Of the Urticaccac, the Mamake (Pipturns albidus) , Maoloa 

 (Neraudia uiclastomacfolia), and Wauke (Brousonettia papy- 

 rifera) are here represented. The Wauke, which w&s used by 

 the natives for making their tapa, or paper cloth, was extensively 

 cultivated in former days. It is only found at the settlement of 

 Puuanahulu in the midst of a Cactus hedge. 



A few adaptive characteristics of the plant covering of this 

 hot and dry district may be mentioned before this paragraph is 

 dismissed. The prevailing type of wood is of a hard, close- 

 grained texture, such as that of Mezoneurum Kauaiense, Colu- 

 brina oppositifolia, and Acacia Koaia, the latter being found 

 on the dry slopes of Puuanahulu ; also Maba sandwicensis, Plec- 

 tronla odorata, Sophora crysophylla, and others. 



It appears that in this dry, rocky region the tendency for trees 

 and shrubs of slow growth is to form harder and finer wood 

 than those of rapid growth. 



PUUWAAWAA. 



The greatest variety of trees and shrubs is found on the little 

 hill called Puuwaawaa, and in its vicinity. This 300-foot hill, 

 rising at an elevation of 2700 feet, is like an oasis in a desert, 

 the like of which can be found in the upper regions of Hualalai. 

 Rough a-a surrounds its base, while on its slopes luxurious 

 vegetation grows in the rich, dark soil, bearing some resemblance 

 to the plant covering of Waihou and the middle forest belt of 

 Mt. Hualalai. 



The Olopua, or Pua (Olea sandwicensis), a handsome tree, 

 is found on its lower slopes near the edge of the lava fields in 

 company with a Sapindus, an apparently underscribed species. 

 Charpcnticra ovata and Pisonia incrmis, both very soft wooded 

 trees, called Papala by the natives, can be found here in company 

 with representatives of the order Rutaccae. 



Pittosporutn Hosiucri, a species new to science, (see plate 20 

 and description in part), called Aawa hua kukui by the natives, 

 on account of the large fruits resembling the Kukui nuts, is a 

 common tree in this region. It is astonishing that a tree as com- 

 mon as the above mentioned Pittosporum should have been over- 

 looked. It can only be assumed that the region in question had 

 never been visited by any collector or botanist. 



The mature fruits of said Pittosporum are of enormous size 

 with woody capsule of 3^x2^2 inches. 



HUALALAI. 



On June 8, preparations were made for the ascent of Hualalai, 

 where camp was established at Kalulu, an elevation of 6000 feet.
