Description
Saraca celebica is a tree which grows up to Script error: No such module "convert". in height. Leaves are 3-4 rows of jugate leaflets, growing Script error: No such module "convert". long, with a short petiole, measuring Script error: No such module "convert". long and with a rachis Script error: No such module "convert". long, blackish-brown when dry. Leaflets are subcoriaceous and glabrous, elliptic-oblong to oblong-lanceolate, and rarely ovate, measuring Script error: No such module "convert". long by Script error: No such module "convert". wide with Script error: No such module "convert". petioles. Leaflets above are usually not larger than the lower ones and leaf bases are often accompanied by small marginal glands.[2][3]
Flowers are orange-red and fragrant.[3][4] Corymbes are erect, compact, about Script error: No such module "convert". wide, glabrous, with branches up to Script error: No such module "convert". thick. Bracts and bracteoles are caducous, subequal in size and shape, fusiform, ovate or obovate, with an obtuse or acute tips, growing about Script error: No such module "convert". long and Script error: No such module "convert". wide. Calyxes are Script error: No such module "convert"., rarely Script error: No such module "convert"., long, Script error: No such module "convert". thick. Pedicels are Script error: No such module "convert". long for the section between the calyx tube and bracteoles. Calyx lobes are oval or oblong, Script error: No such module "convert". long by Script error: No such module "convert". wide, with an obtuse apex. Stamens amount to 4, rarely 6. Stamens have filaments growing Script error: No such module "convert". long and anthers measuring about Script error: No such module "convert".. Ovary stems are Script error: No such module "convert". long, with ovaries being Script error: No such module "convert". long. Styles are Script error: No such module "convert". long.[2][3]
The fruits are pods, numbering 1-6 per corymb, woody, oblong to oblong-lanceolate, measuring about Script error: No such module "convert"., being up to about Script error: No such module "convert". thick; the base is obliquely cuneate and the top is acute-acuminate, Script error: No such module "convert". beaked, 5-6 seeded. Dry mature valves are somewhat coiled, about Script error: No such module "convert". thick, with the inside containing traces of seed compartments. Immature pods are flat with somewhat thickened margins. Mature seeds are suborbicular, more or less depressed at the side of the hilum, about Script error: No such module "convert"., hard, with a rounded edge, and a glossy dark brown surface. The hilum itself is small, about Script error: No such module "convert"..[3][4]
Taxonomy
Saraca celibata was identified and described by Willem Jan Jacobus Oswald de Wilde in the Dutch journal of botany Blumea in 1967.[2] A description of the fruits was missing from the original description, this was included in a 1981 Blumea article describing the then newly identified S. monadelpha.[4]
Etymology
Celibata refers to Celebes, the name given to the island of Sulawesi by Portuguese explorers, to which it is endemic. A direct translation of Celebes is unclear, but it might be considered a Portuguese rendering of the native name "Sulawesi".[5]
Distribution and habitat
The trees were observed in central and east Sulawesi and were common along the Larona River, flowing from Lake Towuti. They grow along streams at a low altitude up to about Script error: No such module "convert"..[3][4]
Ecology
S. saraca was observed to flower abundantly in June; collections of flowers were made in September and October. Mature seeds appeared to be rare in herbarium collections.[4]
