If ff Well-developed undershrubs. 



Petiole usually not winged ; racemes dense, usually clustered and shorter than the

with greenish keel ; pods puberulous, E. semialata. 



Petiole narrowly winged ; bracts and calyx appressedly brown or golden silk-hairy, the 

 latter \ in. long, the lobes subulate with the lowermost one twice as long ; corolla 



J in. long, white with rose-coloured wings, F. latifolia. 



O O Bracts scarious and stiff, very much longer than the 'flower 

 buds. Branches and branchlets more or less triquetrous. 

 Tall undershrub ; petiole narrowly winged ; lower sheathing bracts up to 2 in. long ; 

 calyx about 4 lin. long, silvery silk-hairy, the lobes linear, acuminate, the lower- 

 most one twice as long ; corolla nearly \ in. long ; pods minutely appressed 



puberulous, F. striata. 



x. x Spikes short and condensed into heads. Bracts all persistent, the 

 outer ones large and involucre-like. Pod enclosed in the calyx, 

 1 -seeded. (Lep/idocoma, Jungh.) 

 Erect undershrub ; bracts silky-pilose ; calyx \ in. long - , the lobes subulate ; corolla \ 



in. long, minutely appressed silk-hairy ; pods silky -pilose, F. capitata. 



Subg. 2 Mhynchosioides, Bak. Twining herbs or perennials. . Flowers in long 

 peduncled heads or dichotomous corymbs. Calyx-teeth almost equal. Pods 1- rarely 

 2-seeded, usually included in the calyx. Bracts minute, deciduous.
