Beccari and Rock — Pritchardia. 57 



sprefiding filaments; ovary turbinate; petals irregularly lanceolate, having more 

 or less wavy acute or acuminate apices. The fruit, when thoroughly mature, is 

 globose-ovoid, or subobovoid, acutely mucronate by the remains of the sterile 

 carpels, symmetrical at the base, 35-37 mm. long ; 30-33 mm. through ; o£ a 

 hazel nut brown color, and \\\t\\ a nearlv polished, slightly uneven surface; the 

 young fruit is elliptical or subobovate-elliptical, and tapering towards the base; 

 mesocarp grumose, not fibrous ; endocarp thin but very hard. Seed spherical. 

 Fntifiiig perianth depressedlv pedicelliform : the calyx callose; the staminal and 

 corolla tube form a narrow toothed ring. 



Habitat. — The Island of Molokai. It was collected by Professor Rock 

 in May, 1919, in Wailau A^alle}', where presumably it was a cultivated plant. 

 No. 16000 of the College of Hawaii Herbarium. 



It differs from all the Pritchardias known to me in its very short, sharplv 

 3-toothed, campanulate calyx, and in the ^'ery elongate corolla and staminal tube, 

 which protrudes considerably outside the mouth of the calvx. It is also char- 

 acterized by its glabrous floriferous branchlets, by the large leaf blade, green on 

 both surfaces, and sprinkled underneath with minute lepidia, but otherwise glab- 

 rous, and cleft into relatively long segments, which have extraordinarilv long, 

 hanging, filamentose apices ; and finally by its rather large globose-subobovoid, 

 symmetrical fruit. It does not seem to me closely related to any other species, 

 but it may be, however, located in the conspectus with the species having glabrous 

 floriferous branchlets, and fruits over 3 cm. in diameter.

Description. — A beautiful palm having a slender, slightly sinuous and closely 

 ringed stem 15-18 m. high, 20 to 30 cm. in diameter, with a large globular crown 

 of leaves (Rock). The leaves of young plants have petioles up to 3 m. long 

 reduced, however, to 1.20 m. in the adult plant. Leaf blade nearly explanate, 

 verv large, nearly orbicular, of a thinly coriaceous, tough structure, green, dotted 

 rather densely on the lower surface, with small, hyaline, irregularly elliptical, 

 fringed lepidia; the intermediate segments considerably narrower, more deeply 

 cleft and with slenderer and more acuminate, more or less drooping points. The
