Monochcetum alpestre. 



'posed of cymes or glomerules, is terminal or more rarely axillary 

 or inserted in the side of the branches. 



Some Miconias, of which a genus Tetrazygia has been made, have 

 the calyx campanulate or nearly so, truncate or indented with five 

 teeth at the margin, and an ovary altogether inferior and, it is said, 

 adherent; the flowers are 

 generally rather large. They 

 form only a section of this 

 genus. In others, called La- 

 ceraria, the calyx opens irre- 

 gularly at the time of anthesis. 

 By these and some other types, 

 Miconia is inseparable from 

 Pachyanthus, whose flowers in 

 cymes, generally not nume- 

 rous, have a superior calyx 

 with five or six divisions fur- 

 nished externally with an ap- 

 pendage or triangular promi- 

 nence. Calycogonium will also, 

 with us, form a section of the 

 genus Miconia. The lobes of 

 the calyx are ordinarily fur- 

 nished externally with appen- 

 dages of various form, pointed 

 or tubercular, sometimes nil, 



and the ovary, depressed at the summit, is inferior. It inhabits the 

 Antilles. Conostegia is Miconia with compound terminal clusters, 

 often much developed, the flowers having a simple calyx like that of 

 Laceraria ; but it detaches itself circularly at its base, forming a 

 conical hood. Pterocladon Sprucei, a species from eastern Peru, is a 

 Miconia with numerous flowers having the external surface of the 

 floral receptacle furnished with five vertical salient layers and the 

 pedicel in the interval between the sepals. The ovary, half adherent, 

 is surmounted by a style with peltate stigmatiferous head, and the 

 throat of the receptacle is salient and more or less crenelate. 



In the Brazilian Leandra, the flowers are those of a Miconia with 

 the gynsecium nearly free ; bat they have pointed petals and bracts
