each side; the axes of the spikelets are zig-zag sinuous; the spathels are tubular- 
infundibuliform, truncate; involucre cupular, truncate, not or slightly protruding 
beyond the mouth of its spathel, Sometimes the long filiform spadices are viviparous 
or produce rooting leafy buds from the axils of the upper primary spathes.

OnSERVATIONS.— Prof. Udo Dammer forwarded to me in October 1905 a fruiting 
branehlet of this species, collected in Garowe Insel (=Deslacs Insel) and presented 
to the Herbarium at Berlin by the “Neu Guinea Companie.” The fruits, almost 
completely ripe, are spherical, 9 mm. in diameter, slightly smaller than those of 
Lauterbach’s No, 2814 in the Berlin Herbarium. 
A more slender form of this species has been collected by Missionary Peekel 
(No. 80. Herb. Berol) in Neu—Pommeru (German New Guinea) at Namatanai near 
Herbertshóhe. The sheathed stem is 11-15 mm. in diameter, and the leaf-sheaths are 
armed with short, broad-based, scattered, horizontal prickles; leaves about 50 em, long. 
Other specimens also collected by Missionary Peekel at Namatanai in New Mecklen- 
burg (German New Guinea) (Nos. 439, 440, 441 in Herb. Berol) have leaves l:10— 
1:30 m. long, oval in outline; the leaflets towards the lower third part of the 
rachis being the largest, 385-40 cm. long, 25-28 mm. broad. those of the middle 
somewhat shorter but not narrower; from the middle upwards they speedily decrease 
in length and slightly in width; the two uppermost are free at the base, 15 em. 
long, 10-15 mm. broad and have a very fine filament between them; the lowest are 
narrower, more approximate, horizontal or also deflexed. The leaf-sheath flagella 
are long and slender, uninterruptedly very closely armed with scattered or more or 
less confluent but not regularly whorled claws. A female spadix with immature 
fruits measures about 2 m. in length from the base to the uppermost partial 
inflorescence and terminates in a slender irregularly clawed flagellum, another metre 
long; the partial inflorescences, in one specimen, are 9, gradually decreasing: 
the intermediate appear the largest, about 50 cm. long and carry. 10-12 strongly 
curved spikelets on each side; occasionally the lowest spikelets are branched from 
the base. Every part of the spadix, and the fruits also, acquire a light-straw 
colour in herbarium specimens. |
