The Aalii kumakani is a small phair or tall, much-branched shrub or medium- 
sized tree of 20 feet or so in height. It differs very little from the Aalii kuma- 
kua, and that mainly in the pubescent capsules, which are three or four- 
winged, instead of having two wings. It is a shrub on the leeward side of Kauai, 
above Waimea on the open, barren slopes at an elevation of 2000 feet, and is a 
small tree on the upper slopes of Mt. Haleakala at elevations of 6000 to 8000 
feet, where it grows in gulehes and along dry stream beds in company with a 
species of Suttonia, with the Silversword, Argyroxiphium sandwicense var. 
macrocephalum, A. virescens, the green sword plant, and numerous other Com- 
positae, as Raillardia, and Artemisia. It is a handsome tree with dark-green, 
viscous, shining leaves, forming a beautiful, symmetrical, round crown. It alse 
occurs on Hawaii in the dry regions of Kau, and on the central plateau on the 
slopes of Mauna Loa. 
On Molokai above Kamalo grows another species (Dodonaea stenoptera Hbd.) 
peculiar to the above locality. It is, however, never a tree and therefore here 
omitted. 
i RHAMNACEAE. 
The family Rhamnaceae occurs in all regions whose climate permits lignaceous 
growth. The genus Rhamnus is the widest distributed; its center of develop- 
ment is Europe and extra tropical Asia. Here in the Hawaiian Islands the 
family, with its 45 genera, has only two representatives, the genera Alphitonia 
and Colubrina, with only one endemic species belonging to the latter genus.
