California, Douglas ! — This species is not noticed in Hooker and Arnotl's 

 account of DonijUis's Caiilinnian collfftion : our specimen is from a set pre- 

 sented l)y the London llorticulturat Society. It is a slender plant, scarcely 

 a foot high ; the leaves and ovaries pubescent with minute s])readin£j hairs; 

 the llowcrs few (yellow) and near the summit. It seems rather ditHcult to 

 ascertain which is the true ffi. denlata of Cavanillcs; but our plant airees so 

 minutely with the description of Mr. Si)nch (from a specimen of Dombey) 

 that we can hardly sn])pose it to be a ditlc'rent species. We want the fruit, 

 but it is evident tluit the capsule is linear. Tiie leaves are about half an inch 

 long, and less than a line wide. 



57. CE.parvula (Nutt. ! mss.) : almost <,dal)n)us (minutely puberulent with 

 spreading hairs) ; stem much branched, slender; leaves very narrowly linear, 

 obtuse, nearly entire ; (lowers (very small) mostly towards the end of the 

 branches; tube of the calj^x infundibulifi)rm-obconic, about the length of the 

 lanceolate-oblong segments, many times shorter than the filiform f)vary; pe- 

 tals (scarcely a line long) obovate, entire, about tlirice the length of the longer 

 stamens and" the large stigma; capsules linear, elongated, slightly 4-sided, 

 torulose, nearly straight. 



Plains of the Rocky Mountains towards Lewis's River, Nuttall ! — Plant 

 4-8 inches high. Leaves nearly an inch long, scarcely half a line wide. 

 Capsules almost filiform, 6-10 lines long, apparently not attenuated towards 

 the summit. Stigma very large for the size of the flower. 



58. CE. contorta (Hook.) : glabrous; stem weak, branching ; leaves linear, 

 entire; flowers numerous, minute; tube of the calyx infundibuliform, as long 

 as the segments ; capsules cylindrical, elongated, curved or contorted, torulose.

Sandy barren soil on the interior banks of the Oregon River, X)oM£-^as. — 

 Plant .3-5 inches high, with the habit of Ejiilobium : the stem liranching 

 from the base. Petals scarcely a line long, ecjualling the tube of the calyx. 

 Capsules an inch or more in length, similar to those of Epilobium. Seeds 

 ovate, angled. Leiim. — This sjiecies is unknown to us, and seems difierent 

 from any of Mr. Nuttall's extensive collection in this genus, unless it should 

 prove to be the same with his CE. parvula, in which the capsules may be- 

 come curved when old. 



59. CE. abjssoides (Hook. & Am.) : low, branched from the base, puberu- 

 lent ; lower leaver much largest, oblong-lanceolate, unecjually toothed, at- 

 tenuate into a petiole, rather shorter than the stems, the ujjper ones linear ; 

 spike leafy, unilateral, circinate ; ovaries very slender, sessile ; petals about 

 the length of the filaments, shorter than the style ; capsules contortuplicate, 

 striate, lorulose. Hook. Sf- Arn., hot. Beechey,'suppl. p. 340; Hook. ic. pi.

California, Dottglas. — We have not seen tliis species. The stems are 

 said to be 3-5 inches long, ascending ; the central one erect and floriferous 

 from the base ; the flowers copious, retaining their color (pale yellow) when 

 dry; the upper portion of the raceme recurved until the flowers expand ; the 

 capsules about an inch long, and not half a line thick at the base, somewhat 

 terete, slightly attenuate at the summit. The size of the flowers and the 

 form of the calyx-tube are not mentioned. 



60. CE. epilobioides (Nutt. ! mss.) : almost glabrous ; stem slender, erect, 

 branching above ; leaves linear-oblong, obtuse, remotely denticulate, attenu- 

 ate into a short petiole ; flowers few, towards the summit of the branches ;
