- Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI). Field Notes: Specimen collected from shaded area along stream in South Cumberland State Park (Grundy County, TN). Laboratory Analysis: Body: Large leaves emerging from underground rhizome. Size: 63 cm Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves: Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History: Diploid sporophyte dominant generation. Haploid spores germinate into heart-shaped, haploid, gametophyte. Water required for fertilization; no seed is produced. Diploid zygote develops into sporophyte.
