Syzygium phaeophyllum is an extremely rare and hardly researched plant species from the myrtle family (Myrtaceae). It is endemic to the Fiji island of Taveuni and is only known from two collections from 1933 and 1934.

features

Syzygium phaeophyllum is a tree with smooth bark that reaches a height of 6 m. The stiff, stem-round branches are brownish. The flattened petioles are 6 to 10 mm long. The elliptical, leathery leaves are 6 to 8 cm long and 2.5 to 4 cm wide. They are slightly narrowed at the base of the leaf and pointed at the tip. The slim, narrowed tip of the leaf is about 1 cm long and slightly pointed. The leaf blade is entire and almost rolled up at the edges. The rib is slightly furrowed above and protruding below. On each side there are seven secondary veins, which protrude both on the leaf surface and on the leaf undersurface and converge in an irregular vein 2 to 4 mm within the edge. A second collecting artery often runs parallel to this. The 5 to 9 cm long, terminal inflorescences are composed of panicles and many-flowered. The side branches are somewhat flattened, the bracts dropping off prematurely. The flowers are often arranged in two or three terminal clusters. They are sessile or very short-stemmed. The leathery, cup-shaped, erect calyx is 3 to 4 mm long and 3 to 5 mm in diameter. The edge of the petals is very short. The wavy calyx rim has four small round lobes. The obovate, membranous petals are about 2 mm long. The stamens are numerous. The stamens in the bud are 2 to 3 mm long. The anthers have a diameter of approximately 0.5 mm.

status

The material marked as isotype dates from December 1933. The holotype was collected on January 8, 1934 in a dense forest on the edges of a lake east of Somosomo at an altitude of between 700 and 900 m. No specimen has been known since then. The IUCN classifies the species as " critically endangered " and estimates the population at fewer than 50 specimens.

Systematics

Syzygium phaeophyllum was first described in 1936 by Albert Charles Smith as Eugenia durifolia . In 1942 the species was put into the genus Syzygium by Elmer Drew Merrill and Lily May Perry as Syzygium durifolium . Since this name was given to the species Syzygium hallieri from Borneo as early as 1939 , the authors Merrill and Perry used the new name Syzygium phaeophyllum in 1945 .
