XT) FLOItAM INDICAM (CBUCIFEE^e). 157 



The reversed hairs on the lower part of the stem, runcinate pinnatifid 

 leaves, large yellow flowers, long young pods which do not overtop the 

 raceme, and slender terete pods, 1-li" long, with a distinct straight style, 

 best distinguish this.

 titis laciniis exauriculatis, siliquis patulis gracile pedicellatis 1J-2"

I have not seen authentic specimens of this, which Boissier describes as 

 having flowers twice as large as those of S. Irio. Such is not the case in 

 our specimens ; but they are sometimes very small, and always variable in 

 size, both in this and in S. Irio : the style varies so much also in length, 

 that we should not be surprised if the two species were found to pass into 

 one.
