82 DROSERACEJE. (SUNDEW FAMILY.) 



smaller (ty long) elliptical or linear-oblong, often opposite or whorled ; flowers in 

 narrow rather close panicles ; pedicels longer than the oval pods ; the two outer 

 or bract-like sepals very slender, mostly longer than the others. Open dry grounds, 

 N. New Jersey and adjacent part of New York, C. F. Austin. 



4. L. minor, Lam. Minutely hairy; stems slender, upright or diffuse; 

 leafy shoots densely tufted at the base ; leaves linear ; flowers loosely racemed on 

 the slender branchlets ; pedicels mostly longer than the oval pods. Dry open 

 soil : common. June- Sept. Plant 5' -15' high, slender, running into num- 

 berless variations according to the soil, season, and exposure. Pods smaller 

 than in No. 2. 



ORDER 15. DROSERACE^. (SUNDEW FAMILY.) 



Bog-herbs, mostly glandular-haired, with regular hypogy nous flowers, pen- 

 tamerous and withering-persistent, calyx, corolla, and stamens, the anthers 

 flxed by their middle and turned outwards, and a 1-celled pod with twice as 

 many styles or stigmas as there are parietal placentce. Calyx imbricated. 

 Petals convolute. Seeds numerous, anatropous, with a short and minute 

 embryo at the base of the albumen. Leaves circinate in the bud, i. e. 

 rolled up from the apex to the base as in Ferns. (A small family, of no 

 known qualities, except a slight bitterness, &c. ; the Sundews impart a 

 purple stain to paper.) Only one genus within our limits, viz. 



1. DUO SERA, L. SUNDEW. 



Stamens 5. Styles 3, or sometimes 5, deeply 2-parted so that they are taken 

 for 6 or 10, slender, stigmatose above on the inner face. Pod 3- (rarely 5-) 

 valved ; the valves bearing the numerous seeds on their middle for the whole 

 length. Low perennials or biennials ; the leaves clothed with .reddish gland- 

 bearing bristles, in our species all in a tuft at the base ; the naked scape bear- 

 ing the flowers in a 1 -sided raceme-like inflorescence, which nods at the un- 

 developed apex, so that the fresh-blown flower (which opens only in sunshine) 

 is always highest. (The glands of the leaves exude drops of a clear glutinous 

 fluid, glittering like dew-drops, whence the name, from dpo<repos, dewy.) 



1. D. rotundifdlia, L. (ROUND-LEAVED SUNDEW.) Leaves orbicular, 

 abruptly narrowed into the spreading hairy petioles; seeds spindle-shaped, the 

 coat loose and chaff-like ; flowers white, the parts sometimes in sixes. Peat- 

 bogs, common, especially northward. July -Aug. (Eu.) 



2. D. longifdlia, L. Leaves spatulate-oblong, tapering into the long rather 

 erect naked petioles ; seeds oblong, with a rough close coat; flowers white. (D. 

 intermedia, Hayne. ) Bogs ; less common. June - Aug. Plant raised on its 

 prolonged caudex when growing in water. (Eu.) 



3. D. linearis, Goldie. (SLENDER SUNDEW.) Leaves linear, obtuse, the 

 blade (2' - 3' long, scarcely 2" wide) on naked erect petioles about the same length ; 

 seeds oblong, with a smooth and perfectly close coat ; flowers white. Shore 

 of Lake Superior. July.
