distinguish the calyx from the corolla. There 

 is only one style, with three stigmas, which are 

 always more or less leafy, and the anthers (which 

 are never more than three) are always turned 

 away from the pistil. In Ferraria, the filaments 

 of the stamens grow together, and form a hollow 

 tube, as in the Passion-flower, surrounding the 

 style and stigmas ; and in the Saffron Crocus 

 (C.sativa), the stigmas (which, when dried, form 

 the saffron) are so heavy, as to hang out on one 

 side of the perianth from between the segments. 

 Most of the genera have solid bulbs or corms at 

 the base of their stems ; but some, such as 

 Marica, Sisyrinchium, and Patersonia, have only 

 fibrous roots. The genera Colchicum and Bul- 

 bocodium very much resemble the Crocus in the 

 appearance of their flowers ; but they are dis- 

 tinguished by having three styles and a superior 

 ovary, and they are included in the order Melan- 

 thacese. 



ORDER CLXXXVIII.— HtEMODORACEtE. 



The principal genera are Wachendorfia, 

 Hsemadorum, and Anigozanthos, wdiich differ 

 from the preceding genus principally in having 

 six stamens, the anthers of which are turned 

 towards the stigma. Most of the genera have 

 only fibrous roots, but Wachendorfia has a 

 rhizoma, producing buds in the scales. The
