AND GENERA OF PLANTS. | 423 
POLYACHYRUS. (Lagasca.) 
Polyachyrus * glandulosus; summit of the stem and involucrum glandularly 
pubescent, outer scales acute and much larger than the rest, which are scariose 
and smooth; pappus of the outer flower shorter on one side; leaves 
amplexicaule, the uppermost subulate, glandular and entire; =. two- 
flowered. 
Has. In Peru. (Mr. Curson.) The specimen I possess is only a flowering fragment. The 
lower part of the stem is smooth; the leaves have been deciduous, and being wanting the form is 
unknown. The flowering cluster is three times as large as that of P. niveus (which Mr. Curson 
also collected in Peru,) the two outer scales lanceolate and acute, glandularly scabrous, the inner 
smaller scales are tipped with red; a large chaffy scale intervenes between the two flowers of the 
involucrum. Pappus long and yellowish white, in the outer flower shorter on one side. Ache- 
nium pubescent, more so in the floret, with long pappus. Flowers apparently white. ‘Stigmas 
bearded and truncate at the ‘summit, which is reflected. — Corolla and caudate anthers much as in 
P. niveus.
