tnim; but I believe that that genus should be merged in Sphaeral- 

 cea. Malvastrnm coccineum, the type of the genus, has the habit 

 of the typical species of Sphaeralcea. The fruit is also the same 

 except that the empty non-reticulate portion of the carpel is 

 much reduced. M. grossidariaefolium and M. Afunroaniim with 

 little more developed upper portions have been tossed back and 

 forth between the genera Malvastrnm and Sphaeralcea. Six species 

 should be transferred from Malvastrnm to Sphaeralcea under the 

 following names.
