12. S. oregana Gray. Oregon Checker. Stems few from a woody root- 

 crown, nearly naked above, usually paniculately branched, 1 to 5 feet high; herb- 

 age and inflorescence finely stellate-pubescent or the lower parts glabrous; blades 

 of lower leaves orbicular, shallowly toothed or cleft (rarely deeply parted), 1 

 to 4 inches wide; blades of cauline leaves incisely parted with the lobes toothed 

 or cleft, or the blades of the uppermost pedately divided into 5 to 7 lanceolate, 

 linear or 3-lobed divisions; petioles 2 to 7 inches long; spikes several, 1 to 4 inches 

 long or much elongated in fruit, long-peduncled; bracts narrowly linear or subu- 

 late; corolla rose-pink, in the staminate 5 to 8 lines long, in the pistillate 3 to 4 

 lines long; carpels serai-orbicular, slightly beaked, glabrous and smooth or shal- 

 lowly reticulate dorsally, 1 line long. 



Moist meadows or stream banks, 2600 to 6000 feet: Siskiyou Co., and south 

 perhaps to Napa Co.; Modoc Co. North to Washington, east to Wyoming and 

 Utah. May-Aug. 



Note on variation. — The pubescence and racemes are especially variable. There is exhibited: 

 stellate pubescence throughout; stellate pubescence only on the inflorescence and calyx; hirsute 

 bristles on the herbage ; herbage more or less glabrous ; spikes short or elongated : these factors 

 in various combinations give expression to the group here known as Sidalcea oregana and its 

 varieties and forms and intermediates. The herbage, inflorescence and calyx may be (a) stellate- 

 pubescent throughout (typical S. oregana), or (b) the stems and petioles may be glabrous (or 

 with only a few hairs below) and the inflorescence stellate-pubescent (intergrade towards var. 

 spicata: Sissou, Jepson 5784), or (c) the herbage may be bristly-pubescent with stellate-pubes- 

 cent inflorescence and calyces, or agaia (d) the herbage may be bristly-pubescent with stellate- 

 pubescent inflorescence and stellate-pubescent and hirsute calyces (var. spicata). There are 

 intergrades amongst these various phases. Spikes capitate or elongated have no geographic 

 significance and do not seem to be a criterion otherwise.
