 Asuncion (80*1). 



Enliydra Anagallis, Gard. in Hook. Lond. Jour. Bot., viii, 409. 



Asuncion (79). November-February. 



As none of this marsh-loving family are known in this country, 

 readers of these notes may be interested to learn something about 

 them. A succulent, spreading plant, growing abundantly in miry 

 places along the borders of the Paraguay River at Asuncion, the 

 stems hollow, rooting at the nodes, and sometimes running 3-6 dm 

 Flowers inconspicuous, in sessile, axillary heads, subtended by large 

 foliaceous bracts. Involucral scales 4, large, whitish-green, often 

 closing over the flowers so as to completely hide them. Ray flowers 

 in 3 rows, white, pistillate, fertile, 3-toothed. Flowers of the disk 

 perfect, the corolla greenish-white, the stamens and style exserted ; 

 stamens black; stigma small, feathery, not appendaged. Pappus 

 none. Aehenia smooth. Receptacle chaffy, the chaff large, very 

 hair}^ and closely investing the flowers. As the native Paraguayans 

 are great herb doctors, firmly persuaded that every known plant has 

 its medicinal virtues, they prize a tea made by steeping the foliage 

 of this plant as a remedy for various disorders of the bowels.

 a sharp point above the aehenia when in fruit so as to present a 

 bristly appearance to the head.
