 ally had the more delicate varieties troubled by green fly, 

 and by mealy bug, but very little care will prevent this. 

 The chief danger seems to lie in the decaying of the roots 

 by over-watering when in growth, or by not withholding 

 water when they are in a state of rest. These remarks, of 

 course, apply only to the bulbous varieties. Sometimes we 

 have known the roots of the summer-blooming varieties to 

 be attacked by the root aphis, but this is unfrequent. The 

 foliage is of too fiery a taste to be subject to the attacks of 

 insects. 



With these few remarks we will proceed to the descrip-
