Walafrida. | SELAGINE# (Rolfe). 117 
Genera Plantarum it was reduced to Selago, because the calyx is identical with 
that of Selago, sect. Macria, E. Meyer, The character of the calyx, however, in 
this Order has been so much relied upon for generic limitations that I have here 
restored Walafrida, enlarging it by the addition of the species of Selago having a 
three-lobed calyx (sometimes 2-lobed by abortion), thus restricting Selago to the 
species having a 5-lobed calyx. The extra South African species are W. lacunosa, 
Rolfe (Selago lacunosa, Klotzsch), W. alopecuroides, Rolfe (S. alopecwroides, 
Rolfe), W. angolensis, Rolfe (S. angolensis, Rolfe), and W. Dinteri, Rolfe (S. 
- Dinteri, Rolfe), all from Tropical Africa, and W. muralis, Rolfe (8. muralis 
Benth. & Hook. f.), from Madagascar. ;
