 Nat. size. 



petiolate, glabrous, glaucous on both surfaces ; petioles shallowly 

 grooved above, slightly carinate on the back, dilated and clasping 

 at the base. 



No. 1. Cuneate, tripartite ; 

 lateral lobes bifid, terminal trifid ; 

 ultimate segments subulate or 

 narrowly oblong, obtuse. 



No. 2. Tripartite ; lateral lobes 

 cuneate, trifid ; terminal one again 

 trilobed with its middle lobe trifid, 

 the others entire. 



No. 3. Bi-ternatisect ; ultimate 

 segments lanceolate, obtuse, or 

 subacute. 



Nos. 4-6. Bi- to tri-ternatisect ; 

 ultimate segments as in No. 3. 



Ultimate leaves radical, deltoid 

 in outline, tri-ternatisect, with ob- 

 lanceolate or linear-oblanceolate, 

 subacute segments, tipped with 

 orange-red, petiolate ; cauline ex- 

 actly similar or smaller and with shorter petioles. 



Eschseholtzia tenuifolia, Benth. 



Primary root as in preceding, but slender, colourless. 



Hypocotyl slender, erect, terete, glabrous, pale glaucous-green, 

 or colourless towards the base, 6-5-18 mm. long. 



Cotyledons slender, linear, attenuated, obtuse, shallowly grooved 

 above, convex on the back, glabrous, glaucous, slightly broader 

 above the middle representing a lamina, ascending or arching out- 

 wards above the middle, 14-30 mm. long, '5-1 mm. wide. 



Stem short, erect, developed when about to flower, leafy ; primary 

 mternodes undeveloped. 



Leaves cauline, entire at first, ultimately pinnatisect, with a 

 vein running through each segment, but not discernible in the fresh 

 state, shallowly grooved above ; petioles rounded on the back or sub- 

 carinate, grooved above ; otherwise as in preceding species. 



No. 1. Linear, obtuse, slender, entire, or rarely (? accidental) 

 showing a lateral segment, similar to itself but shorter.
