leaves lanceolate (or the lower ovate-lanceolate), acute, sessile or very 

 shortly petiolate, 3 to 6 lines long: flowers alternate, the very short 

 pedicels lateral, with a pair of minute bractlets near the middle : calyx 

 o or 4 lines long, with a very short broad spur ; teeth nearly equal, 

 and tube pubescent within; petals purple, 3 lines long; stamens 11, 

 nearly or quite equalling the tube : capsule gibbous, 2 lines long, about 

 10-seeded : seeds nearly a line broad, with a narrow thick margin. — 

 Specimens, thus referred by Koehne, have been collected by Mr. A. B. 

 Langlois in low grassy places along Vermillion Bayou, near Vermil- 

 lionville, Western Louisiana, April, 1884. The species is otherwise 

 known only from S. America (S. Brazil and Buenos Ayres to Bolivia), 

 but the evidence is all in favor of its being indigenous wdiere it was 

 found in Louisiana. Koehne, in his monograph of the LytliracecB 

 (Engler's Botanische Jahrblicher, 2. 148), describes the seeds of this 

 species as having a thin narrow wing, a character which he uses in 

 forming his groups. In a recent letter he admits that he has found this 

 character inconstant, and of little value even for distinguishing species. 

 The above description is drawn from Louisiana specimens. 



CEnotiiera Havardi. Perennial, with l)ranching caudex and nu- 

 merous short slender simple or branching stems, canescent with short 

 close pubescence : leaves linear-lanceolate, attenuate at each end, irregu- 

 larly sinuate-pinnatifid, i to 2 inches long: flowers axillary, sessile, 

 erect in the bud, puberulent; calyx-tube 1^ to 2 inches long, slightly 

 dilated above, the attenuate tins of the lobes coherent ; petals orange- 

 yellow turning red, oblong-lanceolate, acute, a half to one inch long: 

 stigmas short (1 or 2 lines long) : cap^ule oblong-ovate, 4-angled and 

 the valves strongly ribbed, about o lines long. — Collected on prai- 

 ries near IMorfa, Western Texas, by Dr. V. Havard, U. S. A., July, 

 1883. Scanty specimens were also collected by Mr. Wright in 1851 

 in a prairie-dog town near Leon Springs. A peculiar species of the 

 Euoenothera section, not falling readily into any of the recognized 

 groups, but perhaps most nearly related to (E. canescens. 



IIauya Califohnica. Shrubby, erect (6 to 8 feet high), the slen- 

 der branches grayish : leaves somewhat fascicled, narrowly oblong- 

 lanceolate, acute, 3 to 6 lines long, canescently puberulent: flowers in 

 terminal racemes with small leafy bracts, shortly pedicellate, bright 

 scarlet; calyx-tube cylindrical, 8 to 12 lines long, the lanceolate lobes 

 equalling the obovate petals (3 lines long) : stamens in two unequal 

 series, the outer equalling the petals ; anthers scarcely apiculate : 

 stigma discoid : capsule narrowly oblong, 6 to 9 lines long, long- 

 persistent. — On Cedros Island, Lower California; collected by Dr.
