■j- The generic character of SAXGirisonBA varies considerably as stateil 

 by different aiuhors ; by Jits si eu it is " Calyx 4-fidus, basi 2-squamo- 

 sus. Petala 0. Stamina 4. Germina 2; styii 2; stigmata 2 simplicia. 

 Semina 2 intr^ calycem capsularem ;" — by Hooker, " Perianth. 4-lobed, 

 superior, coloured, having 4 scales or bracts at the base. 1-ruit 1— 2-seed. 

 ed, surrounded by the persistent base only of the perianth." Fl. Scot, p- 

 48. In the Gen. pi. of Schrebcr the stvle is describe'^l R8 filiform an-'^
