deis ohtusiusculis, diiobus paullo brevioribus ; corolla ultrapollicari 

 pallide aurantiaca ea C. Mexicance referente sed inferne magis atten- 

 uata. — Ravines 150 miles north of Batopilas, Palmer, 402. Singular

SIDALCEA. 



M. Alphonse De Candolle, in the Preface to the " Caiques des Dessius 

 de la Flore du Mexique de Mo^ino et Sesse," several years ago pointed 

 out the fact that the original Sida irialvcejlora, DC, was not the plant 

 of the Botanical Register, and not the plant taken up by me as Sidalcea 

 malvcejlora. Also I had recognized Mo^ino's drawing to belong to what 

 I had named Sidalcea humilis, the common species of the Californian 

 coast ; but I had deferred calling attention to it until I could revise 

 the whole genus and rectify the synonymy. In consequence of this 

 inadvertence Mr. Greene did not know of this correction when he 

 published his revision of Sidalcea, a year or more ago. For the pres- 

 ent it suffices to note that the name Sidalcea malv^eflora belongs 

 to the Sida mcdvcBJlora, Hook. & Arn., &c., and has Sidalcea humilis. 

 Gray, PI. Fendl., for a synonym ; while the other names, S. Neo- 

 Mexicana and *S'. Oregana of PI. Fendlerianse, come into use for the 

 interior-country species. 



Two of the annual species which, in the Botany of California, Mr. 

 Watson inadvertently combined, are quite distinct, and were fairly 

 well characterized in the original account of the genus, viz. S. Hart- 

 wegi and »S'. hirsuta. A year ago I found them growing near each 

 other, in exsiccated pond-holes or pieces of depressed ground in f^rain- 

 fields, on the Rancho Chico of the esteemed Gen, John Bidwell, where, 

 as I suppose, Hartweg found them. The former also grows on elevated 

 ground along the borders of Chico Cafion. 



S. HARTw-Kfa, Gray, PI. Fendl. 20, & in PI. TTartw. 300, is 

 slender and much smaller than the other; with only fine and short 

 pubescence on the higher parts, loosely and panicnlately branching, 

 and sparsely flowered ; the corolla of a deep pink purple and from one 

 third to two thirds of an inch long. The carpels are whole and closed 

 when they separate from the axis, are strongly reniform-incurved or 

 with basal portion straighter, the whole of the firm dorsal portion 

 strongly rugose-reticulated, the rug.c sharp and salient, especially on
