Mr. Woods on the Species q/Tedia. 431 



d. Barren cells 2, hardly touching in the middle, prolonged into teeth 



or horns, but not forming a membranous calyx. 



10. F. echinata. Cells quite separate, each terminating in a recurved horn. 



Flower.s in sessile heads on the thickened stalks. 

 Common on coasts of the Mediterranean. 



11. F. frigonocarpa. "Fruit triangular, hardly crowned. Angles callous. 



Flowers in heads. Leaves quite entire, the upper ones oblong-ciliate at 

 the base. 

 " Constantinople." 



12. F. sphcerocarpa. " Fruit globose, with 3 very short teeth, of which one is 



longer, one face umbilicate, the other two-ribbed. Bractese lanceolate." 

 I follow De CandoUe in keeping this separate, although, if it truly belong 

 to this division, I see nothing by which to distinguish it from F.pumila. 

 Sicily. 



13. F. pumila. Fruit terminating in three very short teeth. Flowers in loose 



heads. Bractese scariose, ovate. 

 South of France. 



e. Barren cells 2 contiguous. Crown erect. 



14. F. Auricula. Crown of one membranous leaf. Flowers distant. Upper 

 leaves inciso-dentate at the base. 



France, &c. 



a. Crown simple. 



/3. Tridentate. Crown toothed. 



f. Barren cells 4. 



15. F. vesicaria. Calyx inflated, with minute inflexed teeth. Flowers in glo- 

 bular heads. Bractese orbicular. Upper leaves pinnatifid at the base. 



South-east of Europe. 



g. Barren cells wanting, or reduced to a mere nerve. Panicle nearly 



fastigiate, the lower flowers solitary. 



16. F. lasiocephala. "Crown with 6 subulate, hooked, smooth teeth, longer than 



the hirsute border." Reichenbach quotes Betcke for this plant, and says of 

 it " that the barren cells are so far obliterated that the section is like that of 

 F. eriocarpa." In other respects it appears closely to resemble F. hamata.
