late, 114 x 34 in. subterminal. Ramulars inconspicuous, oval- 
acute. 
Leaves light green, firm, mostly smooth and but slightly thick- 
ened, but the lower ones much thickened and roughened, especially 
when in unusual sun; the leaves and whole plant glabrate or 
almost without minute hair even on the pedicels. 
Petioles chiefly long and slender, the lower cauline and radical 
petioles not so long as the leaves, however; each base enlarged 
into a small close-clasping dilation extending two-thirds around 
the stem. 
Veins of highly pinnate aspect, about 6 pairs, strongly out- 
curved, followed by several shorter upcurved pairs, darker than 
the leaf above, beneath paler and only very slightly projecting. 
Inflorescence deep-branched and at an acute angle, a leafy 
corymb sometimes 12 in. high and 8 in. broad, centrally flattish, 
the lower branches much pieni in developing and not reaching the 
uniform level. Heads about 4. to 4*. in. hi 
Bracts rigid, pale or eR their green tips not very strongly 
developed, their straight parallel sides suddenly terminating in a 
short or bevelled acutish apex.
