184 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [ M. upoluense 
Osservations.—It is easily distinguishable from the other known species of 
Metroxylon, sectio Celococcus, by its leaves having narrow very long-acuminate 
rigid leaflets, glaucous beneath ; by the glabrous appearance of the spikes ; by the 
cylindraceous relatively large flowers, having the filaments of the stamens united 
in their basal part with the corolla, and forming a distinet elongate collar at its 
throat, before becoming free and subulate; by the ovary reaching, with the summit 
of the style. only to the base of the free part of the filaments ; and especially by 
the obpyriform, frequently more or less angular or obpyramidate fruit, which has the 
seed in its upper part, while its lower half is filled with the spongy tissue of the 
mesocarp ; and finally by the seed being covered with a relatively copious 
integument, whereas this in other Ivory supplying species Celococcus is very 
scanty. 
PLATE: 109.—Metroxylon Warburgii Bece.—Spike-bearing branch bearing female- 
hermaphrodite flowers ; leaflet from an intermediate leaf of a full-grown plant : 
from the plant that flowered at Singapore, Ridley No. 3171. Fruits from Perret’s 
specimens in Herb. Martelli. One of the fruits cut vertically to show the position 
of the seed. See analytieal plate V—figs. 8—11 which represent the analyses of 
the female flower of M. Warburgi Becc. 
5. METROXYLON UPOLUENSE Becc. sp. n. 
Descrtprion.—Frurt obpyriform, 33 mm. long (in one specimen) and 25 mm. 
broad in its uppermost part, and thence gradually attenuate below to a narrow 
base, rounded and slightly umbilicate above, and surmounted by a small muero. 
Scales in 24 longitudinal series, glossy, straw-coloured and with a shade of chestnut- 
brown near the margins. grooved broadly in their posticous pàrt, and narrowly and 
faintly anticously ; the apices slightly produced and appressed ; the margins thin 
minutely erosely-toothed. Pericarp on the whole relatively thick (4 mm.) and with 
the lower third part of the fruit filled with a spongy mesocarp, the seed being in 
the upper two thirds. Seed erect, not seen mature by me, but apparently of the 
structure usual in Metroxylon. Other parts unknown. 
HaBrrAT.—Cultivated at Upolu in Samoa ( Rechinger). 
OssERvATIONS.—I have seen of this curious species only one fruit, which differs 
from those of the other known species by its regularly pyriform shape, and by 
its scales being arranged in 24 vertical series, a character by which it comes into 
the section C'elococcus, despite its very small size. It shows, however, unmistakable 
affinity to M. Warburg, from which it differs by its fruit being considerably 
smaller and less spongy at the base inside.
