Notes on Aeginetia Indica, Linn. 



{Resume). 



By 



S. Kusanc. 



With Plate I. 



1. Aeginetia indica, L., belonging to the Orobanchaceae, is widely 

 distributed in Japan. The short stem with a few scaly leaves produces one 

 to numerous long flower-stalks, each carrying a single terminal flower.^ In 

 the vicinity of Tokyo, it continues to bear flowers during about four months, 

 beginning with July. 



2. It is found parasitic generally upon wild grasses, e. g., Mlscanthus 

 sinensis, (Anders.) and Garex lanceolata, Boott. An injury is also done 

 on some cultivated plants, such as Zingiber Mioga, Rose, mountain rice 

 (Oryza sativa, L.), Setaria italica, Kth. var. germanica, Trin., Zea Mays, 

 L., Panicwn miliaceum, L. and P. frumentaceus, L.^ Since nearly 

 ten years, the cultivation of sugar-canes (Saccharum offlcinarum, L.) in 

 Bonin Islands has undergone the greatest damage from the attack of this 

 parasite. The subjoined photograph drawn from a specimen brought from 

 there and now preserved in the Botanical Laboratory, Agricultural College,. 

 Komaba, would amply express the luxuriant growth of the parasite. 



3. As regards the germination of its seeds and the development of its 

 seedlings, Aeginetia agrees with Orohanche.^ If ripe seeds, as soon as 

 collected, are sown on the root of the proper host (e.- g., MiscantJms 

 sinensis), they will germinate in the next spring and then come to bear 

 fl.owers in the same year.
