Malvastrum Purdiaei, A. Gray, described in Bot. U.S. Expl. Exp. p. 150, 
in adnot, is a distinct plant from the Malva Purdiaei, Planch., described 
in Triana et Planchon, Prod. Fl. Nov. Granat. p. 154, although they are 
there regarded as synonymous. According to Gray the peduneles are 
terminated by a capitate cluster of three flowers, * pedunculis...... apice 
capitato-trifloris.” The calyx is hairy externally and the carpels are 
muticous and tomentose. Malva Purdiaei, Planch., described from the 
specimens in Hooker: herbarium, on the other hand, has the peduncles 
uniformly one-flowered, the calyx is glabrous except in rare cases, and the 
carpels are beaked. This latter plant must therefore be described as a 
new species, and the name Malvastrum purpureum, A. W. Hill, has been 
assigned to it (v. p. 219). 
Further confusion has been introduced into the synonymy of this Species 
owing to the fact that Triana and Planchon have deseribed it as Malva acaulis,
