310 SCROPHULARIACE^. Pedlcularls. 



) -I H ( H Galea completely straight and anteriorly rectilinear, edentulate, very much 

 longer and larger than the depauperate lip, slightly broader upwards; the whole corolla therefore 

 more or less clavate. 



P. den.sifl.6ra, Benth. Pubescent or glabrate : stem stout, 6 to 20 inches high, leafy : 

 leaves ample (-4 to 12 inches long), of oblong outline, twice pinnatifid or pinnately parted, 

 and the lobes laciniate-dentate ; the irregular salient teetli cuspidate-tipped : spike at first 

 very dense, oblong (2 or 3 inches long), in age looser and longer (sometimes a foot or more 

 long) ; lower bracts leaf-like ; uppermost almost entire and equalling or shorter than the 

 short-pedicellate or sessile flowers: calyx deeply 5-toothed; the teeth lanceolate or subu- 

 late: corolla scarlet-red, fully an inch long; lip a line or two long: filaments glabrous.

 DC. 1. c. Dry hills, almost throughout California, at least in the western part of the State. 

 A variable but most distinct species. 



37. BHINANTHUS, L. YELLOW-RATTLE. (Formed of QIP, snout, and 

 dvdog, flower, now meaningless, for the species with beak to the upper lip of the 

 corolla have been removed to another genus.) Comprises a very few annuals of 

 northern temperate zone ; with erect stem, opposite leaves, and mostly yellow 

 subsessile flowers in the axils, the upper ones crowded and secund in a leafy- 

 bracted spike ; in summer. Seeds when ripe rattle in the inflated dry calyx, 

 whence the popular name. 



R. Crista-galli, L. About a foot high, glabrous, or slightly pubescent above: leaves 

 from narrowly oblong to lanceolate, coarsely serrate ; bracts more incised and the acumi- 

 nate teetli setaceous-tipped : corolla barely half inch long, only the tip exserted ; trans- 

 verse appendages of the galea transversely ovate, as broad or broader than long : seeds 

 conspicuously winged. Spec. ii. 603, mainly ; Engl. Bot. t. 657. R. minor, Ehrh. Beitr. vi. 

 144. Coast of New England, rare, and perhaps introduced. Alpine region of the White 

 Mountains, New Hampshire, Labrador and Newfoundland, Lake Superior, Rocky Moun- 

 tains, extending south to New Mexico, and north-west to Alaska and Unalaska ; clearly 

 indigenous. (Greenland, Eu., Asia.) Varies much in size, but apparently we have no 

 R. major, Ehrh. 



38. MELAMPYTIUM, Tourn. COW-WHEAT. (The name, f rom ji&off and 

 nvQOg, means black wheat : in Europe some species are weeds in grain fields.) 

 Low and branching annuals ; with opposite leaves ; chiefly European, one Atlantic 

 N. American : fl. summer. 



M. Americanum, Michx. Nearly glabrous, a foot or so high, loosely branched : 

 leaves lanceolate or linear-lanceolate, short-petioled ; lower entire ; upper with abrupt base 

 and one or two bristly-acuminate teeth, or nearly hastate : calyx-teeth longer than the tube, 

 subulate-filiform, one-third the length of the slender pale yellow (barely half inch) corolla : 

 flowers scattered in the axils of ordinary leaves. Fl. ii. 16; Gray, Man. 338. M. lineare,

ORDER XCVII. OROBANCHACE.E. 



Root-parasitic herbs, destitute of green foliage (whitish, yellowish, reddish or 

 brown), with alternate scales in place of leaves, the two (single .or double) multi- 

 ovulate placentae parietal, and ovary consequently one-celled, the very small and 

 innumerable seeds with a minute embryo having no obvious distinction of parts, 

 otherwise nearly as Scrophulariacece. Flowers hermaphrodite, 5-merous as to
