also found as a small tree 15 to 18 feet in height on the floor of Haleakala crater 
in Koolau gap and Kaupo gap, in company with Sophora chrysophylla (Mamani), 
Geranium tridens (Hinahina), and the well-known Silversword (Argyroriphiuwm 
sandwicense var. macrocephalum). 
It has been reported by Hillebrand to grow only at very high elevations near the 
summit of the mountain, together with Raillardia and Geranium. It may, how- 
ever, be of interest to state that it was observed by the writer on the southern 
slopes of Haleakala on the lava flows of Auahi, Kahikinui, at an elevation of 2600 
feet. At this latter locality, which is one of the richest botanical districts in the 
Territory, it is a fine-looking tree and does not show any signs of stiff branches 
and short, gnarled trunks, as, of course, must be expected at high altitudes. Were 
it not for the dense inflorescence and bright scarlet perigones, one could easily 
mistake it for Santalum ellipticum of Oahu, which it, in reality, resembles greatly. 
The wood of trees from the high levels is exceedingly fragrant, and of a dark 
yellowish brown color. 
AMARANTACEAE. 
The family Amarantaceae occurs in all floral regions of the world, with the ex- 
ception of the frigid zones. It consists of about 40 genera, with about 655 species. 
In the Hawaiian Islands only five genera are represented, two of which are 
endemic (Charpentiera and Nototrichium) and have arborescent species.

The genus Charpentiera is peculiar to the Hawaiian ee and consists of two 
species, Ch. elliptica (Hbd.) Heller, and Ch. obovata Gaud. The former is a 
shrub peculiar to Kauai, the latter a tree found on all the islands. The native 
name of the species is Papala.
