Summary

Description
English: Photographed at Otari Wilton's Bush, Wellington, New Zealand.

Threat Status: Nationally Critical. Family: Pennantiaceae. Distribution: Endemic to Great (Manawa Tawhi) Island, Three Kings Island group. Habitat: Coastal Forest. Sturdy, multi-trunked tree 5-8 x 4 m tall. Bark greyish, tessellated. Young branches and branchlets lenticellate. Petiole 25 mm long. Leaves subcoriaceous, glabrescent, 120-160 x 70 -100 mm, oblong to obovate, in exposed conditions distinctly recurved, otherwise flat, margins entire, apex obtuse, rounded, or slightly emarginate; base cuneate to obtuse; lateral veins of underside subtended by axillary hairy, pocket-domatium. Inflorescence usually ramiflorous or cauliflorous, rarely terminal, 80-120 x 40-120 mm. Male flowers unknown. Female flowers 1.5 x 1.5 mm, petals 2.6 mm, greenish white, stamen filaments in bud kinked sideways, straightening at anthesis, 1.5 mm long; anther 1-1.4 mm, pollen usually malformed and sterile. Ovary barrel shaped, 2.8 x 2 mm; stigmatic ring 1.5-1.8 mm diam., crested into 3 triangular plates. Fruit ellipsoidal, 10 x 4.5 mm, flesh purple; stone 9 x 3.5 mm. Flowering: October-November. Fruiting occurs between January and April in cultivated material. Ripe fruit has been seen in the wild during February and March. Though the only known tree is functionally female, occasional viable fruit is now known to be produced both in the wild and in cultivation. However, if pure seed is desired, plants should grown well away from kaikomako (P. corymbosa) otherwise hybrid seed will be produced. This tree can also be grown from cuttings and basal portions of new stem stuckers. Neither media is easy to strike, and so until recently, this species was rarely seen in cultivation.

Only one tree occurs in the wild. Initially P. baylisiana and indeed all other Three Kings endemic plants were at serious risk from goats. These were successfully eradicated in 1946. Since then the tree has persisted despite periodic storm and drought damage which may kill entire trunks. However, being female the tree was until recently considered functionally extinct. Apparently viable fruits were first found in the wild in 1989, and these, along with fruiting cutting grown plants in New Zealand provide one source of securing the species. However, until such time as more trees occur in the wild, P. baylisiana remains seriously at risk of extinction through natural events such as storms or senescence through old age.
