Genus Prioria

Author: Harms

Morphological description (Kingiod alternif Kingiod compl )
Medium to large evergreen trees , slashed wood usually exuding a green sap. Stipules very small, fugacious, leaving scars.

Leaves imparipinnate, (1-)3-6(or 7)-foliolate; petiolules annularly wrinkled. Leaflets alternate, largely equal-sided, with pellucid dots, glabrous.

Inflorescences axillary, racemose, simple, solitary or aggregate, or paniculate, shortly peduncled; rachis and branchlets rather loosely flowered, glabrous or hairy; bracts minute, scale-like, persistent; bracteoles usually 2, minute, often inserted at the base of a flower; pedicels short.

Flowers bisexual or rarely unisexual (see Note 2). Hypanthium often absent or obscure. Sepals 5, imbricate, usually with transparent dots, ciliate. Petals absent. Disk distinct in young flowers, connate with the stipe of the ovary, becoming obsolete in the mature flower. Stamens 10, bent in bud, hairy at base, exserted at anthesis; anthers medi-dorsifix, lengthwise dehiscent, introrse. Ovary sessile or subsessile, hairy, 1-ovuled; style developed or very short, glabrous or hairy.

Pods variable, often flattened, indehiscent; pericarp often hard to woody, rarely fleshy but fibrous.

Seeds with strongly folded cotyledons.

Six species distributed in India, the Pacific (Solomon Islands and Fiji), and Malesia (Philippines, Moluccas, New Guinea).

Evergreen forests, at low and medium altitudes.

1. The medium- to large-sized trees of Kingiodendron can be easily identified to the genus by a combination of the following characters:
a) slashed wood usually exuding a green sap,
b) leaflets with pellucid dots,
c) indehiscent pods, and
d) strongly folded cotyledons which can be easily observed in a section. However, fertile collections, especially fruiting material, are needed for further study of the species in this group (cf. Verdcourt, 1979: 93).
2. The flowers of this genus have been described as bisexual. However, some of them appear to be heterostylous, with fertile or (partly) sterile stamens. Verdcourt (1979: 93) stated that the possibility of functionally male or female flowers needs investigation.
3. Many sterile specimens have been collected, especially from Irian Jaya, which are so far unidentifiable to species.
4. Knaap-van Meeuwen (1970: 49) recorded the species Kingiodendron platycarpus Burtt from New Guinea and the Solomon Islands. According to Verdcourt (1977: 244-245; 1979: 97) this species does, however, not occur there.
