GAPPARWACEM. 153 



the neighbouring parts of Oceania. In Calanthea? an American 



section, 2 the sepals are narrow and do not touch ; while the petals 

 are valvate in the bud. Finalty, the name Qtiadrella* has been given, 

 and generic importance assigned' to certain American species, 5 with 

 valvate sepals, often possessing an internal basilar gland, and with 

 a fruit of variable form, sometimes dehiscing at maturity ; the un- 

 armed stems bear opposite or alternate leaves. 



Under the name of Morisotiia 5 four American species 7 have been 

 distinguished. Their calyx is gamosepalous at the base, parting 

 unevenly into two, three, or four pieces on anthesis, with four 

 internal alternipetalous basilar glands. The regular tetramerous 

 corolla, the androceum of indefinite stamens, and the stipitate gynse- 

 ceum, with a variable number of parietal placentas, are those of most 

 American species of Capparis. The fruit is a corticate many- 

 seeded berry. These plants have simple coriaceous leaves, tomentose 

 or covered with scaly down, and flowers in multiiloral corymbs. 

 We make them a mere section of the genus Capparis, scarcely 

 distinct from Beautcmpsia? 



Thus limited, the genus Capparis contains some hundred and 

 twenty-five species, 9 many of them very ill-known. Their habit, 

 surface, and inflorescence are most variable. They are confined to 

 warm countries ; their northern limit is, in Europe, the north coast 

 of the Mediterranean ; Mexico in America,
