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 CO- 

 ROLLA; but in the American Bartsiathe perianthium 

 is bloody ; in the herbaceous Cornus the petals are 

 black, but the involucrutn white; and in the Ame- 

 rican Cornus the involucrum is red, and cordate, 

 heart-shaped. In Astrantia the involucrum is colour- 

 ed ; and in Palms the spathre are bloody ; where the 

 corolla is wanting, the perianthium is wont to be 

 more coloured, especially when the flowers are blow- 

 ing, as in Ornithogalum, Pei sicaria and Polygonum ; 

 where either the Calyx or the Corolla is found to be 

 less coloured, the leaves often take a colour, as in 

 Amaranthus tricolor. 



In most plants the STAMIVA and PETALS are in- 

 serted into the receptacle, in the bottom of the flow- 

 er ; "but the plants of the class Icosandria have a mo- 

 nophyllous calyx, the inner side of which is girt with 

 a line, to which tiie stamina and petals are fastened ; 

 and the calyx is also observed to support the flowers 

 in some other plants, as in Lythrum, Epilobium, 

 Oenothera, Ammannia, Isnarda, Peplis and Elscagnus. 

 In some plants the receptacle is lined on all sides with 

 the perianthium, and the corolla adheres to the pe- 

 rianthium as though it were glued to it ; this is 

 found in the Cucurbitaceous plants, such as Cucur- 

 bita, Passitlora, Fevillaea, Momordica, Trichosanthes, 

 Cucumis, Bryonia, Sicyos, Melotliria and Gronovia; 

 the same is also observed in Cactus : In some others 

 there is a. receptacle that elevates the pericarpium, as 

 in Passiflora, Capparis, lireynia, Arum, Calla, Dra- 

 contium, Pothos, Zostera, Nepenthes, Clutia, Helic- 

 teres and Sisyrindman. 



In monopetalous flowers, the stamina are usually 

 inserted into the petal, but they are separate from it
