16 PLANTS T7R1GHTIAN^. V. 



now can hardly doubt that the drawing sent to Sir Wm. Hooker, from which the 

 figure in the Exotic Flora was made, represents the same plant. Nuttallia jyedata 

 therefore merging in the earlier Callirrhoe digitata ("of which it is merely a state, 

 not a distinct variety), my name of Callirrhoe pedata may be allowed to stand for the 

 present plant, excluding the Nuttallian synonymy, rather than that a new specific 

 name should be introduced. 



39. SiDALCEA malvteflora. Sida malvaeflora, Mog. 8c Sesse, Fl. Ic. Mex. ined. ; 

 DC. Prodr. 1. p. 194. Sidalcea Neo-Mexicana, Grai/, PL Fendl. p. 23. Margins 

 of the Limpia River ; Aug. " Plant 2-8 feet high : flowers purple." — That this is 

 the original Sida malvseflora, I am convinced by inspection of the drawing in the 

 collection of Prof De Candolle, and of a specimen in Pavon's herbarium (now be- 

 longing to M. Boissier), ticketed " Sida palmata, Nueva Espagna." The drawing 

 represents the stems, petioles, &c., as beset with spreading bristly hairs. The spe- 

 cimen above mentioned is much less so, and the plant is said in the Prodromus to be 

 " glabriuscula." I am now of opinion, that the Sidalcea Oregana, which is the plant 

 in cultivation under the name of Sida malvseflora, is not specifically distinct ; and 

 that here also belongs the Sida delphinifolia, Niitt., which, from an original spe- 

 cimen in the Hookerian herbarium, I find has a perennial root. It is therefore dis- 

 tinct from the plant of Hartweg's Californian collection. No. 1667, which is charac- 

 terized in PI. Fendl. I. c, and in Plantce Hartivegiance, as Sidalcea delphinifolia, and 

 its stamineal column and fruit figured in the Genera Illustrata, 2. t. 120. The lat- 

 ter may be named S. hirsuta.* 



40. Malvastrum tricuspidatum. M. carpinifolium. Gray, PI. Fendl. p. 22 

 (excl. syn. Sida carpinifolia & S. planicaulis), Sj" PL Lindh. 2. p. 161. Malva tricus- 

 pidata, Ait. Keio. ed. 2, 4. p. 210. M. Lindheimeriana, Scheele in Linncea, 21. p. 

 470. W. Texas, &c. — Sida carpinifolia, Linn. f. 8uppl. p. 307, is a true Sida, and 

 is well distinguished in the original description by its short petioles, bifarious leaves, 

 sufi'ruticose stem, and biaristate carpels. It was merely a cultivated plant in Madei- 

 ra. (" Hah. in Madera in horto monasterio Sti Francisci, F. Masson.") Having no 

 specimen of it (and indeed I have as yet seen none from the Canaries), but having, 

 under that name, a Madeira specimen of the Malva tricuspidata. Ait. (Sida carpi- 

 noides, DC), I incorrectly referred all to one species, and adopted for it the oldest 

 name. Both are doubtless natives of the warmer parts of America, but are now 

 widely diffused over the world. In the Hookerian herbarium I find only M. tricus- 

 pidatum from the Canary Islands ; but Mr. Webb has well described the Sida car- 

 pinifolia. •]"

* Sidalcea hirsuta : annua; caule stvicto simplici superne cuni racemo denso hirsutissimo ; foliis radi- 

 calibus rotundo-cordatis sublobatis. caulinis 7-9-partitis sectisve, segmentis IJnearibus angustissimplicibus ; 

 calycis hirsutissimi laciniis lineari-lanceolatis acuminatis tubo pluries longioribus ; coccis reticulatis glabri- 

 usculis rostello molli erecto hispido apiculatis. — S. delphinifolia, Gray, PL Fendl. p. 19, S/- Gen. 111. 2. t.

t A plant of EugePs Southern Florida collection (No. 90), distributed by Mr. Shuttleworth under the 

 name of Malva Americana, Linn, var., differs from Malvastrum tricuspidatum merely in its apparently suf- 

 fruticose stems, and its muticous carpels, the three cusps being slightly indicated, but obsolete.
