Shrubs (1.5–) 2–5 m tall; stems usually few. Leaves opposite, borne on upper 4–8 nodes, elliptic, occasionally elliptic-oblanceolate, 14–24.5 × 5–7.5 cm, glabrate, upper surface glossy, dark green, lower surface pale green, margins serrulate, apex rounded and usually with acuminate tip, base attenuate, petioles 3–6 cm.

Marquesas Islands, uncommon, endemic to Nuku Hiva, Toovii Plateau to Mt. Ooumu, from 800 to 1150 m.
Cyrtandra nukuhivensis is known from montane wet forest with Metrosideros collina (J. R. Forst. & G. Forst.) A. Gray and Weinmannia marquesana F. Br. forest with diverse fern understory along with other shrubs and trees such as species of Cheirodendron, Coprosma, Crossostylis, Ilex, Melicope, and Xylosma.
IUCN Red List Category: Endangered EN B1ab (i,ii,iii) + 2 ab (i,ii,iii): B2: total area of occupancy less than 5000 km2 (ca. 340 km2). B1a, severely fragmented; B1b (i–iii), habitat continuing decline inferred. The suitable habitat for Cyrtandra nukuhivensis on Nuku Hiva (ca. 340 km2), is restricted to mountain slopes and summits, indicated as an endangered environment that is threatened by human activity (deforestation and fire), feral animals, and invasive plants, reducing the extent of the forest (Florence and Lorence 1997; Mueller-Dombois and Fosberg 1998; Meyer and Salvat 2009).

Cyrtandra nukuhivensis is delimited in a more restricted way than previously and is here considered to be endemic to Nuku Hiva. The Ua Pou plants are here considered a distinct, but closely related species.
