-LXXXIX. AMPHIGLOSSA, DC. (reform.) 
Heads 6-20-f1., heterogamous, radiate ; ray-fl. ligulate, sometimes very 
minute and shorter than the involucre; dise-fl. perfect, 5-toothed. Re- 
cept. naked. Invol. cylindrical, imbricate, scarious. Achene glabrous. 
Pappus of many very slender, deciduous, separate bristles, closely and 
amply feathered through their whole length, with or without a minute,

Small, much branched, erect or decumbent shrublets. Leaves small, linear or 
subulate, glabrous and convex externally, woolly within, with inflexed or involute 
Heads solitary, terminal, sessile. Name from ayqui, both, and yAwsoa, & 
tongue; alluding to the ray-fl. being different in the two sections of this genus. It 
differs from Pterothrix merely in having heterogamous fl. heads.

1. A. corrudefolia (DC.! 1. c. 258) ; diffuse or trailing, branched and 
ramulous; rameal leaves broadly subulate, mucronate, keeled, with in- 
flexed margins, spreading, the axils with leaf-tufts; twig-leaves short, 
spreading, mucronate ; heads 6-8-fl., heterogamous, on very short, axil- 
lary branchlets ; ray-fl. 2-3, very slender, with very minute, included 
ligules ; inner inv. scales linear, obtuse.

Stems several inches long, woody, glabrate, apparently trailing ; but DC. says 
** erect.” Rameal leaves 4~6 lines long, 1 line wide ; those on the twigs much shorter. 
Heads 3-4 lines long. 
2. A. callunoides (DC.! 1 c. 259); diffuse or trailing, the long, sim- 
ple branches closely ramulous; rameal leaves broadly-subulate, mucro- 
nate, keeled, with inflexed margins, the axils ramuliferous; twig-leaves 
very small, close-pressed, oval-oblong or linear, obtuse or mucronulate ; 
heads 10-12-fl., heterogamous, on short, axillary twigs; ray-fl. 5-6, 
with narrow, linear, 3-toothed, purple, sub-exserted ligules ; inner inv-

- Very near the former in character, but with a different aspect, and much more ~ 
evidently ligulate ray-flowers. Twig leaves shorter and more imbricating. 
3. A. tomentosa (Harv.); divaricately much branched, spreading, 
slender; leaves linear-trigonous, mucronate, spreading, often with leaf- 
tufts ; heads terminal, 9-10-fl., heterogamous ; ray-fl. about 3, with 
strapshaped, revolute, exserted ligules, longer than the disc ; outer inv- 
scales ovate, inner linear-oblong, acute, rufous, glossy. A. nitidula, DC.!
