THE DIFFERENT KINDS OF CALYX. 



The term Calyx, like our words, horse, bird, dog, habitation, is a generic word, including 

 several distinct kinds, thus : 



I. Perianth (Perianthium), is the outer expanded covering of a flower,.. .the most common 



kind of Calyx,... usually green,... sometimes coloured,... contiguous to the corolla,... pro- 

 tecting the organs for reproduction in their infant-state,... sometimes caducous,... often 

 abiding with the fruit,... and sometimes even serving the office of pericarp,... usually single, 

 ...occasionally double,... not unfrequently very obscure,... or wholly deficient. 



II. Involucre (Involucrum), is a calyx remote from the flower,.. .most commonly stationed 

 at the foot of a general, or partial, umbel. 



III. Spathe (Spatka), a species of calyx, which first involves the infant-flowers like a sheath, 

 and then opens longitudinally. 



IV. Glume (Ghana), the outer valves, or husk of corn, or grass, enclosing one, or more, 



florets. 



V. Ament (Amentum), small chaffy scales, protecting the florets placed on a thread-like 

 common receptacle. 



VI. Calyptra (Ca/yptra), the covering of a moss, placed over it, like a cap or bonnet. 



VII. Volve (Volva), a membrane, which involves the fungus in its infant-state, and which 

 afterwards appears in a lacerated form on the foot-stalk.
