the throat, the tube about twice as long asthe calyx, and longer than the 
limb: filaments flattened, slightly longer than the anthers: style filiform, usu- 
ally somewhat exserted: nutlets rounded. In damp woods, California to 
Alaska, and Hudson Bay to Michigan, Nebraska and the Rocky Mountains. 
M. platyphylla Heller Bull. Torr. Bot. Club xxvi, 548. Stems weak, 
16-30 inches high, branched above, the branches slender and spreading: leaves 
all thin, light green, papillately roughened above; radical leaves usually 
about a foot long including the peticle, of about 8 inches, which is rough on 
the margins; blade broadly ovate, 3-4 inches broad, abruptly acuminate, usu- 
ally cordate at base; lower stem-leaves broadly ovate, abruptly acuminate, 
on petioles about an inch long; upper ones ovate-lanceolate, gradually acu- 
minate, sessile or nearly so, contracted at base: flowers in loose terminal pan- 
icles: pedicels slender, 3-7 lines long, pubescent with short appressed hairs: 
sepals Jinear-lanceolate, 3—4 lines long, ciliate: corolla bright blue, or turning 
rose-color 6-8 lines long, broad funnelform, the tube about 2 lines long, 
the acutish lobes with broad sinuses at base: anthers oblong: style slightly 
exserted. In rich moist ground, western Washington and Oregon, 
M. nutans. Stems simple, 1-8 from the crown of a thick branching root, 
3-10 inches high, very leafy to the top: leaves oblong to lanceolate or the 
l west sometimes spatulate, the largest ones in the middle of the stem 1-3 
inches long, mostly sessile by a broad base or the lowest sometimes petioled, 
all papillose-granulate above, not at all pubescent: flowers in a dense terminal 
drooping panicle, sessile or on short pedicels: sepals lanceolate, barely 2 
lines long, obscurely ciliate: corolla 6-8 lines long, funnelform, with a broad 
purple or pinkish tube twice or thrice as long as the calyx: filaments as proad 
as and fully as long as the anthers: style slender, often slightly exserted. On 
the north side of high ridges, eastern Oregon and Washington. 
15 PNEUMARIA Hill Veg. Syst. vii, 40, t. 36. 
_Glabrous fleshy perennials with alternate leaves and small blue 
pinkish or white flowers in loose terminal leafy-bracted racemes. 
Calyx-lobes somewhat enlarged in fruit. Corolla tubular-campanu- 
late, crested in the throat, 5-lobed, the lobes imbricated in the bud, 
slightly spreading. Filaments scarcely exserted. Ovary 4-divid- 
ed; style slender. _ Nutlets erect, fleshy, attached just above their 
bases to the somewhat elevated gynobase, smooth and shining, 
acutish-margined, becoming utricular-like when mature. 
P. maritima Hill 1. c. 40, t. 37,<fig.3. Very smooth, pale and glau- 
cous, much branched and spreading; leaves fleshy, ovate, obovate, or spat= 
ulate-oblong, an inch or two long, upper surface becoming pustulate: flowers 
small, 3 or 4 lines long, on long and slender pedicels: tube of the blue or 
whitish-corolla hardly as long as the limb and shorter than the ovate-tri- 
angular lobes of the calyx, the crests in the throat evident: filaments rather 
narrower and much longer than the‘anthers: nutlets acute, fleshy-herba- 
ceous, in ave becoming utricular, the scar small. Along the Coast, 
Puget Sound to Alaska, and Hudson Bay'to,New England also Europe. 
16 MYOSOTIS. L. Gen. n.‘180. 
Low annual biennial or perennial herbs with alternate leaves 
and small blue pink or white flowers in so called spikes or racemes. 
Calyx 5-parted or 5-cleft. Corolla salverform or rotate, the tube 
rarely surpassing the calyx, the throat with small and blunt crests 
at the base of the small and rounded lobes: these convolute in the
