In this species one finds elaioplasts in the floral axis, in the ovary, 

 in the leaves of the perigoni-um, in the lip, and the gjmostemi-um. 



They are fo'und immersed in the cytoplasm of the epidermal cells and 

 result from the aggregation of very nximerous little spheres which are strongly 

 refractile to light (PI. XV, fig, 6)» Their size upon completion of develop- 

 ment is most remarkable, since they come to occupy half, or even more, of 

 the cell cavity* Such elaioplasts are of irregular or sphericsul form and 

 roll around or cover nearly perfectly the cell nucleus (Pl, XV,. fig.. 5), 

 or they cp-n raxely be found any distance away from the cell nucleus. In the 

 most advanc?ed stage ihhey losjb their characteristic structure and become 

 granule se and vacuolated, 



Brassia brachiata Lindl% 



The elaioplasts are found in this species in the epidermis of the ovary 

 of the floral organs and are wanting in the leaves and in the adult roots. 

 They are spherical or irregular in form and where they have separated in the 

 first stage of their evolution they show in their interior some vacuoles 

 whicU increase in number, giving to the elaioplasts a granulosa appearance 

 (Pl^ XV, fig* h). 



Oncidima sphacelatum Lindl* 



The elaioplasts of X)ncidium g|feacelatum resembl-^^more nearly those of 

 the preceding species. They are found in this species in the epidermis of 

 the floral organs. In their final stage they braak up and thus multiply 

 themselves (PI. XV, fig. 3), Thus it follows that in one and the same 

 cell may b© often found more than one elaioplast. Such a method of multi- 

 plication is described also by Eaciborski in Ornithogalum comogma and in 

 0, Eckloni .
