PISONIA L. Sp. PI. 1026. 1753. 



. Pisonia sandwicensis Hillebr. Fl. Haw. Is. 369. 1888. 



Staminate specimens were collected at the second fall of the 

 Wahiawa river, Kauai, which is at an elevation of about 2000 

 feet. Pistillate ones were obtained at the base of the plateau 

 above Waimea, at about 3000 feet elevation. This species is a 

 good sized tree, often twenty-live feet or more in height, with 

 a trunk diameter of eight or ten inches. The male flowers are 

 pinkish in color, and sweet scented. The white or pink tinged 

 perigone, and long- exser ted stamens, present a very attract- 

 ive appearance. The female flowers are much smaller, and 

 greenish. 



July to September (2598, 2784). The range is given from 

 Maui to Kauai, but it has not been reported from Oahu. 



Pisonia umbel life ra (Porst.) Seem. Bonplaudia 10:154. 1862. 

 Ceodes umbellifera Forst. Char. Gen. 71, pi. 71. 1776. 



Specimens referable to this species were collected on Kauai, 

 on the ridge west of the Hanapepe river, and on the ridge be- 

 tween the Hanapepe and Wahiawa rivers, at elevations of about 

 2000 feet. The fruit of these specimens was not at all viscid, 

 and did not stick to the paper. But on Oahu, on the edge of 

 the plateau above Manoa, specimens were seen, the fruit of 

 which was very viscid, sticking tenaciously to anything with 

 which it came in contact. Hillebrand says: "'The fruiting 

 perigone of all three species exudes a very viscid glue. * * * 

 It will stick fast to paper in the herbarium for years." 



June to October (2453); original locality, island of Tanna, 

 New Zealand.
