 simple at the lip. Sti/iules amplexicaul, lacerate, scarious. 

 Peduncles axillary towards the summit of the stem, viscid- 

 pubescent. Calyx pubescent ; leaflets ovate-oblong, obtuse. 

 Petals dark rose-colour, ovate, as long as the calyx. Stamens 

 3 — 10, Ca/isule about one-third longer than the calyx. Seeds

PIae. In salt marshes. Common in the vicinity of New- York, 

 and probably along the whole coast of North- America. Br. 

 Jiarrat i has found it as far up the Hudson as Haverstravf 

 Bay. May — November. 



The common variety of our salt marshes appears to be 

 nothing more than A. rubra, altered by its maritime situation. 

 I never could distinguish the remarkable difference in the 

 seed, mentioned by Smith, and therefore suspect the A. 

 riaritwia of tiiis discriminating Botanist to be distinct frora.ou?
