but it has larger flowers and wider leaves than either; its 

 appearance and its comparative rarity suggests that it may be 

 a natural hybrid between G. emarginata and G. gracilis rather 

 than an intermediate condition of a somewhat variable species in 

 which all three forms are to be included. This also is a point that 

 must be left for settlement by field botanists at the Cape. 



It may be noted that while, in herbarium specimens, the true 

 G. linoides dries pale green, both G. gracilis and G. emarginata 

 dry brown. 



It has to be added that there is in the Delessert Herbarium 

 a specimen of G. gracilis collected by Verreaux and said to be 

 from Uitenhage; also that in the Vienna Herbarium there is 

 another, collected by Poeppig, said to be from Port Natal. These 

 two localities must, however, for the moment be considered as 

 requiring verification.

The typical form of this very distinct species has much the 

 facies of Orphium frutescens, with which in some collections it 

 has been placed. The narrow-leaved form has, on the other hand, 

 been issued by E. Meyer along with G. linoides, to which species

the corolla tube, and still 'more markedly "as regards calyx. 

 This species is unlike most of the other species of the genus in 

 drying black.
