ties. The lateral angles of the leaf are produced so little that the 

 outer margin is left nearly straight if the middle lobe is cut oif. (See 

 fig. 1 and compare with fig. 2.) The pulvinus at the base of the 

 leaf blade is red, as well as the adjacent part of the petiole, and es- 

 pecially the somewhat swollen upper side of the end of the petiole, 

 which may be looked upon as a part of the pulvinus. The involucral 

 bracts are nearly orbicular, very deeply cordate at base and mar-

 quality. The seeds are longer and more angular than in the Egyp- 

 tian cotton, and the surface is usually completely naked after the 

 lint is removed. In rare cases there may be fuzz at the ends of the 

 seeds, as in the Egyptian cotton, or even a larger amount.
