From the studies I have made on balbous species in which I have found 

 elaioplasts the following may be deducted: 



(1) That the elaioplast$, besides occurring in vegetative organs, may- 

 be found in the external epidermis of all the scales of the bulb, 



(2) That the elaioplasts in bulbs, after a short existence, degenerate, 

 then disappear* 



(3) That of the two substances of which elaioplasts consist the first 

 to disappear is the oleose substance, ishile the proteinaceous substance 

 persists for varying lengths of tioe, 



(4) That in dormant bulbs the elaioplasts appear without definite 

 structure and assume varied forms which are to be considered a;s representing 

 the ultimate phases of their develojiment, 



(5) That in each renewal of functional activity of the bulb elaioplasts 

 form anew. 



The form of the elaioplasts is singularly and particularly elevated 

 in some bTilbs of Hippeastrum aulicua and of Omithogalxna caudatum . 



The principal results of my researches, then, may be thus summarized: 

 (l). I have found elaioplasts in 27 new species referable -to 19 nev/ 

 genera of Mohocotyledoneae. 



(2) I have found that there are elaioplasts even in some Dicotyledoneae 

 (where none were ever found before), namely^ in the. Malvaceae, the one faanily 

 from the many examined by me which possess them, 



(3) The elaioplasts are not to be considered as parasites (as thought 

 'Bj'' Zijnmennami) nor as organs of defense (as maintained by Eacibor&ki) , but 

 as specific organs of the cell in which they form and ssthoss function is that 

 of elaborating oleose nutritious substance.
