thick, about 4-5 mm. through, permanently clothed \vith a dense tomentum of 

 rather long, ruffled, light-colored hairs, are somewhat angular and sinuous and 

 marked with rather conspicuous, irregularly spirally alternate notches for the 

 insertion of the flowers. The bracteole existing at the base of every flower is 

 inconspicuous, being hidden by hair, flozvcrs (unopened) lo-ii mm. long, 

 4-5.5 mm. through in their lower part, slightly narrowed above to a conical, 

 obtusely trigonous, acute juiint; calyx glabrous subovate urceolate, not veined, 

 of a thickish hard structure, shortly solid at the base, slightly restrained at the 

 mouth, and with 3 rather acute teeth; corolla not quite twice as long as the 

 calyx, the segments elongate-triangular, acute, marked externally by 7 explanate 

 ribs separated by narrow furrows : staminal ring slightl}- protruding beyond the 

 calyx ; filaments subulate from a broad base, remaining erect after the anthesis ; 

 anthers linear-sagittate ; ovary turbinate, strongly sculptured above, and conically 

 narrowed into a trigonous, sulcate, thickish style. Fruit apparentlv ovoid and 

 relatively large (not seen mature). 



Habitat. — First discovered by ]\Ir. J. Lydgate on the Kohala Ridge on the 

 island of Hawaii: collected again July, 1910, by Professor Rock (with flowers 

 only) in the classical locality, above Awini, at about 1000 ni. elevation, in a dense 

 tropical rain forest (Rock No. 8820). 



Obscri'atioiis. — In the densely hirsute floriferous branchlets it approaches 

 Pr. arcciita and Pr. criostacliya. From the first it differs in the leaf blade which 

 is apparentlv glabrous underneath, but sprinkled really with minute, punctiform 

 lepidia; whereas in Pr. arcciiia. the lower surface is appressedly subaureous-tomen- 

 tose, and in Pr. criostacliya. is covered with relatively large, hyaline, nearly con- 

 fluent, scale-like lepidia. 



Lydgate's specimen, which fixes the type, is accompanied in the Berlin Her- 

 barium bv two immature fruits, ovoid, acute, about 3 cm. long, and 18-19 mm. 

 through.

Pritcliardia lanigcra Becc. has been found by me in the mountains 

 back of W'aimea, Flawaii. on the fiat swampy plateau at an elevation of about 

 4000 feet ; there it is a palm with a stout trunk and very rigid leaves with non- 

 drooping segments ; the spadix is usually simple, but only in one instance did 

 I come across a second very small panicle developed. The mature fruits of 

 Pr. lanigcra Becc. are as vet unknown, but from old remnants of fruits found on 

 the ground beneath the palms, and from germinated, and growing ones it can be 

 seen that they are not so large as those of Pr. montis-kca Rock, to which the 

 species is also related. Pritcliardia lanigcra is evidently scattered throughout the 

 Kohala mountains ; on the high plateau back of W'aimea it grows among stunted 

 bog vegetation in sphagnum moss, with Metrosidcros, Clcrinoiitia parvifiora, Broiis- 

 saisia, etc. The trunk is usually not more than 20 feet in height. Unfortunately 

 only one of the many palms of this species examined had flowering panicles and
