hollow and a little thickened upwards below the heads in fr. 
Heads umbilicate hemispherical in fr. ; scales all adpressed un- 
equal broad obtuse, the outer ovate or oval keeled fleshy pale 
glaucescent gr. with narrow scarious pale drab-brown edges, 
inner very broadly oblong or spathulate broadly scarious and 
undulate at top. Disk of fi. golden-y. ; ligules either (as more 
commonly in PS.) pale straw or ochre-y. deeper or golden-y. 
at the base, or, as in FI. Gr. and RFG. 1. c. and mostly in Mad., 
uniform deep full golden-y. like the disk, about 6 lines long, 
2 wide, their length equalling diam. of disk. Recept. naked 
in all stages, convex, in fr. subhemisplierical but twice as 
broad as high, spongy- or pithy-solid within. Ach. chestnut 
brown, the spaces between the ribs concave or depressed gra- 
nulato-rugulose and sprinkled with shining resinous dots ; of 
ray largest, 2-3 millim. long and broad, subequally 3-sided, 
the 2 dorsal angles sharp and narrowly winged, each wing 
ending at top in a small tooth or denticle, inner angle broadly 
winged, especially upwards, where it ends in a large laterally 
or horizontally prominent compressed tooth or angle; back 
plano-convex with a single smooth broad flat rib up the mid- 
dle, the sides concave with mostly 2 or 3 narrow fainter ribs, 
the whole surface being finely retieulato-granulate and sprinkled 
with resinous dots. Ach. of disk smaller more distinctly gra- 
nulate and copiously resinoso-punctate, mostly nearly or quite as 
broad as long, much compressed 2-sided with the inner angle 
only sharply winged and distinctly beaked or toothed at top, 
the back bluntly keeled with a prominent but not winged 
dorsal rib and the sides each very strongly 2- or 3-ribbed. A 
few smaller ach. also occur occasionally less compressed and 
irregularly 4-5-gonal. All the ach. are abruptly truncate at 
top without any erect tooth or denticle and with no trace of 
crown or border ; and their form is that of the inverted frus- 
tum of a cone, 3-sided in the ray, compressed or 2-sided in the 
disk. 
I can find in my spec, no warrant for the application of the 
words u apice dilatatis ” DC. or u Margis vers le sommet ” Gr. 
et Godr. to the lobes or segments of the 1. But it is true of 
the whole 1. as originally laid down by Linnaeus.
