492 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. CC. fertilis 
faintly striately veined; stamens with very thick filaments; anthers sagittate with 
obtuse point and auricles; rudimentary ovary as long as the stamens, divided into 
3 linear-subulate bodies. The spikelets are very compact on account of the very 
abbreviate secondary spikelets they bear; on this account the spadix is only 
apparently simply decompound.—Other parts unknown. ! 
Hanrrar.— German New Guinea: Bismark Ebene, at 100 m. elevation, ( Lauterbach 
No, 2488 in Herb. Berol. )—Native name ** Schiih.” 
OBSERVATIONS.—A species very characteristic by its short leaves with few broad 
l-costate grouped leaflets, the two of the summit highly connate; by the short male 
spadix with dense partial inflorescences and by the not distinctly bifarious flowers 
on the spikelets. Perhaps the affinities of C. Lauterbachii are with those of the group 
of C. macrochlamys, if I may judge from the remains of an apparently large ocrea. 
Of C. Lauterbachii I have seen only an entire leaf and a male spadix without 
the summit. 
Pirate  227.—Calamus Lauterbachii Bece. An entire leaf; male spadix.—From 
Lauterbach’s type-specimen in Herb, Beroi. 
196. CALAMUS FERTILIS Becc. sp. n. 
Description.—Female spikelets 15-18 em. long, rigid, vermicular, cylindraceous, 
slightly curved and  flexuous, terminating in a slender mucro, composed of 20-24 
tubular-infundibuliform almost symmetric spathels, which are horizontally truncate and 
decayed at the margin and covered with a removable fuscous-furfuraceous indumen- 
tum; involacrophorum short, cupular, with a short truncate limb and containing two 
equal collateral involucres and therefore two equai female flowers; the involueres 
cupular, united by their bases and each furnished on its inner side with an indistinct 
or not sharply defined ovate areola for the reception of a neuter flower, so tbat 
apparently two sterile flowers are in contact between the two fertile ones. Female 
flowers about 5 mm. long. Fruiting perianth split and explanate under the fruit and 
marcescent. Fruit ovate with a broad base, very shortly and suddenly beaked, 18 
mm. long, 10-11 mm. broad ; scales in 18 series, yellowish-brown ; narrowly and 
neatly channelled along the middle with a narrow very dark intramarginal line, the 
margins very narrowly scarious and finely erosely toothed, the tip short obtuse very 
dark. Seed subglobular, about i cm. long, 8 mm. broad, 7 mm. thick, slightly 
flattened on the raphal side with a very slight depression in the place of the 
chalaza, irregularly pitted on the back; albumen bony, equabie ; embryo basal.— 
Other parts unknown. 
‘Hasrrat.—British New Guinea; on Mt. Dayman, discovered by W. E. Armit 
in 1894 and forwarded to me by the late Baron F. von Mueller. : 
OssERVATIONS.—I have seen of this only 3 spikelets with a few bruised fruits and 
iwo entire mature seeds, but these parts are so unlike the corresponding ones of 
the generality of the species that I have ventured to establish on them a new 
one, Only 2 or 3 other Calami have constantly soilateral female flowers at each
