Beccari and Rock — Prifchardia. 47 



Habitat.— Oahn, Waianae range, eastern side of the island in the left fork of 

 Makaleha Valley above a waterfall on the steep ridge, elevation bout 1200 feet 

 or more, at the foot of Alt. Kaala. A grove of this species was found first by 

 me when in company with Dr. and Mrs. H. L. Lyon in the spring of 1918. Speci- 

 mens were collected by Messrs. A. Holm and O. H. Swezey when I accompanied 

 the party on a collecting trip to that locality.

Observations. — This is a remarkable species and somewhat allied to the 

 Kauai species, especially perhaps to Pr. Hardyi. It is remarkable for the long 

 inflorescence which measures over seven feet in length, the small flowers, glabrous 

 panicles, and large leaves, which are not densely tomentose beneath as in the 

 Kauai species and Pr. Martii from Oahu, but covered with small, scattered, ellip- 

 tical, slightly fringed lepidia; the leaf blade is dark green on both sides.

Description. — A rather short stemmed palm, 3-5 m. high with a head of 

 robust, rigid leaves. The leaf blade measures about 80 cm. in length from the 

 ligula to apex, is of a thickish coriaceous structure, and deeply cut into numerous 

 segments; has the lower surface of a yellowish or slightly tawny color (when 

 dry), and is very densely clothed with an appressed felt or tomentum, composed 

 of conspicuous, nearly confluent lepidia, leaving very small patches of epidermis 

 uncovered; the lepidia are about as long as broad, very irregularly fringed with 

 relatively large hair-like curved and falcate hyaline cells ; the segments are rather 

 deeply parted into two very finely acuminate non-drooping points; central seg- 

 ments 4.5 cm. broad at their disjunction places. Petiole robust, about as long as, 

 or shorter than, the blade, covered in newly expanded leaves with (apparently 

 fugaceous) silvery scales on the upper surface and with a thin appressed tawny 

 tomentum underneath, the latter extending (but apparently also not permanently) 

 to the main costae. Spadices elongate, composed of 3 or 4 partial inflorescences 

 or panicles, each of which is sustained by a distinct peduncular part; the general 

 peduncular part is 85 cm. long in one specimen. Spathes rigid, chartaceous, 

 nearly glabrous, being sprinkled only here and there with silvery fugaceous paleae; 

 the panicles are about 20 cm. long, rather loosely branched, twice in their lower
