for which we are indebted to the kindness of His Grace the

except B. laxa, and in that plant there is a solitary tubular 
floret in the disk ; but here the stamens are not monadel- 
phous, nor is there a solitary tubular flower in the disk ; in 
the place of the latter there is a space which pours forth
