It is very like the original species, from which it differs 

 in having smaller flowers; and especially in the umbel being 

 far less compact, with the stalks rather more than twice as 

 long as the flowers themselves. In H. kyacinthinum, on 

 the contrary, which is reported to be sky-blue, the umbel 

 is very crowded, and the stalks of the outer flowers are 

 curved downwards, and not longer than the flowers them- 

 selves. The latter may be defined thus : 



H. hyacinthinum ; floribus exterioribus decurvis pedicellorum longitudine.
