Reliquia Treubianae III. 
Embryosac and Embryo of Moringa oleifera Lam. 
Moringa oleifera Lam. (pterygosperma Giartner) is the best 
known representative of the tropical family of the Moringaceae. 
Indigenous to the Indies the species has been cultivated for 
many thousand years and is to be found in African and American 
tropics as well as in Asia. 
Material. 
One of the very last studies published by Trevs (Le sac 
embryonnaire et l’embryon dans les Angiospermes. Nouvelle 
série de recherches — Ann. du Jard. Bot. de Buitenzorg 1910) was 
meant as- the first of a series of articles on the subject. For 
this purpose he brought home an extensive material relating 
to embryosac formation in numerous tropical families. After- 
wards the collection passed to Prof. Went of Utrecht University 
who kindly put at my disposal the Moringa material collected 
by Trrvs at Buitenzorg (Java), which was fixed in alcohol. 
From still two other sources material was available at 
Utrecht. Botpincn collected on the isle of Curacao (Dutch West 
Indian archipelago) and Kuyrer in Surinam (Dutch Guyana). 
Fixation by both in alcohol and in Flemming’s. 
During the examination it turned out that only embryosac 
formation could be studied from the material at hand. Even in 
seeds of considerable size no trace of embryo formation was 
seen, though full-grown seeds were known to carry quite nor- 
mall embryo’s. Dr. Sranen at Paramaribo (Surinam) kindly 
helped me by sending additional stadia, collected by him and 
fixed in alcohol, which fixation proved itself to be the best.
