different trees and it is possible that the majority of them may 

 represent a different species, or at least a marked form. They 

 are under No 2456. Later, specimens were collected at the 

 type locality, "on the mountains above Waimea, Kauai." 

 This is No. 2783, and may be considered typical, except that 

 the petioles are slightly shorter than Mann's measurement. It 

 is a beautiful species, with glossy, light green, thick leaves, 

 not " thin chartaceous," as Hillebrand has it. His character 

 of "spathulate" is not so good either, as Mann's original "ob- 

 lanceolatis." The type is M. & B. 603. 



Pittosporum glabrum H. & A. Bot. Beechy, 110. 1832. 



On fruiting specimens, collected in Nuuanu valley, some of 

 the older leaves are rounded, but the younger ones on the 

 same branch are slightly contracted at the apex. None of them 

 are acuminate, nor is there any warrant apparently for Hille- 

 brand's description of " acuminate. " Hooker & Arnott say: 

 "Foliis oblongo-obovatis obtusis basi attenuatis utrinque gla- 

 berrimis supra nitidis." In flowering specimens, collected on 

 the lower slope of Konahuanui, and overlooking Nuuanu. the 

 pedicels are pubescent. With the exception of this pubescence, 

 which apparently soon disappears, the specimens agree very 

 well with the original description of P. glabrum. 



March to May (1985); original locality, Oahu. 



Pittosporum kauaiense Hillebr. PI. Haw. Is. 25. 1888. 



This striking species was collected on the ridge west of the 

 Hanapepe river, Kauai, at an elevation of about 2500 feet. It 

 is a good sized tree, and one of the largest species. The pu- 

 bescence on the under side of the leaves in my specimens is noc- 

 cose, and seems to disappear on the older leaves. The capsules 

 are small, not tuberculate, and covered with short, white to- 

 mentum.
