Cyathodes straminea

Cyathodes straminea, also known as false-whorled cheeseberry, is a species of flowering plant in the family Ericaceae endemic to Tasmania, where it grows as an alpine to subalpine shrub (15–60 cm in height) with a spreading habit. The generic name Cyathodes was derived from Greek "Cyath" = cup and "odes" = like, referring to the ovary encircled by cup-shaped nectary.

Description

[edit]

Cyathodes straminea is a shrub with leaves arranged in pseudowhorls. Leaves are obovate-elliptic 7–16 mm long, 3-4.5 mm wide, often with a membranous margin, and a soft, blunt point. The upper surface is glabrous, but the lower surface is covered in white wax (glaucous) with prominent parallel veins (Fig.1). Petiole 1.6-2.4 mm long.[1] The flowers occur in summer in upper leaf axils (Fig.2) and have a strong cheesy smell, are white, bell-shaped and hermaphrodite (both male and female) with long corolla lobes and anthers exserted on thick filaments. They have 5-10 locules in the ovary,[2] developing into red, rounded, flattened fruits to 8mm wide, reputed to be edible (raw or cooked) (Fig.3).

Habitat

[edit]

Cyathodes straminea grows frequently in open shrubby subalpine heathland and woodlands on the Dolerite mountains of the northern, central and eastern parts of Tasmania above 1000m.[3] Usually found on medium and heavy (clay) soils in moist, rocky and windy sites, with well-drained conditions and is frost tolerant. Commonly associated with Eucalyptus coccifera, Orites revoluta, Helichrysum and Richea species.

Cultivation

[edit]

It requires a well-drained moist soil in a sheltered site. These plans are very susceptible to drought but can grow even in -7 °C. The seeds should be surface sown in ericaceous soil. It germinates within 1–2 months at 18 °C. Scarification will reduce the germination time and 2 or 3 periods of 4 – 6 weeks cold stratification, alternated with 4 weeks warm stratification can also help. [4]
