Florida torreya, stinking cedar, gopherwood (Hils 1993).
Type species of the genus Torreya. Syn: Tumion taxifolium (Arnott) Greene (Hils 1993).
Trees to 13(18) m; trunk to 80 cm dbh; "crown rather open-conical. Branches spreading to slightly drooping; 2-year-old branches yellowish green, yellowish brown, or gray. Leaves 1.5-3.8 cm, abaxial side with 2 scarcely impressed, grayish bands of stomates, rounded on adaxial side, emitting fetid odor when crushed. Pollen cones pale yellow. Seed (including aril) 2.5-3.5 cm; aril glaucous, dark green, streaked with purple" (Hils 1993).
USA: Georgia, Florida at 15-30 m elevation on river bluffs, slopes, and moist ravines along a 33-km stretch of the Appalachicola River (Godfrey and Kurz 1962, Hils 1993).
Zone 9 (cold hardiness limit between -6.6°C and -1.1°C) (Bannister and Neuner 2001).
14 m tall, 88 cm dbh, in a yard in Norlina, NC. Formerly, heights of 20 m were recorded among wild trees (American Forests 1996).
See Remarks; no wild trees are more than 35 years old, and the oldest specimen is probably in cultivation.
No use recorded and none likely to happen.
Formerly used for fuel, fence posts, and shingles (American Forests 1996).
It may still be possible to see the species in Torreya State Park, where only stump sprouts and saplings survive. To see a healthy tree, you must find it in an arboretum or ornamental planting.
The species is a rare endemic. Populations were thriving until the 1950s, but since then they have been decimated by fungal disease (Godfrey and Kurz 1962, Lee et. al. 1995). By 1962, only nonreproductive stump sprouts remained in the wild. In 1984, the Florida torreya was listed as endangered under the US Endangered Species Act. A recovery plan has been approved, and efforts are underway to reestablish this once thriving species in its native habitat. Approximately 1000 individuals were alive in 1996, but at that time, the responsible pathogen had not been identified. At this time, the continued survival of the species apparently depends entirely on plants in cultivation (McMahan 1989, Hils 1993, American Forests 1996).
The epithet "taxifolia" means "leaves like Taxus" (yew). Other species in the genus have leaves considerably longer that those of most yews, although that is probably fortuitous, as the other species were described after this one was named.
This is one of only two native U.S. conifers protected under the Endangered Species Act (the other is Cupressus goveniana var. abramsiana). Although you will sometimes see it called "the rarest conifer in the world," there are actually quite a few species more deserving of that title by having not only fewer individuals and a more threatened habitat, but also by receiving less attention and fewer resources devoted to their preservation. Compared to most of the world's endangered conifers, Torreya taxifolia is very well cared-for, and has a brighter future.
