Leaves: Leaves simple. Alternate. Blades oblanceolate to obovate or oblong–obovate, 9–26 cm long, 2–7 cm wide. Apex acute or occasionally short-acuminate. Base attenuate. Upper surfaces with somewhat prominent and impressed lateral and tertiary veins, glabrate; lower surfaces with slightly raised veins, densely pale brown or rarely whitish tomentose, sometimes glabrate; blades subcoriaceous. Margins entire, somewhat revolute. Lateral veins 15–22 pairs. Petioles 1–3(–5) cm long. Stipules absent.

Flowers unisexual (and the plants dioecious), pedicels ca. 1–2 mm long. Calyx cup-shaped, sepals 5, distinct or 2 of them basally connate, 2.2–4.5 mm long, densely pale brown tomentose, margins ciliate. Corolla of 5 petals, cream, 13–16 mm long. Stamens 5, alternate with the petals, distinct; filaments 7–9 mm long, those of pistillate flowers ca. 3.5 mm long; fertile anthers 2.2–2.8 mm long, those of pistillate flowers ca. 1–1.5 mm long. Ovary superior, 2(3)-carpellate, 2–3-celled, on a short gynophore, placentation parietal; ovules numerous, in 2 rows per placenta; style 1; stigma capitate.

PROPAGATION/CULTIVATION

  • The fruits of Pittosporum hosmeri are cube-shaped capsules. These capsules are large and range in size from 1 to 3 inches long. They are fuzzy and brown when mature. The capsules open slowly to reveal the orange or red inner surface. Each capsule contains 40 to 45 seeds arranged in two rows within the capsule. The kidney-shaped seeds are range in color from black to reddish black. Each seed is 1/4 to 3/8 inch long. Fruits of Pittosporum hosmeri are generally ripe in the winter. Woolliams reports that green fruit will often open if stored in a plastic bag. Koob noted that he has only has success with ripe fruit; he has been unsuccessful with both seeds from green fruit and with stored seeds. Culliney and Koebele found that viable seeds cannot be obtained from green fruit even when mature. Only fresh seed from newly opened ripe fruit germinated. Their procedure is to extract the seeds from the capsules and immerse them in a room temperature solution of 9 parts water to 1 part household bleach for 1/2 hour. After the seeds are removed from the bleach solution, they are soaked in tap water for a day using just enough water to cover the seeds. The seeds are sown on the surface of wet vermiculite in sterilized containers. The containers must have good drainage. The seeds are covered with a 1 inch layer of dampened green sphagnum moss. Culliney and Koebele found that Pittosporum seeds took many months to sprout. Koob reports sowing the seeds on the surface of peat-based soil-less potting mix which is kept moist, but not wet. In his experience, the first seeds take about 9 months to germinate, but all germinate within a month or so after the first ones. Obata reports that Pittosporum species set very few seeds and that many seeds lack embryos. Artificial pollination did not result in additional viable seed. (Culliney 1999; Koob 2002; Lamb 1981; Obata 1997a; Obata 1997b; Wagner 1999; Woolliams 1976)
  • There is no published information on successful cutting propagation of any Hawaiian Pittosporum species. Criley reports very low percentages in rooting tip cuttings using total auxin concentrations ranging from 4,000 parts per million (ppm) to 6,000 ppm under 30% shade with an intermittent mist system. However, Adams obtained 100% rooting for the 3 cuttings he tried. These were 6 inch long semi-soft tip cuttings. They were treated with Greenlight talc containing 0.1% IBA. He used a rooting mixture of 1 part peat to 4 parts. The cuttings were rooted in a propagation structure with a clear Lexan roof using a misting system. The mist cycle was 30-45 seconds every 30 minutes. It took six weeks or more for the cuttings to root. (Adams 2003; Criley 1998; Criley 1999) [Data from Herring, E. C., & Criley, R. A. (2003).
