Morphological description (spectab Endertia compl 431603 )
Tree up to 20--35(--80) m high and 37--50(100) cm in diameter, not or hardly buttressed.
Leaves paripinnate, 2--4-jugate; petiole and rachis 7--24 cm long, glabrous. Leaflets chartaceous to subcoriaceous, elliptic, ovate, or broadly elliptic, sometimes obovate, 10--23 by 5--9.6 cm; apex shortly acuminate or acuminate, sometimes caudate; base obtuse, rotund, or slightly cuneate, rarely attenuate; glabrous on both surfaces; nerves 7--9 per side; veins obscurely reticulate on both surfaces; petiolules 5--8(--11) mm (spectab Endertia fl branch FM32).
Inflorescences usually 10--20(--26) cm long, puberulous; bracts and bracteoles triangular or deltoid, c. l mm long; pedicels 4--12 mm, articulated at the apical end.
Flowers white (spectab Endertia flower FM32 ). Hypanthium 4--7 mm long, puberulous outside, glabrous inside. Calyx lobes 4, ovate, oblong-elliptic, or suborbiculate, 3--4 mm long, puberulous outside, subglabrous inside. Petals white or light yellowish when young, then red orange, suborbicular, obovate, flabellate, 4.5--5 by 2.5--4 mm, with distinct lateral veins, clawed at the basal part (c. l mm long), glabrous except ciliate on the margin. Stamens and staminodes 1.5--8 mm. Ovary 3 mm long, hirsute to densely lanate, sometimes only along the sutures, glabrescent or glabrous in the central part; style 4.5--5.5 mm.
Pods up to 26 (or more) by 4--7 cm, distinctly veined when young, smooth or nearly so when old (spectab Endertia pod/seed FM32).
Seeds 3--4.2 by 3 cm.
Distribution
Malesia : Borneo (Kalimantan).
Habitat & Ecology
In lowland forest, sometimes found occurring on sandy, loam soil, or on limestone, up to 1000 m altitude. Flowering in April and October; fruiting in February, October and November
Note
Van Steenis & De Wit (1947: 324) cited the type for their new species Endertia spectabilis as "Nieuwenhuis 947 (18.V.1897), cultivated in Hort. Bot. sub I.B.90, collected in 1930". There is one herbarium specimen of Nieuwenhuis 947 in BO, as Dr. Elizabeth Widjaja (in litt.) informed Ding Hou. This specimen and the one collected in 1930 from the tree that originated from Nieuwenhuis' collection from Kalimantan, cultivated under no. I-B-90 in the Botanic Garden Bogor, can be considered as authentic material of Endertia spectabilis , so both are treated here as syntypes. Several good fertile specimens were in the course of time collected from the same tree in the Garden and some herbarium specimens were also collected from the wild in Borneo.
