180 MISSOURI BOTANICAL GARDEN. 



fixed, obtuse or provided with a terminal appendage, 

 dehiscing by 1 or 2 apical pores, sometimes continued 

 down the side in slits. 



In Crinodendron (2 species in Chile) and Antholoma 



i 



(2 species in New Caledonia) the corolla is urceolate 

 and the anthers open by longitudinal slits, which may open 

 more widely above or originate in a poriform opening, or 

 may be confined to the upper portion of the anther. Du- 

 bouzetia (represented by 1 or perhaps more species in New 

 Caledonia) has in some ways a very similar floral structure, 

 but the dehiscence is by a single bilabiate terminal pore. 



The Elaeocarpaceae is a highly interesting group and I 

 am far from satisfied with the treatment which can be 

 given it in this paper. 



Ochnaceae. 



All genera of the Ochnaceae are to be considered in a 

 paper on apically dehiscent anthers. The flowers show a 

 considerable diversity of form and are to be referred to 

 different types. 



Ochna (about 25-30 species distributed over tropical 

 Asia and Africa, only a few species — 3, fide Flora Capen- 

 gis — in the Cape region) has numerous stamens with long, 

 filiform filaments and oblong or linear, basifixed anthers 

 dehiscing by apical pores or longitudinal slits. It belongs 

 clearly to the Dilleniaceous type. Lophira (1 species in 

 central and west Africa) with the linear anthers dehiscing 



by short, terminal, almost poriform slits, belongs here, as 

 does also Cesj)edesia (3-4 species in Peru, New Granada 

 and Panama) with 40— GO elongate, linear, curved anthers 

 on short filaments, all turned toward the same side of the 

 flower during anthesis. 



Ulvasia and Godoya may be mentioned here as forms in 

 w r hich the stamens are more numerous than is common in 

 the Solanum-Cassia type, but for other structural reasons, 

 these, as well as the other members of this family, will be 

 considered with the members of that group.
