E. tomentosum, Benth. 1. c. White-tomentose with a dense coat of short villous 

 hairs, sometimes rusty-colored with age, 6 to 10 feet high : branches leafy to the top . 

 leaves oblong or oval, rigid, obtuse (2 to 4 inches long) : cymes at length broad : calyx 

 densely and corolla slightly villous, the latter somewhat salverform and about twice the

 high: leaves lanceolate (3 to 6 inches long), irregularly more or less serrate, sometimes 

 entire, whitened beneath between the reticulations by a minute and close tomentum, above 

 glabrous : cymes in an elongated naked thyrsus: corolla tubular-funnelform (half an inch 

 long), thrice the length of the slightly and sparsely hirsute calyx. Wnjandia Californica, 

 Hook. & Arn. Bot. Beech. 364, t. 88. Dry hills, rather common in California. Infusion 

 of the leaves in spirit used as a tonic, under the name of Yerba Santa. 



E. angustifolium, Nutt. Glabrate and glutinous : leaves narrowly linear or narrowly 

 lanceolate, rigid, and the margins at length revolute : corolla 2 or 3 lines long, short-funnel-

14. HYDR6LEA, L. (Td<og, water, the plants inhabiting wet places.) 

 Herbs, or rarely suffruticose plants (widely diffused 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 placentas very large. Seeds minute, generally 

 striate-ribbed. Styles and placentas 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. 330; A. W. Bennett in 

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

 two-thirds of an inch in diameter. 



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

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

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

 Man. ed. 5, p. 370. H. leptocaulis, Featherman, Louisiana Univ. Rep. 1871. S. Illinois 

 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.

H. OVata, Nutt. Spiny, minutely soft-pubescent and above slightly hirsute : stems a 

 foot or two high, 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. scr. 2, 

 v. 196; Chois. Hydrol. t. 1 ; A. W. Bennett, 1. c. 270. 77. oratifoti'a, Raf. Neobot. (1836),
