26. ODONTITES [Rivinius] Ludwig. 



Calyx equally cleft. Corolla with upper lip entire and sides not folded back. 

 Otherwise much as Euphrasia. Herbs, with opposite sessile leaves, and sub- 

 sessile flowers in the upper axils and in a terminal leafy spike. (Odontitis, an 

 ancient plant-name from 65ovs, tooth, applied to some herb used for tooth-ache.) 



1. 0. RtiBRA Gilib. Stem 1-4 dm. high, from an annual root, branching, 

 scabrous-pubescent ; leaves oblong-lanceolate, coarsely and remotely serrate ; 

 spikes elongated, loosely-flowered ; corolla small, rose-red. (Bartsia Odontites 

 Huds.; Odontites Odontites Wettst.) Fields, roadsides, etc., coast of Me., 

 N. B., and N. S.; rarely in the interior. (Nat. from Eu.) 



27. PEDICULARIS [Tourn.] L. LOUSEWORT 



Calyx various. Corolla strongly 2-lipped ; the upper lip flattened, often 

 beaked at the apex ; the lower erect at base, 2-crested above, 3-lobed ; lobes 

 commonly spreading, the lateral ones rounded and larger. Anthers transverse ; 

 the cells pointless. Capsule mostly oblique, several-seeded. Perennial herbs, 

 with chiefly pinnatifid leaves (the floral bract-like) and rather large flowers in a 

 spike. (Name f rom pediculus, a louse ; of no obvious application.) 



* Small-leaved annual or biennial, mostly branched, bearing axillary and termi- 



nal flowers. 



1. P. palustris L. Essentially glabrous, 2-6 dm. high ; leaves lanceolate, 

 2-6 cm. long, pinnately parted, with small crenate oblong segments ; calyx-lobes 

 cristate ; corolla 1-1.5 cm. long, purplish and rose-color (rarely white), the tube 

 longer than the lips. ( P. parviflora Britton, not Sin. ) Marshes and wet places, 

 Temiscouata Co. to Gaspe Co., Que., Nfd., and north w. (Eu.) 



* * Large-leaved perennials ; simple or somewhat branched, with terminal spikes. 



2. P. canadensis L. (COMMON L., WOOD BETONY.) Hairy ; stems simple, 

 clustered, 1.5-4 dm. high ; leaves scattered, the lowest pinnately partoL tin- 

 others half-pinnatifld ; spike short and dense ; calyx split in front, otherwise al- 

 most entire, oblique ; upper lip of the dull greenish-yellow and crimson cnmUa 

 Jmuili'd, incurved, 2-toothed under the apex; capsule flat, somewhat sword- 

 shaped. Copses and banks, N. S., centr. Me., and w. Que. to Man., and south w. 

 May, June. 



3. P. lanceolata Michx. Stem upright, 3-9 dm. high, nearly simple, mostly 

 smooth ; leaves partly opposite, oblong-lanceolate, doubly cut-toothed; spike 

 crowded ; calyx "2,-lobed, leafy-crested ; upper lip of the pale yellow corolla in- 

 curved and bearing a short truncate beak at the apex, the lower erect, so as 

 nearly to close the throat; capxulr. ortitc, scarcely longer than the calyx. 

 Swamps, Mass, to Ont. and Man., s. to Va., O., and Neb. Aug., Sept. 



4. P. Furbishiae Wats. Tall (5-9 dm. high), pubescent or glabrate ; Ifnrrs 

 lanceolate, pinnntfly parted and the xJmrt oblong divisions pinnatifld-inciscd, 

 or the upper simply pinnatifid and the lobes serrate, silvery-margined ; bracts 

 ovate, laciniate-dentate ; calyx 5-lobed, the lobes rather unequal, linear-lanceo- 

 late, entire or toothed ; upper lip of corolla straight and beakless, the truncate 

 apex bicuspidate, the lower erect, truncately 3-lobed ; capsule broadly ovate.

28. RHINANTHUS L. YELLOW RATTLE 



Calyx membranaceous, flattened, much inflated in fruit, 4-toothed. Upper 

 lip of corolla arched, ovate, obtuse, flattened, entire at the summit, but with a

 mate, hairy, transverse : the cells pointless. ( 'apsule orbicular, flattened. Seeds 

 orbicular, winded.- Annual upright herbs, with opposite leaves; the yellow or 

 yellowish flowers crowded in a one-sided leafy-bracted spike. (Name composed
