New Hawatan Plants. 39 
much more pubescent than those of A. virescens Hbd, and also 
differed in the glandular pubescent, not silvery raceme. The Puu 
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 Haleakala 
are not depauperate. 
A detailed description of Argyroxiphium 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. Leaves linear, 10.5-12.2 cm. long, 
4-5 mm. wide, densely silvery-sericeous. Raceme simple; the rachis, leaves, 
and foliar bracts silvery-sericeous; 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, acuminate. Ray flowers few, 
ligulate, the ligules bifid, 3-4 mm. in length, 1 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 curved. 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. 
Type in the B. P. B. M. Herbarium, No. 391, M, collected on Eke, West 
Maui, T. H., October, 1917, by C. N. Forbes. 
Argyroxiphium caligini var Kai var. nov. 
Leaves with a slight greenish hue to the pubescence. Rachis of the 
raceme glandular pubescent and not silvery. 
While of wider distribution than the species, it is much less common. 
The variety is named for Mr. K. Kai, head ditch man at Honokohau Valley, 
Maui, who aided in the exploration of Eke.

West Maui, T. H., October, 1917, by C. N. Forbes. Another specimen in 
the same Herbarium is No. 64, M, collected on Puu kukui, West Maui, T. H., 
May, 1910, by C. N. Forbes.
