Scientific Name:Cyanea kuhihewa Lammers

TYPE: HAWAIIAN ISLANDS. Kaua'i: Hanalei District, Limahuli Valley, east side of ridge separating Limahuli and Hanakapl'ai Valleys, above major waterfall, along main stream, and climbing above numerous small waterfalls, lowland wet mixed forest, undisturbed, plants on NW-facing aspect above flood zone, 520 m, 10 May 1991, Wood, Wichman, Perlman & Marr 0820 (HOLOTYPE: PTBG; ISOTYPES: BISH, F, PTBG, US).

LANDS. Kaua'i: Limahuli Valley, below Honoonapali, above waterfall, in lowland wet forest, 1900 ft, 24 Jun 1994, Perlman, Wood & Wichman 14257 (F, PTBG); Limahuli Valley, east side of ridge separating Limahuli and Hanakapl'ai valleys, 520 m, 6 Aug 1991, K. R. Wood 1105-A seeds only (PTBG).

Etymology: The specific epithet is the Hawaiian verb kuhihewa, meaning "to suppose wrongly, to err in judgement, to mis- take a person for someone else" (Pukui & Elbert, 1971). It is given in allusion to the original confusion of this species with C. linearifolia

Relationships: Despite their similarity in leaf shape, the new species is not closely related to C. linearifolia. The two may be distinguished by the features listed in Table I. Note that even in foliar features there is a useful distinction: the leaves of C. linear- ifolia are strongly revolute, while those of C. kuhihewa are flat or at most show some minor revolution of the margin.

As noted above, the new species belongs to sect. Hirtellae, while C. linearifolia is a member of sect. Delisseoideae. Within the Hirtellae, C. kuhihewa seems most closely related to C. recta (Wawra) Hillebr., as they are similar in the length of the petiole and its length relative to the length of the lamina, number of flowers per inflorescence, length and posture of the peduncle, size and shape of the hypanthium, length and diameter of the corolla tube, length of the filament tube, and length of the anthers. Cyanea recta differs from C. kuhihewa in its pubescent stems, narrowly elliptic lamina pubescent beneath, stouter (2.2-2.7 mm) petioles, shorter (7-8 mm) rachis, longer (13-19 mm) pedicels, shorter (1.4-1.5 mm) wider (1.3-2 mm) calyx lobes, shorter (13- 14 mm) dorsal corolla lobes just 2/5-1/2 as long as the tube, shorter (12-15 mm) ventral corolla lobes, and broader (3.3-3.4 mm) anther tube.
