ORDER 19. DROSERACEJE. 251 



1 33. Virginica Nutt. St. erect, somewhat compressed, branching; Ivs. oblong 

 ampkxicaul; sla. united below the middle, with 3 in each set. Swamps and 

 ditches. U. S. and Can. Whole plant usually of a purplish hue, 920' high. 

 Lvs. 1^ 2' loug, \ as wide, upper ones lanceolate, lower obfcng-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 petiok ; fls. mostly in 

 3s, axillary, nearly sessile; filaments united above the middle; caps, oblong, muc'.x 

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

 in the last. Aug., Sept. 



ORDER XIX. DROSERACE^E. SUNDEWS. 



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

 ill radical, mostly circinate (rolled from top to base) in vernation ; fls. regular, 

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

 compound, one-celled, with the styles and stigmas variously parted, clefc or united 

 seeds OO in the capsule, albuminous; embryo minute. 



Genera, C, specie* 90. Curious anil interesting plants, scattered over tlio whole- globe 

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

 *he sundew, tc., each half stigma is distinct, hence apparently doubling their number, but in 

 the suborder, Parnassia-, the adjacent halves of different stigmas are united, and thus stand op- 

 posite to the placentas. 



1. DROSERA, L. SUNDEW. (Gr. dpoaog, dew ; from the dcw-liko 

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

 5 ; styles 3 5 each 2-partecl, the halves entire or many-cleft ; cap- 

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

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

 tion circinate. 



Scapes 4 (5 times as long as the leaves Kos. 1 3 



Scapes 12 times as long as the leaves Nos. 46 



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

 fls. white. A curious little plant, r.ot uncommon in bogs and muddy shores. 

 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 flowers 

 open. Caps, oblong. Jn. Aug. 



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

 erect. More delicate than the preceding, in marshes, Ma. to Texas. Lvs. form- 

 ing a rosulato tuft, 8 12" long, the smooth petiole three times longer than the 

 lamina, which is 2 3" wide. Scapes filiform, 3 6' high, the raceme simple 

 or forked, 5 or 6-flowcred. Petals light purple. Caps, globular. Seeds ob- 

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

 Chapman.) 



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

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

 Car. to FJa. and La Not half as large as the last. Lvs. 5 or 6" 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. spatulate- 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 the- 

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

 of small, white flowers, arising 4 7'. Ju. Aug.
