pletely excreted by the anthers, had coalesced into 



masses definite both in number and form, and these h 

 been taken up by appropriate processes of the pistils. Viewed 

 thus in their final station on the stigma, these bodies were 

 by some observers held to be the stamens of a gynandrous 

 flower, while the remainder of the stamineous structure was 

 left unaccounted for. By others, who combined with the 

 view of those parts that of the natural relation of the 

 parent-plant to the rest of the vegetable system, and drew 

 their conclusion in part from analogy, the same bodies 

 were surmised to be the distinct secretions of the cells of 

 the five bilocular anthers of as many stamens of a pen- 

 tandrous flower; and both their formation and station to be 

 secondary. A supposition which has been recently reduced 

 to certain knowledge, and the structure and economy of

Calotuopis consists of but one species besides the pre- 

 sent, which is a tall upright plant, sometimes acquiring 



the height of 6 or 8 feet, covered, unless at the corolla, by 

 a soft white deciduous down; leafless, except towards the 

 upper part, producing throughout a thick milk-coloured 

 juice, which presents itself on the slightest puncture. 

 Corolla purplish white, with five vertical prominent com- 

 pressed appendages, fixed at equal distances along the out- 

 side of the stamineous tube, resembling so many diminutive 

 porcelane handles, or brackets.
