land (of which it is doubtful if the petals are ever sulpliur-color), and 

 the H. grandljlorus of Michaux. Cavanilles described and figured his 

 species from a specimen in the herbarium of Jussieu, with upper leaves 

 only. Var. occidentalis, the H. Moscheutos ? var. occidentalis, Torr. 

 in Wilkes Expedition, and H. Californicus of Kellogg, which grows 

 on the Sacramento and San Joaquin in California, appears to be a 

 form with less hirsute but yet densely jDubescent capsules. An inter- 

 mediate form was collected by Thurber near Janos, in Chihuahua. 



H. Moscheutos, L. We take it as fairly made out that H. roseus 

 is the American species, somehow introduced into the South of Europe. 



H. MiLiTARis, Cav. To this apparently belongs H. Carolinianus, 

 Muhl., and probably of Elliot. 



H, Trionum, L. To this old-world species of the gardens belongs 

 H. Collmsiana, Nutt., as to Nuttall's plant collected by Ware, if a 

 specimen from herb. Collins may be trusted. But in the Torreyan 

 herbarium that species is represented by a leaf or two of H. 3Ianihot, 

 and a leaf with two flowers of //. esculentus. 



H. (Paritium) tiliaceus, L., and Thespesia populnea, Correa, 

 have reached the Keys of Florida, both probably rather denizens than 

 natives.
