Clifton's Anguloa

Clifton's Anguloa, Anguloa cliftonii, is a striking terrestrial orchid in the family Orchidaceae native to the cloud forests of the Andes in Colombia, Ecuador, and Peru. The genus Anguloa, known as cradle orchids or tulip orchids, is celebrated among orchid enthusiasts for its large, tulip-shaped, waxy flowers that rock gently when moved, simulating the movement of a bee—a presumed pollination adaptation. The flowers of Anguloa cliftonii are creamy white to pale yellow, often with pink or rose spotting, and are produced singly on erect peduncles arising from the base of large, pleated pseudobulbs. The plant is a cool-growing epiphyte or lithophyte found in humid montane forest at elevations between approximately 1,500 and 2,500 meters in the Andes. Anguloa species are pollinated by male euglossine bees attracted to fragrant compounds. The cloud forest habitats of the Andes are among the world's most biodiverse ecosystems and simultaneously among the most threatened, subject to deforestation for agriculture, cattle ranching, and coca cultivation. Many Andean orchid species are also threatened by over-collection for the horticultural trade. Anguloa cliftonii is cultivated in specialist collections and is the subject of conservation concern in its native range.

Common White Heart-Leaf Aster

<em>Eurybia divaricata</em>, commonly known as the common white heart-leaf aster or white wood aster, is a perennial flowering plant in the family Asteraceae. Its conservation status is listed as Not Evaluated by the IUCN. The species is native to eastern North America and has also been recorded in parts of Europe, where it grows in shaded woodland environments, forest edges, and disturbed habitats with partial to deep shade. It typically flowers in late summer and autumn, producing numerous small white daisy-like flower heads with yellow centers that age to reddish-purple, creating a striking two-toned effect across a single flowering colony. The plant grows from a creeping rhizome and typically reaches 30–90 cm in height, forming loosely spreading colonies in suitable conditions. Leaves are heart-shaped at the base, providing the basis for the common name. <em>Eurybia divaricata</em> is considered a shade-tolerant woodland specialist that thrives in nutrient-poor soils under closed forest canopy, making it a useful indicator of relatively undisturbed eastern deciduous forest understory. Biological traits including average lifespan, precise height, and mass remain poorly documented in standardized databases. Ecologically, the white wood aster provides late-season nectar and pollen resources for pollinators including bees and butterflies at a time when few other woodland species are flowering, making it a valuable component of woodland biodiversity across its native and introduced range.
