Bracteocarpus kawaii (Hayata) A. V. Bobrov & Melikyan; Podocarpus kawaii Hayata.

Trees to 40 m tall; trunk to 2 m d.b.h.; bark superficially dark brown or blackish; weathering gray; red-brown and granular fibrous within; flaking in thin strips; crown spreading; branchlets stiff; erect. Juvenile leaves borne at 60-75° to branchlet axis; 0.2-0.7 mm apart (branchlets 3-4 x 1.2-1.6 cm in outline); sessile; green or ± glaucous; linear; falcate to S-shaped; 6-10(-17) x 0.9-1.2 mm; stomata arranged in 2 whitish rows on abaxial surface; base decurrent; margin entire; apex obliquely incurved-apiculate; apiculus 0.2-0.3 mm. Adult leaves spreading; needlelike; falcate; 0.1-1.5 x 0.4-0.6 mm; base keeled; apex acute. Pollen cones ovoid or ellipsoid and ca. 5 mm before shedding pollen; finally cylindric and 6-12 x 2-

2.5 mm; microsporophylls 2-4 mm; apex triangular; acute or apiculate. Seed-bearing structures solitary or paired; usually only 1 maturing; bractlike leaves at base of peduncle 1-3 mm. Receptacle glaucous; red when ripe; obovoid; 3-4 x 1-2.5 mm Epimatium initially green with bluish tinge; red when ripe. Seed globose or subglobose; 5-6 x 4-6 mm. Pollination Feb-Apr; seed maturity Oct-Dec.

Montane rainforests (Hainan); mixed evergreen broad-leaved forests (mainland); or in pure stands; in valleys of mountain streams on slightly acid; montane yellow-earth; 400-1500 m. NE Guangxi (Jinxiu Yaozu Zizhixian); Hainan; S Yunnan; cultivated in Guangdong [S Cambodia; Indonesia; Laos; Malaysia; N Myanmar; Papua New Guinea; Philippines; Thailand; Vietnam; Pacific Islands].

A vulnerable plant in China and one of the most important forest trees in Hainan. The varieties recognized by de Laubenfels are distinguishable only by characters of adult leaves; much material in herbaria is juvenile and so identifiable only to species rank. Chinese plants were treated in FRPS as Podocarpus imbricatus Blume.
