and in Nuttall's specimens, the petals are entire ; but there seems to be no 

 other difference. 



15. C. linearis (Douglas) : stems branching ; leaves very narroAvly linear, 

 obtuse [sheathing at the base, Nutt.'\ ; racemes terminal, one-sided, the low- 

 est pedicel bracteate; petals entire, longer than the calyx. Hook. Jl. Bor- 

 Am. 1. p. 224, t.ll. 



In springy places and on moist rocks along the Oregon, Douglas, Nuttall! 

 — Stems weak, 4-6 inches high. Leaves 2-3 inches long, the uppermost 

 shorter, rather succulent, minutely 3-nerved under a lens. Racemes (and 

 pedicels) somewhat nodding, 4-8-fiowered : pedicels thrice or more the 

 length of the flower. Flowers rather large : petals obovate, entire. Seeds 

 smooth and shining, flat, with a carinate margin. 



16. C. dichotoma (Nutt. ! mss.) : " low, almost csespitose, much branched ; 

 leaves very narrowly linear, acute, sheathing at the base ; racemes terminal 

 and axillary ; flowers (rather crowded) 1-sided, nodding; pedicels about the 

 length of the flowers, the lowest one bracteate ; petals emarginate, scarcely 

 longer than the calyx. 



" In wet places on rocks, near the junction of the Wahlamet with the 

 Oregon. — Very nearly related to C. linearis, but much smaller in all its parts 

 (about li inch high) and densely branched. The flowers and seeds are 

 about i the size of those of C. linearis." Nuit. 



17. C. diffusa (Nutt.! mss.): "stems diffusely dichotomous and procum- 

 bent ; leaves veiny, broadly ovate or deltoid, abruptly attenuate into a petiole, 

 acute; racemes very numerous, terminal and lateral, subcorymbose, 5-9-floAv- 

 ered ; pedicels slender, at length recurved, the lowest one bracteate ; petals 

 emarginate, a little longer than the calyx. 



" In pine Avoods, a few miles above Fort Vancouver. — A very remarkable 

 species, with much the habit and appearance of Stellaria media, except 

 that the leaves are alternate. The stem is many times dichotomous and 

 spreadmg widely over the ground. Radical leaves on long petioles ; those 

 of the upper leaves somewhat margined and about the length of the limb. 

 Pedicels several times longer than the flowers, sometimes geminate; the low- 

 ermost longest. Flowers rather small: petals pale rose-color. Seeds flat, 

 very minutely and regularly rugose-puncticulate, with obtuse margins."

6. MONTIA. Linn.; Lam. ill. i. 50; Gartn.fr.t. 129. 



Sepals 2, rarely 3, persistent, suborbicular. Petals 5, hypogynous, ungui- 

 culate, with the claws a little connate ; 3 of them somewhat smaller. Sta- 

 mens 3, inserted on the claws of the smaller petals, ver^^ rarely 4 or 5. Styles 

 very short, almost separate, spreading. Capsule 3-valved, 3-seeded. Seeds 

 turgid, minutely tuberculate, large. — A very small glabrous procumbent rather 

 fleshy herb, growing in water or wet places; common in Europe; rare in 

 North and South America. Leaves opposite, spatulate. Raceme few-flow- 

 ered, terminal.
