310 SCROPHULARIACE.E. Pediculurk. 



-f— H 1 1— -)— Galea completely straight and anteriorly rectilinear, edentulate, very inuch 



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

 more or less clavate. 



P. densiflora, 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 teeth 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. 

 — Hook. Fl. ii. 110, & DC. I.e. 574; Gray, Bot. Calif, i. 583. P. aUennata, Benth. in 

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

 A variable but most distinct species. 



37. RHINANTHUS, L. Ykllow-rattle. (Formed of (nv, 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 teeth 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. 057. 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. MELAMP"^RUM, Tourn. Cow- Wheat. (The name, from jwArts^ and 

 nvQO^, 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. Americantim, Michx. Nearly glabrous, a foot or so high, loosely branched : 

 leaves lanceolate or linear-lanceolate, short-petioled ; lower entire; upi)er 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. Unenrc,

Order XCVII. OROBANCHACEJE. 



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 w'ith a minute embryo having no obvious distinction of parts, 

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