Section II.— FIBRO-MEMBRANACEI. Continued. 



Autumnal, with a corm tunic of membranous tissue or of membranous 

 tissue interspersed with nearly parallel fibres. 



Flowers lilac or white. 

 The five flowering autumnal species — 



46. C. caspius, 



47. C. Tournefortii, 

 47^. C. Boryi, 



48. C. veneris, 



49. C. laevigatus, 



form a natural group to which no other species are nearly allied. All have white anthers and capillary 

 st.gmata. The first four have thin nbro-membranous corm tunics; and the last, C. lasvigatw, being 

 read, y distinguished from the others by its hard coriaceous tunic. All of the five species are remarkable 

 tor the small number of roots produced from the base of the corm.
