^86 NATURAL HISTORY OF PLANTS. 



they are also often solitary at the ends of the branches or in the axil 

 of the leaves ; they are American species. 



Amaracarpus ^ has all its flowers axillary, solitary or few, tetramerous 

 and with bilocular ovary ; in other respects they are the flowers of 

 Psychotria more or less enveloped by stipuliform bracts forming an 

 involucre. They are shrubs of Java. There is one in the Marian 

 Isles whose flowers, axillary, are rather numerous in each glomerule. 



Pyramidura^ comprises New Caledonian Uragogas whose fruit is 

 angular, with salient vertical ridges like narrow wings. In Stauragoga,^ 

 a Marian species, these wings are much more developed, but there 

 are only two to each carpel, so that the transverse section of the 

 fruit, as in most Mulinece, has the form of a St. Andrew's cross. 



Forcij)ella^ consists of New Caledonian Uragogas whose carpels, 

 furnished with ridges, are united by a sort of columella with two 

 branches, corresponding to the interval between the margins, them- 

 selves forked in two divisions. 



In Apodagoga,^ from the same country, the fruit has salient ridges, 

 but, like the flowers, they are nearly sessile, and the flowers them- 

 selves, united in cymes at the ends of the branches, have a long 

 corolla with thick and narrow lobes, and are surrounded by oval or 

 cordate decussate leaves forming an involucre. 



The inflorescences are reduced to two or three or even to a single 

 flower in Oligagoga, small shrubby species of New Caledonia ; but 

 these inflorescences are terminal, whilst in Tolisanthes,^ from the same 

 country, having the same foliage as Amaracarpus, the flowers are 

 axillary, solitary, and pedunculate. Hereby this type connects the 

 many-flowered Uragogas with terminal inflorescences to LitosantheSy'' 

 a Javan shrub with small leaves which has the tetramerous flowers of 

 Uragoga, solitary or geminate on a small common axillary axis and 

 four uniovulate cells in the ovary. Margaritopsis,^ a Cuban shrub, 

 also with small leaves, has the flowers of Uragoga, axillary and
