22<; NATURAL niSTORY OF PLANTS. 



the projections from the petals (wliieh also cover in the sexual organs 

 like a dome) are flattened in the radial direction of the flower, instead 

 of being of the same breadth in every direction as in J. miaveolctis, 

 or laterally compressed as in most species of lioUima. The genus 

 Artabotrj/.s contains about fifteen species, of which three or four come 

 from Africa,' and the rest from tropical and eastern Asia,' or the 

 Indian Archipelago.' They are shrubs, often climbers, with alternate 

 usually smooth leaves, and flowers grouped into clusters of often 

 few-flowered cymes. The chief axis of each cluster is flattened and 

 dilated into a sort of recurved fasciated hook, which bears, chiefly on 

 its convexity, groups of pedicellate flowers, whose development is 

 often partly arrested (fig. 278). 



The tree from Ceylon called Ci/afhocalyx* has a corolla like that of 

 A. uncaia, with erect blades of even more membranous texture, and 

 only touching by the edges in the bud. But the calyx is like a deep 

 cup, whose edges alone are incised into three teeth, and the flattened 

 summit of the receptacle only supports a single carpel. The uni- 

 locular ovary only supports one parietal placenta, on which are 

 inserted two rows of anatropous ovules,* and the style rapidly dilates 

 into a large flattened stigmatiferous head. The fruit is a many-seeded 

 berry. The leaves are glabrous alternate, and the flowers are solitary 

 or grouped into few-flowered cymes, terminal or leaf-opposed." 



In Jfcxalobm' (figs. 279, 2S0), the perianth is like that of a 

 (.'i/athocali/x, or any of the species o'i Artahoin/s analogous to A. imcafn ; 

 but the six petals are united into a tubular corolla in the whole oi' 

 the part enveloping the sexual organs. The membranous flat- 



came out. We mny therefore accord priority to a unicarpellary Artabotrys; and as wo have
