A very handsome tree with large cream-colored flowers; it reaches a height of 
about 25 feet and has stiff ascending branches. Hillebrand’s description, which 
has been enlarged upon to suit the abundant material which is at the writer’s 
disposal, agrees exactly with plants from the type locality. It is not uncommon 
on West Maui, above Kaanapali, at an elevation of about 3500 to 4000 feet, 
where it grows in the rain forest. It was also collected by the writer in Iao 
Valley, on the same island. 
On East Maui, in the rain forest of Mt. Haleakala, at an elevation of 4009 
feet, the writer met with a Pittosporum which he must refer to this species, 
though differing somewhat from the trees found on West Maui. This is, how- 
ever, not surprising, since all Hawaiian Pittosporums are very variable. The 
East Maui plants differ from the West Maui ones in the inflorescence, which ~ 
shorter peduneled and has almost sessile flowers: the latter agree, however, with 
those from the type locality. On the northern slope of Haleakala, at Nahiku, 
on the crater Hinai, at an elevation of about 3000 feet, the writer met with a 
large number of trees which will also have to be referred to this species; they 
differ from the type specimens in the young leaves, which are covered with light 
brown tomentum, and in some other minor points. 
On the same mountain, at 2000 feet elevation, the writer collected Hillebrand’s 
var. & of this species, which is easily distinguished by the long axillary pe- 
duneles, which measure often 5 em. and more. The variety is a small tree, 15 to 
18 feet in height.
