Var. cleistogama. An inch or two liigh, bearing one or two evidently cleistogamous 

 purplish flowers, not larger than a pin's head : capsule becoming a line long. (Gray, JIan. 

 ed. 5, 320; Ell. Sk. i. 24.) — With the ordinary form. Pine barrens of New Jersey, 

 /. A. Paine. Evidently also seen in Georgia by Elliott. 



U. cornuta, Michx. Filiform radical shoots apparently none : leaves fasciculate, evan- 

 escent, rarely at all seen : scape strict, a span to a foot high, 1-10-flowered : pedicels very 

 short, 2-bracteolate at base: corolla an inch long, including the long subulate acute spur; 

 lower lip very large, the sides strongly recurved, and the central palate-like portion as if 

 galeate, merely equalled by the ohovate upper lip : seeds nearly smooth. — Fl. i. 12; Pursh, 

 1. c. ; A. DC. 1. u. U. personata, LeConte, 1. c. ; Bertol. Misc. viii. 21. — Sphagnous or sandy 



^swamps, Newfoundland t o I» S uperior ^nd south to Florida and Texas. (Cuba, Brazil.) 



2. PINGUlCULA, Tourn.^Bu't'fERWoRT. (From pinguis, fat, in allu- 

 sion to the greasy-viscid surface of the leaves.) — Terrestrial acaulescent herbs, of 

 moist or wet ground (in northern hemisphere and the Andes) ; with fibrous roots, 

 broad aiid entire leaves in a rosulate radical tuft, their upper surface with a coat- 

 ing of viscid glands, to which insects, &c., adhere, the margins slowly infolding 

 under irritation ; scapes naked, 1-flowered, circinate-coiled in vernation. Upper 

 lip of the corolla 2- and lower 3-lobed or parted ; the lobes sometimes incised ; 

 the base anteriorly saccate, and the bottom of the sac contracted into a nectari- 

 ferous spur. 



* Corolla distinctly bilabiate, purple, violet, or rarely whitish ; upper lip decidedly smaller, 2-lobed 

 or parted; lower 3-parted ; lobes mo.stly quite entire : boreal species. 



P. villosa, L. Small : leaves oval, nearly glabrous, half inch long or less : scape villous- 

 pubcseent, inch or two long : corolla (pale violet with yellowish-striped throat) 2 lines long, 

 and with a slender spur of nearly the same length or half shorter. — Fl. Lapp. t. 12, fig. 2 ; 

 Fl. D^n. t. 1021; E. Meyer, Labrad. oO; Reichenb. Iconogr. i. t. 82 ; Cham, in Linn, 

 vi. 568. P. acutifolia, Michx. Fl. i. 11, the erect-rosulate oval and very acute leaves described 

 are really the scales of a hybernacular bud, and the plant (with mature fruit) had lost its 

 leaves. — Labrador, Hudson's Bay, Northern islands and shores of the X, W. Coast. 

 (Greenland, Arctic Eu., & Asia.) 



P. alpina, L. Somewhat glabrous : leaves oblong, barely inch long : scape 3 or 4 inches 

 high: corolla (whitish) 4 lines long, and with a conical obtuse divergent incurving spur of 

 less than half the length of the lower lip. — Fl. Lapp. t. 12, fig. 3; Fl. Dan. t. 4.5o; 

 Reichenb. I.e. t. 81 ; Engl. Bot. t. 2747. ^Labrador, Sleinhauer. Given by LeConte to 

 herb. Collins. Specimen not wholly satisfactory, but apparently of this species, not else- 

 where detected in America. ( Eu. to Siberia. ) 



P. vulgaris, L. Jlinutely puberulent or almost glabrous : leaves ovate or oval, an inch 

 or two long, soft-fleshy : scape 1 to 4 inches high : corolla (violet) about half inch long, 

 with campanulate or short-funnelform body abruptly contracted into a narrow Unear- 

 cylindraceous (acutish or obtuse) and raosth' straight spur (of about 2 lines in length). — 

 doder. Fl. Dan. t. 93; Engl. Bot. t. 70; Reichenb. 1. c. t. 84; Hook. Fl. ii. 118; Herder in 

 Radde, iv. 96. P. grandijlora. Hook. 1. c. P. macroceras, Willd. ; Roem. &, Sch. Svst. Mant. 

 i. 168 ; Cham, in Linn. vi. 568 ; A.DC. 1. c. 30 ; a longer-spurred and commonly larger- 

 flowered form (corolla from two-thirds to almost an inch long). P. microceras, Cham. 1. c. 

 (P. macroceras, Reichenb. 1. c. t. 82, fig. 169, 170), a depauperate small-flowered and shorter- 

 spurred form of high northern region. — Wet rocks, Labrador, Northern New England 

 and Nlw York, L. Superior, &c., to Alaskan coast and islands, and northward; the macro- 

 ceras and microceras forms north-westward. (N. E. Asia to Europe and Greenland.) 



* * Corolla light violet, varying occasionally to white, less bilabiate, the sinuses equal except 

 between the two lobes of the upper lip; the three lower lobes usually emarginate or obcordate; 

 palate conical or cultriform, very protuberant, clothed with a dense yellow or sometimes white 

 beard; spur abrupt and nan-ow from base of a short conical sac: upper lip of stigma small, nar- 

 rowly triangular ; lower semi-orbicular : f\. spring. (P. casruUa, Walt. Car. 63, covers one or both 

 the following species, but the character is insutficient to secure the adoption of the name.) 



. P. pumila, Michx. Leaves half to full inch long, oval or ovate: scapes filiform, weak, 

 2 to 6 inches high : corolla a quarter to half inch long ; spvir acute, longer than the rather
