Description:

Wollastonia remyi is an annual herb with erect stems that are 50-60 cm long. The stems are erect and reach 50-60 cm in length. The leaves are simple and petiolate, with ovate blades measuring 1.3-7 cm long and 1-5 cm wide. They are thin and herbaceous, with both surfaces strigillose. The leaf margins are deeply dissected, ranging from scarcely noticeable basal lobes to being deeply lobed nearly to the midrib. The petioles are 0.6-4 cm long. The flower heads are solitary or occur in clusters of 2-3. The outer involucral bracts are often purple near the base, lanceolate, 3.5-7 mm long, and 1.2-2.2 mm wide, with attenuate apices and strigillose surfaces. The chaffy bracts are often purple near the apex. Each head contains 5-8 ray florets, with ovate rays, 3-5 mm long and 1.7-4.2 mm wide. The disk florets number 20-35 per head, measuring 2.5-2.9 mm long, with anthers 1.2-1.4 mm long. The pappus consists of short, deciduous awns. The achenes are tuberculate, with wings about 0.3 mm long. Ray achenes measure 1.9-2.3 mm long and 1.1-1.6 mm wide, while disk achenes are 1.9-2.4 mm long and 1-1.4 mm wide. It occurs in dry shrublands and forests on steep slopes, rocky ledges, and talus slopes.

2D Seed Shapes

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.

3D Seed Shapes

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.

Federal Status

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.

Storage Behavior

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.
