Order 19.— DROSERACELE. 251 



1 E. Virginica Nutt. St. erect, somewhat compressed, branching; lvs. oblong 

 amplezicaul ; sta. united below the middle, with 3 in each set. — Swamps and 

 ditches. U. S. and Can. Whole plant usually of a purplish hue, 9 — 20' high. 

 Lvs. I2 — 2 J' long, 2 as wide, upper ones lanceolate, lower oblong-ovate, all very 

 obtuse, glaucous beneath. Fls. 5" diam., terminal and axillary. Pet. about twico 

 longer than the calyx. Glands ovoid, orange-colored. Caps, ovoid-oblong, 

 acutish. Jl. — Sept. 



2 E. petiolata Ph. Lvs. oblong, narrowed at base into a petiole ; fls. mostly in 

 3s, axillary, nearly sessile; filaments united above the middle; caps, oblong, much 

 longer than the sepals. — Swamp3 S. States, N. to N. J. St. about 2f high. Lvs. 

 1 — 3' long, rounded-obtuse, with a short but distinct petiole. Fls. smaller than 

 in tho last. Aug., Sept. 



Order XIX. DROSERACEvE. Sundews. 



Herbs growing in bogs, often covered with glandular hairs, with lvs. alternate or 



«11 radical, mostly circinate (rolled from top to base) in vernation ; Jls. regular, 



cypogynous, 5-merous, the sepals, petals and stamens persistent (withering) ; ova. 



compound, one-celled, with tho styles and stigmas variously parted, cleft or united 



seeds OO in the capsule, albuminous ; embryo minute. 



Genera, 6, species 90. Curious and interesting plants, scattered over tlio whole glob* 

 wherever marshes are found. Tho halved stigmas are their most singular characteristic. In 

 ♦he sundew, &c, each half stigma is distinct, hence apparently doubling their number, but ia 

 tho suborder, Parnassia?, the adjacent halves of different stigmas are unitod, and thus stand op- 

 posite to the placenta}. 



i. DROSERA, L. Sundew. (Gr. dgoooq, dew ; from tho dew-like 

 secretion.) Sepals 5, united at base, persistent ; petals 5 ; stamens 

 5 ; styles 3 — 5 each 2-parted, tho halves entire or many-cleft ; cap- 

 sule 3 — 5-valved, 1 -celled, many-seeded. — U Small aquatic herbs. Lvs. 

 covered with reddish, glandular hairs, secreting a viscid fluid. Verna- 

 tion circinate. 



Scapes 4 — G times as long as tho loaves Nos. 1 — 3 



Scapes 1 — 2 times as long as tho leaves Nos. 4 — 6 



1 D. rotundifolia L. Lvs. orbicular, abruptly contracted into tho hairy petiole; 

 fls. white. — A curious little plant, not uncommon in bogs and muddy shore9. 

 Whole plant of a reddish color, like the other Sundews, and beset with glandular 

 hairs which are usually tipped with a small drop of a clammy fluid, glistening 

 like dew in the sun. Lvs. about 5" broad and with the petioles 1 — 2' long. 

 Scape slender, 5 — 8' high, the racemes uncoiling as the small white flower3 

 open. Caps, oblong. Jn. — Aug. 



2 D. minor. Lvs. obovate, cuneiform at base, the petioles naked ; fls. purple ; scapo 

 erect. — Moro delicate than tho preceding, in marshes, Fla. to Texas. Lvs. form- 

 ing a rosulate tuft, 8 — 12" long, the smooth petiole three times longer than tho 

 lamina, which i3 2 — 3" wide. Scapes filiform, 3 — 6' high, the raceme simplo 

 or forked, 5 or G-flowered. Petals light purple. Caps, globular. Seeds ob- 

 long, tubercled. May. (D. brevifolia (3. major Torr. & Gr. D. intermedia 

 Chapman.) 



3 D. brevifolia Ph. Lvs. cuneiform-spatulate, forming a small, dense tuft (1' 

 diam.) ; petioles very short, hairy; fls. few, rose colored. — In wet, springy places, 

 Car. to Fla. and La. Not half as large as the last. Lvs. 5 or G" long, 1 — 2" 

 broad, flat on the ground, forming a round, compact rosette. Scapo 2 or 3' 

 high, bearing one to three conspicuous flowers. Capsule roundish. Apr. 



4 D. longifolia L. Lvs. spalulale- oblong or obovate, ascending, alternate, tapering at 

 base into a long, smooth petiole; scape declined at base; petals white. — Slender and 

 delicate, in similar situations with the last. Lvs. slender, ascending, crenate, 

 beset with numerous hairs tipped with dew-like drops, — length, including tho 

 petioles 2—3'. Candex lengthened, declinate. Scape bearing a simple racem, 

 of small, white flowers, arising 4 — T. Jn. — Aug.
