Panicum fauriei var. fauriei is a cespitose annual grass that grows 2 to 46 cm tall and features usually branched, puberulent culms with puberulent or short-pilose nodes. Its leaves are simple, alternate, and cauline, with blades measuring 1.5–12 cm in length and 0.1–0.4 cm in width, often involute and pilose on the upper surfaces while puberulent on the lower surfaces. The inflorescences are panicles 1–11 cm long, with a puberulent or sparsely pilose axis and branches that are usually appressed and puberulent or pilose. The anthers measure 1.0–1.2 mm in length. The spikelets (pictured) are 1.5–2.3 mm long, acute, and glabrous, with short-pubescent glumes and the first glume as long as the spikelet. The first floret is sterile, with a glabrous or short-pubescent lemma towards the apex, and the second floret matures to a dark brown color, elliptic, smooth, and glossy. The fruit is a caryopsis. It occurs in dry, open, often rocky habitats, including lava flows, rocky shores, raised coralline reefs, and dunes between 0-400 meters.
Bean-shaped (Reniform): Resembling the shape of a kidney or bean.
Square or Oblong: Angular shape with all sides more or less equal or longer than wide.
Triangular: Three-sided shape, broadest below the middle.
Elliptic: Rounded at both ends. shaped like an ellipse or oval.
Ovate or Obovate: egg-shaped, broader at one end.
Linear: Extremely long and narrow, with sides usually parallel.
Round: Appears circular, with length and width roughly the same.
Cardioid (Heart-Shaped): One edge has a prominent double curve into two lobes.
Cylindrical: A cylinder with parallel sides and a circular cross-section.
Discoid: Resembling a disc or plate with two relatively flat surfaces.
Fusiform: Spindle-shaped, tapering at both ends.
Globose: Spherical.
Lenticular: Resembling a lens with two convex surfaces.
Ovoid: Egg-shaped.
Plano-convex: Having a flat ventral (planar) surface and a curved dorsal (convex) surface.
Polygonal: Having more than three flat faces meeting at angles.
Sectoroid: Resembling a segment of an orange with two relatively flat faces and one curved face.
Subglobose/ellipsoid: Inflated shape but less than spherical.
Trigonous: Having three faces that meet at a distinct angle; triangular in cross-section.
Endangered species (E) are species that are so rare they’re in danger of becoming extinct.
Threatened species (T) are species that are likely to become endangered within the foreseeable future throughout all or a significant portion of their range.
Species of Concern (SOC) are species about which there are some concerns regarding status and threats, but insufficient information is available to list the species under the Endangered Species Act (ESA).
Plant Extinction Prevention (PEP) is a state status for rare plants that focuses its efforts on species that have fewer than 50 remaining wild individuals.
Orthodox seeds (desiccation-tolerant): can be dried to an internal seed moisture of less than 12% water and stored at freezing temperatures.
Intermediate seeds (temperature-sensitive) tend to age faster than orthodox seeds and may have only a 5-year lifespan when stored at -20°C. They are recommended for storage at 5°C.
Recalcitrant seeds (desiccation-sensitive): cannot be stored in a conventional freezer as they cannot survive after drying and/or freezing at -20°C. They are recommended for cryopreservation storage.
