80. Zanthoxylum Kaviense (Gray, 1. c. p. 354 ; H. Mann, 1. c. 

 p. 318): " inerme, glabrum ; foliis alternis pinnatis 3 - 5-foliolatis ; 

 foliolis coriaceis ovalibus integerrimis haud punctatis ; paniculis axil- 

 laribus compositis; fructibus stipitatis"; — floribus tetrameris ; calycis 

 lobis ovato-subulatis petalis fl. masc. lanceolatis triplo, fl. foem. lineari- 

 ligulatis quadruplo brevioribus ; antheris ovalibus ; ovario solitario. — 

 Kauai. Hawaii. — The fruit has been described from the specimens of 

 the South Pacific Exploring Expedition. I have described the flowers 

 from a specimen, probably of the same species, collected on Hawaii by 

 Remy, but differing in the thinner texture of the leaves, which appear 

 with the flowers. Calyx four-lobed ; the lobes ovate-subulate, about 

 three fourths of a line long, in the male flowers thrice shorter than the 

 lanceolate petals : stamens four, a line in length ; filaments capillary ; 

 anthers oval. In the female flower the sepals are four times shorter 

 than the linear-ligulate petals, which are imbricated in aestivation ; 

 stamens reduced to four glands ; ovary unilocular, stipitate ; stigma 

 globular. (Remy, 614.) 



81. Zanthoxylum Maviense (H. Mann, 1. c. p. 319) : inerme, 

 pube tenuiter velutina cinereum ; foliis alternis 3-foliolatis ; foliolis 

 coriaceis ovalibus (lateralibus basi hinc excisa valde ineequilateris) 

 integerrimis haud punctatis ; paniculis axillaribus ; coccis solitariis 

 estipitatis lunulato-ovoideis. — Maui. — The specimen is apparently from 

 an unarmed tree, bearing mature fruit only ; it is cinereous with a fine 

 velutinous pubescence, especially on the under surface of the alternate 

 trit'oliolate leaves. Petioles fifteen to twenty lines long. Leaflets 

 ovate, truncated at the base ; the two lateral ones unequal, the upper 

 base being three lines shorter than the lower, two to two and a half 

 inches long by fifteen to twenty lines wide. Panicle several-flowered. ' 

 Carpel solitary, estipitate, four to five lines long, lunulate-ovoid, becom- 

 ing two-valved ; the endocarp adnate. Seed solitary, filling the cell. 

 Known only from Remy's collection. (Remy, 615.) 



82. Zanthoxylum (Blackburnia) dipetalum (H. Mann, 1. c. p. 

 319) : inerme, glabrum ; foliis alternis 3 - 9-foliolatis ; foliolis coriaceis 

 oblono-is vel ovatis integerrimis punctatis ; paniculis florura sterilium 

 compositis ; petalis 2 ovalibus crassissimis aestivatione valvatis calyce 

 4-dentato quadruplo longioribus ; antheris oblongis : — flores fertiles
