 oblongis acutiusculis integerrimis basi truncatis brevi-petiolatis ; pani-

 petalis per antbesin patentibus staminibusque 6 ; stylo longiusculo ; 

 ovario subsemisupero 4-loculari. — Mountains above Waimea, Kauai, at 

 an elevation of 2000 - 3000 feet. — A large, soft-wooded tree, often 

 40 or 50 feet high. Leaves two feet long, leaflets 7 or 8 inches long, 

 2 inches wide. Flowers nearly half an inch across when expanded. 

 Drupe 5 or 6 lines long, pointed with the sulcate style and stigma.

 gis vel ovatis obtusis integerrimis basi cordatis brevissime petiolatis ;

 floris ; stigmatibus 2 sessilibus ; ovario maxima parte supero biloculari 

 (an semper?). — Lanai. — A small tree, 15 or 20 feet high. Leaves 



* Ovarium semisuperum. Folia impari-pinnata. — (Stylus aut longiusculus, aut 

 nullus.) — Uuless genera are founded upon the foliage merely, these two Hawaiian 

 species must apparently be referred to Heptapleurum, Gasrtn. (Paratropia, DC), 

 in which, however, they form a marked section, on account of their pinnate leaves. 

 The summit of the ovary is more or less free in several of the genuine species ; in 

 one of ours the drupe is about one third, in the other even two thirds superior. One 

 of them has a conspicuous style and a 4-lobed stigma; the other two sessile stig- 

 mas, just as Miquel's two sections differ ; and one of them is remarkable for the 

 extreme reduction in the number of the carpels.
