Haemanthus albiflos Facq.. ; H, ftoccineus Linn. 



In all the species of this genas which I have studied the elaioplasts 

 appear, on microscopic examination, in the adult stage, under various forms, 

 which mSiy he considered as variations of a fundamental type of globose form. 

 They frequently appear continuous, althou|;h in reality their form results 

 from, the union of many minute spheres which may be separated from one another 

 by pressure on the cover glass of the preparation. Each of these spheres 

 consists of a plasmatic stroma in which is found incltuied an oily substance. 

 With osmic acid (solution 1 per cent) the elaioplasts become almost instan- 

 taneously blg.ck (Pl. XIV, fig. h) . After treatment for a few seconds with 

 Sudan III the single spherical elements which constitute the elaioplasts 

 coalesce and from, their mass oily drops appear, while the mass and the drops 

 assume an intense red color. The oily substance resists the action of 

 acetic acid and of chloral hydrate, but dissolves easily in absolute alcohol, 

 ether, chloroform, and benzine^ It, however, resists the action of these 

 latter solvents follov/ing heating or following the action of osmic acid. 

 The elaioplasts attain greater dimensions than those of the cell nucleus. 

 They have a light yellow color and are found in the adult stage close to the 

 cell nucleus or a little distance therefrom. Their manner of development is 

 comparable to that described for Polianthes tubeCosa . 



The elaioplasts of this species are fo^md in the epidermis of all the 

 scales of the bulb, in both epidermises of the leaf, and finally in the 

 epidermis of the floral axis and of the perianth.
