Disterigma campii
Habitat:
Disterigma campii is endemic to Ecuador, specifically known from the Sucumbíos and Pastaza provinces. It grows in premontane to montane cloud forests, at elevations between 1700 and 2347 m, often as a low epiphytic or terrestrial shrub in moist, shaded forest understories. This species is rare and known from only a few collections in its native range. 
Description:
Disterigma campii is a compact shrub, occasionally epiphytic, producing stems up to 0.5–2 m tall, densely covered with short hispidulous (bristly) hairs. Leaves are succulent when fresh, drying to thin-coriaceous texture, oblong-elliptic, measuring approximately 8–15 × (3–)5–8 mm, with rounded or obtuse apices. Inflorescences bear solitary, nearly sessile flowers. The cup-shaped calyx is about 5 mm long, with 4 deltate lobes. Flower corolla is broadly campanulate to subrotate, 5–6 mm long and 5–8 mm across, white, with lobes spreading or reflexed; stamens number 8, staminodes and style thick. The fruit is a spherical berry, about 10 mm in diameter, translucent white. 
Cultivation (informative):
Although Disterigma campii is rarely cultivated, if grown it would require conditions simulating its native cloud-forest habitat—cool, moist and shaded conditions, with substrate rich in leaf mulch and excellent humidity. Daytime temperatures around 15–20 °C, and night temperatures of 5–10 °C, with high humidity (above 80%) and regular moisture without waterlogging, would be suitable. Weak ericaceous-type acidic fertilizer during active growth may be used sparingly.
