 the tips of the valves spreading : seeds 0. 7 mm. broad, gray -black. 



In fields and waste places, Maine to Ontario, British Columbia, Florida, Texas and Mexico. Sum- 

 mer. A very slender state with globose calyx-tubes, occurring in Georgia and Florida, is known as S. 

 antirrhina lindria Wood. SLEEPY CATCHFLY. 



5. Silene stella ta (L.) Ait. f. Perennial by a stout rootstock, slender, pubescent

 long as the tube, somewhat spreading : petals white, spatuiate, about 2 cm. long, laciniate, 

 the segments often toothed at the tips : filaments nearly as long as the petals : capsules sub- 

 globose or ovoid-globose, smooth, shining, 6-7 mm. in diameter : seeds black, a little more 

 than 1 mm. in diameter. 



In woods, Massachusetts to Minnesota, Georgia and Texas. Summer. STARRY CAMPION.

 reclining, 3-8 dm. long, simple or branched : leaves opposite ; blades lanceolate or linear- 

 lanceolate, sometimes slightly broadest above the middle, 4-15 cm. long, acuminate, some- 

 times ciliate, sessile : flowers about 2 cm. long : calyx viscid-pubescent, 1.5-1.8 cm. long ;
