 N. Y. 2. p. 172. Malva involucrata, Torr. Sr Gray, Fl. 1. p. 226. — Plains, from the Platte to Texas and 

 west to the Rocky Mountains. — I have for several years had this handsome species in cultivation in the 

 Cambridge Botanic Garden, from seeds taken from specimens gathered by Col. Fremont. It forms a very 

 large root, which stands the winter well in the open air. The showy flowers are cherry-red with a tinge of 

 purple, deeper colored and one third smaller than in C. Papaver, and are produced from spring until late in 

 autumn. On prolonged flowering stems the upper leaves are abortive, and a membranaceous bract, formed 

 of the two united stipules, subtends the peduncle.
