sparingly dentate. Teeth find Lobules mucro- 

 nato-cuspidate, generally reilexcd. Phyll. oviili- 

 lanceolate, acute, Kecept. hemisplierieal. Chaff 

 broad at the base, produced abruptly into a 

 rigid point, exceeding florets. (Seeds with a 

 narrow wing, Koch.) a. 7, 8. Fields, s. Eur. 



17. Cota. "L. bipinuatifid. Rachis some- 

 what dentate. Div. trifid or pinnato-5-fid. 

 Segm. with a short niucro. Recept. hemi- 

 spherical. Chaff oblong, acuminate into a rigid 

 mucro, shorter than the florets. Seeds with- 

 out a wing ending in an acute margin, a. 

 6, 7. Vineyards. 1st. Fiume."- — Koch. 



18. anglica. " Stem prostrate, hoary. L. 

 bipinnatifid, acute, fleshy, dotted on upper sur- 

 face. Outer PhyU. acute ; inner longer, torn, 

 and almost feathery. Recept. convex. Chaff 

 prominent, a. 7. Rocky coast. Sunderland." 

 — Sm. The dots on the L. are not represented 

 in the figure in ' Eng. Bot.' nor does the chaff 

 there appear to he prominent. These dots, 

 and the lanceolate, acute, and not av:ned 

 chaff, seem to distinguish this from both Cota 

 and altissima. The figure also suggests the 

 idea of loinged seed.

 fid. Segm. lineari-lanceolate, entire or with 

 2 or 3 acute, mucronate teeth. Recept. cyliu-

 a short, obliquely truncate crown, a. 7, 8.

 somewhat abruptly contracted to a point, as long
