Beccari and Rock — Pritchardia. 6i 



Habitat. — Discovered by Professor Rock in August, 191 1, at about 700 m. 

 elevation in the rain forests of the northern slope of the Koolau range, Punaluu 

 on Oahu. 



Observations. — Easily distinguishable by the leaf blade being subaureous 

 tomentose underneath; by the minutely rust3r-tomentose floriferous branchlets, 

 and especially by the large obpyriform fruit, which has its lower third part solid 

 internally. The fruit represented in W'ebbia i c. fig. 16 is about one-tenth smaller 

 than natural size.

(Plates XIII, A, B; XXIV, R) 



Description. — A palm 20 m. or more high, Avith a slender trunk 20 cm. or 

 more in diameter; leaves larger than in Pr. minor, flexuous with drooping seg- 

 ments; leaf blade 100 cm. long from the ligule to the apex, coriaceous; lower 

 surface densely tomentose with appressed light golden yellow, much fringed 

 lepidia in the young and old leaves; segments 60, the central ones nearly 5 cm. 

 wide at their disjunction places, parted about 35 cm. into two acuminate some- 

 what flexuous points, glabrous above with the exception of the upper costae 

 which are covered with a silvery white coarse woolliness ; ligule almost truncate. 

 Petioles about 75 cm. long, about 3.5 cm. broad at the ligule, covered with a deep 

 rufous deciduous tomentum as are the lower costae. Spadix long, drooping, 

 branching into three distinct panicles, 2.26 m. long, 6.5 cm. broad at the base. 

 Spathes long tubular in their lower part, expanded above into an elongate acumi- 

 nate strongly chartaceous to coriaceous blade, which later becomes slashed ; spadix 

 and spathes covered with a detachable rufous tomentum ; panicles covered Avith 

 a short, not detachable rufous tomentum; branches simple, straight, erect, only 

 the two lowest branches, branching again once or twice; branchlets zigzag- 

 sinuous, 10 to 12 cm. long, when with fruit. Ploivcrs spirally alternate, 11 to 12 cm. 

 long when unopened, 3.5 cm. in diameter, oblong, apiculate; cah'x cyathiform, 

 puberulous, three-toothed, ver}^ inconspicuously striately veined and onty imme- 

 diately near the teeth; corolla longer than the calyx 6.5 mm. long, the segments 

 oblong, bluntly acute, not prominently striate; staminal ring reddish, protruding 

 1.5 mm. beyond the calyx; the filaments subulate, 1.5 mm. long; anthers linear, 

 3 mm. long, broader at the base, slightly emarginate at the apex; ovary 

 smooth, truncate at the apex, with a trigonous, sulcate style; stigmas punctiform. 

 Fruit asymmetrical, ellipsoidal to obovoid, rounded at the apex but apiculate by 

 the remains of the abortive carpels and at the ventral side somewhat flattened, 

 black when ripe, striate, thickest in the upper third. 2 cm. long, 16 mm. thick; 

 pericarp very thin, less than i mm. thick when dry; mesocarp very scanty; 

 endocarp thin, pale yellowish, brittle. Seed ovoid 12 to 13 mm. long, 10 mm. 

 wide, rounded at both ends, flattened on the raphe side; hilum irregularly ovoid; 

 embryo 2 mm. above the hilum. Fruiting perianth cylindrical, truncate, with 

 spreading staminal cap.
