central column, and tlierc arc some species of tliis genus where the 

 number of the verticils and their total number may be the same ; 

 but there are some also where three verticils may be counted, and 

 others where the androceum has only one verticil of three pieces. 

 The perianth too is imbricated and often double, and the leaves are 

 simple, penninerved, alternate or sometimes so nearly approaching 

 each other as to represent verticils. 



Cliujtia ^<A0 forms a small sub-series {Cluyticcc). AYith a parti- 

 cular habit, they have flowers (fig. 172) with 

 double imbricated perianth. The insertion of Cuytia puichciia. 

 the petals is more or less perigynous. The 

 isostemonous androceum is formed of pieces 

 borne upon a central column surmonnted by a 

 rudiment of a gyna^'ceum. A double or single 

 disk accompanies it at the base. All the known j.;„ j^.. Female flower (\). 

 species of Cluytia^ fi-utesceut or suffiiitescent, 



with alternate, simple, exstipulate leaves, inhabit South Africa or the 

 neighbourhood of the Red Sea, especially Abyssinia and Arabia. 



In the small groiip Pogonophorcœ^ Pogonophora^ consisting of 

 shrubs and trees of tropical America, has a double imbricated 

 hypogynous perianth, with five free alternipelatous stamens, and in 

 the female flower a trilocular ovary, surrounded by a membranous 

 disk. The leaves are simple and alternate. It is the same in Micro- 

 dcs/Hi's, a nearly allied genus, a native of tropical Western Africa, 

 where an isostemonous species, and of Eastern India, where a diplo- 

 steraonous species is found, furnished with five oppositipetalous 

 stamens smaller than the other five. All are inserted round a rudi- 

 ment of a central gynœeeum, surrounded by an imbricated calyx 

 and an imbricated or contorted corolla. The ovary and the fruit 

 with hard stones have two or three cells. M/'crandra is also very 

 nearly related to Pogonophora^ but the flowers are apetalons and the 

 isostemonous androceum is formed of stamens alternating with the 

 sepals whose filaments are incurved-refracted in the bud. Tt con- 

 sists of Brazilian trees with alternate leaves. Cunuria, resembling 

 Tannodia, Jairopha, and Micrandra^ has the apetalons flowers of 

 the latter, but with a diplostemonous androceum without any pecu- 

 liar curvatiou of the filaments. The disk of the female flower is 

 surmounted by six teeth (staminodes ?), and the leaves of the only 

 species known inhabiting North Brazil are alternate, thick, similar to 

 those of many Guttifers. In Mischodon, a genus presenting great
