AND GENERA OF PLANTS. 423 



POLYACHYRUS. (Lagasca.) 



Pohjachyrus * ghnduhsus; 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; capituli two- 

 flowered. 



Hab. 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.
