Description:

Cyrtandra filipes is a shrub approximately 1 meter tall, with stems that are few-branched, rounded to angular, and covered with pubescent multicellular hairs or are nearly hairless (glabrate). It has simple leaves arranged in whorls of 3–4 per node, or occasionally opposite, often clustered at the stem’s upper 3–7 nodes. The leaves at each node are unequal but symmetrical, ranging from oblanceolate to elliptic, 10–21 cm long and 2.5–6 cm wide, with an acuminate or rarely obtuse apex and a cuneate to attenuate base. The surfaces of the leaves are very sparsely strigose or nearly hairless, with the blades being thin and flaccid. It produces solitary flowers or occasionally in pairs within cymes, emerging from the leaf axils. The flowers are moderately to densely puberulent or occasionally nearly hairless, with peduncles and slender pedicels. The calyx is zygomorphic (bilaterally symmetric) and fusiform in the bud, becoming pale green and thin during anthesis. The corolla is usually bilabiate and white, with a subcylindrical tube curved near the middle. It has five stamens, with two upper fertile stamens and the rest being staminodial. The ovary is superior, glabrous, oblong-ovoid, with parietal placentation. The fruit is a fleshy or firm, narrowly ellipsoid, white berry, often tipped by the persistent stylar beak, containing numerous ellipsoid, minute seeds with a reticulate surface, usually 0.3-0.4 mm long. It is typically found in wet gulches and along streams in mesic valleys around 220 meters.

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.
