14. HYDROLEA, L. (Tfioop, water, the plants inhabiting wet places.) 

 — Herbs, or rarely suffruticose plants (widely diffused in warm climates) ; with 

 ovate or lanceolate pinuately 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 placentte very large. Seeds minute, generally 

 striate-ribbed. Styles and placentje occasionally varying 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. 33(3; A. W. Bennett in 

 Jour. Linn. Soc. xi. 275. — Pine-barren ponds, S. Carolina to Florida. Expanded corolla

H. affinis, Gray. More or less spin}^ glabrous throughout or nearly so : stems ascend-

 to Texas. Often confounded with the next. 



H. Caroliniana, Michx. More or less spiny, 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.

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

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

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