narrow linear calyx lobes. Root perpendicular, slender. Flowers 

 rose-colored. Stem three to four inches high. Blooms in August. 

 Habitat — Marshy soil of Grand Isle. 



4. Sabbatia Oligophylla. — Stem erect, somewhat four-angled, simple 

 and scape like. Leaves opposite, long linear, lanceolate, acute, 

 clasping, remote, the stem bearing but two pairs of leaves. Radical 

 leaves nine, clustered, obovate, narrowed at the base, and spatulate 

 lanceolate sessile. Flower solitary, terminal. Corolla large, rose- 

 colored, nine parted, three times as long as the partially reflexed 

 linear calyx lobes, four bracted, two of the bracts nearly as long as 

 the petals, and the other two twice as long. Stem eight inches 

 high. 



Habitat — Grows in the pine and oak woods beyond Chicotville, St. 

 Landry, in sandy soil, and blooms in August. 



This species differs from Sabbatia-choroides, in having the stem 

 angled and the leaves clasping. It has but two pairs of cauline 

 leaves, and the others are all radical and clustered, and the flowers 

 are bracted. 



It differs from S. Boykinii in having four instead of two bracts, 

 and the calyx lobes are not lanceolate, but narrow, linear and reflexed. 



The S. gentianoides, which it seems to resemble, has no bracts. 



5. Hydrolea Leptocaulis. — Stem spiny, ascending, smooth, simple 

 or branched. Leaves varying from oblong lanceolate to lanceolate 

 from three to five inches long, acute, smooth, glossy and shining, 

 tapering into a petiole. Flowers large, axillary, mostly solitary, 

 sometimes two in a cluster, pale blue, short-peduncled, almost sessile. 

 Corolla five parted, divisions oblong obtuse with five triangular 

 white spots at the base. Calyx lobes ovate lanceolate, smooth, two- 

 thirds as long as corolla lobes. Stamens and styles exerted. 



Habitat — Is found in the bayou near Washington, St. Landry. 

 The outside appearance of this species is so much different from the 

 H. quadrivalvis, that I considered it advisable to make a new species 

 of it, though it may only be considered a variety of the latter. The 

 leaves are larger, more deep green and glossy, the flowers are much 

 larger and have a brighter color, besides being distinguished by the 

 white spots at the base of the petals. The calyx lobes are not 

 linear, but ovate lanceolate. 



6. Hydrolea Ludoviciana. — Stem erect, simple or branched, fis-
