154. Heptapleurum (Pterotropia *) Kavaiense (sp. nov.) : 

 arboreum ; foliis impari-pinnatis, junioribus inflorescentiaque dense fur- 

 furaceo-puberulis demura glabratis ; foliolis 15-19 coriaceis elongato- 

 oblongis acutiusculis integeri'imis basi truncatis brevi-petiolatis ; pani- 

 cula composita; floribus racemoso-umbellatis ; umbellis 10-20floris; 

 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.

155. Heptapleurum (Pterotropia) diptrenum (sp. nov.) : 

 arborescens ; foliis impari-pinnatis, junioribus inflorescentiaque dense 

 furfuraceo-puberulis demum glabratis ; foliolis 13-15 coriaceis oblon- 

 gis vel ovatis obtusis integerrimis basi cordatis brevissime petiolatis ; 

 panicula composita; floribus racemoso-umbellatis; umbellis 6-12- 

 floris ; stigmatibus 2 sessilibus ; ovario maxima parte supero biloculari 

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



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

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

 species must apparently be referred to Heptapleurum, Gffirtn. {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.
