be distinct. Tlie youna; fruit is more slender, sometimes ineiirved, and of 

 tlie sjmie diameter tliroiiyhoiil. It is |)rol)al)ly tlie (K. lieterojiliylla of 

 S])aeli ; but we do not ol)serve tlie deejjly siuuate-toullied lower leaves, nor 

 the hirsute-lomentose ovaries. 



3. CK. Drummondii (Hook.) : elothed with a soft pubescenee ; stem de- 

 cumbent ; leaves ovate-elliptieal or oblonjr, rather obtuse ; the lower ones 

 tapcrini!; into a petiole, somewhat sinuately tooliied, the upi)er ones obseurely 

 denticulate ; flowers {very larsje) axillary ; tube of the calyx equalling in 

 length the segments and the hirsute ovary; petals much longer than the 

 slightly declined stamens, a little exceeding the calyx-segments ; capsules 

 (iminature) cylindrical, elongated, hirsute-i)ubescent, slightly pedicelled. —

Texas, Drummnnd ! — Stem about 2 feet long, thick. Floral leaves as 

 long as the tube of the calyx. Corolla about 3 inches in breadth. Ovary 

 an inch long : style about the length of tlie petals. 



4. CE. Jaincsii: canescently strigose; stem decumbent; leaves oblong- 

 lanceolate, rcpandly denticulate, acute ; flowers (ver^^ large) ]taniculate at 

 the summit of the stem ; tube of the calyx (very long) more than twice the 

 length of the segments and many times longer than the ovary ; petals 

 scarcely longer than the slightly declined stamens ; anthers very long, fixed 

 below the middle ; style exseried ; ovary cylindrical. 



On tlie Platte or Canadian Kiver, Dr. James ! — Leaves (upper ones) 3-5 

 inches long, clothed ecpially on both sides with a short appressed rough 

 pubescence. Bracts rat lier sliortcr than the ovary. Calyx eaiieseent : the 

 tube rather stout, 3-4 inches long, a little curved, slightly dilated at the 

 summit. Petals apparently' yellow, turning to rose-color. Anthers three- 

 fourths of an inch in length. Stigmas linear, rather thick. Ovary less than 

 an inch in lengUi, canescent. Fruit unknown. — ^Wc have only an imperfect 

 specimen of this apparently very distinct species. 



5. CE. HooJceri: canescently pubescent and somewhat villous; stem 

 erect, angled ; leaves lanceolate, sessile, rather acute, obseurely denticulate, 

 not undulate ; flowers (large) sessile, in a leafy spike ; calyx villous ; the 

 tube twice the length of the ovarj', rather shorter than the slightly acuminate 

 segments; petals obcordate, about the length of the style; siignias linear, 

 somewhat thickened; capsules short. — CE. odorata? Hook. S^' Am..' lot. 

 Beechei/, suppl. p. 343, scarcely of .Jacq. 



California, Douglas ! — Stem stout and tall, strict, strongly angled: pubes- 

 cence soft and minute, with long and coarser hairs intermixed. Petals 

 apparently yellow, turning to rose-color. Ripe fruit unknown. — This plant 

 differs from CE. odorata (which is said to be a native of Patagonia) in its 

 plane leaves, which are not attenuated to a sharp point, its perfectly sessile 

 ovaries, &c., and is besides more hairy. In the collection of Dr. James, 

 made near the sources of the Platte or Canadian, we have a fragment ap- 

 parently of the same species. 



-f- — 6. CE. rhombipetola (Nutt. ! mss.) : minutely pubescent ; stem tall, 

 erect ; leaves linear-lanceolate, obscurely denticulate, acute ; the lower ones 

 elongated, tapering into a short petiole ; the radical ones somewhat jMnnatifid 

 or sinuate; spike strict, elongated ; bracts foliaceous, much shorter than Uie 

 (rather large) flowers; tube of the calyx very slender, rather longer than 

 the segments and several times longer than the ovary ; petals rhombic- 

 obovate, acute or acuminate, shorter than the style and about the length of 

 the stamens ; anlliers inserted near the base ; capsules very small, cylin- 

 drical.
