Pungo ANDONGO.—A perennial herb, with a habit slightly Car- 
duacous ; stems slender, simple and one-headed or branched from the 
middle and several-headed; capitula homogamous, many-flowered, 
bright purple throughout except the anthers ; involucre campanulate ; 
the scales imbricate, pluriseriate, broadly lanceolate and crowded at 
the base, from the middle towards the apex lanceolate and rather 
lax, the outer ones shorter, mostly much acuminate, the inner ones 
elongated, liguliform, rather obtuse, spinulose-denticulate especially 
towards the apex; florets all tubular, blood-red ; the corolla glabrous, 
pentagonal at the bottom, then abruptly contracted into the filiform 
tube and at the top abruptly again dilated into the shorter widely 
campanulate 5-cleft limb ; the lobes shorter than the tube, reflexed, 
triangular lanceolate ; anthers exserted, rather rigid, loosely cohering, 
appendaged at the apex each with an erect oblong-globose stipitate 
gland, caudate at the base ; the tails fimbriate-lacerate at the tip, pilose, 
empty, pellucid, nearly flat, broadly linear ; filaments naked, inserted 
in the bottom of the corolla-throat, nearly flat; pollen spherical, 
tolerably large, coarsely echinate ; ovary somewhat compressed, sub- 
pentagonal or rarely hexagonal, oblong, narrowed-subtruncate at 
both ends, pilose especially on the angles, surmounted by 5 or rarely 
6 compressed unequal narrowly linear-lanceolate much acuminate 
deciduous palez which are pilose-serrulate on the margin and more or 
less as long as the corolla-tube ; style red, strong, glabrous; its 
branches semi-cylindrical, flat inside, with a semicircular ring of hairs 
below the apex ; achene glabrate or pubescent, much larger than the 
ovary, very hard, ovoid-oblong, obtusely 5- or 6-angled, brown, truncate 
at the apex surmounted by the small cyathiform 5-crenate nectary ; 
the angles thick, obtuse, more prominent near the base, gibbous- 
protruded at the apex; pappus obsolete ; receptacle paleaceous, the 
palez: more or less similar to the involucral scales, nearly flat, strongly
