig. 11B ).

Study of the original material of Turraea fockei shows that T. anomala first described in the genus Quivisia Comm. ex. Juss. by Hoffman (1881) has to be considered as a later synonym. No orginal material of the name Quivisia anomala is extant at B (Paule, pers. comm.). Therefore, the best preserved material at GOET is designated here as the lectotype.

Turraea fockei grows in the western dry deciduous forests of Madagascar. It has a quite large repartition from the tsingy of Bemaraha to the far north, east of Montagne d’Ambre ( Madagascar Catalogue 2024).
