CAPPABIDAQE&. 157 



less hypertrophied between the petals into distinct glandular lobes 

 or a cupuliforra disk ; but we do not find the enormous backward 

 process of Euadenia and certain Cadabas. The long-stipitate ovary 

 has two placentas ; and the globular or ovoidal berry internally 

 resembles a Caper. Cratceva consists of glabrous trees or shrubs, 

 with trifoliolate leaves, and handsome flowers, often polygamous, 

 and collected into axillary and terminal racemes. Some half-dozen 

 species are known. 1 



Boscia 2 has little tetramerous apetalous flowers. The sepals, 

 usually caducous, are valvate or scarcely imbricate in the bud. At 

 the foot of the stipitate gynasceum is found a little glandular disk, 

 at the level of which are inserted from six to twenty stamens. 

 The ovary, surmounted by a little depressed sessile stigma, has two 

 parietal pauciovulate placentas. The fruit is generally globular, 

 with one or few seeds in the incomplete cells. The embryo is fleshy 

 and scented, rolled up, with traces of albumen between the folds. 

 Boscia consists of unarmed glabrous shrubs from Tropical Africa/ 

 Their leaves are simple, articulate, with two small lateral stipules ; 

 their flowers are in small racemes or corymbs. 



In Bitc/tiea, 4 a neighbour of Boscia, the flowers are regular and 

 tetramerous with a valvate calyx, but they are large, with a small 

 expansion of the receptacle above the perianth, and four 5 long 

 unguiculate petals forming wavy ribbons, and valvate-induplicate in 

 the bud. On the convex top of the above-mentioned receptacular 

 dilatation are inserted the indefinite stamens, from the middle of 

 which rises the long slender foot of the ovary. The ovary, sur- 

 mounted by a large sessile stigma, contains three or four multi- 

 ovulate placentas. The fruit is an oblong stipitate berry, like that 

 of certain Capers. The three or four known species 6 of this genus
