Amphicarpcea monoica. 



A very short account appears in "The Power of Move- 

 ment in Plants." 



In i S 7 S , Kaiiow 1 '' reported investigations upon Synchil- 

 rt'um fulgens — var. decipiens — which badly infests the 



plant in some localities. 

 During 1886 and 1887, Meehan" studied the flowers and 



fruit The account of his investigation is found in the 

 "Proceedings of the Academy of Natural Sciences (Phila- 

 delphia, 1887)." The results of his observations are sum- 

 marized at the close of his paper. The statement given 

 below is not an exact quotation ; the arrangement of 

 facts, however, is that used by him. His conclusions are 

 as follows : 



1. Climbing as well as trailing stems bear apetalous 

 flowers. 



2. These produce a third form of legume. 



3. Petaliferous flowers under suitable conditions of nu- 

 trition produce legumes as freely as leguminous plants gen- 

 erally. 



4. Petaliferous flowers are adapted to close fertilization ; 

 the apetalous are fertilized from these. 



In 1890, Huth 17 published a paper, entitled, " Uber geo- 

 karpe, amphicarpe, und heterokarpe Pflanzen." He classes 

 Amphdcarpcea under the second heading indicated in the 

 above. 



Macfarlane 19 reported to the Botanical Section of the 

 Academy of Natural Sciences (Philadelphia), his observa- 

 tions upon the production of cotyledonary buds. About 

 the same time (1893), in a lecture delivered at the Woods 

 Holl Marine Biological Laboratory, 20 the sensitivity of 

 AwpJiicarpiEa was compared with that of Mimosa, Cassia, 

 Oxalis, etc. 



This list comprises the known contributions to Botanical 

 Literature concerning AmpJiicarpata up to the present time.
