Clermontia oblongifolia subsp. brevipes grow as shrubs or trees, typically 2–7 meters tall, and are found in terrestrial and epiphytic forms. Its stems are light gray or light brown, repeatedly branched, spreading, and feature a solid pith with white, viscous latex. The leaves are simple and alternate, with oblanceolate blades measuring 6–11.8 cm in length and 1.6–3.6 cm in width, characterized by dark green, glossy upper surfaces and very pale green, dull lower surfaces that are pubescent on the veins. The inflorescences, either glabrous or pubescent, have peduncles and pedicels measuring 0.4–1 cm and 1–2 cm in length, respectively. The flowers are bisexual, epigynous, zygomorphic (bilaterally symmetric), resupinate, and protandrous. The hypanthium is 1.1–1.4 cm long, with a synsepalous calyx, forming a hemispheric to obovoid structure. The perianth is 6–7.5 cm long and glabrous, with 1.8–2.5 cm long lobes. The stamens are syngenesious and either included or exserted, with purple anthers that open introrsely. The ovary is inferior, 2-carpellate, and 2-loculed, leading to a slender, terete style topped with a 2-lobed stigma. The seeds are numerous, tiny, dark brown or black, and have a minutely foveate-reticulate surface, containing a straight, short to spatulate dicotyledonous embryo within oily endosperm. It occurs within montane cloud forests at elevations of 1220–1280 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.
