The Alaa is a fine tree of often 50 feet in height and is conspicuous in the 
forest by its leaves, which are of bronze to reddish brown color underneath, due 
to a hairiness of that color. It is usually found in the dry districts of nearly all 
the islands, and is especially common on Lanai in the valleys of Kaiholena and 
Mahana. On Maui big trees can be found above Makawao, in the gulches of the 
north-western slopes of Mt. Haleakala, as well as at Auahi, on the south side of 
‘the said mountain. On Hawaii this species is wanting, but the genus is repre- 
sented by another species, S. awahiense var. aurantium Rock, with globose orange 
colored sessile fruits. The natives employed the milky sap as a bird glue. Hille- 
brand remarks in his Flora that the fruit of this tree is rarely met with perhaps 
on account of dimorphism in the flower. This the writer cannot verify, as al 
the trees found by him bore fruit in abundance, with the exception of on Kauai, 
where none of the trees bore perfect fruits, but were all abortive and conse- 
quently of very small size. The fruits are not always globose, but are quite often 
Ovate, obovate and even long pear-shaped and of a black eolor. It inhabits 
mainly the dry districts, but can also be found along the Manoa Valley trail and 
Tantalus on Oahu, as well as at Kahuku, Waialua, and the Waianae range. 
Hillebrand records a variety 8. auratum with leaves and calyx, as well as co- 
rolla, densely ferruginous. The flowers are also generally single. Collected by 
Hillebrand on the dry forehills of Molokai and Lanai. From the latter islands 
the writer collected material which he must refer to this variety, though the 
flowers are not always single but often two in each leaf axil. Rock, Lanai, Kai-
