MALVACE^. 53 



Hooker, at Glasgow, he figured the two species, viz. N. digitata and N. 

 pedata, in the Exotic Flora. He soon identified the Malva Papaver, Cav., 

 as a third species of the genus, notwithstanding its involucre of from one to 

 three bracts, which, however, are frequently remote from the calyx or want- 

 ing; and, in the Journal of Botany, 1. p. 196, shortly afterwards added to 

 the genus another involucellate species, the Malva triangulata of Leaven- 

 worth; — at the same time suggesting that these two should be restored to 

 Malva, and two exinvolucellate species be referred to Sida. As the radicle 

 proved to be inferior in all of them, they were all referred to Malva in the 

 Flora of North America, along vi'ith a third involucrate species (the Nuttal- 

 lia involucrata, Nutt.) ; and a remarkable Rosaceous genus was dedicated 

 to Mr. Nuttall in a subsequent portion of that work. Recently, in revising 

 this group, I had occasion to point out the characters which distinguish this 

 genus from Malva, viz. the more or less beaked fruit, with an internal pro- 

 cess across the base of the beak, and the truncate petals ; and I accord- 

 ingly restored the original name of Callirrhoe ; * defining the species anew, 

 and introducing two more exinvolucellate species, namely, C. maerorhiza 

 (Sida maerorhiza, James), which had been taken as a variety of C. pedata, 

 and C. alcaeoides (the little known Sida alceeoides, Michx.), which, like 

 C. pedata, has the ripe seed so depressed by the internal process that the 

 radicle becomes ascending, although the ovule is not at all resupiuate. Since 

 the earlier sheets of the Plantce. FcndlcriancB were printed, C. digitata has 

 also flowered with us, from Texan seeds, and complete indigenous specimens 

 with ripe fruit have been examined, enabling me now to point out the true 

 difference between this species and C. pedata, and to correct some errors in 

 the synonymy, f 



* CaWiTOe, Li?ik, Handh.= ii section of AmnrylHs (Belladonna, Sweet.), and 

 is, I believe, of later date. The prior use of tiie name in Zoology will not be 

 held to forbid its restoration in Botany.

 Gray, Fl. N. Jim. l./>. 226, excl. syn. " N. digitata, Bart." — Some indigenous 

 specimens are tliree feet high ; and in cultivation it attains tlie lieiglit of four or 

 five feet, leafy to the top, and producing a long succession of iiandsome flowers 



from the axils of the leaves. The petals are deep cherry-red, witii a tiiice of 



fiurple, decidedly smaller than those of C. digitata, being less than an inch in 

 ength. The root is not thickened in any of my indigenous specimens, nor does 



it show a tendency to become so in the living plant. I suppose the j)lant 

 truly an annual or a biennial.
