Description:

Lipochaeta succulenta is a suffruticose perennial herb with decumbent stems that root along the lower surface and occasionally erect or ascending. The stems can range from 50-150(-400) cm in length. The leaves are opposite, somewhat fleshy, appearing shrunken and wrinkled in dry material. The leaves are linear to elliptic-ovate, 6-12.5(-16) cm long, (1-)2-4(-6.5) cm wide, and can be glabrous to strigillose. The margins of the leaves range from entire to serrate, and the petioles are 0.2-1 cm long, with winged margins. The flowers are arranged in simple or compound cymes. The outer involucral bracts are occasionally purple near the apex, ovate, 3.2-5 mm long, 1.5-3.8 mm wide, sparsely strigillose, with an acute apex. The chaffy bracts are also occasionally purple near the apex. Each flower head contains 9-15 ray florets with ovate to oblong rays that are (3.8-)4.5-6(-7) mm long and (1.3-)2.3-3.3 mm wide. There are 25-40(-50) disk florets per head, with corollas that are 4-merous and 3.1-3.7 mm long. The anthers are 1.3-1.5 mm long. The pappus consists of connate scales forming an uneven corona tipped with short deciduous awns. The fruit is nearly smooth with a thick, corky layer. Ray achenes are 2.3-2.7 mm long and 1.2-1.7 mm wide, with wings approximately 0.5 mm long. Disk achenes are 2.2-2.9 mm long and 1.1-1.4 mm wide, with wings approximately 0.6 mm long. It occurs in coastal sites between 0-50 meters.

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.
