14. HYDROLEA, L. {TdwQ, water, the plants inhabiting wet places.) 

 — Herbs, or rarely sult'ruticose plants (widely ditf nsed in warm climates) ; with 

 ovate or lanceolate pinnately veined entire leaves, numerous on the stems, often 

 with a spine in the axils, and clustered blue or rarely white flowers. Sepals dis- 

 tinct to the base. Corolla rotate or very open campanulate, 5-cleft. Stamens 

 about the length of the corolla : filaments dilated at the insertion. Capsule 

 globular; the fleshy or spongy placentae very large. Seeds minute, generally 

 striate-ribbed. Styles and placenta? occasionally var3'ing to 3. — Ours appear to 

 be perennials, flowering through the summer. 



H. COrymbosa, Ell. Spineless or nearly so : stem slender, a foot or two high, above 

 minutely pubescent: leaves lanceolate, nearly sessile (an inch or so long), glabrous: 

 flowers in a terminal corymbose cyme : sepals linear-lanceolate, villous-hispid ; shorter 

 than the corolla: filaments and styles long and filiform. — Sk. i. 330; A. W. Bennett in

H. afKnis, Gray. More or less spin\% glabrous througliout or nearly so : stems ascend- 

 ing : leaves lanceolate, somewhat jietioled (2 to 5 inches long) : flowers in short axillary 

 leafy-bracted clusters : sepals ovate, equalling the corolla : styles shorter than the cajjsule. 

 — Man. ed. 5, p. 370. H. leptocauUs, Feathcrman, Louisiana Univ. Rep. 1871. — S. Illinois

H. Caroliniana, Michx. More or less spin}', sparsely villous-hispid or the leaves 

 nearly glabrous : stem ascending : leaves lanceolate, short-petioled (3 or 4 inches long) : 

 flowers in short axillary clusters, or solitary in the upper axils: sepals linear or linear- 

 lanceolate, about the length of the corolla: styles shorter than the capsule. — Fl. i. 177.

 foot or two liigh, paniculately branched at summit : leaves ovate, sometimes ovate-lan- 

 ceolate (8 to 20 lines long) : flowers clustered at the end of the branches : sepals lanceolate, 

 very villous-hirsute, shorter than the corolla ; this an inch broad when expanded : filaments 

 and especially the styles long and filiform. — Fl. Arkans. in Trans. Am. Phil. Soc. ser. 2,
