Description edit

Meiogyne cylindrocarpa is an evergreen rainforest plant with an open habit. It will grow to 10 m (33 ft) high, and perhaps 20 m (66 ft).[5] The dark green leaves are held on petioles about 1.5 to 3 mm (0.06 to 0.12 in) long, and measure up to 9.6 cm (3.8 in) long by 4.3 cm (1.7 in) wide, with 7 to 13 pairs of secondary veins.[5][6] They are glossy above and glabrescent (minutely hairy) underneath.[5]

The flowers may be solitary or paired,[5] with six fleshy, triangular petals arranged in two whorls of three. The outer petals measure up to 10 mm (0.39 in) long by 7 mm (0.28 in) wide.[5]

The fruit are elongated and cylindrical in shape. They measure up to 3.3 cm (1.3 in) long and 1.6 cm (0.63 in) diameter, and are initially green, becoming orange or red when ripe.[5] They are edible and sweet and have been compared to a sapodilla with a floral flavour.[7]

Propagation edit

Fingersop is typically propagated by seeds, taking anywhere from two weeks to six months to germinate. Plant seeds about a quarter inch deep in moist, well drained soil, and do not allow to dry out, the embryos are rather small and are encased in a thick seedcoat, so a small amount of mold in the younger stages can be beneficial for faster germination. Seedlings of M. c. subsp. cylindrocarpa tend to be smaller, with a bushier form then M. c. subsp. trichocarpa, which is more erect. Trees bear fruit after five to six years, but when grafted, will produce much sooner and develop a smaller, more compact form.
