Ceriops

‘Yellow Mangroves’

Ceriops Ceriops decandra leaves

3 species in Australia

Ceriops Arn. (1838) is an Indo-West Pacific genus, and member of the small pantropic family Rhizophoraceae R.Br. consisting of 16 genera and around 120 species of trees and shrubs. Four genera are found exclusively in the mangroves and all are notably viviparous including, Bruguiera, Kandelia (DC.) Wight & Arn., Rhizophora and Ceriops. Ceriops are distinguished from other Rhizophoracaeae by calyces with 5(-6) valvate, blunt lobes, 10(-12) stamens, and a fruiting drupe with viviparous propagule. The genus consists of three species, including: C. australis, C. decandra and C. tagal. All species have similar leaves which are ovate to slightly obovate or elliptic-oblong, apices rounded or slightly emarginate, never apiculate, and yellow-green in colour. All three species are found in Australia.

Derivation of Genus Name

‘Ceras-opsis’ means horn-like appearance (in Greek), and refers to the small hypocotyl emergent from fruits of this genus.

Distribution

Ceriops are an Indo-West Pacific genus present in most mangrove stands from East Africa through Asia, the Malay Peninsula, the Philippines, to the south-western Pacific Islands and northern Australia.

Key to Australia's Ceriops Species

Three species of Ceriops are recognised in Australia’s mangroves across the northern coast from Western Australia, Northern Territory and Queensland. They are distinguished by shape of petal lobes, relative length and width of the peduncle, shape of the calyx tube, and ribbing on the hypocotyl.

Ceriops Key

Community Volunteers

A key feature of MangroveWatch is its close partnership between community volunteers and scientists from the James Cook University’s Mangrove Hub. Together they are systematically recording basic data as video and still imagery for assessments of estuarine habitat health.

Armed with expert support, training and advice, MangroveWatch volunteers in key regions are actively contributing to the monitoring of local estuaries and shorelines. An important goal in this phase of the program is to develop a network of like minded groups with the aim of producing public documents that describe important issues affecting local estuaries and mangroves, and their overall health.

Getting Involved
