Cyanea munroi is a short-lived perennial shrub 1 to 3.2 m tall. The stems are unbranched, sparingly branched, and muricate (studded with short rough points). The leaves are pinnately (with two rows of leaflets along the axis) divided, and the blades are 27 to 58 cm long and 14 to 32 cm wide. The leaves have 9 to 12 segments per side. The leaves are oblong (shaped basically like a rectangle), lanceolate (lance-shaped; much longer than wide, broadest below the middle), narrowly triangular, or narrowly ovate (egg-shaped). The petioles (a leaf stalk that attaches the blade to the stem) are 8 to 32 cm long. The inflorescences are 6- to 12-flowered, with peduncles (the stalk of an inflorescence or a solitary flower) that are 15 to 75 mm long. The corolla is purplish or greenish to yellowish white, often suffused (gradually spread through or over) or striped with magenta. The fruits are orange berries that are obovoid (inversely egg-shaped) to ellipsoid. It is found on steep slopes and valleys in mesic forests between 550-910 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.
