the style is also m\icli more elongated. lu others, the lines of de- 

 hiscence in the anthers are short enough to have been described as 

 pores. ^ In the species of which the type of the genus Conosainum has 

 been made,- the fi-ee part of the stamens is very 

 short and has for a common support a conical pro- 

 longation of the receptacle. In Adoiojwltis ^ (fig. 

 212, 213), Gymnostillmfjia^ GijmnantJies,^ Dactij- 

 lostemon,^ etc., of which distinct genera have also 

 been made, the sepals of the calyx in the male 

 and female flowers may be reduced to very small 

 tlimensions, being represented by very tiny cut j,;„ 

 leaves (fig. 213, 214), or even disappearing 

 altogether. The receptacle supporting them has simply the 

 form of a surbased cone, or as in StilUnc/ia,'' GymnostiUhuiia, and 

 Adenopeltis^ it is dilated into a triangular platform, the horns cor- 

 responding to the shells of the fruit it supports. In this case 

 the cells are sepai'ated below by a short columella, while in 

 Maprounea this remains rudimentary.^ As to Bactijlostcmon^ not 

 only are they remarkable for the little development of the calyx, 

 but also the number of stamens in each flower may be as many as 



2U. M;tle flowers (1).
