SIDALCEA MALVACE. 101 
what decumbent, hairy or nearly glabrous: leaves round-cordate, crenate, 
more or less strongly 5-7 lobed; peduncles axillary, solitary or clustered, 
1-3 lines long: calyx-lobes acute, becoming very broad and enlarged in 
fruit: petals 2-3 lines long: capsule transversely reticulate-rugose. A 
weed from Europe, on the Coast from Puget Sound to Lower California. 
M. rorunpirotia L. Stems prostrate from a perennial root, 6-20 inches 
long, leaves cordate-orbicular, obtusely 5-lobed and crenate on elongated 
ubescent petioles: pedicels axillary, 1-flowered involucral bracts ob- 
ong-linear: calyx lobes acutely triangular: petals 4-6 lines long, pale 
purple: carpels numerous, wrinkled. Roadsides and waste grounds; in- 
troduced from Europe. 
2 SIDALCEA Gray Pl. Fendl. 18. 
Herbs with more or less deeply lobed leaves and purple or 
white flowers in a terminal raceme or spike: involucre none: ca- 
lyx 5-parted. Staminal column double, the filaments of the 
outer series united usually into 5 sets opposite the 5 petals, of 
the inner distinct. Styles filiform, stigmatic on the inner face. 
Carpels 5-9, with a single ascending seed in each, separating at 
maturity from the short axis, sometimes beaked, indehiscent. 
Ours all perennials. 
* Pubescence not hirsute. 
S. glaucescens Greene Bull. Cal. Acad: 3,77. Minutely stellate-pub- 
escent, and somewhat glaucous throughout: stems numerous and decum- 
bent, 2 feet high, rather slender: leaves, even the lowest, palmately 5-7- 
parted, the crenate divisions 3-5 lobed or toothed, those of the uppermost 
entire: raceme simple, loosely flowered: divisions of the calyx attenuate- 
acuminate: petals deep purple, obtuse or at most only truncate: carpels 
with distinct longitudinal reticulations. Oregon, Hall; station not noted 
to Mount Shasta and the Sierra Nevada Mountains, California. 
S. malveflora Gray Pl. Wright i, 16. Stems 2-4 feet high, erect ora 
little decumbent, mostly solitary from a fusiform root: hirsute below and 
on the calyx and pedicels; short, stellate pubescence wanting: leaf mar- 
gins ciliate: radical leaves orbicular with open sinus and 5-9 shallow, 
crenate-incised lobes : the uppermost cauline 5-7-parted into linear, entire 
segments: raceme usually solitary, virgate : pedicels erect, twice the length 
of the calyx, the lobes of which are broadly ovate, acuminate: carpels 
smooth, depressed. Idaho to Colorado, New Mexico and Arizona, 
S. virgata. Steilate pubescent throughout: stems numerous from the 
thick somewhat woody root, spreading or ascending, sparingly branched, 
6-24 inches high: leaves orbicular in outline, 1-4 inches in diameter all 
petioled, the lower more or less deeply 5-7 lobed, the obtuse, oblong lobes 
coarsely toothed at the apex, densely stellate-pnbescent beneath, more 
sparsely so with more simple appressed hairs above: upper more deeply 
lobed or parted with linear-acute or acutish entire or sparingly toothed 
segments: flowers bright purple in virgate racemes: bracts setaceous, 
calyx lobes lanceolate, acuminate, 2-3 lines long, rounded, or retuse and 
minutely erose-dentate at the apex. Common on dry hillsides, Willam- 
ette valley tothe northern boundry of California. 
* * Pubescence of two kinds, hirsute and stellate. 
S. spicata Greene l. c. 76. Equably hispid-hirsute throughout, the 
hairs simple and not deflexed, stellate pubescence sparse, mostly confined 
to the under surface of the leaves and the calyx where it is minute: stems 
2 feet high, strict and simple, or with a few short branches above: lowest 
leaves orbicular, lobes and teeth shallow, rounded; cauline parted into 7,
