 thrive luxuriantly, and blossom about tbe beginning of the 

 hot season in February and March.

 round, villous branches spreading in every direction ; height 

 of the luxuriant plants in the Botanic garden, not more than 

 two feet, but covering an extent of ground fully twice that in 

 diameter. Leaves stem-clasping, runcinate, spinous-toothed, 

 villous above, and tomentose, or cottony underneath. Heads 

 of flowers terminal, solitary, globular, white. Common pe- 

 rianth of several, totally reflexed, spatulate, laciniate, ciliate, 

 permanent scales. Proper perianth double, one-flowered ; 

 the exterior one of several, acute, imbricated scales, surround- 

 ed with much longhair, here and there one of the scales end- 

 ing in a long, straight, simple spine, which projects a little 

 beyond the flowers ; the inner or proper perianth, one-leaved. 

 Tube gihhoiis. J?orrfer five-parted ; division unequal, and 

 ciliate. Florets, tube cylindric ; divisions of the border re-

* I may say triple, if the large quantity of long white hair which 

 surrounds the many-leaved; imbricated one, can be so called.
