SINGULAR STRUCTURES. 33 



Andhyala ; . . .setose, bristly, as in CentaurEa ; . . .or paleaceous, 

 chaff)/, as in Hypoch;eris and Anthemis. 



In some simple flo wers the fruit has separate receptacles, as in 

 Magnolia, Uvaria, and Michelia.

OF THE SINGULARITIES IN THE STRUCTURE OF THE 

 PARTS OF FRUCTIFICATION. 



BY a singular structure of the parts of fructification is to be 

 understood such a one as is observed but in very few genera; it 

 is directly opposed to the natural structure explained in Chap. X. 

 For instances of this we may mention the Arum, whose stamina 

 are within the pistilla ;...the Adoxa, whose germen separates the 

 corolla from the calyx ;...the Salvia, whose filaments are articu- 

 late, jointed the Eriocaulon, whose stamina are placed on the 

 germen, and whose corolla and calyx are below the germen and 

 the Magnolia, the receptacle of whose fruit is capitate, headed, 

 the seeds, which are like berries, hanging by a thread out of the 

 capsule ; but to take the parts in their order. 



The Calyx is usually less coloured than the Corolla; but in 

 the American Bartsia the perianthium is red ;...in the Herbace- 

 ous Cornus the petals are black, but the involucrum white ;...and 

 in the American Cornus the involucrum is red, and cordate, that 

 is, heart-shaped. In Astrantia the involucrum is coloured ; and 

 in Palms the spathse are red ; where the corolla is wanting, the 

 perianthium is apt to be more coloured, especially when the flow- 

 ers are blowing, as in Ornithogalum, Persicaria, and Polygo- 

 num ;.., where either the calyx or the corolla is found to be less
