NATURAL HISTORY OF PLANTS. 



Cadaba* in perianth comes pretty near certain species of Capparh; 

 for of the four unequal caducous sepals, two are external and 

 valvate, enveloping the others. There are either four petals, or only 

 two, according to the species. There are from four to eight 

 stamens, below which the receptacle is often prolonged into a 

 large tubular or solid prominence, sometimes ending in a sort of 

 galeate dilatation. The stipitate ovary contains two or four multi- 

 ovulate placentas. The fruit is a cylindrical berry, dehiscent or 

 indehiscent. A dozen species of Cadaba are known, unarmed or 

 spiny shrubs from Tropical Africa, and Asia, and the Cape, with 

 simple or trifoliolate leaves, and axillary flowers, solitary or collected 

 into racemes or corymbs.' 2 



Euadenia? closely allied to Cadaba, links it with Cratceva. The 

 calyx and corolla are tetramerous ; but the posterior pair of petals 

 are much more developed than the other pair. There are five 

 stamens, and a stipitate gymeceum like that of Cadaba; but the 

 gynophore bears posteriorly, between the two large petals, a very 

 long appendage ending in five lobes or bearing five distinct glands. 

 The fruit is a globular or elongated berry. The two known species 

 of this genus are glabrous shrubs from the west of Tropical 

 Africa. 4 Their leaves are trifoliolate, and their flowers form terminal 

 racemes. 



In Cratceva* also the calyx has four imbricate sepals, and the 

 corolla four equal or unequal petals with long claws, and the poste- 

 rior may be larger than the anterior. The stamens vary from eight 

 to twenty in number ; near their insertion the receptacle is more or
