272 63. PLANTAGINACE^. 



doubled inwards. Ovary free, of 1 carpel, 1 -celled, or with a cen- 

 tral compressed 2 — 4-winged placenta and thus 2 — 4-celled. 

 Ovules 1 or 2. Style 1. Caps, opening transversely. Seeds pel- 

 tate or erect. Radicle inferior. — G. F. G. Gam. i. 1 and 2. 



1. Plantago. F1. perfect. Cal. 4-cleft. Cor. with an 

 ovate tube and 4-parted reflexed limb. Stam. on the corolla. 

 Caps, bursting transversely, 2 — 4-celled, 2 — 4-seeded. 



2. LiTTORBLLA. Moncecious. Male fl. stalked; sep. 4; tube 

 of the cor. cylindrical, limb 4-parted ; stam. hypogynous ; 

 filaments very long. Fem. fl. sessile ; sep. 3; cor. oblong, 

 narrowed at both ends; style long; caps. 1 -seeded. 



1. Plantago Linn. Plantain. 



* Placenta 3 — 4-winged, thus forming 3 — 4 cells. Seeds I in 

 each cell. 



1. P. Coronopus (L.); 1. linear pinnatifid or dentate, scape 

 round, spike slender, bracts subulate from an ovate base erect, 

 midrib of lateral sep. with a ciliated membranous wing. — £.5.892. 

 — Tube of the cor. glabrous.' Extremely variable in size and 

 amount of pubescence, woolly or nearly glabrous. L. varying in 

 width, nearly entire, or even doubly pinnatifid. Spikes slender, 

 I5 in. long, many-fiowered ; or spherical with 2 — 6 fiowers. — 

 Gravelly barren spots near the sea and inland. A. ? VI. VII. 

 Buck's-horn Plantain. 



** Placenta 2-winged. Seeds 1 in each cell. Cor.-tube 

 pubescent. 



2. P. maritima (L.) ; 1. linear channeled fleshy convex on 

 the back, scape round, spike cylindrical, bracts ovate mueronate, 

 Sep. not winged. — E. B. 175. St. 88. 4. — L. usually woolly at 

 their base, nearly flat and broad or linear, toothed or quite entire, 

 glabrous or hairy ; 3-veined, veins equidistant. Scape glabrous 

 or hau-y. Caps, oblong-conical. Very variable in size. In a 

 Cornish variety the 1. are only 1 — 2 lines in length and semi- 

 cylindrical, scapes very short, spikes sometimes only 3- or 4- 

 flowered. — The mountain plant is apparently P. serpentina (Vill.); 

 its caps, is ovoid and blunt, bracts lanceolate acute perhaps not 

 keeled, 1. not channeled. It is probably a distinct species. — Sea- 

 coast and on mountains. P. VI. — IX. 



*** Placenta 2-winged. Seeds 1 in each cell. Cor.-tube 

 glabrous. 



3. P. lanceolata (L.) ; I. lanceolate attenuated at both ends 

 6-veiued, scape furrowed, spike ovate or oblong-cylindrical.
