Alyxia dolioliflora Guillaumin (1958: 398) View in CoL .

Holotype:— NEW CALEDONIA, Two miles south of Pouembout, elev. 200 m, 16 July 1952, MacMillan 5108: P [ P00072136 !]; isotypes: A [ A02180217 !], BISH [ BISH500605 ], E [ E00086582 ], K [ K000894167 !], L [ L0004670 !] ( Figs 3 View FIGURE 3 , 5 View FIGURE 5 )

Species circumscription: — Alyxia dolioliflora View in CoL was considered as a distinct species by Boiteau (1981), and then included in A. tisserantii View in CoL by Middleton (2002). We follow Boiteau (1981) and keep it as a distinct species characterized by linear leaves, red bark, and fruit articles longer than they are wide. Some specimens (e.g. MacKee 16935, Munzinger 7856) of A. tisserantii View in CoL s.l. (as circumscribed here) can be confused with A. dolioliflora View in CoL . However A. dolioliflora View in CoL differs from A. tisserantii View in CoL by a longer corolla tube (2.5–4.1mm vs 1.1–2.1 mm), and longer fruit articles (8–9.5 mm vs ca. 4.2–5.1 mm). Alyxia dolioliflora View in CoL is most similar to A. minimiflora and A. rosmarinifolia View in CoL , but differs from both by a longer corolla tube (2.5–4.1 mm vs 0.8–1.6 mm), and from the former by being entirely glabrous. As circumscribed here, the species grows only on serpentinites, at the low altitude foot of ultramafic mountains in the central part of the western coast of Grande Terre. In this region, it is easily recognizable as it forms typical shrubs with erect linear leaves. One must however be careful, as it can be confused with some forms of A. tisserantii View in CoL , at the margins of its distribution. A closer look at the fertile parts then becomes conclusive.

Distribution and habitat:— A. dolioliflora is distributed from Poya to Kaala-Gomen, at low altitude (0–300 m elev.) on ultramafic substrates. It grows mainly in shrublands.

Phenology:— From herbarium specimens and pictures available, A. dolioliflora is flowering and fruiting from October to July, and seems to be sterile in August and September.
