Ncxc Hawaiian Plants. 39 



niuch more pul^esceiit than tliose of A. virescens Hbd, and also 

 differed in the glandular i)ubescent, not silvery raceme. The Pun 

 Kukui plants probably belong to this form. This plant was not 

 observed in any of the extensive bogs on Haleakala, and is probably 

 not a cross between A. macrocephalum and A. virescens or Wilkesia 

 Grayana. Argyroxiphium plants growing- in the bogs on 1 Taleakala 

 are not depauperate. 



A detailed description of Arg'yroxiphium caligini follows : 

 Herb with a stem of 2-2.5 cm. in diameter, soon tapering into a simple 

 foliose raceme of 3-4 dm. in length. Leav-es linear, 10.5- 12.2 cm. long, 

 4-5 mm. wide, densely silvery-sericeous. Raceme simple; the rachis, leaves, 

 and foliar bracts silvery-sericeotis ; the pedicels slender, green, viscous- 

 pubescent. 5-9 cm. long. Heads nodding, 1.5-1.7 cm. in diameter. Invocural 

 bracts viscous-pubescent, green, lanceolate, acitminate. Ray flowers few, 

 ligulate, the ligules bihd, 3-4 mm. in length, i mm. or less in width, purplish 

 colored as are the disk flowers. Disk flowers with the limb 4 mm. in length, 

 narrow below and puberulous, widening above and glabrous. Achenes glab- 

 -rous, 5-7 mm. long, the radial ones shorter and ctirved. Pappus of ray 

 flowers reduced to a narrow truncate coronula. Pappus of disk flowers 

 reduced to 5 or 6 corneous, acute, teeth-like paleae which are deciduous from 

 a disk.
