Heliotropium anomalum var. argenteum is a prostrate subshrubs that sometimes forming mats. The stems are prostrate, decumbent (lying on the ground), or sometimes ascending, producing many short side branches along the length of the main stem at 1-10 dm long, flowering stems ascending to erect. The leaves are distributed along the stem or, on young or flowering stems, densely clustered toward the tips and appearing whorled, thick but not fleshy, linear-lanceolate to spatulate at 1-5 cm long, 0.1-0.8 cm wide, densely soft, silky, appressed villous, gradually tapering to base. The flowers are sweetly fragrant, in short, congested, bracteate cymes 0.8-1.3 cm long, peduncles 1.5-6.5 cm long. The calyx is stiff, deeply 5-lobed, the lobes linear, unequal, 1-2 usually slightly broader than others at 2.5-3.5 mm long, closely appressed, and silky pubescent. The corolla is white to pale purple, funnelform, 5-6-lobed, twice as long as the calyx, 6-11 mm long, the tube 5-8 mm long, appressed villous externally, especially on the tube. There are 4 nutlets, 1-seeded, obovoid, slightly compressed at 1.3-1.6 mm long. It is found in sandy costal areas.
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.
