Taxonomic notes

Two varieties, the type and brevifolia K.M. Lan et F.H. Zhang 1984 (no syn.), native to Guizhou (Farjon 1998).

Syn. for the type variety: Podocarpus argotaenia Hance 1883, Nageia argotaenia (Hance) Kuntze 1891, Cephalotaxus argotaenia (Hance) Pilger 1903, Podocarpus insignis Hemsl. 1885, Nageia insignis (Hemsl.)

Description

"A shrub 2-7 m. tall, with spreading branches. Branchlets light olive-green. Leaves 3-11 cm. long by 6-11 mm. wide, leathery, straight, spreading slightly forwards, with 2 white stomatal bands below nearly as broad as the marginal bands, apex bluntly acute or obtuse. Male strobili in groups of 1-3 at tips of branchlets, 5-6 cm. long, with 2-5 pollen sacs. Female cone ovoid or somewhat globose, light olive-green at first, 2-2.5 cm. long by 1.3 cm. wide. Seed to 1.3 cm. long" (Silba 1986).

Distribution and Ecology

China: Fujian, Gansu, Guangdong, Guangxi, Guizhou, Hubei, Hunan, Jiangsu, Jiangxi, Sichuan, and E. Xizang (SE Tibet); Laos; Vietnam (Farjon 1998, Averyanov et al. 2014). Although it is reported to only be hardy to Zone 9 (cold hardiness limit between -6.6°C and -1.1°C) (Bannister and Neuner 2001), the distribution shown here suggests that cold tolerance likely varies considerably with provenance, with more northern/continental populations likely to show a higher tolerance.

Distribution data from GBIF (2022). A. argotaenia is red.
