PLANTE FENDLERIAN2. 21 
Sphzralcea would appear from the character of ‘capsule disperme,” (although in fact 
only one seed commonly ripens,) and I suspect that this is the very species, although 
§- p. 681.— A well-marked genus, as founded by Clayton: but Linnzus subsequently added a second 
species (N. hermaphrodita & N. levis; the Althea ricinifolia, Herm. Lugd. p. 22. t. 23. Sida Napwa, Cav. 
1. 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 persistente, stipatus. Stigmata 
terminalia capitellata. ‘Tubus stamineus simplex, ovulum peritropo-adscendens, embryo semicircularis, atque 
radicula infera Malye. Carpella mutica vel rostrata. — Herb American ; floribus coccineis, aurantiacis, 
aureisve, axillaribus, raro racemosis. Malve et Side 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 Chrysanthe, 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.

spreading, and extremely woolly,ibut 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 / 1. c. is an involucellate Sida, of the same group as 8. hederacea.
