Information
Low to tall tree, generally 12–24 m. in height, with a straight not much branched trunk and a rather small crown, the final branches terete, grey, with scattered subprominent lenticels. Leaves of mature trees with blades narrowly elliptic to elliptic-lanceolate, acutely acuminate, 6–19 cm. long, 2.3–7.6 cm. broad, coriaceous, nearly or quite glabrous on both surfaces except for well-spaced adpressed scales (appearing often as small pits under a hand lens). Panicles mostly terminal to the final branches, relatively large and fairly loose with very numerous small white flowers. Drupe narrowly ellipsoid to ellipsoid. Fig. 3 (p. 11).

Notes
The genus Steganthus, into which Knoblauch finally placed this species, is supposed to differ from Olea in having the æstivation of the corolla segments imbricate and not induplicate-valvate. For the following reasons it is here retained in Olea: (i) so far as can be determined by dissection of herbarium specimens the æstivation varies sometimes in a single flower, one segment being very slightly imbricate at one stage of the bud and the opposite segment induplicate-valvate — and at most the imbrication is very slight: (ii) the species is in many characters very similar to Olea hochstetteri which has been consistently retained in Olea.
