very few unequal spikelets of but few flowers each; the largest spikelets—the 
lower ones—are 8-10 mm. long, and have only 6-8 irregularly set flowers; 
their axis is extremely slender and capillary; épathels inconspicuous; involucre 
very small, discoid, orbieular. Male flowers small, 4-5 mm. long, asymmetrically. 
subtrigonous-lanceolate, acuminate; calyx very small, deeply  3-dentate; petals 
lanceolate, sinuous, acuminate, several times longer than the calyx; stamens longer 
than the corolla, anthers basifixed, linear-sagittate ; pollen yellow, like sulphur powder. 
Female spadiz elongate, rather slender, cupressiform; the panicle in one specimen 
is 65 cm. long (without the pedicellar part) and bears 6-7 partial inflorescences; 
the axis is rigid, somewhat flattened, 7-8 mm, broad at its base; the partial 
inflorescences are erect, appressed to the axis, 6-10 cm. apart and each 
15-20 em. long with 8-10 spikelets that are somewhat irregularly distichous ; 
secondary spathes very short, reduced to a very narrow membranous ring, acute 
or acuminate at one side; spikelets erect, slender, 6-8 cm. long, conspicuously rusty- 
furfuraceous; their axis angular, slender, sinuous; spathels very shortly annular; 
involucrophorum elongate, pedicelliform, 3-5 mm. long, trigonous, with a very short 
limb; involucre very slightly raised above the involucrophorum and having a very 
rudimentary annular limb surrounding the relatively large and convex disk upon 
which the female flower rests; the areola of the neuter flower is niche-like and 
elongate. Fruiting perianth very broadly obconical; the calyx has 3 broadly 
triangular, acute teeth; the segments of the coroila are also very broadly triangular, 
callous and smooth at their base, otherwise strongly, striately veined. Fruit ellipsoidal, 
2 cm. long, 15 mm. broad, shortly conically beaked. crowned with the remains of the 
3 small stigmas; scales arranged in 15-16 longitudinal series, of a shining light 
greenish-yellow or straw colour, narrowly but deeply ‘chennelled along the centre 
otherwise convex; the margins very narrow, and, like the blunt point, slightly arkis 
and dall. Seed ovoid, with a flattish base, more convex on the outer than on the 
raphal side; the chalazal fovea remains almost in the centre of the raphal side 
formiug a cylindrical pit that penetrates to the centre of the albumen; the latter 
bony and ruminate with very narrow black channels.

OBSERVATIONS. —Of this species l have seen the authentic specimen in the 
Herbarium of Buitenzorg and a portion of it in that of Utrecht. Moreover 
I have received, from the Botanic Garden of Buitenzorg, a male spadix and d 
leaf of a plant cultivated there under the name of “ Calamus macropterus 
Miq.— Angah— Menado”, which almost certainly has the same origin as the 
specimen . upon which Miquel founded the species. I must observe, however, 
that the portions of the leaves which in the Herbaria of Buitenzorg and Utrecht accom 
pany the fruits of D. macropterus, and correspond to the description of Miquel, are 
quite different from tbose of the male plant cultivated at Buitenzorg under that name, 
and apparenily belong to another species, 
It is therefore safe to consider D. macropterus as founded only on the fruiting 
specimen described above, and reproduced in Plate 37, and to wait for further evidence 
as to conspecificity of the male plant of which I have also given the description.
