    Type
    Type: Indonesia, West Java, PasirWalang, Nanggerang, 17 Aug. 1913, Backer 8729c, fruiting (holotype BO!, isotype K!).
    Habit
    Slender clustering rattan climbing up to 10 m
    Stem
    Stem without sheaths about 4 – 6 mm diam., with sheaths about 8 mm diam.; internodes to 6 – 10 cm long
    Leaves
    Leaf cirrate, 1.5 – 2.2 m long including cirrus and petiole; sheath armed with delicate, pale straw-coloured, solitary triangular spines to 15 mm long with slightly bulbous-bases, interspersed with much finer shorter dark bristle-like spines c. 2 – 5 mm long, low horizontal ridges also present between the larger spines; sheath mouth armed with few slender erect straw-coloured spines to 15 mm long; knee conspicuous, sparsely armed as the sheath; ocrea absent; petiole 21 – 27 cm, 2 – 4 mm diam., wider at base, flat adaxially, rounded abaxially, armed with solitary pale spines, 2 – 3 mm long; rachis up to 1.85 m, with few, small, irregularly arranged grapnel spines abaxially; cirrus 6.8 – 7 cm long, cirrus grapnel spines arranged irregularly; leaflets 15 on each side of the rachis, regularly arranged, acuminate, basal leaflets 19.7 – 20.8 × 1 cm, apical leaflet 16.2 × 1 cm, with few reddish bristles towards base on abaxial surface of mid-rib and on other major veins, leaflet margins armed with very few bristles, increasing in density towards leaflet apex, transverse veinlets inconspicuous
    Inflorescences
    Pistillate inflorescence erect at first, becoming pendulous in fruit, branched to 2 orders, to 20 cm long; peduncle 64 mm long, c. 3 mm diam.; prophyll to 8 – 15.4 cm long, c. 0.7 – 1 mm wide, sparsely armed with straw-coloured spines to 5 mm long; first order branches with c. 8 rachillae; rachillae 30 – 50 × 2 mm, irregular in length Staminate inflorescence unknown Inflorescence bracts scarcely boat-shaped, split to the base, not enclosed by the prophyll, usually falling at anthesis, often only the prophyll remaining
    Fruits
    Fruit oblong to obovoid, c. 8 – 20 × 7 – 10 mm including beak 1 mm, with c. 12 vertical rows of shallowly channelled scales, creamy brown when dry, with entire, but uneven darker margins
    Seeds
    Seed c. 12 × 8 mm, oblong, rugose with a groove on one side, the surface covered with numerous deep pits on the other side; endosperm ruminate; embryo basal-Fig. 1.
    Distribution
    Endemic to West Java and currently only known from two locations (Map 1).
    Ecology
    Mossy hill forest on the ridgetop up to 1000 m asl.
    Conservation
    Daemonorops sedisspirituum is known from two locations, both in West Java, in mossy hill forest. Neither locality is in any way protected and based on the most recent Google Earth imagery, the area appears to be covered with crops, reforestation and a main road (https://maps.google.co.id/ — as seen 9 Nov. 2012). Recently one of us (HR) went to the collection sites and noted that most of the forest has been converted to agriculture, human settlement, grass fields and a main road. Because of this, this species can be considered as Critically Endangered (CR1abiii) following the IUCN guidelines (IUCN 2001). This rattan should be searched for in remaining fragments of submontane forest to the south of Bandung.
    Phenology
    Based on herbarium specimens, Daemonoropssedissprituum fruits in April and August.
    Note
    The epithet means “seat of the Gods” or “where the spirits live”, this being the meaning of the Sundanese Parahyangan, the old name for this part of upland West Java. In the sterile state the new species is immediately distinguishable from Daemonoropsoblonga by its very slender stems and scattered rather than grouped leaf sheath spines. At present we are retaining D. oblonga as distinct from the very widespread and variable D. hirsuta, while recognising that the whole complex of species related to D. hirsuta throughout its wide range is in need of revision. This species belongs to the complex of species related to Daemonoropsoblonga and D. hirsuta in fruit characters, but it differs in the much more slender stems, the sheath covered by solitary, short, bulbous-based spines, scattered rather than grouped, and the oblong rugose seed, with a groove on one side.
