present, dull subglaucous-green, more or less hairy on both sur- 

 faces; petioles channelled above, shallowly ridged on the back, 

 dilated, sheathing and crimson at the base, subscabrously hairy. 



Anacyclus radiatus, Lois. 



Hypocotyl erect, terete, glabrous, 3-4 cm. long, light green tinged 

 with red. 



Cotyledons oblong- spathulate, obtuse, entire, tapering to the 

 base but scarcely petiolate, connate at the base, fleshy, glabrous, 

 light green, indistinctly pinnatinerved. 



Stem herbaceous ; primary internodes undeveloped. 



First leaves pinnatifid, cauline, alternate, with a few hairs, 

 tapering to the base, pinnatinerved ; lobes acute, entire or bifid, 

 light green. 



Gonospermum fruticosum, Less. 



Hypocotyl erect, terete, covered with very minute hairs, 3-5- 

 S'75 cm. long, brownish. 



Cotyledons very long, linear-lanceolate, subacute, entire, tapering 

 to the base, glabrous, green, trinerved, sessile. 



Stem erect, terete, herbaceous, ultimately shrubby ; 1st internode 

 2-3 mm. long ; 2nd and 3rd about the same. 



First leaf simple, ovate-oblong or almost lanceolate, acute, 

 coarsely serrate, covered with minute hairs, green, pinnatinerved ; 

 leaves after the first one alternate, pinnatisect ; terminal segment 

 similar to the first leaf; lateral segments small, serrate, oblong, 

 acute ; petioles short, thick, deeply channelled on the upper face. 



Lonas inodora, Gaertn. 



Seed narrowly obovoid, subcompressed, readily removable when 

 fresh from the achene to the interior of which it conforms. 



Embryo conforming to the seed which it wholly occupies ; coty- 

 ledons plano-convex, obtuse, entire, closely occupying the interior 

 of the upper and broader end of the seed, and applied face to face ; 

 radicle tapering to an obtuse point and occupying the narrow end of 

 the seed, nearly equalling the cotyledons in length but much narrower ; 

 plumule minute and scarcely, if at all, discernible. 



Seedling (fig. 469). 



Primary root tapering downwards, giving off slender lateral 

 rootlets, colourless, flexuose, annual. 



Hypocotyl erect, terete, stout, tapering into the radicle, pale green, 

 glabrous, 3'5-5'5 mm. long.
