 than the petioles ; bracts lanceolate, cuspidate, 

 shorter than the 5 sepals; utricle wrinkled, inde- 

 hiscent, about as long as the sepals.

 obtuse or emarginate at the apex, narrowed or 

 rounded at the base, prominently veined, petioled, 

 3"-io" long, the veins often purple ; flowers few 

 together in small axillary clusters ; bracts lanceo- 

 late, subacute, shorter than the 5 oblong obtuse 

 sepals ; stamens 5 ; anthers yellow ; utricle fleshy, 

 indehiscent, faintly 5-ribbed, slightly wrinkled, 

 nearly twice as long as the sepals when mature;

2. ACNIDA L. Sp. 1027. 1753. 



Annual, erect or decumbent, glabrous branching herbs, similar to the dioecious Amar- 

 anths, with alternate petioled thin pinnately veined leaves. Flowers small, green, 1-3-bracted, 

 in terminal and axillary, continuous or interrupted spikes, or clustered in the axils. Stami- 

 nate flowers consisting of 5 scarious erect i-nerved mucronate sepals longer than the bracts, 

 and as many stamens ; filaments subulate, distinct ; anthers 2-celled. Pistillate flowers without 

 a calyx; ovary ovoid or subglobose; stigmas 2-5, papillose or plumose, short or elongated. 

 Utricle fleshy and indehiscent, or membranous and bursting irregularly or circumscissile ; 

 seed erect, smooth and shining. [Greek, without nettle.] 



About 6 species, natives of eastern North America and the West Indies. Type species : Acnida 

 cannabina L, 



Utricle fleshy, angled, indehiscent ; salt-marsh plant. i. A. cannabina. 



Utricle membranous, irregularly dehiscent or circumscissile ; plants of fresh water swamps.
