ORDER 19. DROSERACE^E. 251 



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

 ampkxicaul; 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. Is 2^' tong, % as wide, upper ones lanceolate, lower oblong-ovate, all very 

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

 acutish. Jl. Sept. 



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

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

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

ORDER XIX. DROSERACE^E. SUNDEWS. 



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

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

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

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

 seeds OQ in the capsule, albuminous ; embryo minute. 



Genera, 6, species 90. Curious and interesting plants, scattered over tho whole globe 

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

 *he sundew, &c., each half stigma is distinct, henco apparently doubling their number, but in 

 the suborder, Parnassian, the adjacent halves of different stigmas aro united, and thus stand op- 

 posite to the placentae. 



1. DROSERA, L. SUNDEW. (Gr. dpooog, dew ; from tlio dew-like 

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

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

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

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

 tion circinate. 



Scapes 4 6 times as long as the leaves Nos. 1 3 



Scapes 1 2 times as long as the leaves Nos. 4 6 



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

 fls. white. A curious little plant, not 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, tho racemes uncoiling as tho small whito flowers 

 open. Caps, oblong. Jn. Aug. 



2 D. minor. Los. obovate, cuneiform at lose, the petioles naked; fls. purple; scapo 

 erect. Aforo delicate than the 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 is 23" wide. Scapes filiform, 36' high, tho raceme simplo 

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

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

 Chapman.) 



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

 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, 12 ^ 

 broad, flat on the ground, forming a round, compact rosette. Scape 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 

 lose 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 23'. Candex lengthened, declinate. Scape bearing a simple racera 

 of small, whito flowers, arising 4 7'.. Jn. Aug.
