Apr., M ay. — A small insignificant weed, branched on all sides 
from the crown of the slender sparingly divided root and form- 
ing flat close-pressed regular dense patches from 2-6 in. in diam. 
of a peculiar pale apple or light y.-gr. and elegant pattern-like 
appearance, owing to the fan-like regularity with which the 
secondary or side-branchlets spread distichously and at equal 
distances and angles in the same plane on each side of the main 
branches, and become gradually shorter towards the ends of the 
latter, like the branches of a well-trained fruit-tr. on a wall en 
espalier. Root wiry tortuose or flexuose hard and somewhat 
tough but scarcely woody and decidedly ann., pale or whitish, 
scarcely or sparingly branched. Branches completely prostrate 
quite to their ends round hard stiff wiry straight or very faintly 
flexuose often red or purple, clothed with very short fine close- 
set horizontally spreading straight furry or velvety pubescence 
unmixed with bristles. L. small inconspicuous or overrun by 
the fr. -clusters, 2-4 or 5 lines long, f-l| line broad, mostly 
naked, the lower sometimes more or less furry or velvety, but 
all sprinkled all over on one or both sides with spreading bris- 
tles and distinctly c-iliate at the edges. FI. minute gr. incon- 
spicuous ; sep. in fr. connivent shortly furry or velvety-pubes- 
cent and equably eehinulate-setose or hirsute all over and not 
particularly at their tips or edges with stiff w. bristles spreading 
all round, their tips not distinctly aristate or bristle-pointed. 
Fr. rather large i. e. 1| millim. long narrow-ovate or elliptic 
compressed, thickly furry and equably echinato-hirsute or setose 
all over with longer straight w. bristles spreading on all sides 
and as long as the diam. or even axis of the fr., which beam a 
sort of miniature resemblance to that of Xanthium or Ricimis. 
Scarcely perhaps distinct from II. cinerea DC., but the st. 
are wholly prostrate or flatly adpressed all their length to the 
ground, not ascending or with the ends upright, and there is no 
trace of a persistent woody rootstock or perenn. root. As to 
this last particular however, there is a discrepancy in authors : 
DC. e. g. calling the root in II. cinerea ann., Gren. and Godr. 
per. Still, in the absence of positive proof of identity from 
comparison with authentic spec., it is better to retain the Mad. 
pi. distinct provisionally. 
It differs from II. hirsuta L. in being much more hairy or
