Südafrikanische Steppenprovinz: Natal, Inchanga (Engler n. 2712!). 



Nota. Stirps valde insignis est et quasi medium tenet inter G. pulchellam et G. KrooJcii. 

 Ramuli dense foliosi et satis microphyllini more specierum e sectione Daphnoidearum, quarum 

 indumentum G. hybrida habet; fundus calycis <5 autem glandulis paucioribus onustus est 

 numerus glandularum mox tantum 4 0, mox db 20. Folia latiuscula et graciliter petiolata 

 G. pidchellam in mentem revocant. Cum G. natalensi, quacum cl. Engler plantam conjunxit, 

 nulla adest affinitas.
