    Fruits
    Fruit unknown
    Distribution
    Indonesia: Papua Barat, KepalaBurung.
    Ecology
    The new species is known from only two collections, both from the Kebar subdistrict (Manokwari), where it is present in primary forest, on granites and volcaniclastic sediments; alt. 620 – 650 m (Davis 839).
    Conservation
    Lacking data on the extent of habitat disturbance and population consistency, the conservation status of Capparis kebarensis is as yet unknown and should be classed as IUCN (2001) category Data Deficient (DD).
    Phenology
    Flowering April – May (based on available specimens).
    Note
    Some other species from the Indonesian – New Guinean area can vegetatively resemble Capparis kebarensis. Among these are C. zippelianaMiq., which can be distinguished by its larger leaves, (8 –) 13 – 20 (− 26) × (4.5 –) 5 – 8 (− 10) cm, and flowers with longer gynophore 2 – 3.5 (− 4) cm, arranged in terminal panicles or axillary subumbels, and C. lanceolaris DC., differing in its larger flowers, with sepals 6 – 7 (− 10) × 5 mm and petals 8 – 11 × 4 – 6 mm, borne in axillary or terminal subumbels. Also similar in leaf morphology is C. erycibeHallier f., but this species is differentiated by its terminal panicles, smaller petals 4.5 – 6 × 1 – 4 mm, shorter stamens 5 – 6 (− 8) mm long and gynophore 2 – 5 mm long. In his revision of the genus Capparis in the Indo-Pacific area, Jacobs (1965) distinguished four sections, i.e. sect. Capparis L., sect. Sodada (Forssk.) Endl., sect. BusbeckeaBenth. & Hook. f., and sect. MonostichocalyxRadlk. This latter section includes c. 65 species in this area and is characterised by simple, 2-armed or stellate hairs, well-developed leaves, small to medium-sized flowers solitary at leaf axils or in inflorescences, all free sepals in bud, equal or subequal in each pair, and fruit mostly globose with leathery pericarp and obscure carpel sutures. C. kebarensis is placed in sect. Monostichocalix, showing simple and balance-hairs, leaves well-developed and persistent, flowers with sepals up to 6 mm long, all free in bud and equal in each pair, and petals up to 8 mm long. Jacobs (1965) distinguished several groups within this section, with C. kebarensis belonging to the Cataphyllosa-group due to the presence of 2-armed hairs, large-sized leaves (over 8 cm long) and subumbellate inflorescence. The Cataphyllosa-group includes several taxa distributed in SE Asia (eastern Himalaya, north-eastern India, Yunnan, Myanmar, Laos, Philippines), with a single representative, C. pubiflora DC., extending to Malaysia and Indonesia. Compared with other species of the group, C. kebarensis is noteworthy for its reduced inflorescence, with flowers arranged in sessile subumbels or solitary. Among the representatives of the Cataphyllosa-group, C. kebarensis most closely resembles C. pubiflora. The latter species mainly differs from C. kebarensis in the presence of stipular thorns (except in material from the Philippines), the smaller number of nerve pairs, racemose inflorescence, wider petals and larger ovary (Table 1).
