Report by Connie Barlow, thanks to help from Garrie Landry, Herbarium Curator, University of Louisiana at Lafayette
SIGNIFICANCE OF THIS SITE (Briarwood Preserve, Saline LA):1. Confirmed example of a Torreya taxifolia that was male in its youth, but then also began to grow female cones that became viable seeds.
2. This is only our third example of a specimen "naturalizing" (establishing seedlings) into the surrounding forest outside of Florida. The previous examples are at Biltmore Gardens (Asheville, NC) and at Harbison House (Highlands, NC)
3. This tree is likely a distinct genotype, and thus important for us to duplicate by rooting its branchlets and (ideally) sending seeds of different genotypes to be planted nearby in order to improve genetic diversity within the developing "grove".

I first saw the tree in the mid 1970s when I was an undergraduate student. At that time I learned it was a male tree. Several years ago I visited the preserve and spent a day with the caretakers who told me that in the last 10 to 15 years this tree began producing female cones as well and ultimately viable seeds. I was shown a number of well-established volunteer seedlings growing near the parent plant.

One is a seed bearing male which has four seeds on it this year. In addition, I would like to get your input on how to best encourage our seedlings to grow; most are about a foot tall and have been that way for years.

RESULTS OF CONNIE'S ONLINE RESEARCH (July 2018):
I found online many photographs (and biographical information) of the famous naturalist who planted the Torreya, Caroline Dormon. Plus I found two photos of the tree itself:

CAROLINE DORMAN (1888 - 1971) was a world-renowned naturalist, author, artist, and the first woman to be hired by the U.S. Forest Service. She wrote botanical books the titles of which, taken together, tell of her interests: Wild Flowers of Louisiana (1934); Forest Trees of Louisiana (1941); Flowers Native to the Deep South (1958); and Natives Preferred (1965). Her last work, Bird Talk, published in 1967 when she was 81, is an elegy to the diminishing number and species of birds in her pine forests, victims to pesticides, clear cutting, and the sterile pine plantation system.
