Beccari and Rock — Pritchardia. 23 



a/ Fruit mediocre, 18 to 23 mm. in diameter; spherical or nearly so, (not 



exactly known of Pritchardia glabrata). 

 b. Leaf-blade more or less powdery waxy or glaucescent beneath. 



c. Leaf-blade distinctly waxy-pulyerulent and devoid of lepidia beneath. 

 Panicle having the lower branches digitately 3 to 4-partite. Florifer- 

 ous branchlets rather slender. Calvx of a hard nearly woody struct- 

 ure, especially at the base, very faintly veined in its upper part only; 

 petals very faintly striate outside. Fruit globose, usually slightly 

 longer than broad (18 to 20 by 17 to 19 mm.). Fruiting perianth 

 conspicuously pedicelliform, cylindrical, 4 mm. long and high . 



. . 4. Pritchardia Hillebrandi Becc. — Hawaiian Islands. 



c.^ Leaf-blade slightly powdery-waxy and devoid of lepidia beneath. 

 Panicle composed of few simple or slightly divided, thickish (4 to 5 

 mm. through), polished, floriferous branchlets. Calyx not veined, of 

 a hard texture. Fruit spherical, 14 to 16 mm. in diameter. Fruiting 



perianth pedicelliform, subcampanulate 



5. Pritchardia insignis Becc. — The pre- 

 cise locality unknown. Possibly from some of the Hawaiian Islands. 



c.^ Leaf-blade slightly powdery-waxy and dotted with small, almost 

 rudimentary, lepidia beneath. Panicle elongate, much branched, the 

 lower branches divided into 10 to 12 slender floriferous branchlets. 

 Petals conspicuouslv pluri-costulate. Fruit nearly spherical, 19 to 20 

 mm. long, 18 to 19 mm. in diameter. Fruiting perianth 4 mm. high, 



ventricose-pedicelliform 6. Pritchardia 



remota Becc. — Nihoa or Bird Island (Hawaiian Islands). 



(not powdery-waxy). 

 b.^ Leaf-blade green on both surfaces or only paler beneath than above 



c. A tall plant. Leaf-blade rather closely dotted beneath with small, 

 orbicular, or oblong lepidia. Calyx nearly smooth, of a hard texture 

 and nearly woody at the base. Fruit spherical or a trifle narrowed to 

 the base, 23 mm. in diameter. Fruiting perianth pedicelliform, cylin- 

 drical or slightly campanulate 



. . . 7. Pritchardia affinis Becc. (forma typica). — Hawaii. 



c' A smaller plant than the type. Leaf-blade dotted with minute, 



spaced lepidia. Fruit spherical 20 to 21 mm. in diameter 



Pr. affinis var. halophila Becc. — Hawaii 



c.- Leaf-blade sparingly dotted on the lower surface with very small 

 lepidia. The ripe fruit subspherical, the immature one obovate, dis- 

 tinctly narrowed to the base, 25 mm. long, 20 to 22 mm. in diameter 

 Pr. affinis var. rhopalocarpa Becc. — Hawaii. 



cf' Rather small, 3 to 4 mm. high. Leaf-blade devoid of lepidia. Fruit 

 obovate, distinctly narrowed to the base, 20 to 22 mm. long, 16 to 17 

 mm. in diameter . . . Pr. affinis var. gracilis Becc. — Hawaii.
