acuminate blades. The flowering panicle is about 20 cm. long, ratlier densely 

 twice branched in its lower part, and simply above. Floriferous l)ranchlets glab- 

 rous, spreading, very slender (i mm. through, or thereabouts), zigzag sinuous 

 between the flowers. Floral bracteoles extremely fine, setiform. Plozccrs not 

 quite regularly alternate-bifarious ; just before expansion are linear-oblong, rather 

 suddenly, and obtusely apiculate. 8 mm. long, 2.5-3 "'"^i- through : calvx of a 

 subfleshy-coriaceous texture, campanulate, very slightly thickened at the base, 

 very minutely 3-toothed, distinctly marked by several veins converging to the 

 teeth : corolla two and a half times as long as the calyx, the segments broadly 

 linear, rather strongly striate-costulate externally; staminal ring rather consid- 

 erably produced above the calyx : filaments very slender and relatively long, 

 spreading or arched at the time of anthesis ; anthers lanceolate-sagittate, bluntish; 

 ovary turbinate, sculptured above, and narrowed into a trigonous sulcate style; 

 stigmas punctiform. The full grown yet not thoroughly mature fruit is exactly 

 spherical. 2 cm. in diameter, centrally topped by the small remains of the sterile 

 carpels and style; the surface is very minutely uneven, and of a rather dull 

 hazelnut color. Pericarp (of the mature fruit) hard, not quite 2 mm. thick, gru- 

 mous with very few fibers. Fr;//V/;/o- pcrianili nearly explanate ( non pedicelli- 

 form) the calvx being callous but depressed. 



Habitat. — The Island of Lanai, one of the smaller forested Islands of the 

 Hawaiian group. Professor Rock, to whom I am indebted for the specimens 

 from which the above description is derived, writes to me that this palm "grows 

 at the head of the enormous and deep gorge known as Maunalei, at an elevation 

 of 550-660 m. I saw plants of it often, but as they grow on inaccessible cliffs 

 it was impossible for me to collect them and Mr. George Munro, manager of the 

 Lanai Ranch Co., secured the specimens for me." 



Obscn'atioiis. — There are no striking diagnostic characters for distinguish- 

 ing at once this species from the allied species, and especially from Pr. affinis, 

 which it resembles in general habit. It is. howe\-er, well characterized by the leaf 

 blade being almost ecjuallv green on both surfaces, but closely spotted underneath 

 by minute punctiform or linear, rusty lepidia ; by the very slender floriferous 

 branchlets with nearly bifarious flowers ; by the narrow unexpanded flowers ; by 

 the calyx campanulate, veined, fleshy coriaceous, not, or but very slightly thick- 

 ened at the base; by the striate-subcostulate petals, and especially by the quite 

 spherical, rather small fruit, carried on a nearly explanate (non pedicelliform) 

 perianth.
