flowered variety of S. angustifolia. Spheeralcea rivularis, Ton. ! ined. (Malva rivularis, 

 Dough) has been ascertained by Dr. Torrey to be the same as S. acerifolia, Nutt. 

 Malva vitifolia, Cuv. is probably another species of the genus nearly allied to the last. 

 S. incana, Ton. ined. gathered by Lieut. Abert in New Mexico, and also by Wislizenus, 

 is perhaps too nearly related to our No. 78, but more canescent with a closer and finer 

 pubescence : S. Emoryi, Ton. ined. is still another allied species, with hastate or trian- 

 gular leaves and a rougher pulverulaceous tomentum. S. pedata, Ton. ined., gathered 

 in Fremont's third expedition, has 3-5-sected leaves ; the divisions all cuneiform, 3-lobed 

 and incised. 



79. Sidalcea Neo-Mexicana (sp. nov.) : caule virgato gracili superne glabra infer- 

 ne cum petiolis foliiscpie sparsim hirtellis ; foliis radicalibus orbiculatis sinu apertis leviter 

 5-9-lobatis vel insico-crenatis, primariis basi subtruncatis, caulinis infimis profunde 7-9- 

 fidis superioribus 5-3-partitis, segmentis 3-lobatis apice dentatis, supremorum linea- 

 ribus integerrimis ; racemo multifloro ; pedicellis strictis calyce hirsuto duplo longioribus ; 

 corolla lilacina ; coccis kevissimis angulo interno mucronato-apiculatis. — Vide p. 20. 

 Moist meadows, Santa Fe ; June, July. (Also, a slender form with the lower leaves 

 more divided, at San Juan de la Vequeria, Tamaulipas, Dr. Gregg.) — Plant 12 to 18 

 inches high, at first simple, with a long, virgate raceme, soon producing axillary flowering 



§1. Pseudo-Malvastrum. Involucellum e bracteolis 1 -3 seiaceis parvis, deciduum. Carpella omnino 

 miitica. Stellato-incanre, floribus flavis croceisve. 



S. hederacea, Torr.! ined. = Malva hederacea, Bough in Hook. FL Bor.-Am. 1. p. 107. M. Cali- 

 fornica, Presl ! Rcl. Hcenk. 2. p. 121. M. plicata, Null. ! in Torr. $■ Gray, 1. c. M. obliqua, Null. ! Mss. 

 Sida obliqua, Torr. 4' Gray! I. c. — Southern Oregon, Douglas, Nullall. California, Hanke, Coulter, 

 Fremont. 



S. suxphurea, = Malva sulphurea, Gillies! in Hook. Bot. Misc. 3. p. 149, from Mendoza, is a nearly 

 related species ; and some others from the same region usually referred to Malva probably belong here. 



§ 2. Malvinda, Medik. Calyx omnino nudus, 5-angulatus, 5-fidus. Carpella pi. m. rostrata, 2 - 3-cus- 

 pidata vel aristata. Flores plerumque flavi. 



S. spinosa, Linn., et cseteris div. * & * * Torr. <$• Gray, Fl. I. c, etc. 



§ 3. Pseudo-Napjja. Calyx omnino nudus, teres, 5-dentatus. Flores umbellati-corymbosi, albi. Folia 

 palmatifida. 



S. Nap^a, Cav.= Napa?a hermaphrodita, Linn. (Vide p. 21.) 



S. Hulseana, Torr. $/■ Gray, I. c. (Abntilon Hulseanum, Torr. ined.) is probably Abutilon confertiflo- 

 rum, A. Rich. 



S. crispa, Linn, (which grows on Key West and in Texas) has 3 - 4-ovulate carpels, and is therefore an 

 Abutilon, notwithstanding its close resemblance to Bastardia, to which Adr. Jussieu referred it. 



A revision of the North American species of Sida, as thus restricted (of which there are several new or 

 undetermined species from Texas, &c), will be attempted on another occasion.
