 lanceolate 6-18 lines long, acute, clasping, those of the stem distant:

 bent and matted : leaves elliptic-ovate, 4-6 lines long : flowers few, on more 

 or less elongated pedicels; petals bifid, twice the length of the rather ob-

6 ALSINE L. (notWahl. Fl. Lap. 127.) 



Low spreading herbs, usually preferring shaded or moist 

 places, with mostly 4-angled stems, flat, rarely acerose ; leaves 

 and small white flowers in cymes or solitary. Sepals 5, rarely 4, 

 somewhat united at base. Petals as many, rarely wanting, al- 

 ways more or less deeply 2-cleft, often divided almost to the 

 base, thus appearing as 10, often perigynous. Stamens 10, or by 

 abortion 3-8, styles 3, sometimes 2, 4 or 5, opposite to as many 

 sepals. Capsule globose to oblong, 1-celled, dehiscent to below 

 the middle with twice as many membranous valves as styles. 

 Seeds numerous, reniform-globose or laterally compressed. 



§ 1 Myosoton Monch Method. 225, (as genus). Styles 5, al- 

 ternate with the sepals. Leaves ovate, acute. 



A. aquatica. StellaHa aqvalica Scop. Perennial: stems strongly an- 

 gled and somewhat pubescent: leaves large ovate or ovate-lanceolate, 

 acute, the upper sessile, cordate ; the lower petiolate : pedicels glandilar- 

 viscid deflexed in fruit : petals \y z -2 times as long as the campanulate 

 glandular-pubescent calyx : styles 5, alternate with the sepals : seeds nu- 

 merous dark- colored tuberculately roughened. At Nanaimo, Brit. Colum- 

 bia, perhaps Washington ; introduced from Europe. 



§ 2 Eustellaria Fenzl. Styles 3 or 4. 



* Petals deeply 2- parted, sometimes minute or wanting : segments 



narrow. 



+- Lower leaves contracted to slender petioles. 



A. media L. Sp. i. 272. StellaHa media Cyr. Char. Ccmm. 36. Gla- 

 brous or nearly so: stems weak and spreading, rooting at the lower joints, 

 marked by a pubescent line : leaves ovate to oblong-ovate, 3-9 lines long 

 on hairy petioles or the uppermost sessile : pedicels slender, 4-6 lines long, 

 deflexed in fruit: bracts foliaceous : petals oblong, deeply divided, shorter 

 than the pubescent sepals : stamens 3-10: capsule oblong-ovate 2-3 lines 

 long, equalling or exceeding the calyx. A common weed in shady places 

 and cultivated grounds. Said to be introduced from Europe. 



A. nitens Greene Bot. Bay. Reg. 33. StellaHa nitens N«tt. T. & G. Fl. i. 

 185. Smooth and shining, often hairy at base: stems slender, 3-8 inches 

 high erect or spreading, dichotomously branched with the flowers in' the 

 forks : leaves lanceolate,, 3-0 lines long, acute, the lower shortly petiolate :
