>phaera]cea would appear from the character of " capsule dispermae," (although in fact 

 only one seed commonly ripens,) and I suspect that this is the very species, although 



Sj- p. 681. — A well-marked genus, as founded by Clayton : but Linnaeus subsequently added a second 

 species (N. hermaphrodita & N. laevis ; the Althaea ricinifolia, Herm. Lugd. p. 22. t. 23. Sida Napaea, Cat-. 

 I. c), which is a true Sida in all its technical characters. The latter, Hermann states to have been raised 

 from seeds brought from Virginia ; but as it has long been widely diffused in cultivation, while it has nowhere 

 been found wild in the United States, I suspect that it is not of North American origin. 



' 5. MALVASTRUM, Nov. Gen. 



Calyx nudus, seu bracteolis 1-3 setaceis caducis, raro involucello triphyllo persislente, slipatus. Stigmata 

 terminalia capitellata. Tubus stamineus simplex, ovulum peritropo-adscendens, embryo semicircularis, alque 

 radicula infera Malvae. Carpella mutica vel rostrata. — Herbae Americana? ; floribus coccineis, aurantiacis, 

 aureisve, axillaribus, raro racemosis. Malvae et Sidas sp., Auct. 



The propriety will scarcely be doubted of associating in a separate genus such closely related species as 

 those of the first section, which have been arbitrarily and variably referred, sometimes to Malva and sometimes 

 to Sida, but which are capable of being clearly and precisely distinguished from either. If the yellow-flower- 

 ed species with a somewhat different habit and usually a manifest persistent involucre, which form the second 

 section (the Chrysanthae, DC, &c), are correctly referred to this genus, it will comprise a large number of 

 species from tropical and South America, which need an elaborate revision. I enumerate below merely the 

 North American species which are known to me. 



§ 1. Flores miniati. Involucellum nullum, vel parvum, e bracteolis 1-2, rarius 3, setaceis plerumque 

 caducis. Carpella mutica. — Herbae stellato-incanae, perennes.

4. M. Frejioxtii ( Torr. ined.) : lana alba dense implexa undique tomentissimum ; foliis rotundatis basi 

 truncatis crenatis subtrilobis breviter petiolatis ; floribus in axillis glomeratis subsessilibus, bracteolis involucelli 

 3 setaceis calyce lanatissimo brevioribus. — Interior of California, Fremont. The plant is apparently low and 

 spreading, and extremely woolly,J)ut the wool seems to be more or less deciduous from the adult leaves, 

 which are nearly two inches broad. The unopened flower-buds resemble pellets of wool. The expanded 

 corolla is an inch in diameter. Fruit unknown. 



Along the Andes are numerous species, among which is Malva humilis, Gillies .' in Hook. Bot. Misc. 3. 

 p. 150 ; but the M. sulphurea, Gillies ! I. c. is an involucellate Sida, of the same group as S. hederacea.
